What input is right for the OWC

Input can be 50% wet waste and 50% dry garden waste. Add 1 kg of Bioculum™ and the OWC is ready to be switched on. The Organic Waste is converted into smooth, homogenized, odour-free raw compost within 15 minutes through a biomechanical process.

How the raw compost is cured

The curing system stabilizes the raw compost through controlled aerobic microbial decomposition. The system doesn’t draw on electricity to produce the heat that is so crucial to the decomposition process.

The heat is generated instrinsically by bacteria of the thermophilic variety. This simply means that the resulting fertilizer is microbial-rich and full of nutrients.

How the cured compost is used

The fertilizer is ready within two weeks which can be used immediately in your gardens and for all your landscaping needs. Since the input is heterogenous, you will have more nutrients in the fertilizer output.
