Sustainability: Fact or Fiction?

If asked could you provide proof that your company’s sustainability efforts are more than just greenwashing? Does your company utilize science, data and facts to drive sustainability solutions over clever marketing or “feel good” stories about sustainability?

The recent Earth Day has caused me to reflect a bit about what is actually being done to improve the environmental condition of the planet.  I watched the self-promotion of companies trying to grab our attention and sell us on how sustainable and environmental they are.  There seems to be a great deal of focus from companies to look at sustainability from a marketing standpoint over what should be truly sustainable or at the least better for the environment.  They promote and make claims about some story or process they have implemented and claim it to be more sustainable.  Unfortunately, nearly all of these companies lack the one critical component of sustainability and that is using science, data and facts to drive their solutions.  It seems to me that many companies, including the big fortune 500 would have the ability and resources to hire the right people to oversee their sustainability efforts and implement solutions which are fact and data driven.  Instead what is observed are companies struggling to truly understand what sustainability is about and end up implementing “feel good” or story based gimmicks to promote how sustainable they are becoming when in truth when analyzing the LCA data of these gimmicks most of these “feel good” approaches offer no environmental value or benefit at all.  Do sales and marketing really have that strong of an influence over sustainability efforts which should be driven by science, facts and data?   

What’s worse is when “experts” are used to push the “the only solution to plastic pollution is producing less plastic,” or “we are going to recycle our way out of this problem” agenda.  It is quite unfortunate when these so called experts thoughtless and meaningless opinions are used to steer solutions to this massive problem of plastic pollution.  I know of a couple of industries who are so fixated on the recycling message that the facts and data completely elude any rational thought.  Anyone who understands global population and economic growth would know that producing less plastics is not in our near future and will most likely never happen without a catastrophic reduction to the human species.  The planet is on a steadily increasing rate of growth which leads to more consumption and with that consumption comes the economic development of poorer nations which leads to accelerated consumption.  It’s a nasty circle driven by the growth of the global population and the desire to live a more consumption based life (the good life).  Regardless of whether we use plastic, paper, mushrooms, algae, space dust, or unicorn farts as our packaging materials we will always need a CRAP ton of it and will need to figure out effective, beneficial (to the environment and economy) and valuable ways of handling it.  Gathering and shipping waste to other parts of the country or other countries in our globe to process isn’t the solution, nor is merely suggesting to the public to reduce plastic use. 

If it’s not plastic it will be some other material we are trying to solve the pollution problem for.  So easily we forget the crisis of the past.  To solve the issue of paper grocery bags (which by the way was going to be the end of all the trees and human life as we knew it) we developed plastic bags which is now the new crisis and surprise! It’s also being promoted as the next cause to the end of the human race.  When will the “experts,” “get it” the problem isn’t what material is being used or how much material we use, it’s what we do with and how we handle that material after use!  This is always going to be the problem of a growing population.  We could always go back to the days of using animal stomachs for transporting liquids but that’s a whole lot of animal stomachs and what would the vegetarians use?  Companies must use packaging materials which are more intelligently designed to work within the infrastructures of our disposal environments to create a value and benefit (both environmentally and economically).     

One such approach is in the conversion of plastic waste in the landfill into clean and inexpensive energy.  This approach requires no special or additional handling of materials and converts plastics into biogas through the natural process of microbes.  It utilizes the existing waste management infrastructures while placing the solution on materials to add value within the common disposal environment of a landfill.  If all plastics were designed to work within their common disposal environment by the year 2030 (11 years) landfill gas into energy would be the single largest source of renewable energy and would surpass all other forms of renewable energy including; wind, solar, and hydro.  Let’s stop the BS hyperbole that landfills are these evil and bad places or that the world is running out of landfill space.  The data and the science show the environmental value and benefit of having materials convert into fuel and energy within the landfill. 

Let’s stop pretending ideas like recycling and reduction are going to solve anything.  Those two words have been used as part of the “Reduce, Recycle, Reuse” campaign since the 1970’s.  After nearly fifty years of that campaign look at the mess of where things are today.  The recycling mess we have today certainly isn’t due to a lack of spending money or repeating the message to brain wash everyone into reducing, reusing, or recycling.  It’s due to the fact that words don’t solve complex plastic pollution problems, it also shows that money doesn’t solve these problems either.  Billions of dollars have been given by governments to subsidized the recycling industry to build and support it and what do we have to show for that investment?  Why is the recycling industry in such a mess given all the money and investment that has been provided and why are we ok with knowing that our recycling efforts have resulted in more plastic pollution to our oceans and planet than any other activity?    

