We have partnered with a number of Anaerobic Digestion specialists, all of who provide recycling services for a wide variety of solid and liquid organic and food wastes via a network of industry-leading facilities. This puts Grundon in a unique position that all of our depots have access to food waste recycling facilities and we have the capacity available to ensure that your food waste can be sent for treatment at Anaerobic Digestion. How does the Anaerobic Digestion process work? Anaerobic Digestion is a biological treatment process in which micro-organisms break down organic material, such as food waste, in the absence of oxygen, to create a biogas. Food waste arrives Food waste arrives at the Anaerobic Digestion facility, where it is tipped into a bunker before it is de-packaged and macerated. Digester tanks The macerated food waste is then placed into large sealed oxygen-free digester tanks. Biogas creation During the Anaerobic Digestion process, the food is broken down by micro-organisms, creating a biogas (methane and carbon dioxide) and a rich liquid fertiliser called digestate. Organic fertiliser The digestate can then be sent to for spreading on farmland as a valuable organic fertiliser which enriches the soil without the use of petrochemical fertilisers, which are costly to the environment. Renewables The biogas is then either cleaned so that it is injected back into the gas network, or it is burnt into order to create renewable electricity for the National Grid. The Anaerobic Digestion process covers renewable energy from the food waste, reducing and eliminating the need to extract natural gas or import it from abroad, as well as the reliance of using fossil fuels to generate electricity.
