    What if the solution to the retail industry's $890 billion returns crisis wasn't better logistics, but better logic? Disney Petit, founder and CEO of Liquidonate, is proving that the most sustainable return skips the trip back to a warehouse and goes directly to a community in need. Americans returned nearly 17% of all retail purchases last year, generating 2.6 million tons of landfill waste and 16 million tons of CO2 emissions. Each return costs retailers between $25 and $35 to process, yet 52% of consumers admit to participating in return fraud at least once. Petit witnessed this broken system firsthand as employee number 15 at Postmates, where she built the customer service team and created Civic Labs, the company's social responsibility arm. Her food security product Bento, which allowed people without smartphones to access free food via text message, won Time Magazine's 2021 Invention of the Year Award. Now Liquidonate has earned recognition as one of Time's Best Inventions of 2025.

    Liquidonate integrates directly with retailers' existing warehouse and return management systems. When a product comes back and can't be resold—open box, slightly damaged, or simply unwanted—the platform automatically matches it with a local nonprofit or school that needs it. "It's the same reverse logistics workflow they already use," Petit explains. "It's just redirected toward community good instead of going to the landfill." The platform handles everything: shipping labels, pickup coordination, and tax documentation so retailers can write off donations. Retailers recover logistics costs through tax benefits while communities receive quality products, and millions of pounds of goods stay out of landfills.

    To date, retailers using Liquidonate have diverted over 12 million items from landfills, working with more than 4,000 nonprofits across the country. Liquidonate also tackles return fraud by eliminating "keep it" returns, when customers claim they want to return something but are told to keep the item and still receive a refund. "One hundred percent of the time we're producing a shipping label for a nonprofit who wants that product," Petit says. "We completely eliminate that keep-it return option, so we eliminate the returns fraud option." With $900 billion worth of inventory potentially available for redirection, Petit approaches the business through the lens of environmental justice, building a for-profit company designed to prove that doing good and doing well aren't mutually exclusive—they're interdependent.

  • Luke Purdy, Wieden+Kennedy's Director of Sustainability, on Advertising's Power To Change
    Nov 10 2025
    Can the industry that taught the world to consume help us learn to consume more responsibly? Luke Purdy, Director of Sustainability at one of the world's leading creative agencies Wieden+Kennedy, is betting his career on it. After 13 years working on major accounts like Nike and Corona at one of the world's most influential creative agencies, Purdy did something unusual: he wrote his own job description and asked to become the agency's first sustainability director. Wieden+Kennedy gave him the job, and in 2023, the agency became the first global advertising network to achieve B Corp certification across all nine offices in seven countries. With brands spending over $700 billion annually on advertising worldwide, the messages agencies craft shape not just what people buy, but how they think about consumption itself.

    Luke discusses how he sold sustainability as a business value proposition rather than a compliance issue, why he reports to the CFO instead of the CMO, and how Wieden+Kennedy's carbon removal program for video productions is changing industry standards. He also tackles thorny questions about greenwashing that can guide which clients agencies should work with, arguing that guiding any company toward sustainability is better than refusing to engage.

    He shares lessons from helping transform Danish Oil and Natural Gas into Ørsted, one of the world's leading renewable energy companies, and explains why authentic storytelling beats green leaves and clichés every time. Can advertising agencies avoid greenwashing while still growing their clients' businesses? And what does it mean when sustainability becomes culture rather than just compliance?You can learn more about Wieden+Kennedy's sustainability work at wk.com.

  • Terraformation CEO Yishan Wong On Reforesting 3 Billion Acres
    Nov 3 2025
    Most Silicon Valley CEOs who cash out their stock options start another tech company. Yishan Wong planted trees instead. After helping build PayPal, Facebook, and serving as Reddit's CEO, Wong concluded that humanity's biggest challenge wouldn't be solved with algorithms or network effects—it would be solved by restoring the planet's forests at an unprecedented scale. Mitch Ratcliffe sits down with Wong to discuss Terraformation, the company he founded in 2020 with an audacious mission: restore 3 billion acres of native forest worldwide—an area larger than the entire United States.

    Planting a trillion trees isn't just about seeds in the ground. It's about solving bottlenecks like funding gaps that leave 95% of qualified forestry teams without resources, seed shortages, lack of infrastructure and technology, gaps in tracking and verification. Terraformation built a support system that includes modular seed banks, solar-powered nurseries, open source forest management software, which is called Terraware and a seed to carbon forest accelerator that's modeled on tech startup accelerators. Since founding Terraformation, Wong has enabled the planting of over 4.7 million trees across 394 species, established 19 seed banks and 21 nurseries and created more than 798 jobs.

    "We made Terraware not because this is the most genius piece of technology that will change the world," Yishan explains. "We said, hey, let's just help forestry teams achieve certain basic necessary activities." Unlike commercial timber plantations that prioritize fast-growing monocultures, Terraformation focuses on biodiverse native forests. Native tree species can support an order of magnitude more life than non-native species because they've co-evolved over millions of years. "Trees are the anchor species for a forest ecosystem," he added. "What you're doing is you're growing trees as the anchor species so that all of the other life in that forest ecosystem comes back."