Plastics and other waste should work within their common disposal environments to have an environmental value and benefit at disposal.  I know we all “feel good” about placing things in the “recycle bin” and we don’t want to know about the ugly monster of what truly goes on behind the recycle bin “curtain”.  Our recycling efforts have resulted in massive amounts of plastics being dumped oceans and recycling rates in the single digits, so we can “feel good” about ourselves .  It’s time we stop with the “feel good” approach and start taking action to fix the plastic pollution problem using real science, facts, and data driven solutions.  Implementing solutions with the true meaning of circularity and sustainability would benefit society and the environment much more than this baseless approach of double down and continue pushing plastic recycling programs which have failed to provide environmental value (have severely polluted the planet), requires billions to subsidize and has little science and data to support that it actually has environmental value.  Plastics should be designed to go away (to create environmental value) where plastics are thrown away.  If one of those options should include recycling, then the science and data should support the way the infrastructures of collection, sortation, processing, and transportation are implemented in such a way that has environmental (human health is part of this) and economic value.

Should your company be one the many which has implemented a “sustainability” program or process with no data or science to back up the environmental claims you are engaging in nothing more than greenwashing and misleading consumers in the worse possible way.  Whether your company reduces packaging, utilizes recycled content, switched to a more environmental material, implemented a bring-back recycling program, or any of many other gimmicks make sure you have the science and data to back up your claims.  And I’m not talking about manipulating data to fit your program, I’m talking about letting the data drive and create your programs.  9 times out of 10 you’ll find that the data will show that your brilliant idea to implement a bring-back program or a shoe recycling program offers zero environmental value or benefit and in many cases will have a negative environmental impact requiring more resources and producing more carbon than your program thinks it is helping by figuring out how to reuse a material.  The act of reusing/recycling a material/s is not inherently more environmental, it is only more environmental when it the data shows the processes involved to reuse/recycle those materials has a net environmental benefit/value. 

In the end, your company’s sustainability solutions should be all about the environment; shouldn’t it? 

A Look at the Largest Landfill Gas-To-Energy Project in Georgia

The three new plants, combined with Republic’s Hickory Ridge landfill operation, establish Republic and Mas Energy’s landfill gas-to-energy portfolio as the largest in Georgia.

Republic Services Inc. recently unveiled a new renewable energy project with partner Mas Energy LLC that will serve the Metro Atlanta area, generating 24.1 megawatts of electricity, or enough renewable energy to power 15,665 households.

“The energy will be supplied to Georgia Power for distribution throughout the local electric grid. In all likelihood, Georgia Power’s retail electric customers in Metro Atlanta will utilize the energy,” says Michael Hall, principal and chief development officer for Mas Energy based in Ponte Vedra Beach, Fla.

Their agreement, which also includes partners Georgia Power, I Squared Capital, Crowder Construction Company and Nixon Energy, is for 20 years and will convert methane captured from three local landfills at gas-to-energy facilities in the cities of Buford, Griffin and Winder. Those landfills combined have an approximate daily volume of 7,000 tons.

The three plants, combined with Republic’s Hickory Ridge landfill operation, establish Republic and Mas Energy’s landfill gas-to-energy portfolio as the largest in Georgia,” says Michael Meuse, general manager for Republic Services in Atlanta, Ga.

Landfill gas-to-energy projects like these involve capturing methane, a byproduct of the normal decomposition of waste, from the subsurface and routing the methane to a series of engines. These engines convert the methane into electricity, which can be distributed to the local power grid.

“Methane is a greenhouse gas that is naturally produced as organic waste breaks down anaerobically in landfills,” says Meuse. “Methane gas is recovered by the gas collection systems. Gas wells are driven into the waste mass and powerful blowers are used to create a vacuum to draw out and pipe the gas to the energy plant.”

The system then converts the methane gas into a clean-burning fuel.

“The power generation facility utilizes internal combustion engines fueled by the collected and treated landfill gas to produce electricity, which is then delivered to Georgia Power’s transmission and distribution system,” says Hall.

The partnership was fueled by Georgia embracing renewable and clean energy projects within state lines.

“In 2006, Georgia’s Public Service Commission established the ‘QF Proxy Unit Methodology’, whereby qualifying facilities in the state of Georgia were eligible to enter into power purchase agreements (PPA) with Georgia Power that recognized the full value of renewable and clean energy to Georgia consumers,” says Hall. “Mas Energy secured its PPA in early 2014 and brought Republic Services a proposal to build plants at Republic’s Atlanta sites.”

Republic and Mas Energy had previously collaborated on a project at Republic’s now-closed Hickory Ridge landfill site.

“Based on that positive experience, the agreements were made between Mas Energy and Republic Services to develop the (recently announced) projects,” says Hall.

Meuse says that according to the U.S. Environmental Protection Agency (EPA) calculations, energy produced from landfill gas-to-energy facilities will offset the equivalent of: carbon dioxide (CO2) emissions from 127,795,779 gallons of gasoline; carbon sequestered by 930,919 acres of U.S. forests; and carbon dioxide (CO2) emissions from 6,090 railcars’ worth of coal burned.

