The Ultimate Guide To Creating A Greener Kitchen

When setting out to create a greener kitchen and home it’s hard to know where to start. Information overload is definitely a problem. Five minutes on Google and suddenly I have 42 checklists, 700 “green” products to buy, and if I don’t make the changes today I’ll be diagnosed with 6 different cancers within the year.Alright, that may be a bit of an exaggeration, but I’m sure you’ve experienced something similar. There is so much info out there it’s hard to know what to do.

Creating a greener kitchen environment

In our home I focus on making small changes each week to create a greener environment. One week it’s adding more organic produce to the shopping list. The next week we’re taking time to wash and recycle cans and jars.

In order to help you take small steps towards a greener home I’ve put together this guide to help you create a more sustainable, greener kitchen.

I’m not saying you need to dive in and make every one of these changes today. But pick one thing and implement that. Once you’ve mastered that, move on to something else. The path towards a more sustainable life is taken one step at a time.

For simplicity I’ve broken this list down into the 3 R’s; Reduce, Reuse, and Recycle.

Reducing kitchen waste

Food waste

Food waste is a major issue facing the world right now. In the U.S., it is estimated that 40% of the food produced is never even consumed.

When you think about all the water, energy, and time that goes into producing food, that’s a ton of wasted resources!

So what can you do to reduce food waste in your home?

We often end up purchasing more food than we need. This may be because we need a certain amount for a recipe and have no choice but to purchase more than we need. Or, maybe we just shop hungry (always a bad idea).

One way to reduce your food waste is to more carefully plan your cooking. Figure out what recipes you like that share similar ingredients and plan to cook them in the same week. If you don’t enjoy leftovers, learn to cook smaller quantities of food that are better suited for your household’s size.
Another way to reduce food waste is to store your food properly. When stored properly, food will last longer, giving you the chance to eat it before it spoils.

There’s an app for that

The USDA FoodKeeper app is a great way to learn more about the shelf life of various foods and how to store them properly. The best part about this app is that it goes well beyond produce, covering baby food, baked goods, condiments, and even meat. You should definitely take a minute and download the app. You’ll be amazed at how helpful it is.

If you do end up with extra produce that you know will go bad before you can eat it all, you can always freeze a portion for later. We do this in our home all the time with berries and bananas.

Consider composting

Inevitably you’ll have food that goes bad. At home composting can be a great way to put that spoiled produce to good use.

Earth911 took a tour of Singh Farms to learn the technical details about composting. If you’re interested in learning the science of composting click here.

The greatest benefit to composting is that you end up with nutrient rich soil that can be used to grow delicious new produce. To help you get started we put together a video on all you need to know about composting.

Cleaning products

We all have cleaning chemicals in our kitchen, frequently stuffed under the kitchen sink. Have you ever taken a minute to read through the ingredients? Unless you’re a chemist you probably can’t pronounce most of them.

When wiping down your kitchen, floor, and dishes, these cleaning chemicals often leave behind residue that will later come in contact with your hands and food. We recommend replacing these toxic cleaning products with natural ones that work just as well.

Lemon, baking soda, and vinegar are some of the best natural cleaners out there. Here are a few quick suggestions on how to use them to clean your kitchen.

Quick tips

Remove stains from food storage containers: Squeeze the juice from a lemon into the containers, then add a little baking soda. Rub the mixture into the stains. Let sit overnight if necessary.
Clean your microwave: Slice a lemon, put it in a bowl of water and microwave for 45 seconds. This should make stains easier to wipe away and eliminate unpleasant odors.
Clean your coffeemaker: Run the machine with equal parts water and vinegar. Halfway through the cycle, turn it off and let it sit for an hour. Then complete the cycle.
Unclog a drain: Pour 1/2 cup vinegar and 1/2 cup baking soda down the drain. Rinse with water.
Make glasses sparkle: Put one cup of vinegar in the bottom of your dishwasher before you run the cycle. After you run the dishwasher, your glassware shouldn’t be cloudy.
Remove stains from coffee and tea mugs: Fill mugs with one part baking soda and two parts water and let sit overnight. Scrub and rinse in the morning.
Remove burnt food from the bottoms of pots and pans: Sprinkle baking soda over the burnt areas, add hot water and let sit overnight. Scrub in the morning.
Remove odors from food containers: Simply rinse containers with baking soda and water to remove smells. Let sit overnight if necessary.
Clean spills in the oven: Scrub the bottom of the oven with steel wool and baking soda. (Note: If you have a self-cleaning oven, don’t use this method.)

