Separation Rules

For bio-waste we have to be somewhat cautious in what we are separating because, compared to packaging, here there is no label to tell us what we should or shouldn't put for Bio-waste. So we decided to give you some tips on materials that you should or should not separate in bio-waste, we hope it helps you.
Above all remember that Bio-residue is always in the brown bin!

What happens to bio-waste?


After being collected, the bio-waste goes through a composting phase, a process that occurs through the action of microorganisms that transform this bio-waste into a final product, called compost.

After a few months, the waste placed in the composter turns into compost, a dark, earthy-looking organic material with no smell or a forest smell and excellent fertilizing qualities.