    Terraformation recently won the Keeling Curve Prize and the G20's RestorLife Award. The company also received recognition at the Global Sustainability Awards, winning SME Company of the Year. Yishan explains why a former Reddit CEO believes in low tech solutions that are the right approach to climate change, how Silicon Valley's lessons about scaling systems could apply to reforestation and what it takes to build an organization designed to be replicated rather than defended.

  • The Climate Action Network's Pre-COP30 Briefing with Rebecca Thissen
    Oct 27 2025
    Ten years after the Paris Agreement, the world's climate negotiators will gather in Belém, Brazil this November for COP 30, a summit many are calling a critical juncture for global climate action. After COP 29 in Baku ended with what developing nations called a woefully inadequate $300 billion annual commitment—far short of the $1.3 trillion economists say is needed—can multilateral climate negotiations still deliver the justice and transformation the climate crisis demands? And with 71% of climate finance currently provided as loans rather than grants, how is the debt crisis crushing developing countries' ability to invest in climate action?

    Rebecca Thissen, Global Advocacy Leader for Climate Action Network International, joins Sustainability In Your Ear to unpack what's really at stake in Belém. With a background in International Public Law and years in the trenches of climate justice advocacy, Thissen works at the intersection of finance, economics, and climate action to ensure money flows where it's needed most. She discusses the just transition work program, Brazil's controversial Tropical Forests Forever Facility, the International Court of Justice's groundbreaking ruling on climate obligations, and why only 10% of countries showed up with their nationally determined contributions. Climate Action Network represents nearly 2,000 organizations across 130 countries, making it the world's largest coalition working on climate change. You can follow their daily updates during COP 30 through their newsletter ECO at climatenetwork.org.

  • Buckstop's Alexander Olesen Digs Into Urban Mining
    Oct 20 2025
    Every solar array, battery system, and EV charger installed over the past decade will eventually need to be decommissioned. Yet there's no unifying system to handle that flow of materials—no operating system for the reverse supply chain that the circular economy depends on. While Americans recycle 97% of vehicles, we recycle less than 20% of electronics, leaving valuable critical minerals like lithium, cobalt, and gold to languish in warehouses or end up in landfills. The electronics embedded in our built environment represent the richest mining scene on Earth, yet we treat these refined materials as waste rather than the valuable resources they are. Meet Alexander Olesen, co-founder and CEO of Buckstop, an urban mining company launched in early 2025 to build what he calls "the intelligence layer for the circular economy." He previously founded Babylon Micro Farms, which develops distributed vertical farming systems, and he returns to Sustainability In Your Ear to share his new mission: creating a sustainable end-of-use solution for every electronic device on Earth.

    Buckstop took just three months to deploy its "algorithmic assay," a method of deconstructing finished goods into their raw materials and critical minerals at scale, something that wasn't possible to do efficiently before the advent of AI. The result: asset owners can now see the granular value of their deployed electronics in unprecedented detail. The scrap value of electronics typically yields only 1-5% recovery, but resale value can reach 20-30%. For Fortune 500 companies with billions in fixed assets, that circularity delta represents enormous value currently being destroyed.

    Olesen's approach draws directly from his decade-long experience as an OEM manufacturing vertical farming equipment with 1,200 unique components. "Why is there no comprehensive end-of-life solution for technology assets?" he asked. Every hardware entrepreneur he knew in renewables, robotics, and distributed systems faced the same problem.

    Buckstop's model draws inspiration from an unlikely source: Kelley Blue Book. "Kelley Blue Book was the data stream that formalized the aftermarket for vehicles," Olesen notes. Before that standardization, people would leave cars rusting by the roadside. Today, the automotive industry is the most circular industry on the planet. Olesen believes the same transformation is possible for the electronics industry. The platform currently focuses on renewable energy infrastructure—solar panels, batteries, inverters—but Buckstop's long-term vision extends to one day tracking all electronic assets. As Olesen puts it: "If you can't measure it, you can't improve it." That measurement is where circularity begins.

  • Sustainability In Your Ear: Culligan CEO Scott Clawson Maps The Future Of Water
    Oct 6 2025
    Read a transcript of this episode. Subscribe to receive transcripts.

    Turn on any faucet in America, and chances are the water meets federal safety standards. Yet Americans buy 50 billion single-use plastic water bottles annually—enough to circle the Earth 200 times if laid end to end. The bottles take 450 years to decompose, and recent research found that a single liter of bottled water can shed up to 240,000 pieces of microplastic that we ultimately consume. Meanwhile, 37% of global drinking water remains contaminated, with PFAS "forever chemicals" and lead appearing even in neighboring homes on the same street. Meet Scott Clawson, Chairman and CEO of Culligan International, the nearly 90-year-old company that's become the global leader in water services by making filtered water more accessible than single-use plastic. Under Clawson's leadership, Culligan serves 170 million people worldwide, and the company's filtration systems have helped avoid the use of 45 billion plastic bottles annually.

