Choose a well-drained area before digging pits.
Then dig two pits.

Use one pit to collect animal waste and the other pit to mix and decompose animal waste with the other waste materials.
Mix the plant residues with animal waste like waste from poultry, pigs, goats, cattle and donkeys, thoroughly and leave it to decompose.
Add water to make mixing easier and pave way for faster decomposition.
