The process
We use a specialised process called Anaerobic Digestion to recycle unwanted food waste.

Proven to work across Europe, our technology converts unwanted waste into renewable energy, which our London and Widnes plants supply direct to the National Gas Grid, and ReGrow, our PAS110 accredited nutrient-rich biofertiliser. ReGrow is an excellent supplement for enhancing soil health and fertility, making it great for food crops.
 

Food waste recycling with ReFood is the perfect way to lower your company’s carbon footprint and costs. And our end-to-end service gives peace of mind that you’re disposing of food waste in the most sustainable way.

 

It’s the closed-loop process that keeps on giving.

At our Doncaster plant, the gas is used to fuel large industrial-scale combined heat & power engines, the electricity generated is delivered directly to the National Grid – enough energy to power 10,000 homes per year. The heat produced by the engines is used to produce hot water and steam for the process and the pasteurisation of the raw food waste.

 

At our London and Widnes plants, the biogas undergoes a further refining process to remove carbon dioxide and volatile organic compounds. Once the gas has completed the refining process an odorant is added to the biomethane before it is pumped directly into the National Gas Grid. The process produces enough gas to supply up to 12,600 homes per year.

 

Once the biogas process has been completed the remaining liquid is transformed into our ReGrow bio-fertiliser for local farming and agricultural use.

How we turn food waste into good

We use the UK’s most advanced Anaerobic Digestion technology to provide an end-to-end recycling process that creates renewable energy and fertiliser from waste.

Step 1

Placement of recycling bins

We provide our customers with a choice of recycling bins to store their food waste. These are available in 240 litre wheeled bins with optional larger containers if needed.

Step 2

Food waste collection

Recycling bins are collected to a bespoke schedule by our own fleet of liveried trucks and taken to our Anaerobic Digestion (AD) plant. All bins taken are replaced by fresh, sanitised ones to ensure the highest levels of hygiene are maintained at all times.

Step 3

Recycling at our plant

On arrival at our plant, food waste is separated from any packaging. Then, using the AD process, organic matter is biologically broken down in an oxygen-free environment. During this process large amounts of heat and biogas is generated which is made up of methane and carbon dioxide.

Step 4

Production of renewable energy

All our facilities are powered by heat and steam generated by renewable energy – not fossil fuels. Our London and Widnes plants export renewable energy directly to the National Grid and our Doncaster site uses its own renewable energy.

 

Meanwhile, our environmentally friendly, nutrient-rich biofertiliser is sold to local farmers and growers. ReGrow directly displaces fossil fuel-based fertiliser, maintains the PAS110 quality protocol accreditation and upholds an exceptional level of quality and safety.
