Transforming Food and Green Waste Processing - Biffa

Food & green waste processing 

Using anaerobic digesters, Biffa generates renewable bio-methane from food and green waste we receive. Anaerobic digestion technology generates biogas used to power our sites and any surplus is diverted to the national grid.

What is anaerobic digestion?

Anaerobic digestion (AD) is a sustainable process where organic matter, such as food or plant waste, is broken down by micro-organisms called methanogens in the absence of oxygen. This creates biogas (a mixture of methane and carbon dioxide) which we can use as a source of energy. 

This process also creates a bio-fertiliser by-product. This is rich in nutrients such as nitrogen, potassium, and other elements, and can be used in agriculture or horticulture as liquid fertiliser, or even animal bedding, as part of the circular economy.

 

We receive and process 315kT of bulk food waste annually

Investing to tackle food waste
The UK generates around 19 million tonnes of food waste per year. We have invested £24 million in our flagship AD plant, Poplars in Cannock, to help divert as much as possible to be recycled or reused. It is the most efficient AD plant in the UK, generating up to 6.5m MW of electricity – enough to power 15,0000 homes.

Biodegradable waste from Mechanical & Biological Treatment (MBT)
Mechanical and Biological Treatment is not a single technology. It is a combination of sorting and treatment technologies, to help increase the amount of ‘black bag’ waste sent to AD to generate energy, and residual waste used to create Refuse Derived Fuel (RDF).

At our MBT facility in Horsham waste is shredded and then sorted into biodegradable waste, metals, or paper and plastic. Metal is sent on for recycling. Shredded paper and plastic is used to produce Refuse Derived Fuel. And the biodegradable waste is broken down by Anaerobic Digestion.

Green waste composting in just 12 weeks
Biffa’s composting service takes green waste to be shredded and treated to produce compost and a soil improver, all in just 12 weeks. We use two forms of composting - (1) open windrow composting and (2) in-vessel composting. Batches are sampled regularly to evaluate the nutrient levels and make sure the product is suitable for specific soil types and crops. 

Our services help local authorities, as well as other commercial organisations, dispose of their green waste in a safe and efficient way.
