Biogas

Eco Sustainable Solutions Biogas

Our Biogas Energy is both innovative and cost effective. It involves excess low grade heat, warming your leftovers and converting the resultant gas into power.

Anaerobic digestion is a collection of processes by which microorganisms break down biodegradable material in the absence of oxygen.

Our Process

Biogas is reached by Anaerobic Digestion - the following steps are how we achieve this renewable energy source:

1. The local authority organise a rubbish collection service where food waste caddies are collected and loaded onto rubbish trucks in bulk.

                                                                         |

2. The food waste material is then taken to Piddlehinton and tipped in a loading bay.

                                                                         |

3. The material is fed into a large blender where it is processed.

                                                                         |

4. The food waste is mixed with water, to create a liquid which has a porridge like consistency called digestate.

                                                                         |

5. The food waste passes through a washing machine which is designed to extract the plastics and metals.

                                                                         |

6. The waste is then fed into a holding tank where it is kept for 3 days. This allows for a consistent feed and operation of the plant.

                                                                         |     

7. The substance is then pumped into the digester & stirred.

                                                                         |

8. The mix is kept in this tank for 55 days. A little bit is fed in and a little bit is fed out, every day.   

                                                                         |

9.From this mix, a gas is produced of which 55% is methane. At this stage, the before mentioned digestate, is heated to 72 degrees for 1 hour, where it is pasteurised.

                                                                         |

10.The gas is extracted and pumped through a carbon filter to scrub. After pateurisation is complete, the digestate material is then exported as an agricultural fertiliser.

                                                                         |       

11. The gas then passes to the enginges which drive the generator. The generator produces electricity.

                                                                         |   

12. The plant supplies power to the grid, powers the plant and the local mill.    

End Results

The end results of the Anerobic Digestion process can be summarised as follows:

  • Digestate - an agricultural fertiliser - high in organic value, supplying farms and farmers with healthy yields.
  • Biogas - a renewable energy in the form of gas which passes through a generator, producing electricity powering the plant and feeding the grid.

Additional Info

We process over 10,000 tons of food waste, every year.

All cooked and uncooked food can be recycled including: 

  • Meat, fish and bones
  • Fruit and vegetables
  • Dairy
  • Bread, cakes and pastries
  • Pasta and rice
  • Teabags and coffee grounds
  • Egg shells
  • Plate scrapings

Please DON'T put these into your food waste container:

  • Garden waste
  • Plastic, paper or cardboard recyclables (Big Bin please)
  • Plastic bags
  • Oil or liquid fats
  • Pet waste
  • Nappies

Facts & Data


Anaerobic digestion (AD) is the process by which organic materials in an enclosed vessel, are broken down by micro-organisms, with the absence of oxygen.

The anaerobic digestion process produces biogas (consisting primarily of methane and carbon dioxide). This is why AD systems are sometimes referred to as biogas systems.
