Have you ever wondered what happens to your food waste? In this post, we’ll be telling you about the process of anaerobic digestion and explain how your food waste can be used to power and heat your own home.
Stage 1: Food Processing
First, after collecting your food waste, it is transported and macerated into a pulp which is then heated to 70°C to kill all the pathogens.
Stage 2: Anaerobic Digestion
The pulp is pumped into large tanks (called digesters) which contain cultures of anaerobic bacteria. These bacteria digest the waste over approximately 55 days.
Stage 3: The Production of Biogas
The process of anaerobic digestion produces biogas which is 60% methane and 40% carbon dioxide. This is ready to be used as liquid bio-fertiliser.
Stage 4: Energy Production
The energy stored in the biogas is converted into electricity and heat, and biomethane which is used as vehicle fuel.
Stage 5: Circular Economy
Therefore, your food waste can be used as fertiliser, vehicle fuel and used to heat and power your own homes.
And there you have it! I hope this will encourage you to collect your food waste, and if you ever need a food waste bin and collection service, feel free to contact us at email@example.com or phone us on 01392 247035
