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 | In centralized biowaste management this might not be such an big issue due to the longer time horizon of the activity.

== 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. | 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. | ||

Not knowing about the technology in this area I'm not very equipped to write anything about this. Different metals have different prices and different [[raw material]] extraction costs so that could be used as guideline. | ||

== 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 | There are many different classes of papers in high resolution recycling.
