Waste and Climate Change

Articles

  • Climate Change
    24 October 2025, by Pauline

    The waste sector contributes between 3% and 5% of total global Greenhouse Gas (GHG) emissions. Improved prevention and waste management presents an opportunity to reduce global GHG emissions by 15 to 25% when aligned with the principles of Environmentally Sound Management (ESM) — for the protection of the environment and health, and supporting a just and circular transition.
    Globally, the waste sector (including wastewater management) accounts for about 3–5% of global GHG emissions, (…)

  • Green landfill to energy
    24 November 2023, by Philippe

    Integrated infrastructure to replace dumpsites.
    An innovative financing model for waste treatment in developing economies. Produce biomethane, produce electricity. Improve waste management from open dumpsites to environmentally controlled landfills. The case of Meknes, Morocco: 200,000 t/y of waste safely managed; 70% reduction in emissions by 2033; 5,500 MWh/y production capacity.

  • 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.

  • Assessing the GHG emissions of a waste collection and treatment service
    31 October 2025, by Philippe

    GHG assessment, a tool for understanding carbon impact and identifying emission reduction levers.
    Targeted action plan to reduce CO₂ emissions:
    Objective: Achieve a 3% annual reduction in emissions, totaling 16 ktCO2e, broken down as follows: 70% through CO₂ capture and recovery from the WtE plants 8% by improving residents’ sorting habits 7% with a sustainable purchasing policy 7% by expanding the fleet of electric machines 5% by using biofuel for the vehicle fleet

  • Open-burning & Air quality
    24 November 2023, by Philippe

    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.

  • Oil & Gas Waste Recovery
    24 November 2023, by Philippe

    The ecological transformation of the oil industry in the Middle East.
    Hazardous waste treatment at Al Ruways: the largest oil refinery in the Middle East. Maximize resource recovery (water and oil) from oil and gas industrial waste, for reuse on nearby OpCo’s (ADNOC Operational subsidiaries) industrial sites (recovery and reuse of petroleum resources). Increase the green energy production capacity through an upcoming solar power plant.

  • Organic waste recovery
    24 November 2023, by Philippe

    Supporting local authorities to sort, collect and treat domestic food waste.
    Mandatory source separation of organic waste as of January 2024: Collection schemes: on-site composting, door-to-door collection, voluntary deposit Targeting 100 kt/year of biowaste collected in the service area Construction of a methanizer on the river port of Gennevilliers by 2026 to produce biomethane and organic fertilizers

  • CoMétha Pyrogazification Project
    24 November 2023, by Philippe

    A disruptive technology opposing incineration and complementary with methanization.
    From R&D to a full-scale pilot: Treat a mix of organic waste, including food waste and sewage sludge Maximize the transformation of organic matter into syngas Minimize the volume of solid residues (ashes) Recover nutrients (nitrogen and phosphorus)

  • 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.

  • Major waste-to-energy hub
    31 October 2025, by Philippe

    Recovering biomethane and energy from waste produced on the island.
    By 2026, combining multiple technologies to divert 148 kt/year of waste from landfilling: Methanizer producing renewable biogas and soil amendments from biowaste RDF (*Refuse-derived fuel) facility producing local, low carbon energy from waste to replace the use of coal and fossil gas
    Total amount of energy produced : 121 000 MWh/year.
