Question: Can you recycle scum?

Daphne Ng answered on 22 Mar 2012:

We can’t recycle pond scum in the same ways as recycling waste. But what we can do is that we can use the leftover pond scum residue after the extraction of the useful compounds to make other products such as animal feed as the leftover residue is rich in protein. So every part of the pond scum is used!