Energy use

Though it doesn’t happen often, when you do need to purchase new appliances be sure to purchase energy efficient ones.

Energy Star rated products are the go-to choice when it comes to finding the most energy efficient appliances. They (Energy Star) have put together a great tool that allows you to put together a profile of your whole home. After you’ve created your home profile they’ll give you recommendations on how you can save energy.

According to the U.S. Department of Energy your appliances account for about 13% of your home’s energy use. Purchasing newer, more efficient models can save you a significant amount of money over the lifespan of the appliance. When you do replace your appliances be sure to recycle your old ones properly, but more on that later.

Reuse in the kitchen

Food Storage

When it comes time to store leftovers it’s important to use sustainable food storage, and glass and stainless steel are two good options.

Glass

Glass containers such as Pyrex and Glasslock are certainly among the best options available. Glass is a long lasting material and is microwave and oven safe.

In our home, we use this set of Pyrex storage containers daily. My favorite part about using these glass food storage containers is that you can cook your meal in them and then throw the lid on and stick the leftovers in the fridge for later. It doesn’t get much easier than that.

Stainless steel

Another great option is stainless steel. Stainless steel has the benefit of not breaking when dropped like glass containers do. (When I was 16 my mom baked my favorite cake in a glass pan. We took it to the park for a party and it got knocked off the table. Glass went everywhere and the cake was ruined. If it had been in a stainless steel pan, we still could have eaten it.)

Stainless steel containers are also completely recyclable. If they get bent out of shape you can take them to your nearest scrap yard and they’ll pay you for the metal.

Another great benefit of stainless steel containers is they can be set right on your stove top to heat up leftovers.

Plastic perhaps?

We are big fans of Preserve products which are almost all made from recycled #5 plastic. Preserve products are microwave safe, dishwasher safe, BPA free, and when you’re done with them they can be sent back to Preserve to be recycled. Image Credit: Preserve Products (Instagram)

If you can’t find a glass or stainless steel container for your food, there are plastic options that are better than others. We are big fans of Preserve products which are almost all made from recycled #5 plastic. Preserve products are microwave safe, dishwasher safe, BPA free, and when you’re done with them they can be sent back to Preserve to be recycled.

One last thing before we jump in to the recycling section. If you aren’t already, start using reusable shopping bags, preferably the canvas or fabric type rather than the plastic ones as there’s no recycling solution available for the large, reusable plastic bags.

Kitchen recycling

Plastic bags

I know I just mentioned using reusable shopping bags but inevitably you’re going to have plastic bags around your home that need to be recycled. Fortunately plastic bags can be recycled at most grocery and retail stores.

While this widespread access to plastic bag recycling is still relatively new, it’s become more and more popular as retailers have set their own sustainability initiatives.

What many people don’t realize is that grocery bags aren’t the only type of plastic bag that can go in these drop off bins.

Plastic bags are typically made from plastic #2 or #4 and can be recycled together. Here are a few other products made from these plastics that you can drop off in these bins.

Ziploc type plastic bags, as long as they are clean and dry.
Plastic, air filled, shipping pouches. (Just cut them and let the air out).
Plastic bread and bagel bags, as long as you empty all the crumbs out.

Find out more about plastic bag recycling and find a location near you by visiting our Plastic Bag Recycling Guide.

Cardboard and cartons

Most city curbside recycling bins accept cardboard so check with your local area collector. Image Credit: sevenke / Shutterstock

Most city curbside recycling bins accept cardboard. To make things easier on space in your own bin, be sure to break them down so they’re flat. Don’t worry about tape and other paper that’s attached to the cardboard as this will be removed during the recycling process.

Most city curbside programs also accept paperboard which is the cardboard-like box that holds cereal, pasta, and other boxed dry goods.

Frozen food boxes, a.k.a. waxed cardboard, unfortunately are not as widely accepted. These boxes require more work to recycle so check with your city or county to find out if you can place them in the recycling bin.

Another product to check on with your city is milk and juice cartons. Many cities do accept them though it is best to double check. Visit the Carton Council to find out if your city accepts cartons in your blue bin.

Appliances

Large appliances, like washing machines, clothes dryers, water heaters, ovens, stoves, refrigerators, freezers, furnaces, and air conditioners are a big source of waste in the United States. However they often aren’t that difficult to recycle.

