Insights from Braskem on why bio-based polyethylene is reaching a turning point.
Bio-based plastics are often discussed as part of the sustainability transition, yet they are still frequently misunderstood or underutilised. As pressure grows to decarbonise packaging while maintaining performance and circularity, bio-based plastics are increasingly being recognised as a practical evolution of conventional plastic rather than a replacement for it.
This article is based on a recent LoopedIn interview with Richard Lambert, Business Development & Partnerships, Biopolymers EMEA, and Anisa Jane Gallagher, External Affairs EU and UK at Braskem. Drawing on their insight, it explores why bio-based plastics such as I’m green™ bio-based polyethylene may represent a missed opportunity, and why that is now starting to change.
Bio-based plastics build on what already works
One of the key messages from Richard is that bio-based plastics succeed when they respect the reasons plastics are used in the first place. I’m green™ bio-based polyethylene is produced using ethanol derived from sugarcane, yet it is chemically identical to fossil-based polyethylene, delivering the same performance characteristics.
This compatibility is critical. Bio-based PE can be processed using existing manufacturing methods and can be recycled via established plastic waste streams, enabling circularity without requiring fundamental changes to infrastructure or design.
Rather than introducing complexity, bio-based plastics allow businesses to reduce reliance on fossil feedstocks while preserving functionality, efficiency and reliability.
Scalability and versatility are already proven
Anisa highlights that bio-based PE is not limited to niche applications. Because it can be processed through blow moulding, injection moulding and film extrusion, it is suitable for a wide range of rigid and flexible packaging formats.
Applications include food and drink containers, cosmetic packaging, and e-commerce mailing solutions, areas where lightweight performance, strength and protection remain essential. For businesses balancing sustainability targets with operational requirements, this versatility makes bio-based plastics a credible, scalable option.
At Duo, this capability is already being translated into practical solutions. We create GreenPE Mailing bags for our clients, using plant-based polyethylene to deliver the same protective performance expected from mailing bags. As the first UK manufacturer to produce GreenPE mailing bags, Duo is enabling brands to adopt bio-based plastics without compromising on quality or functionality.
Misconceptions remain the biggest barrier
Despite growing interest, Richard and Anisa both point to misconceptions as the main factor holding bio‑based plastics back. General attitudes towards plastic can limit consideration of innovative plastic solutions, while plant‑based materials are often assumed to be small scale or environmentally questionable.
Anisa addresses common concerns about feedstocks, explaining that the sugarcane used for I’m green™ bio‑based comes from existing agricultural land and is already cultivated for sugar and ethanol production. The bio‑based polyethylene is a co‑product, not a driver of deforestation or food competition, and residual materials are reused to generate energy.
Improving understanding across the value chain remains essential if bio‑based plastics are to be assessed on evidence rather than assumption.
Policy is reinforcing confidence
The interview also points to meaningful policy momentum. Bio‑based plastics have been included in Article 8 of the EU Packaging and Packaging Waste Regulation (PPWR), requiring the European Commission to assess their environmental performance and sustainability.
Alongside this, the EU is developing a new Bioeconomy Strategy, expected by the end of 2025, aimed at supporting innovation, job creation and market growth across the bioeconomy. Together, these developments signal increasing recognition of bio‑based plastics as a legitimate component of the circular economy.
As Richard notes, regulatory clarity can help ensure bio‑based plastics are no longer seen as a missed opportunity, but as a mature solution ready to scale.
What this means for businesses
The message from Richard and Anisa is clear: bio-based plastics are not about replacing plastic but improving how it is sourced and produced. When supported by evidence, infrastructure and policy, they offer a practical route towards lower-carbon packaging without sacrificing performance.
