Rotating trommel

This separates waste by size, into small and large. The small waste contains organic matter; the large waste, recyclable material, that citizens have not sorted correctly.

The waste goes into a cylinder with holes (90 mm holes). The organic matter, which is smaller, falls through the holes. The other waste, which is larger, gets to the end of the cylinder.
