    Earth911 Podcast: Author Nadina Galle on The Nature of Our Cities
    Sep 16 2024
    More than half the world's population—4.4 billion people—live in cities today. That number is expected to rise to 80% by 2050. Our guest, Nadina Galle, is a trailblazing ecological engineer and author of The Nature of Our Cities. She is an ecological engineer who studies the intersection of nature and technology in urban environments. Nadina developed the concept of an Internet of Nature (IoN) that uses tools like artificial intelligence, automation, and sensors to support and enhance ecosystems within cities. Nadina's book offers a transformative perspective on how urban spaces can be reimagined in the face of climate change and sprawling development. She shares the inspiring story of the Groene Loper project in Maastricht, Netherlands, where soil sensors were deployed to monitor tree health. The results were remarkable, with trees supported by this technology growing up to three times larger than those without it. This is a powerful example of how technology can not only protect trees but also transform urban spaces into healthier, greener environments.

    From fire and the wheel to the reinforced concrete frames that define modern buildings, we are surrounded by technology. We tend to forget that technology emerged in response to nature — too often, we treated nature as the enemy, the chaos to be contained instead of recognizing that nature’s cycles and changes are the harmony we need to join to sustain society. The loss of any semblance of natural patterns, which ultimately leads to the depletion of the resources necessary for life, has inevitably led to the collapse of previous major civilizations. Modern society has more runway than previous societies because we have created a global economy, but that risks an even greater fall for our species when the ecological underpinnings of our prosperity collapse. The Nature of Our Cities is a powerful, straightforward, and emotionally resonant book to help you think through your role and choices in the restoration of nature. You can find it on Amazon or Powell's Books.

  • Earth911 Podcast: Cemvita’s Biotech Breakthroughs

    Earth911 Podcast: Cemvita’s Biotech Breakthroughs
    Sep 9 2024
    The global push for sustainability has reached a critical juncture, particularly in industries traditionally associated with high environmental impacts, such as chemical manufacturing and mining. These sectors, vital to the global economy, are also significant contributors to carbon emissions and environmental degradation. However, innovative approaches are beginning to transform how these industries operate, making sustainability not just an option but a driving force of innovation. On today's show, you'll meet and hear Tara Karimi, co-founder and Chief Scientific Officer of Cemvita. Tara and her brother, Moji, bring unique backgrounds -- Moji in petroleum engineering and she in biochemistry -- to the challenge of converting CO2 into the raw materials, known as feedstocks, for new chemicals, materials, and food products. They use of synthetic biology to turn a greenhouse gas into a useful resource. Cemvita’s breakthrough is just one of many CO2 capture and conversion strategies that could drastically reduce the carbon footprint of industries that are often criticized for their environmental impact.

    Cemvita applies biomimicry, the science of learning how nature acts to produce the cornucopia of life-supporting materials. The idea emerged in the early 1980s and now, 40 years later, we’re seeing not just occasional biomimetic innovation but potentially industry-transforming changes in strategy and environmental impact. There's a long way to go before, as Tara explains, we reach a carbon neutral and still prosperous economy. Cemvita’s approach, which combines organic and inorganic chemistry with the insight to see biomimetic alternatives to heat-intensive chemical refineries by, for instance, seeing a depleted oil well as a natural bioreactor to make gold hyrdogen or replacing leaching ponds filled with toxic chemicals with enclosed, non-toxic processing columns, point to just two of the paths out of our planet-killing industrial models.

  • Earth911 Podcast: Rachael Z. Miller Tracks Microfiber Pollution

    Earth911 Podcast: Rachael Z. Miller Tracks Microfiber Pollution
    Sep 2 2024
    Rachael Z. Miller is a leading voice in the fight against microfiber pollution, the plastic smog that trails our clothing like exhaust from a car. You might not see them, but our synthetic clothing sheds millions of tiny plastic fibers that make their way into our atmosphere, oceans, and rivers. It’s been less than a century since the introduction of synthetic textiles — nylon was the first about 90 years ago — but microfibers are already found everywhere on the planet, from the peaks of the Himalayas to the guts and bloodstreams of our bodies and those of mammals and marine life. As the founder of the Rozalia Project for a Clean Ocean, Rachael has dedicated herself to documenting and mitigating the impact of this invisible pollutant, including launching the Cora Ball, a laundry accessory that reduces the microfibers released during a wash.

