Birch Biosciences

Birch is proud to be a 2026 CDL-Vancouver Climate Stream Graduate! 🎓 A huge thank you to the incredible mentors and the entire CDL team for the guidance and support over the past 8 months as we’ve grown and advanced our commercialization efforts. We’re excited to keep building toward true plastic circularity alongside such an inspiring group of companies driving climate innovation forward. Check them out!

Birch is heading to the Textiles Recycling Expo USA on April 29-30 in Charlotte, NC! Come visit us at booth #410, where our team will be sharing how we’re enabling textile-to-textile recycling using our enzymatic process. Looking forward to meeting with industry colleagues and establishing new partnerships. See you there!   Registration is free: https://lnkd.in/gtjtG4Xh #TRExpoUSA

We’re excited to welcome Camille Herrera, MESM as an Advisor to Birch Biosciences. Camille is a recognized leader in advancing recycled content from PET thermoforms into real-world packaging supply chains. During her time at Driscoll’s, she helped build one of North America’s first clamshell-to-clamshell recycling pathways—scaling postconsumer recycled content while working across MRFs, reclaimers, manufacturers, NGOs, and policymakers. As Birch scales its enzymatic PET recycling platform, Camille’s experience aligning brands, suppliers, and recyclers will help accelerate market adoption and de-risk supply chain integration. Her track record of turning circularity commitments into operational reality strengthens our path to scalable deployment. We’re thrilled to have her supporting Birch’s next phase of growth! #AdvisoryBoard #ClimateTech #CircularEconomy #Recycling #StartupGrowth

I’m delighted to share that I’ve joined Birch Biosciences as an Advisor. For the past six years, I’ve worked on one persistent constraint in PET thermoform recycling: material quality. Time and again, we see the same trade-off — material that is technically recyclable, but unable to consistently meet performance requirements at scale within existing packaging supply chains, or at viable cost. At the same time, climate impact matters. In many advanced recycling pathways, improving material quality can come with significant energy intensity. Sustainability leaders are often forced to balance circularity, performance, and emissions — and typically only get two out of the three. Birch’s enzymatic recycling technology is working to change that equation — producing recycled PET from thermoforms with performance on par with virgin material, enabling bottles and thermoforms to be processed together, and projected greenhouse gas reductions of 70% compared to fossil fuel PET manufacture when implemented at scale. If that combination holds at scale, it’s not incremental. It alters the constraints that have defined recycled content strategy for years. I’m looking forward to supporting the team as they scale this technology for packaging and textiles—and to contributing to what I believe could be a meaningful shift in circular PET. #recycling #circularity #rPET #packaging #innovation
