d2w® Biodegradable Plastic Technology - 2026 market outlook

Symphony Environmental Technologies Plc ("Symphony", AIM: SYM), a global leader in smarter, safer, and sustainable plastic and rubber technologies is pleased to issue this New Year market outlook, reflecting our strong belief that growth and market adoption for d2w® biodegradable plastic technology will accelerate globally. This non-disruptive, scientifically proven solution is designed to biodegrade in real‑world environments, including and at sea, without leaving persistent microplastics.

Expanding Global Regulatory Acceptance

d2w® technology continues to gain traction worldwide. More than 35 countries now officially recognise in legislation, regulation or test standards, this type of biodegradable plastic manufactured and tested to internationally accepted criteria.

This wide acceptance or recognition demonstrates a growing move in global environmental policy toward proven biodegradable technologies, reflecting the fact that plastic is essential for modern life but recognising that existing waste‑management policies cannot prevent plastic waste getting into the environment. It is now more necessary than ever to make plastic so that it will quickly biodegrade in the open environment - and not just in a composting facility.

Products made with d2w technology meet this need, offering a scientifically tested solution that does not generate microplastics, thereby addressing one of the most pressing concerns in global sustainability.

Backed by Four Decades of Independent Science

d2w® is supported by over 40 years of independent scientific studies, and compliance with official standards - including American ASTM D6954; British BS 8472; French AFNOR T51‑808; Saudi Arabian SASO 2879; Emirates ESMA 5009; and Mexican NMX‑E‑288‑NYCE‑2022. Rigorous evaluations by international test-houses according to these Standards confirm that products made with d2w®:

· Biodegrade fully in the open environment, including oceans

· Do not generate persistent microplastics

· Remain recyclable during their useful life

· Provide a cost‑effective, drop‑in alternative to conventional plastics without altering manufacturing processes or materially increasing cost.

Positive Commercial Outlook

The global regulatory landscape is increasingly focused on solutions to plastic pollution, and the growing corporate demand for certified biodegradable materials positions d2w® as a scalable technology ready for widespread adoption.

As sustainability requirements intensify - particularly in high‑growth markets - d2w® provides manufacturers and brands a practical, cost-effective, and scientifically validated pathway to achieve compliance, reduce environmental impact, and strengthen ESG performance, all without disrupting existing supply chains.

We are encouraged by feedback from our distributors and other market sources indicating that demand is expected to rise across the Middle East, Asia, Latin America, the Caribbean and Africa, with particularly strong momentum building in India. Symphony anticipates continued commercial acceleration driven by:

· Strengthening international recognition of biodegradable standards

· Increasing legislation and enforcement thereof affecting conventional plastics

· Growing interest from multinational brands and packaging suppliers

· Ongoing progress in scientific validation and certification