In fact, if you are replacing an appliance with a new one the company delivering it will often take your old one for recycling. This service has made appliance recycling far easier over the last few years.

When you do replace an old appliance with an Energy Star model, you may be eligible for a rebate. Check the Energy Star rebate finder to see if you qualify.

If you need to recycle an old appliance, be aware that there are often fees to cover the cost of removing and properly disposing of the Freon commonly found in refrigerators, freezers, and A/C units.

Find out more about large appliance recycling and find a recycling location near you by visiting our Large Appliance Recycling Guide.

A homework assignment

As mentioned, cleaning chemicals often contain toxic ingredients that are hazardous to your health. Fortunately, the Environmental Working Group has put together some fantastic resources to help understand what cleaning products are hazardous.

If you’re looking for a first step to greening your kitchen this homework assignment below is perfect. In this assignment we’re going to figure out just how hazardous your cleaning products are. Here’s what to do:

  1. Pull out some of the cleaning products you use most frequently.
  2. Click here to visit EWG’s cleaning product search.
  3. Using the search bar at the top of the page, or the Product search on the left side of the page, look up your cleaning products.

How do your products rate?

Bill O’Reilly and Donald Trump chat about the end of the world

Faux News

Bill O’Reilly and Donald Trump chat about the end of the world

By on Jul 27, 2016Share

Presidential hopeful Donald Trump appeared on Fox News’ The O’Reilly Factor Tuesday night to clarify his stance on a few issues. On the list: Bernie Sanders? Liar! Federal minimum wage? Get rid of it! NATO? Who needs it! Job recovery? Never heard of it!

On climate change, the Republican nominee was especially verbose. Here’s his full exchange with Bill O’Reilly (emphasis our own):

O’Reilly: They said that you called climate change a hoax. Is that true?

Trump: I want clean air and I want clean water and if you look at what’s going on in China and all these other countries that talk but they laugh behind our back at what we are doing. We want clean air, we want clean water, I’ve got many environmental awards, believe me. I know what I’m talking about. But we’ve got to have crystal clear water and crystal clean air.

O’Reilly: But did you ever call climate change a hoax?

Trump: Wellll, I might have because when I look at some of the things that are going on — in fact, if you look at what was happening in Europe a few years ago where people were sending out emails, scientists practically calling it a hoax, and they were laughing at it, so yeah I probably did. I see what’s going on and you see what’s going on.

O’Reilly: Do you believe that manmade fossil fuels and gases have eroded the environment so that the sun is more intense on Earth? Because that’s the basic thing. Do you believe that’s happening?

Trump: Well, they’re saying manmade and I say it could have a minor impact but nothing, nothing to what they are talking about. And what it is doing is putting us at a tremendous disadvantage as a country, because other counties are not adhering to the rules, we are, and it makes it impossible for our businesses to compete.

O’Reilly: That’s true.

Rest of the world: Sigh.

Neither O’Reilly nor Trump appear to understand climate change or how it works. And despite Trump’s frequent assertion that he’s “won many, many environmental awards,” the only one on record was bestowed upon him by a golfing organization.

Green Road Trip Tips For The Summer

Ah, summer! The season of barbecues, picnics, camping, delicious fresh fruit and summertime adventures. One of my favorite things to do through the summer is take a road trip with family, friends and sometimes even a short solo journey. I find that road trips make for a relatively cheap and easy holiday option, allowing one to explore the interiors of a particular area and marvel at the beauty that summertime brings. Last year, I spent my summer in the Pacific Northwest, and the number of road trips I took increased exponentially. Sometime in the midst of summer and considering how much I was getting out onto the road, I decided that it was only fair to go about my little adventures in a more environmentally responsible manner a green road trip if you will.

Green road trip tips, for all seasons

These green road trip tips will keep your next summer road trip as eco-friendly as it is enjoyable. Image Credit: Monkey Business Images / Shutterstock

I’ve always been a pretty accountable and cautious person by nature, and so, I researched ways in which to make my journeys more “green”, and lessen their impact (directly and indirectly) on the beautiful surroundings I often cruised through. Today, I’m going to share with you some green road trip tips to keep your next summer road trip as eco-friendly as it is enjoyable.

