Answer 1

1. Biowaste Collection: Only bio-waste can be used in a bio-gas plant. For example, food waste and plant waste.
2. Slurry formation: Slurry is a semi-solid product made from a mixture of bio-waste and water in the mixing chamber.
3. Anaerobic digestion: In the absence of oxygen, the micro-organism breaks down slurry. This phase can take a couple of weeks to complete.
