I have a general understanding on how to recycle glass, plastic, compost etc at home. But sometimes I still have a doubt, e.g. how to recycle the lid of a jar, or the wrapping around a 6-pack of water bottle.
What I'm looking for is a database where for each product (for example identified by Universal Product Code), it tells me how to recycle its individual parts.
I suppose a DB telling me exactly in which material each component is made of would be enough.
It might be also separate databases, I suppose one might possibly find per-country databases more easily.
