Anaerobic Digestion is recognised as the Government’s preferred recycling treatment solution for food waste and, with costs approximately two thirds less than landfill or incineration fees, it provides an extremely cost-effective and environmentally friendly option for disposing of your food waste.
Grundon has partnered with Anaerobic Digestion specialists Agrivert, to provide recycling services for a wide variety of solid and liquid food wastes using its Anaerobic Digestion facilities. This puts us in a unique position in that all of our depots have access to a network of food waste recycling facilities and we have the capacity available to ensure your food waste goes to Anaerobic Digestion.
In keeping with our strategy of investing in industry-leading technology, Grundon has taken a 15% equity stake in Agrivert’s West London Anaerobic Digestion facility in Chertsey, Surrey. The £11 million plant processes up to 50,000 tonnes of food waste a year, producing 2.4MW of green electricity (enough power for over 4,800 homes).
What are the benefits of Anaerobic Digestion?
One advantage of disposing of your food waste via Anaerobic Digestion is how cost-effective it is. Food waste weighs considerably more than other comparative waste streams such as general waste or mixed recyclables. This means that by recycling your food waste and sending less to landfill you could significantly cut the amount of landfill tax you have to pay. Furthermore, this could lead to a substantial reduction in the size and frequency of your general waste collection needs.
The environmental implications of Anaerobic Digestion are manifold. Unfortunately, at the moment the majority of food is sent to landfill, where as it biodegrades it releases harmful greenhouse gases, such as carbon dioxide and methane, which contribute to climate change. Due to this pollution it is widely expected that Government will ban food waste from landfill in the near future. By recycling your food waste you can reduce the amount of food sent to landfill and reduce your carbon footprint.
Anaerobic Digestion considerably reduces these emissions, and instead produces valuable renewable energy and nutrient rich fertiliser which is fully compliant with PAS 110.
How does Anaerobic Digestion work?
Anaerobic digestion is a biological treatment process in which bacteria break down organic material (the food waste) in the absence of oxygen and produce biogas. When the food waste arrives at the Anaerobic Digestion facility it is depackaged, macerated and then digested anaerobically in large sealed tanks. During the digestion process, the food waste breaks down to produce biogas (methane and carbon dioxide) and a liquid fertiliser called digestate. The valuable organic fertiliser is used on local farmland and gas engines convert the biogas into electricity which is then fed to the National Grid.
Anaerobic Digestion is a sustainable outlet for your food waste and is another great example of how Grundon can reduce the financial and environmental impacts of your waste.