The Car

Arguably, one of the best ways to keep your trip green is to maximize fuel efficiency. Before embarking on a long journey, make sure your car is fully tuned up. Sometimes overlooked factors, such as your tires not being fully inflated, can reduce fuel efficiency by a significant amount (not to mention, they make driving dangerous). Making sure your car is well maintained and suited for a road trip is vital, as a car in shape will retain its efficiency for a long period of time. More importantly, a well-maintained car aids safety, and safe driving practices are critical for long drives.

If you are renting a car for your trip, then consider renting one that is fuel efficient.  I’ve rented cars for longer journeys in the past, and trust me when I say it’s worth paying a little extra to get a vehicle with higher fuel efficiency.

The Load

Green road trip tip: avoid packing heavy and bulky items unless absolutely necessary. Image Credit: Youproduction / Shutterstock

Pack only as much as you need. Avoid packing heavy and bulky items unless absolutely necessary, and be sure to empty out your trunk of any items you’ve been storing in there that you won’t need for your summer road trip. Keeping your weight to a minimum will reduce the amount of gas consumed, and also save you some money over time. I recently learned that keeping things on the roof of your car can reduce efficiency up to 25%! Apparently, bike racks and luggage carriers will interfere with efficiency even when empty as they disrupt the aerodynamics of the car.

The Drive

Planning your route in advance will help you save fuel, as opposed to spontaneously “going where the road takes you”. In terms of the drive itself, here are some easy-to-follow steps that really do make a big difference in staying environmentally friendly:

When possible, opt for cruise control, as this is much better than constantly accelerating and braking.
Don’t idle! I remember driving to Seattle once, and seeing a “Stop Idling” sign at this large intersection. Even though the sign was very visible, most drivers were in fact, idling. Idling is tempting, but in reality consumes a lot of gas in a small amount of time.
Use as little air-conditioning as possible. I find this quite hard to do, especially during the peak of summer, but it’s worth a try during cooler evenings or while driving through long shaded areas.

The Activities

Apart from the journey itself, the activities you engage in throughout your road trip also contribute to the carbon footprint you leave behind. In terms of food, try and eat local. Consider frequenting farmers’ markets, or eating at local sustainable restaurants. Not only will you be helping the environment, but you’ll get to truly immerse yourself in your new surroundings and get an insider’s perspective. Packing low-carbon snack alternatives in reusable containers is a great way to stay healthy, and also reduce waste.

A great way to see some sights you might otherwise miss is to throw some walking and hiking into your road trip. This saves fuel, and is a fun activity to change things up during a road trip. Instead of using electronic devices to keep your mind occupied during those longer and bleaker drives, or during long pit-stops, try playing a game or two, or interact with fellow travelers. I’ve met some really interesting people at pit-stops, and have found that exchanging stories over a meal with fellow road-trippers is so much more fulfilling than staring at a screen. Even though it doesn’t seem like much, you’ll be saving some electricity, and reducing your personal impact on your surroundings, and who knows you might even enjoy doing it!

So the next time you’re planning a road trip, think about including these green road trip practices into your journey. After all, half of the enjoyment a road trip brings comes from the beauty of the environments we drive through — so it only makes sense that we do our part in preserving its splendor.

The next U.S. president could save or destroy the Arctic

The next U.S. president could save or destroy the Arctic

By on Jun 16, 2016Share

The next president will decide the fate of pristine waters 3,000 miles away from the Oval Office — a decision that would resonate for decades.

Nearly 400 scientists sent a letter Wednesday calling on President Obama to close the Arctic to the oil industry. Right now, Obama’s five-year draft plan for offshore drilling offers two lease sales, one in the Beaufort Sea in 2020 and one in the Chukchi Sea in 2022.

But it’s not just Obama who will determine the fate of the Arctic; his successor’s choices will outlast his or her tenure by a long shot.

For her part, presumptive Democratic nominee Hillary Clinton has indicated that she would not allow oil and gas drilling in the region.

On the other hand, Republican nominee Donald Trump hasn’t taken a formal stance on the issue, though he has indicated support for offshore drilling in the Atlantic and that he would “absolutely” drill in the Arctic National Wildlife Refuge. “I’m a big driller,” he’s said.

For drillers, the Arctic is about the long game: From the time the leasing bid occurs, it usually takes about a decade for drilling to actually begin. 

“You’re putting into motion a process that will rattle on for decades,” Tim Donaghy, a senior researcher at Greenpeace who focuses on offshore drilling, told Grist.

