CIRCULAR ECONOMY: USING HORSE MANURE TO GENERATE POWER

 

 

This is the aim of the future WtE facility designed to recycle organic waste using anaerobic digestion and gasification, on a former disused quarry in the town of Gouvieux, near Chantilly (Oise, France). Egis  is responsible for the project management consultancy for this regional environmental project, as part of a circular economy approach: creation of a solution for recovering/recycling horse manure generated by regional stud farms and breeders, as well as green waste from nearby communities.

The unit will implement the following recovery and recovery techniques:

  • Anaerobic digestion of 30,000 tonnes per year of equine manure on straw, along with green waste, for an output of 5 MW of biogas, which will be injected into the GRTgaz network.
  • Gasification of 9000 tonnes per year of equine manure on chips and woody green waste, generating 3 MW of thermal energy.
  • Recovery and reuse of digestate (2) to produce a marketable organic soil conditioner.

THE ECONOMY OF CO2 REALIZED ONCE THE PROJECT WILL BE CONCRETIZED WOULD BE ABOUT 5 000 TONS CO2 /YEAR

The project management consultancy assignment will focus on the operational phase of creating the final detailed design, followed by construction and handover, as well as startup of the facility.

(2) Digestate: is the material remaining, or “digested” waste, after the anaerobic digestion of organic waste. Digestate is made up of excess bacteria, non-degraded organic matter and mineralised material. After treatment it can be used as compost.
