ENZYMATIC HYDROLYSIS
ADVANTAGES OF OUR PROCESS
Straightforward process
Our process can be operated in a low-temperature range and under ambient atmosphere which allows a lean technical setup. This enhances high reliability while minimizing both CAPEX and OPEX, enabling competitive unit costs for industrial-scale applications.
Lean pre-treatment
Using post-consumer PET packaging allows us to bypass complex and costly pretreatment steps. We only need to perform basic cleaning and cutting of the material before processing.
Persistent enzymes
Our enzymes are designed to be highly thermostable, ensuring they remain effective and maintain consistent degradation rates. PHL7 Generation 4 enzymes have demonstrated thermo-stability at temperatures exceeding 95 °C.
All polyesters
Our process enables the depolymeri-zation of all polyesters.
With enzyme customization, we can potentially process multi-layer products and mixed-material waste. We have already demonstrated feasibility with PET, PLA, PBAT, PBS & TPS.
Fast depolimerisation
Our high performance enzymes allows us to achieve a complete disintegration in a short time. With PHL7 Generation 3 we can depolimerise PET post consumer packaging in 13 hours.
Low energy input
Our process operates at temperatures below 70°C, requiring only a moderate amount of heat. This heat can easily be supplied using waste heat from other industrial processes or generated from renewable energy sources.
We are currently scale up the process to a 100-liter capacity in 2025 and to 1 cubic meter in 2026. This will demonstrate its readiness for industrial-scale application and provide valuable knowledge for the further scaling and optimizing.