Even if the Arctic were opened, no company has managed to prove that wading into its icy waters is a smart financial investment. Any project in the Arctic is bound to face similar hurdles and the kind of opposition Shell saw from climate activists, who blockaded the mouth of a river to stall the company’s ice breaker last year. Shell, after a series of mishaps, announced last May that it was packing up after blowing $7 billion in Arctic waters.

The Arctic Circle contains an estimated 90 billion barrels of oil, equivalent to 13 percent of Earth’s undiscovered oil, to be exact. Drillers (and future presidents) may be hard-pressed to let go of such a buried treasure.

The Trump Files: The Time Andrew Dice Clay Thanked Donald for the Hookers

Mother Jones

<!DOCTYPE html PUBLIC “-//W3C//DTD HTML 4.0 Transitional//EN” “http://www.w3.org/TR/REC-html40/loose.dtd”>

Until the election, we’re bringing you “The Trump Files,” a daily dose of telling episodes, strange-but-true stories, or curious scenes from the life of presumptive GOP nominee Donald Trump.

On June 16, 1990, the day after Donald Trump missed a $43 million payment on bonds he used to finance Trump Castle, the mogul visited his Atlantic City casino for a blowout celebrating his 44th birthday. The party capped off a day that started with a pro-Trump rally held by casino employees—”Let’s stand behind our Donald, because he’s the father of our babies,” one worker urged the crowd. The rally featured a “professional motivator” to whip up the audience, and one worker presented the tycoon with a gift: an eight-foot-tall “rug portrait” of Trump.

The party at the Castle’s Crystal Ballroom was an over-the-top bash with bands, confetti, and a cheering crowd. Robin Leach, the host of Lifestyles of the Rich and Famous, walked out of a fake Trump Shuttle to act as hype man before other celebrities showed up in person and on stage. As then-Village Voice reporter Wayne Barrett described in his book, Trump: The Greatest Show on Earth,

Dolly Parton and Elton John appeared on giant screens to wish Donald a happy birthday, with Parton asking to work the Taj instead of her regular Castle gig and promising to charge only $100,000 a show. Joe Piscopo did his Sinatra imitation on the birthday song, followed by a string of Jap gags—oblivious to the presence of several Japanese high rollers in the front rows—even cracking that Atlantic City would be owned by the Japanese if it wasn’t for Donald. A George Bush imitator declared Donald should be President…A chorus line in skintight outfits gyrated around chairs singing longingly about Donald’s dollars. Then Andrew Dice Clay appeared on another giant screen to thank Donald for the Taj hookers, saying they had stamps on their asses to show they’d had their shots.

Sadly, Barrett couldn’t attend the event. He was arrested on his third attempt to get into the ballroom and cover the party. But his research assistant managed to enter the ballroom and cover the festivities.

Antarctica is melting and shows no sign of slowing down

Antarctica is melting and shows no sign of slowing down

By on Jun 3, 2016

Cross-posted from

Climate CentralShare

Over the past few years, the evidence has piled up that glaciers in parts of Antarctica have been melting and retreating at an increasingly worrying — and potentially unstoppable — pace.

Now, new research shows that glaciers in a region of West Antarctica that has received relatively little attention to date have lost a considerable amount of ice. And that ice melt and retreat has been going on for decades, longer than previously thought.

The Bellingshausen Coast in West Antarctica.Robert Bingham

The findings, detailed in the journal Geophysical Research Letters, have implications for understanding the potential sea-level rise that the vast icy expanse of Antarctica could unleash as the Earth’s temperature continues to rise.

“I think this study just underscores that West Antarctica, in general, is not only exceptionally vulnerable to retreat triggered by ocean melting at the coastline, but that it is happening now and it is showing no sign of slowing down,” study coauthor Robert Bingham of the University of Edinburgh said in an email. “This whole process is pretty pervasive.”

West Antarctica ice loss

Since satellites first began looking down on Antarctica in the 1990s, polar scientists have noticed rapid changes in the ice of West Antarctica, particularly along its coastlines. It is here that the massive glaciers — essentially rivers of ice — that flow from the continent’s interior meet the sea and the ice begins to float.

The floating sections, known as ice shelves, help regulate the flow of the glaciers behind them. As those ice shelves shrink or collapse, the flow of the glaciers speeds up, increasing the amount of previously land-bound ice that is added to the world’s oceans, like ice cubes to a glass of water.

Warm ocean water is circulating under these ice shelves, eating away at them and causing them to thin, as well as pushing back the grounding line, or the point where land-bound ice begins to float. As the grounding line retreats, it exposes thicker and thicker portions of the glacier, increasing its flow.

