Making Compost
- Incoming waste is sorted daily to separate contaminants and larger pieces of wood.
- This sorted waste is shredded once a week and placed into sterilisation bays, where the material is aerated, watered and naturally heats to > 65ºC. This kills the bugs and weed seeds.
- After about a week the material is transferred to maturation windrows, which are turned weekly.
- Matured compost is screened to remove the oversize.
- Compost is moved to field stockpiles for spreading later.
- The compost is spread on the fields between harvest and establishing the next crop to improve soil quality and provide nutrients for the following crop. This reduces the need for inorganic fertilisers.
