Question :
Do biodegradable plastics interfere with recycling?
Answer:
Recyclate and recycling
Recycled ordinary plastics are OK, but they are not degradable and will still lie around in the environment for decades. However, ordinary plastic and recycled plastic can now
be made oxo-biodegradable using d2w® additive. Conversely, d2w® products can be recycled and provided that regard is had to inclusion-rate and stabilisers where necessary, the recycled plastic will not be degradable unless more d2w® is added.
Oxo-biodegradable vs. Hydro-biodegradable
Oxo-biodegradable plastics can be recycled and can be made from recyclate, but hydro-biodegradable plastics cannot.
The degradation of oxo-biodegradable plastics is controlled by stabilisers which inhibit abiotic oxidation. The same stabilisers control the performance of plastics during reprocessing and second use. No equivalent stabilisation procedure is possible in the case of hydro-biodegradable polymers, and such bio-based polymers are not normally physically compatible with main- stream polymers.
