We have just started looking into cradle-to-cradle and the circular economy as we would like to switch to a sustainable packaging solution which will still meet our clients' requirements (in terms of shape, texture). We are looking for something that is either fully and safely biodegradable if it reaches nature or that is indefinitely recyclable and can stay in the economy as "technical nutrients". For now we are focusing on a small rectangular cufflink box, which currently mainly contains polyurethane plastic and foam, fabric and is covered with paper. We think our best bet would be to use just one type of material instead of combining several ones, to facilitate recycling or the leaching of bio-nutrients.
Our manufacturing takes place in Guangzhou, China, so we would be very interested to see if anyone out there knows something about eco-friendly plastic, paper, ink and glue suppliers in China?
Also, I've read about PHA (polyhydroxyalkanoates) plastic which is both bio-based and biodegradable; does anyone know whether it could be applicable to this kind of packaging, and what is its cost relative to other more common plastics?
Any kind of help, advice or information regarding this matter is deeply appreciated!
I can also send pictures of the package and its composition by email, if it can be useful to clarify any doubt.
Thank you very much!