    The company has set ambitious targets: achieving net positive water impact by 2050 and cutting scope one and two emissions intensity by 40% before 2035. After completing WAVE water stewardship verification, Culligan discovered that even testing filtration equipment was wasteful, leading the company to develop dry-testing methods that eliminate water waste before machines reach consumers. The company has electrified 25% of its fleet and donated 9 million liters of water to communities in need in 2024 alone. Clawson's approach to sustainability isn't just operational—it's personal.

    A decade ago, while vacationing in the Bahamas, he encountered a beach covered in plastic waste. "That's when my inner balance was sparked to make sure we do more than just use our planet to make money, but let's use our planet to help it be a better place to live," he recalls. As water scarcity intensifies globally, Clawson believes the consumer holds the power: "Every time you pick something up off the shelf, you are voting. You're sending a signal to a company." His message is clear—test your water, understand what's in it, and invest in point-of-use filtration rather than contributing to the plastic crisis.You can learn more about Culligan International at culliganinternational.com.

  • Terracycle Founder Tom Szaky On Building A Service-Centered Circular Economy
    Sep 29 2025
    Read a transcript of this episode. Subscribe to receive transcripts.For decades, our relationship with waste has been defined by disposability and denial. The disposability of everything from coffee cups and cigarette butts to smartphones, and the denial about where it all goes when we're done with it, means that humans generate over 2 billion tons of waste globally each year, with Americans alone throwing away 290 million tons of waste annually. The convenient fiction is that recycling solves the problem. But the reality is starkly at odds with that comforting idea, and today we explore the challenge with a recycling innovator. Meet Tom Szaky, founder and CEO of TerraCycle, who has spent over 20 years proving that what is considered impossible to recycle is really just unprofitable to recycle—by making the hard-to-recycle profitable. Terracycle has tackled some of the world's most challenging waste streams, like dirty diapers, cigarette butts, chewing gum, and composite packaging that municipal recyclers cannot handle profitably. TerraCycle now operates in over 20 countries.Even as TerraCycle proves that many materials can be recycled with the right economic model, Tom has concluded that recycling alone won't solve waste at its root cause, which led to the launch of the reusable packaging-based consumer good service Loop, which offers reusable packaging at stores in the U.S., Britain, and France. This realization led Tom to the conclusion that the waste crisis isn't just about recycling better, it's about redesigning our consumption. Historically, humans have made a mess. Every archaeological site has found waste piles, or what are called middens, alongside human settlements. However, other social species also pile up waste, as well as their dead, in middens. But we needn't bury ourselves in waste just because humans have always produced trash, as Tom explains, the economics of recycling have limited its success and at a time when we could not track and manage materials, such as during the explosion of trash during the consumer revolution of the 1950s we didn't have the logistical technology to address the many different materials in our garbage cans, but now we do from scannable codes to optical scanners that sort materials on high speed conveyor belts at materials recovery facilities (MRFs). Terracycle's pricing today reflects the cost of recycling a material when collection and sorting services, along with localized processing capacity, are not widespread. Now's the time to take that step towards circularity, a process that needs to start with companies that make what we buy. Tom shares his belief that the most powerful influence is each person's decisions at the store, which sends a vote to companies; you can send a message by opting for recyclable and reusable packaging.

  • Sustainability In Your Ear: Heather Terry's Regenerative Journey At GOODSam Foods
    Sep 22 2025
    The global food system stands at a crossroads. Climate change is reshaping where crops can grow, trade disputes threaten supply chains, and smallholder farmers who produce much of our food often have the least power in the system. Meet Heather Terry, founder and CEO of GoodSAM Foods, and discover how the company is transforming the traditional smallhold farm model by putting people and regenerative agriculture at the heart of a growing food company. GoodSAM Foods sources 90% of its ingredients directly from smallholder farms in Latin America and Africa, eliminating middlemen and reinvesting profits into farming communities. Terry's approach is both principled and pragmatic: as climate volatility reduces crop yields globally, the companies that have built genuine relationships with farmers will have access to limited harvests. "When I'm a farmer and I suddenly have leverage, who am I going to sell that product to?" Terry asks. "It's relationships."[

    Terry's journey to raise $9 million in Series A funding over 18 months illustrates the disconnect between traditional investors and regenerative business models. After facing skepticism from conventional CPG investors, she found success with impact investors who understood that sustainable food systems represent the future of the industry. While GoodSAM maintains USDA Organic and Non-GMO Project verification, Terry takes a critical stance on regenerative certification labels, arguing that current systems impose Global North standards on farmers who have practiced regenerative techniques for generations. Instead, GoodSAM focuses on direct relationships and on-ground verification. Her proactive approach protected both the company and its farming partners from sudden economic shocks at a time when the U.S. food system faces mounting pressures from climate impacts and trade policy changes. "Every time you pick something up off the shelf, you are voting," Terry said. "You're sending a signal to a company."
