Anaerobic Digestion



Anaerobic digestion (AD) is a biological treatment process in which bacteria break down organic material (such as food waste) in the absence of oxygen and produce biogas.

Organic material is depackaged, size reduced, pasteurised and then digested in the Agrivert AD system. Material spends over three months in Agrivert digesters, maximising the generation of methane and carbon dioxide (biogas). Agrivert’s AD process provides operational stability, reliability, efficiency and also ensures compliance with the Animal By-Products Regulations (ABPR).

Our facilities process food waste in virtually any form, including solids, liquids, sludges, packaged, de-packaged, oily and fatty wastes.

Agrivert’s AD biotechnology, developed with technology provider Biogas Weser-Ems, maximises the generation of biogas, which is captured and used to:

  • Provide local populations with a source of renewable energy
  • Generate electricity to be fed into the National Grid
  • Supply methane to the gas grid, or fuel vehicles modified to run on compressed natural gas.
  • Provide thermal energy required to dry biomass

At sites generating electricity, Agrivert achieves an average energy generation of over 96% of the potential energy generation capacity of that site.

In addition to renewable energy, anaerobic digestion produces digestate – an excellent biofertiliser.

Thanks to our agricultural background, Agrivert is well placed to find sustainable outlets for spreading digestate to farmland and to advise agronomists on digestate application. The digestate’s valuable nutrients provide long term benefits to soil and reduce the need for artificial fertilisers.

Agrivert’s process is designed to produce digestate that achieves the industry quality standard, PAS110.

Agrivert’s anaerobic digestion technology helps to lower greenhouse gas emissions by capturing methane that may otherwise have been emitted into the atmosphere from landfill. It also reduces reliance on fossil fuels by producing renewable energy and a digestate fertiliser that displaces the need for artificial fertilisers, which account for around 7% of the UK’s greenhouse gas emmissions.