    Rachael’s work shines a light on how something as simple as washing our clothes can have far-reaching consequences for ecosystems and wildlife, as the story she shared in a recent Earth911 explains: Polar Bears and Penguins Aren’t Wearing Our Clothes But They Might Be Eating Them. She’s also a National Geographic Explorer who has visited the Arctic and Antarctic to study the spread of microfibers. We discuss Rachael’s pioneering efforts to raise awareness, her innovative solutions, and what we can all do to reduce microfiber pollution in our daily lives. Tune in for a conversation that could change how you think about your laundry routine. You can find out more about Rachael and her work at https://www.rozaliaproject.org/

  • Earth911 Podcast: Room & Board Makes Furniture Sustainability A Top Priority

    Earth911 Podcast: Room & Board Makes Furniture Sustainability A Top Priority
    Aug 26 2024
    Meet Emily McGarvey, furniture maker and retailer Room & Board's first Director of Sustainability. The company, founded in 1980, recently became an employee-owned B Corporation. Room & Board has made significant efforts to reduce the environmental impact by engaging 12,000 U.S. craftspeople to make its furniture, achieving 95% sustainable wood sourcing, including using urban wood recovered for reuse in tables and chairs and making 51% of its packaging recyclable on the path to 100% targets in 2025.

    The global furniture industry is expected to see $765 billion in sales this year, according to a Statista analysis, and $133 billion of that in the United States. Reducing the carbon emissions associated with home furnishings — from sourcing wood and materials near producers to shortening supply chains to minimize the need for shipping — can make more sustainable choices available to consumers. For example, the retail chain Ashley Furniture has the seventh largest ocean shipping carbon footprint among major brands because most of its manufacturing is based in Asia. You can learn more about Room & Board at https://www.roomandboard.com/

    Correction: A reference to Room & Board's recyclable packaging progress needed to be corrected. Rather than having achieved 89% recyclable packaging, the company currently uses 51% recyclable material -- its goal is to reach 100% by 2025.

    Earth911 Podcast: USEFULL Founder Alison Cove Brings Reusable Packaging To Campus Cafeterias
    Aug 19 2024
    Alison Cove, CEO and founder of USEFULL, works at the forefront of a critical shift in how we approach food service sustainability. By implementing collection systems for reusable food packaging, USEFULL helps university and corporate cafeterias reduce their reliance on single-use plastics and paper packaging. Alison joins the conversation to explain her company's trackable, tech-enabled reusable steel food containers and cups. After adopting Usefull's reusable system, Carleton College saw a drop in its loss rate from almost 60% to less than 1%. This achievement is part of a broader movement toward creating campus circular food service systems to cut waste and foster a broader culture of sustainability.

    The importance of reusable food service containers cannot be overstated. Single-use plastics contribute significantly to global plastic pollution, particularly in food service. In the U.S. alone, the market for disposable food service containers is vast, with sales reaching approximately $27.81 billion annually. This extensive use of disposables not only adds to the billions of tons of waste generated each year but also exacerbates the environmental impact through the production, disposal, and potential for pollution from these single-use items.

    Earth911 Podcast: Relocalize Aims to Hyper-Localize Ice and Beverage Production
    Jul 22 2024
    Growing, packaging, transporting, and distributing food is a major source of society’s emissions, accounting for approximately 26% of annual global emissions. Reducing the impact of food production is critical to bringing society back within the planetary boundaries, and Wayne McIntyre, cofounder and CEO of Montreal-based Relocalize, wants to “Decarbonize and hyper-localize food & beverage manufacturing.”

