Renewable energy for future generations

Project description

The Beauval ZooParc was the world's first zoological garden to install an anaerobic digestion unit. Commissioned in the Spring of 2014, this unit enables the Zooparc to increase its energy independence, reduce its operating costs and treat the manure and green waste generated by its activity, as well as some of the region's organic waste. A symbol of its environmental commitment, the facility produces 265 kW of electricity, reinjected into the ERDF grid, while also heating the Gorillas and Manatees enclosure and the Elephant House.

LEDJO Energie, Evergaz's consultancy firm subsidiary, was the technical partner of the Beauval ZooParc, carrying out the feasibility study and Project Ownership Assistance tasks.



Key data:

  • Treatment capacity: 11,315 metric tons per year
  • Biogas recovery: cogeneration, 260 kWel
  • Heat recovery: heating of the zoo
  • 760 metric tons of CO2 equivalent avoided every year
  • Energy bill reduced by 20%
  • ERDF funding (European Regional Development Fund)
