DESCRIPTION
Thanks to its agricultural heritage, Bessières is ideally positioned to host an innovative project to establish a local and sustainable circular economy, connecting waste heat producers and cold consumers.
The Waste-to-Energy Unit is a household and other waste treatment center.
The facility processes approximately 196,000 tons of waste annually, producing electricity and heat.
Part of this heat is recovered through a heating network of vegetable greenhouses. Nevertheless, recovery remains limited, and a large part of this heat is still lost and released into the air.
The Bessières Greenhouses, located a few hundred meters from the incinerator, is a market gardening farm specializing in the production of tomatoes in greenhouses. The greenhouses cover 10 hectares of land for an average annual production of 6,000 tons of tomatoes. The need to maintain an adequate temperature to conserve the tomatoes raises a major environmental challenge: the consequent refrigeration requirements. Indeed, refrigeration systems, although essential to preserve the quality of tomatoes, contribute to energy consumption and greenhouse gas emissions.
With its “Low Heat to Cold” (LH2C) thermal battery technology, Water Horizon will distribute renewable cold from the waste heat of the incinerator
The LH2C battery is charged using heat from the UVE. Once full, it is used on the same site to provide cold.
IMPACT
UVE de SETMI:
→ Better image
→ Reduced environmental impact
→ Upgrade and continuous innovation to meet changing regulations
Bessières Greenhouses:
→ Lower operating and maintenance costs (boilers and chillers)
→ Reduction of GHG emissions
→ Temperature management (accuracy, stability) to ensure the quality and safety of stored products

TECHNOLOGY
Over the past 7 years, WATER HORIZON has developed a unique skill and technical know-how in the recovery of waste heat and the production of renewable cooling.
In Europe, industrial waste heat represents the equivalent of 100 nuclear reactors.
It is on the basis of this significant observation that Water Horizon has developed its Low Heat To Cold (LH2C) technology: Recover waste heat at low temperatures (50-100°C) and transform it at the same place in the form of cold at a positive temperature (>0°C).
Water Horizon takes care of everything! Whether you are a producer of waste heat or a consumer, we take care of finding your peer, sizing the project, financing it and operating it.
