Hemswell Biogas is a large processor of food waste located in Lincolnshire, and has been designed to handle a wide range of waste feedstocks. Through a process called Anaerobic Digestion it utilises the waste as a raw material to create methane, which in turn is used to generate electricity that is 100% renewable and exported to the national grid.
The waste can be in solid, liquid or sludge form, packaged or unpackaged. Out-of-date and damaged foods from retailers, supermarkets and factories or food waste from restaurants, pubs and hotels, offices, hospitals and schools. In addition, domestic kitchen food waste, waste from food processing factories, plus animal by-products (Category III) from the food industry, can all be processed by the plant.
Waste recycling at the Hemswell Biogas site assures significant carbon reduction benefits.
- By processing a wide range of waste to produce electricity that is sold back to the grid,
- capturing excess heat generated by the plant to generate additional electricity, and provide heat for onsite industry that requires a heat process.
However, the most unique of these benefits is,
- the use of digestate bio-fertiliser, which is rich in Nitrogen (N), Phosphate (P) and Potassium (K). It’s pumped straight from the plant onto growing crops on the surrounding farmland, via a network of lagoons and underground pipes, without having to go back into a vehicle. The use of carbon-intensive synthetic fertiliser is reduced by 70-80% through this process, which is an important factor in Corporate Social Responsibility (CSR) programmes and raising customer awareness.
