    Kerzers inaugurates district heating

    Groupe E inaugurated its new district heating plant in Kerzers with open days on 15 and 16 November. According to a press release, the plant will have a capacity of 31 megawatts when completed and can therefore generate 61,000 megawatt hours of heat per year. The heat will be supplied to over 90 households, vegetable growers, the Papiliorama and public buildings.

    The plant will be heated to 90 per cent with wood chips from the region. This will save around 9000 tonnes of CO2.

    It is the third-largest district heating plant of the Fribourg energy supplier after the one in Fribourg and in the Entre-deux-Lacs region.

  • Energy contract signed for sustainable neighbourhood in Romont

    Energy contract signed for sustainable neighbourhood in Romont

    Granges-Paccot-based energy supplier Groupe E and KAAB have signed an energy contract for the La Maillarde neighbourhood in Romont. According to a press release, the 40-year contract covers the supply and utilisation of internal waste heat, the provision of a microgrid infrastructure and the installation of solar modules. Groupe E will supply energy to the site on behalf of KAAB, which will ensure the operation, maintenance and financing of the systems.

    Heat is supplied via the district heating network of the municipality of Romont. The network managed by Groupe E is mainly fuelled by wood chips from local forestry and waste heat from the roasting systems at the Nespresso plant. A gas-fuelled auxiliary heating system is provided for long periods of cold weather.

    The electrical system is controlled by the neighbourhood’s own microgrid. This is fed by a photovoltaic system with an output of one megawatt. It generates around one gigawatt hour of electricity per year.

    The La Maillarde neighbourhood, which is owned by KAAB, was used by the multinational company Tetra Pak until 2016. From 2025, watch manufacturer Rolex will set up shop there, creating around 250 new jobs in the region. The final La Maillarde project envisages an area of 40,000 square metres. Currently, 19,000 square metres are in use.

  • Biochar makes the Swiss more sustainable

    Biochar makes the Swiss more sustainable

    The Swiss Wrestling and Alpine Festival ( ESAF ), which is held every three years, will take place in Pratteln from August 26th to 28th this year. Subsequently, Industrielle Werke Basel ( IWB ) will process the 245 cubic meters of sawdust used for the sawdust rings and the wood chips from other areas of the festival site into around 8 tons of biochar, IWB informed in a statement . Around 20 tons of CO2 are stored long-term in this biochar. The project is part of the federal government's sustainability strategy.

    Sawdust is in itself a climate-friendly material because it is CO2-neutral, explains IWB. However, the conversion into biochar further improves the CO2 balance. Because the biochar obtained in the pyrolysis process in the absence of oxygen and at temperatures of 600 degrees Celsius removes the CO2 from the atmosphere over the long term. As a "welcome by-product", the pyrolysis also produces waste heat, which IWB feeds into the district heating network.
