Consumerium's information on materials, their production, use and recycling

Biowaste

Recycling biowaste

Running an private biowaste recycling facility or compost as it's called you might have noticed some things like citrus fruit peels compost quite slowly compared to say some other fruit leftovers.

In centralized biowaste management this might not be such an big issue due to the longer time horizon of the activity. Drying biowaste before you put it into the recycling bin helps you avoid fungus growth allowing you to take it out less frequently and also makes the job of the collector nicer


Carton and cardboard

Packaging cartons and cardboard

These are often made from recycled paper and can be used to make more cardboard.


Glass

Recycling glass

Effective recycling of glass (mostly bottles currently) relies on a refund system where a small refund is paid for the return of the package to the producer for reuse after it has been cleaned and checked to be in a functional condition.

Also recycling glass containers without using them again is useful though if the glass is broken and crushed in the process to just create more raw material. Though this consues much more energy as the glass is melted once again


Metals

Metals recycling

Again here there are many resolution levels. Not knowing about the technology in this area I'm not very equiped to write anything about this. Different metals have different prices and different raw material extraction costs so that could be used as guideline.

Open questions:

  • How does plastic, rubber or paper that is attached to some metal surface affect the usability of the metal?

Paper

Recycling paper

There are many different classes of papers in high resolution recycling. Office paper (print outs) are different from magazine papers and so on. This further separation of paper into different bins is done somewhere and somewhere it's not, but we should work to make it more available as all recycling

  • Small metals such as magazine or tabloid binders are not a big problem since they can be detected and removed by machines in the processing.
  • Plastic and glues from envelopes are more of a problem in the recycling process. Someone with more knowledge on this could helpfully write something here.