“Projects such as these reduce reliance on non-renewable resources (coal and natural gas), reduce methane emissions from the site, and eliminate emissions from flares previously used for gas destruction,” he says.

When Should You Not Recycle?

By Robert Coolman

Reduce, reuse, recycle—but for environmentalists, that’s not always a good idea.

When is it right to recycle? If your answer is “always,” I plead with you to re-evaluate your priorities as an environmentalist. We certainly have an obligation to use Earth’s resources and manage waste responsibly, but I believe the priorities and practices of modern environmentalism are in serious need of introspection.

Films like “Wall-E” and “Idiocracy” would have you believe that we are only years away from skyscrapers of garbage on the outskirts of our cities, but the truth is landfill capacity isn’t a problem in the foreseeable future. According to a letter in Nature Climate Change, U.S. landfills have an average of 34 years of capacity remaining, though capacity is growing at a rate of 2.7 years annually. Also, it’s not as if that land is unusable once it’s filled. Much of NYC is built on top of garbage, and so are many parks. Local governments are typically upfront about what places were formerly landfills (here’s mine) and continually monitor methane gas and liquid leachate levels, concerns that modern landfills are specifically engineered to manage.

To say that landfill space isn’t a problem in the foreseeable future isn’t to say we shouldn’t think about it at all. Rather, there are concerns that will cause much larger problems much, much sooner. Because we are already seeing the effects of climate change due to the increase in greenhouse gases, the right time to recycle is when it reduces greenhouse gas emissions. If landfills can be used to reduce greenhouse gas emissions, we should absolutely use them.

Recycling the hard-to-find elements put in many electronics is a no-brainer. Energy, pollution, and money are also all saved when comparing the reprocessing of post-consumer metal scrap against mining and processing ore. As for other stuff? With one major exception, it should all be landfilled.

A common criticism of landfills is how long it takes materials to break down. Ironically, this is backwards; it’s the materials that break down fastest that we should be most concerned about. When organic materials like food, yard waste, and biodegradable plastics break down in a landfill, they anaerobically decompose to produce methane. This is a problem because methane is more than 20 times potent as a greenhouse gas than carbon dioxide, which is what organic matter turns into when it composes aerobically in a composter.

There’s two ways to solve this methane problem. First is to capture the methane produced from a landfill and burn it. This turns the methane into carbon dioxide and can generate electricity. While this is the traditional method, it only works after a landfill has been capped. According to Waste Consultant and Yale Student Jon Powell, “91 percent of all landfill methane emissions are due to landfills that are still open.” Additionally, the infrastructure to produce electricity from combusting methane is subject to a cost/benefit analysis of how much methane is produced and for how long.

The alternative is to separate out organic matter from other landfilled solids, then intentionally turn it into methane which can be turned into electricity at an even greater return. Because the carbon contained in biomass (and by extension the carbon in the gases that evolve from it) was brought out of the atmosphere by plants performing photosynthesis on atmospheric carbon dioxide, returning bio-based carbon to the atmosphere (specifically in the form of carbon dioxide) does not contribute to the total amount of atmospheric carbon, and thus does not contribute to climate change.

So now we’re up to four bins: electronics, metal, biodegradable stuff (including most paper), and everything else. The “everything else” bin goes directly to the landfill, and includes both plastic and glass. Recycling glass is so close to a borderline energy improvement that it probably doesn’t deserve its own bin. As for plastic, anything that’s not code 1 (rPET) can’t be recycled to make containers and is instead demoted to plastic lumber, etc. When it’s done being that, it’s almost certainly going to the landfill anyway.

Why not incinerate used plastics to produce energy? The atoms in plastic come from petroleum, so burning plastic still counts as a fossil fuel and creates a net increase greenhouse gases. In a landfill, the carbon in plastic is said to be “sequestered” which is the end goal of taking carbon out of the air and storing it so it won’t reach the atmosphere. Methods of sequestering atmospheric carbon are still under development and inherently take lots of energy; more energy than we got from burning the plastic in the first place. Instead of (1) burning plastic (2) taking the released carbon out of the air at great energy cost and (3) sequestering it, it’s probably best just to leave it sitting in a landfill.

This was a great article and shows that the author has a pretty good understanding of the realities of recycling. In my time I have run across a handful of people that are misguided in their belief that we should recycle everything. When you hear someone say this you can rest assured that the person making that statement lacks the understanding and knowledge about the realities of recycling. And unfortunately, many people mistakenly quote countries out of the EU as recycling rates as high as 80%. Many of these countries include incineration in their recycling numbers.

Unfortunately those that may think we should recycle everything throw out inaccurate and misleading recycling rates out into the public domain to get others to believe the same misguided and environmentally and economically detrimental approach to our waste. In the meantime, there are companies like ENSO Plastics who understand the realities of our waste infrastructures and is working diligently to develop solutions that will make the most environmental impact today.
