Women Leading the Plastic-Free Future: Innovators, Changemakers, and Trailblazers
Plastic Free July isn’t just about skipping straws and bringing your own bags. It’s about system change, and women are at the forefront.
Women around the world are transforming how we design, use, and reuse materials. They’re rejecting the linear “take-make-waste” model and building a regenerative, circular future in its place.
Reclaiming Waste as a Resource
In Kenya, Nzambi Matee, founder of Gjenge Makers, turns discarded plastic into ultra-durable paving bricks that are stronger than concrete. Her team has already diverted more than 20 tons of plastic waste from landfills, creating jobs and building resilient infrastructure along the way.
In North America, Sarah Paiji Yoo, co-founder and CEO of Blueland, is eliminating single-use plastics from everyday cleaning and personal care products through an innovative refillable system. Her solution doesn’t just reduce waste—it reimagines how we design products for reuse, making circularity accessible at scale.
Redesigning the Materials Economy
Julia Marsh
, co-founder and CEO of Sway (USA), is a former packaging designer turned material innovator. Julia saw “plastic waste as a design flaw” and founded Sway to harness seaweed’s regenerative potential. Under her leadership, Sway has developed TPSea™—a home-compostable polymer made from seaweed that matches the performance of conventional plastics while decomposing into healthy soil. Their film and bag products are plug-and-play compatible with existing plastic infrastructure, enabling brands like J.Crew, Burton, and Eco‑Enclose to scale the use of seaweed-based packaging.
She explains that “seaweed is the most regenerative feedstock on Earth … it grows incredibly quickly, requires no fresh water or pesticides … and is available on nearly every coastline”. Sway’s mission: not just to replace plastic, but to replenish ecosystems, from ocean farms to compost piles.
In Italy, Catia Bastioli leads Novamont, one of the most influential bioplastics companies in the world. Under her leadership, Novamont has developed materials made from renewable agricultural waste, proving that sustainability and industrial performance can coexist.
Meanwhile, Florence Gschwend, co-founder of Lixea in the UK, is using waste wood to create bio-based chemicals that could replace petrochemical plastics. Her work brings circularity into industrial chemistry, offering a glimpse of what a plastic-free supply chain could look like.
Advocating for a Global Shift
Not all change happens in the lab. Dianna Cohen, co-founder of the Plastic Pollution Coalition, has built a global movement to eliminate single-use plastics and support systemic policy change. Her voice has helped reshape how businesses, events, and even entire cities think about plastic.
Judith Enck
, President and Founder of Beyond Plastics (USA), is the former EPA Regional Administrator under Obama. Judith launched Beyond Plastics at Bennington College in 2019 to build a national movement to end single-use plastic pollution. Her organization combines high-level policy advocacy—pushing for bottle-deposit schemes, extended producer responsibility, moratoriums on new petrochemical plants, and a strong national packaging reduction bill—with empowering local action through community groups and student leadership. As Judith has explained, “It really is a global issue and it’s going to take a global solution… The United States is the top producer of plastics, so we should be the ones working the hardest to solve this”. Through Beyond Plastics, she’s laying the groundwork for legislative change, environmental justice, and widespread citizen engagement.
A Future Led by Women
These women, and many others, are redefining leadership in sustainability: science-driven, systems-oriented, community-rooted, and circular by design.
At Women in Cleantech and Sustainability, we believe that solving the plastic crisis requires more than innovation. it requires inclusion. The more we elevate diverse voices and leadership, the closer we get to solutions that work for everyone.