Several major ice shelves have collapsed in the last two decades, and the speeds of several crucial glaciers, such as Pine Island Glacier, have accelerated. Recent studies suggest some have even reached a point of no return.

All told, the West Antarctic Ice Sheet contains enough ice to add 10 to 13 feet to global sea-level rise were it all to melt; even an incomplete melt would imperil low-lying coastal areas around the planet. One sector, the Amundsen Sea Embayment, contains several of the most worrisome glaciers. It alone currently accounts for about 10 percent of sea-level rise.

But close behind it is a neighboring area, called the Bellingshausen Sea or the South Antarctica Peninsula. It accounts for about one-third of the ice loss from the entire West Antarctic Ice Sheet (the Amundsen accounts for nearly half), and a study last year showed its glaciers have sped up considerably since 2009. But it has been relatively little studied, especially compared to the more attention-grabbing parts of the Amundsen.

Unmonitored melt

During a 2009-2010 field mission, Bingham looked to shed more light on the region by scanning the ground below one of the fastest-moving Bellingshausen glaciers, the Ferrigno Ice Stream. He found a huge canyon underneath that is likely funneling warm ocean water under the ice.

“This only served to highlight to me that there is so much about the Bellingshausen Sea sector of West Antarctica that has gone unmonitored while most of the world’s eyes (glaciologically speaking) were looking beyond to Pine Island Glacier,” Bingham said.

To get a better picture of the overall ice loss in the area, Bingham and his Ph.D. student, Frazer Christie, analyzed hundreds of satellite images of the area going back to 1975 and tracked the position of the grounding line along 1,240 miles of coast.

They found that 65 percent of the coastline had seen grounding line retreat since 1990, while only 7 percent had seen an advance. The total amount of ice lost over the last 40 years is about 390 square miles, an area about the size of Dallas.

The results “show that this whole coastline has been in a state of retreat since records began in the early 1970s,” Bingham said. That contrasts with previous thinking that only certain glaciers, like the Ferrigno Ice Stream, were seeing significant ice loss while the rest were fairly stable.

“The study illustrates that Antarctica is not immune to changes and that some of what we are seeing today started decades ago,” Eric Rignot, a NASA glaciologist who was not involved with the work, said in an email.

One notable oddity was the Venable Ice Shelf, which has thinned, but hasn’t retreated much. The researchers think it is pinned to a ridge on the seafloor that is keeping it stable for now. Scientists think the same was true of Pine Island Glacier — for a while.

Exactly what the pervasive ice loss in the Bellingshausen Sea area means for future global sea-level rise isn’t entirely clear, in part because of the paucity of data from the area. Bingham says that researchers need a better idea of the topography underlying the ice so they can better model how it will change in the future.

“The Bellingshausen Sea region of West Antarctica stands as one of the least surveyed regions of ice and ocean on the planet,” he said.

Also needed is a clearer picture of ocean circulation there and in the entire West Antarctic region.

“The Antarctic Peninsula certainly does not receive as much attention as it should,” Rignot said. “I would recommend more work in this area, which is illustrative of what will happen farther south as climate gets warmer.”

Of all the elements that make up Earth’s atmosphere, nitrogen is by far the most abundant. It is also one of the most inert. Nothing happens when you breathe it in, swallow it, or let it suffuse your skin. Nitrogen gas likes to stay nitrogen gas.

But in the early 20th century, two German chemists, Fritz Haber and Carl Bosch, figured out how to pluck fertilizer from thin air by making ammonia (NH3) out of nitrogen gas (N2). You need energy, lots of it. The Haber-Bosch process relied and still relies on high temperature, high pressure, and hydrogen atoms ripped from fossil fuels. Ammonia from this process fertilizes crops, which in turn nourish you. On average, half the nitrogen in your cells might come from Haber-Bosch. “The Haber-Bosch process is one of the most important for humanity,” says Mercouri Kanatzidis, a chemist at Northwestern University.

But what seemed ingenious a hundred years ago is running into problems in 2016. The Haber-Bosch process burns natural gas (3 percent of the world’s production) and releases loads of carbon (3 percent of the world’s carbon emissions). If relying on fossil fuels to give the world electricity and heat is unsustainable, so is relying on fossil fuels to grow its food.

