Food to energy with Andigestion recycling

Jul 26, 2019 | Jenni Ashford

As part of the club-wide commitment to environmental strategies to recycle, reuse and reduce waste, Exeter Golf and Country Club has been working with revolutionary food recycling company, Andigestion.

Based in South Molton, Devon, Andigestion provides an alternative to landfill which in turn reduces greenhouse gas emissions. The recycling of organic, food waste creates a biofertiliser which is used by farmers returning essential nutrients to the land, and biogas which is converted into electricity.

Andigestion uses anaerobic digestion to breakdown organic matter, through a process of mixing, macerating and heating to create a ‘soup’ which is free from bacteria. This is then pumped into digester tanks containing cultures of anaerobic bacteria that digest the waste over a period of 55 days. This creates the biogas, and the remaining 90% of the waste is pumped through a final cleansing stage which produces a digestate liquid, free from pathogens, containing high quantities of nitrogen, potassium and phosphate; all vital nutrients for plant growth.

Anaerobic digestion is the only renewable technology that is scalable to meet 2020 climate change targets.

Landfill waste produces methane which is 20 times more potent as a greenhouse gas than carbon dioxide. Andigestion’s anaerobic digestion process captures the energy stored in the methane and turns it into useful electrical energy and heat and carbon dioxide.

Exeter Golf and Country Club separate all food waste including peelings, out of date food, plate scrapings, damaged stock, frozen or chilled foods, to maximise the food waste sent to process with Andigestion.

Food recycling is one of many environmental commitments the club has made in the past two years, in addition to the removal of single-use plastics, various ecology developments on the golf course and move to the UK’s only environmentally-friendly laundry service, Eco Laundry.
