Eco Purge: Biodegradable Plastic Designed To Break Down Microplastics
Many biodegradable plastics aim to reduce future plastic waste. Eco Purge, developed by Irish innovator Arya Satheesh, takes this idea a step further. The plant-based material not only replaces conventional plastics but also helps remove microplastics that already exist in the environment.
The material responds to the growing problem of microplastic pollution. These tiny plastic particles contaminate oceans, rivers, soil and even food systems. Once released, they are extremely difficult to remove.
Bioplastic With Built-In Enzymes
Eco Purge, which was the European winner of The Earth Prize 2026, combines a biodegradable polymer with specialised enzymes that break down microplastics. The material stores the enzymes inside its structure during use. As the bioplastic degrades, it gradually releases them into the surrounding environment. This process gives the material a dual function. It serves as a biodegradable alternative to conventional plastic while simultaneously helping to reduce existing microplastic pollution.
The enzymes can operate in different environments, including soil, freshwater and seawater. As a result, the material could offer benefits across a wide range of applications and waste streams.
Designed For Packaging And Compostable Products
Researchers have already developed Eco Purge into a working prototype. Satheesh worked with experts from University College Dublin (UCD), Atlantic Technological University (ATU) Letterkenny and the BiOrbic Bioeconomy Research Centre during the development process.
The team is now exploring applications such as packaging and compostable waste bags. These products often have a short lifespan and generate large volumes of waste. A material that combines biodegradability with environmental remediation could therefore offer additional value.
For packaging designers, Eco Purge demonstrates how materials can contribute to environmental recovery rather than simply reducing harm. The concept aligns with growing interest in regenerative design and circular material systems.
Towards Regenerative Materials
Material innovation increasingly focuses on creating positive environmental impact. Designers and manufacturers now look beyond renewable feedstocks and low-carbon production. They also consider how materials behave at the end of their life.
Eco Purge reflects this shift. Instead of acting solely as a substitute for conventional plastic, the material actively addresses an existing environmental problem. Although further testing and scaling are still required, the project highlights the potential of multifunctional biomaterials that combine circularity with environmental restoration.