So interest in a Haber-Bosch alternative is heating up. Last month, the Department of Energy issued a funding opportunity announcement for a sustainable way to make ammonia. The challenge isn’t just making ammonia without fossil fuels—scientists can already do that—but to do it at a scale and price that can compete with an industrial process perfected over a hundred years. And that ultimately might take more than just a technological breakthrough.

Bacteria and Sunlight

Of course, ammonia existed on Earth long before Haber and Bosch came long. For millions of years, nitrogen-fixing bacteria in soil have been taking nitrogen gas from the air and converting it into ammonia, which in turn is taken up by plants, which are eaten by animals, human and non-human. You have nitrogen in your cells from these bacteria, too.

So in the search for new ways to make ammonia, scientists have turned to imitating nature. “Biology does this reaction in fairly simple way compared to Haber-Bosch,” says Paul King, a photobiologist at the National Renewable Energy Laboratory. For one, it happens at room temperature, since any living thing would be cooked and crushed at Haber-Bosch conditions. Nitrogen-fixing bacteria have enzymes that grab N2 molecules and H+ ions, orienting them just the right way so they form ammonia, or NH3.

This reaction does require a jolt of energy. In bacteria, it comes from snapping off a piece of a molecule called ATP. But King has figured out something simpler: sunlight. In a paper recently published in Science, his group made light-sensitive nanorods, similar to what you might find in solar panels, that plug into the enzyme to give it a zap. Basically, all you have to do is mix together this cadmium-based material, some enzymes, and leave it out in the sun. Voila, ammonia—though only a small amount of it.

The problem with making more ammonia? “Enzymes are really cost prohibitive,” says King. Enzymes are incredibly complex molecules that have to be purified from living bacteria. “It makes days and days and lots of water to separate it, and you end up with less than a microgram,” says Kanatzidis. “We cannot even contemplate using that.”

At Northwestern, Kanatzidis is looking for a way to replace the enzyme with a man-made material called chalcogel. In another recently published paper, his team took metals commonly found in the active sites of enzymes and made clusters of them. The cluster is black, so it also absorbs light energy. When researchers scatter the material into water, shine sunlight on it and bubble nitrogen gas through, they get ammonia. And this time, no expensive enzymes.

It comes at a different cost though. The nitrogen-fixing enzyme has evolved over millions of years to grab N2 and H+; in comparison, the chalcogel is just a crude approximation, and it’s thousands of times slower than the natural process. King’s light-powered system—the one that still uses an enzyme—synthesizes ammonia at about 63 percent of the enzyme’s natural rate. And both are not as easily scaled up to Haber-Bosch levels. Yet other groups have experimented with polymer membranes and titanium-based molecules, though those have durability and efficiency problems, too.

The Ammonia Economy

So these new ammonia synthesis systems have a long way to go, but they don’t necessarily have to beat Haber-Bosch. It’s no coincidence that King and Kanatzidis have converged on using sunlight to power ammonia synthesis. Making fertilizer via Haber-Bosch is like making electricity at a big central coal-fired power plant—electricity that then needs to be transported hundreds of miles to its point of use.

But with solar panels, electricity can be made where it’s used. With solar-powered ammonia synthesis, so can fertilizer. And while electricity storage is tricky, storing ammonia is easy by comparison. You might imagine other systems of ammonia synthesis that rely on yet other forms of renewable energy. “I can’t tell you how many times we’ve talked to people who want to take the output of their wind turbine and make their own fertilizer or fuel for the farm,” says John Holbrook, executive director of the NH3 Fuel Association.

As the name implies, Holbrook’s ambitions for ammonia go beyond fertilizer. Today, cars and power plants run on fossil fuels, whose energy is stored in carbon bonds. But plenty of energy is stored in ammonia, too, and you could imagine a fuel economy based on nitrogen. (After all, the other major use of ammonia from the Haber-Bosch process in early 20th century Germany was making explosives.) The upside, though, is no more carbon emissions. “We in the ammonia fuel community feel like we’ve cracked a code in terms of getting recognition,” says Holbrook. “We’ve been at it for 13 years without anyone from the Department of Energy attending our conference.” This year’s featured speaker at the NH3 Fuel Association conference will be Grigorii Soloveichik, a program director at the DOE.

Funding interest from the top levels of government is one thing. Making fossil fuel-free ammonia synthesis commercially viable is another. King thinks what will ultimately set the industry off is a carbon tax. Humanity doesn’t need to recognize value in nitrogen; it needs to see danger in carbon.