    The company is developing technology and a business strategy for decentralized food production using automated microfactories that are placed close to major consumer markets. It promises retailers “full control over their supply chain” in exchange for providing just 1,200 sq. feet of space for Relocalize’s operation. The result, Relocalize claims, will be up to 30% savings on products, 90% less CO2 emissions, and other operational savings because the food does not need to be transported long distances.

  • Earth911 Podcast: Carbon Limit's Tim Sperry Pours the CaptureCrete Story

    Earth911 Podcast: Carbon Limit's Tim Sperry Pours the CaptureCrete Story
    Jul 15 2024
    Tim Sperry is the Founder and CEO of Boca Raton, Florida-based Carbon Limit, the maker of CaptureCrete. He founded the company in 2020 after recognizing concrete’s huge environmental price — it accounts for about 6% of annual global emissions. CaptureCrete is a powder additive for concrete mixes that extracts up to 220 pounds of carbon dioxide from the air per ton, locking it into the concrete as a stable mineral. CaptureCrete’s impact, after accounting for the CO2 it absorbs, is only about 25% of traditional concrete. But this wasn’t Tim's first shot at carbon capture for the built environment. Previously, he developed a paint additive that absorbed CO2 and other pollutants. Carbon Limit was named GreenBiz’s Startup of the Year at Verge 2023.

    Building and operating homes, skyscrapers, factories, and freeways and generates about 10 gigaton of CO2, or about 40% of the emissions associated with energy use on the planet. The ability to tie carbon credits to building and infrastructure projects is key. When you can sell a carbon removal credit for around $200 a ton, the cost of a building can change rapidly. For example, if you’re building a skyscraper that’s 40 stories tall, you might need 4,000 or so cubic meters or concrete, which represents about 5700 tons of the material. With carbon credits that cost $200 per ton, that concrete represents a potential subsidy for the project of $1.1 million dollars. If we’re talking about a mile of freeway, which requires about 17,200 tons of concrete, the credits generated by CaptureCrete’s absorption of CO2 might be worth $3.4 million per mile of roadway. That’s real money, real savings that can make projects reach break-even sooner during the life of the building. You can learn more about CaptureCrete and Carbon Limit at https://www.carbonlimit.com/

  • Earth911 Podcast: Peter Fusaro Takes the Wall Street Green Conference Global

    Earth911 Podcast: Peter Fusaro Takes the Wall Street Green Conference Global
    Jul 8 2024
    For 23 years, Peter Fusaro has been a leading force in the green economy. His exclusive Wall Street Green conference has been a hot ticket for investors and executives looking for sustainable paths forward since 2002. Tis year marks an exciting milestone, as the Wall Street Green Conference will go global with the Wall Street Green Digital Summit on October 15th, 2024. The 12-hour marathon online event will bring together practitioners, investors, and green-thinking startups from around the world through a virtual platform. From Singapore to Saskatchewan, Sydney to Seoul, the summit will showcase groundbreaking products, services, and ideas aimed at helping the planet and the green economy thrive. You can sign up to attend the 24 hour virtual conference for just $25 and hear featured speakers from around the world at https://wallstreetgreendigital.com/

    Energy. Food. Water. Peter explores the foundations of human society, what we work to make available to ourselves and our neighbors so that we can live a peaceful, prosperous life. Each of these essential commodities are seeing rapid, unsettling change and the world order, which was built on burning petroleum, coal, and gas, is already giving way to a new regime of clean, renewable energy. As we measure more human activity, we can create powerful financial incentives to move from wasteful to sustainable, efficient lifestyles and business practices. The question is who will establish the rules of these new markets. That question will not be settled by one government or one industry, because the world is too interconnected and tuned into these issues. There’s a great negotiation underway, led by innovators and policymakers who ultimately answer to every individual citizen when they make a choice at the grocery store, the car dealership, in the voting booth, and at home each and every day. It’s time to learn as much as you can and jump into to the debate. The Wall Street Green Digital Summit global summit will facilitate connections between investors and managers to encourage business success built on sustainable development. Attendees will include venture capitalists, family wealth managers, startups in the green economy, government officials, corporate sustainability officers, and media.

    Earth911 is a Wall Street Green media partner.
