A 'Circular Economy': Why the Next Packaging Will Be Grown, Not Manufactured

We need to design a circular economy where materials are truly, completely recycled.

Infinite economic growth is at odds with our finite planet, and this obsession with endless growth is driving us towards ecological catastrophe. I’ve just returned from the annual World Economic Forum meeting, and this reality has never been so clear to me. The forum brings together economists, but also activists, business leaders, humanitarians and technologists.


As the co-founder of Ecovative, an unorthodox green material science company, I tend to frame our economic and ecological challenges around materials, and the stuff, that makes up everything we use.
Lots of exciting technologies get discussed at the World Economic Forum meeting, but I’ve never heard of a technological method of recycling materials that uses no energy and generates no waste. We live in a world where far less than half of all recyclable materials are actually recycled.
When they are recycled, this process takes a large amount of energy, and generally yields lower and lower grade materials. To borrow a term from Bill McDonough and Michael Braungart’s book Cradle to Cradle, these recycling systems are generally “downcycling”. So, that plastic soda bottle you toss into the recycling bin is likely to be part of a park bench rather than another food grade bottle.
Now, that’s not to say we should give up and stop recycling. It’s still a positive and worthwhile thing to do. But what if we could live in a society where everything—and I mean everything—was recycled using a system that requires no electricity and runs forever?
Rather than pouring decades of human effort into bumping up recycling rates by a few percent through TV ads and education, we need to invent a way to recycle everything, no matter what. Instead of spending millions of dollars developing more energy efficient recycling equipment, we need recycling systems that don’t use any electricity, and don’t even need any machinery whatsoever.
Perfect recycling without any energy or equipment? It sounds impossible, but luckily, we live on a planet where such a system already exists. Some people call it composting, some people call it nutrient cycling; at Ecovative we look at is as “nature’s recycling system”.
In nature, everything is food for something else. Without burning any oil or coal, the molecules in your banana peel might one day soon be part of a tree. Nature’s recycling system gets us very close to a thermodynamically optimized system.
Folks are starting to talk about the circular economy; the Ellen MacArthur foundation just launched a great report on this at Davos. The recycling and upcycling of nutrients in nature in my mind is the gold standard for how we should design our own systems to behave. Either by directly leveraging biotechnology, and making complex products that are compostable, or by mimicking biology in the way we design goods for re-use and re-manufacture.
A steady state economy requires steady state materials.
There is also a continuing discussion about renewable versus non-renewable resources. Ultimately, everything on the planet is renewable; it’s just a matter of time scale. If you want to build with wood, you need 20 up to 250 or more years to grow the trees. Bamboo, just a few months.
If you want to use conventional plastics, you’ll need some very rare environmental conditions and then you’ll have to wait about 65 million years for the petroleum or natural gas to form (or you can take a round-about biological or catalytic route, and get something much more expensive). If you want to use minerals or ores sustainably, you’re talking about a geological time scale anchored in the explosion of stars. It’s clear that the boundary conditions of our planet dictate that eventually we have to focus on using renewable materials to build a sustainable future.
Ecovative is focused on making renewable materials that fit our human time scales. These materials are literally grown by fungi, and can replace plastic foams, particleboard, and more. The materials we grow are “ultra-rapid” renewables; they grow in about a week. Your next purchase might come protected by our packaging. When you’re done with it, you can compost it and return those nutrients to nature.

\n
But I see Ecovative as just one small part of the overall solution. We need thousands of new biological solutions to displace our extreme dependence on synthetic materials borrowed from the bank of time. And for those products we can’t replicate using cellular technology, we must design for re-usability, so that the technical nutrients aren't squandered in landfills or incinerators.
Although we live on a planet with limited physical resources, I’ve come to realize that there are some things that, unlike the misplaced promises of economic growth, actually do compound to grow and grow. Knowledge, ingenuity, creativity and happiness are boundless expressions of the human spirit. Let’s commit to building a future with a circular economy, with steady state materials, so that year after year, far in the distance future, we can continue to enjoy the fantastical creations of the human mind and collective culture.

Christopher Columbus, Alexander Hamilton, William Shakespeare, and Sir Walter Scott are getting company. Statues of the famous men are scattered across Central Park in New York City, along with 19 others. But they'll finally be joined by a few women.

Susan B. Anthony, Elizabeth Cady Stanton, and Sojourner Truth are the subjects of a new statue that will be on display along The Mall, a walkway that runs through the park from 66th to 72nd street. It will be dedicated in August of next year, which is fittingly the 100-year anniversary of the 19th Amendment that granted women the right to vote.

Currently, just 3% of statues in New York City are dedicated to women. Out of 150 statues of historical figures across the city, only five statues are of historical women, including Joan of Arc, Golda Meir, Gertrude Stein, Eleanor Roosevelt, and Harriet Tubman.

It's easy to become calloused to everyday headlines with messages like, "the world is ending" and "everything is going extinct." They're so prevalent, in fact, that the severity of these statements has completely diminished to the point that no one pays them any attention. This environmental negativity (coined "eco-phobia") has led us to believe that all hope is lost for wildlife. But luckily, that isn't the case.

Historically, we have waited until something is near the complete point of collapse, then fought and clawed to bring the species numbers back up. But oftentimes we wait so long that it's too late. Creatures vanish from the Earth altogether. They go extinct. And even though I don't think for a single second that we should downplay the severity of extinction, if we can flip this on its head and show that every once in a while a species we have given up on is actually still out there, hanging on by a thread against all odds, that is a story that deserves to be told. A tragic story of loss becomes one about an animal that deserves a shot at preservation and a message of hope the world deserves to hear.

As a wildlife biologist and tracker who has dedicated his life to the pursuit of animals I believe have been wrongfully deemed extinct, I spend most of my time in super remote corners of the Earth, hoping to find some shred of evidence that these incredible creatures are still out there. And to be frank, I'm pretty damn good at it!

For more than 20 years. Sen. Susan Collins (R-ME) has served the citizens of Maine in the U.S. Senate. For most of that time, she has enjoyed a hard-fought reputation as a moderate Republican who methodically builds bridges and consensus in an era of political polarization. To millions of political observers, she exemplified the best of post-partisan leadership, finding a "third way" through the static of ideological tribalism.

However, all of that has changed since the election of Donald Trump in 2016. Voters in Maine, particularly those who lean left, have run out of patience with Collins and her seeming refusal to stand up to Trump. That frustration peaked with the nomination of Brett Kavanaugh to the Supreme Court.

Wealth inequality has been a hot topic of discussion as of late, but it's something that's occurred all throughout history. Class structure is a complicated issue, especially when you consider that haves and have nots have been in existence for over 4,000 years.

A study published in Science took a look at over 100 late Neolithic and early Bronze Age skeletons found in a burial site in southern Germany. The study "shed light on the complexity of social status, inheritance rules, and mobility during the Bronze Age." Partly by looking at their teeth and the artifacts they were buried with, researchers were able to discover that wealth inequality existed almost 4,000 years ago. "Our results reveal that individual households lasting several generations consisted of a high-status core family and unrelated low-status individuals, a social organization accompanied by patrilocality and female exogamy, and the stability of this system over 700 years," the study said.

Bernie Sanders' presidential campaign looks to be getting a huge big shot in the arm after it's faced some difficulties over the past few weeks.

Alexandria Ocasio-Cortez, a leading voice in the Democratic parties progressive, Democratic Socialist wing, is expected to endorse Sanders' campaign at the "Bernie's Back" rally in Queens, New York this Saturday.

Fellow member of "the Squad," Ilhan Omar, endorsed him on Wednesday.
