The ENCORE project is set to address the critical environmental challenge posed by the millions of tons of nylon waste generated annually from sources such as clothing and fishing nets. Current recycling methods for nylon are inefficient leading to low recycling rates globally. However, the ENCORE project proposes a sustainable solution by leveraging Nature's own tools – enzymes – to break down nylon into reusable chemicals.

The initial phase of the project involves identifying bacteria capable of decomposing nylon. Bacteria naturally produce enzymes to break down environmental molecules, making them ideal candidates for this task. Once suitable bacteria are found, the project will employ a variety of advanced techniques to understand the mechanisms behind their nylon-degrading abilities.

In the final phase, the efficacy of these enzymes will be tested on real nylon waste. The ultimate objective of the ENCORE project is to establish a novel recycling process with a significantly lower carbon footprint compared to current methods. By developing an eco-efficient closed-loop system, the project aims to transform nylon waste into new nylon products, reducing the need for fossil fuel-derived materials.

The innovative approach, which will be further developed and tested by the project partners, promises to pave the way for sustainable nylon recycling, marking a significant step forward in our efforts to mitigate plastic pollution and promote environmental sustainability.
