• WAGABOX® technology
  24 November 2023, by Philippe

  A benchmark solution for landfill gas purification for recovery.
  Coupling membrane filtration and cryogenic distillation to upgrade landfill gas into grid compliant biomethane: Improvement in energy yield compared with cogeneration. Optimized methane capture as there is no limitation in air concentration in landfill gas.
  Example: WAGABOX® in Claye-Souilly, France: Capacity: 130 GWh/y. 21,000 eqCO2 avoided/y. 20,000 households supplied with biomethane.

  El Alto and La Paz – evaluation of airborne particle pollution sources.
  This evaluation of airborne particle pollution sources in Bolivia show that: Local air pollution in La Paz is mainly due to road traffic but additional sources such as waste burning may have non-negligeable impacts. Waste burning contributes only 2 to 5% of total PM10 but contains more than 50% of the PAHs content which are carcinogenic components.

• Geothermal CO₂ capture
  24 November 2023, by Philippe

  Leveraging CO2 dissolution capacity in cold versus hot water.
  R&D project to combine a deep geothermal plant with permanent CO2 storage of incineration flue gases.
  The project aims to: Store 300,000 tons of CO2 (40% fossil) in a deep aquifer. Recover heat from the geothermal aquifer to supply district heating. Reduce the amount of the future European tax on waste-to-energy emissions.

• A women-led informal waste collection system in Hà Nội
  24 November 2023, by Philippe

  Waste collection and recycling in a city overwhelmed by waste.
  Main highlights of this comprehensive study : 20% of urban waste is collected informally, mainly by women. The informal sector is complex and composed of street collectors, waste deposit managers and recyclers. Recycling practices are highly polluting for the environment and health.

• Open-data on operations
  21 May 2024, by Philippe

  Building trust through public access to environmental and financial data.
  Open-access to financial and environmental data on solid waste management activities ensures transparency. Publishing data on the environmental impact of facilities is a regulatory requirement for all industrial installations. By publishing data in open data format, the open access principle can be respected

• Energy Recovery at Toulouse
  21 May 2024, by Philippe

  Integrated planning across waste, energy and water sectors.
  Tomato production for a competitive price thanks to an innovative concept. Econotre, operated by SUEZ, uses the heat released by incineration of the waste to produce electricity. Low-temperature energy is also recovered to supply heat to greenhouses. The necessary proximity was made possible through integrated land planning.
