    Twinned cities Nice-Vilnius exchange on transport and recycling nutrient-rich waste


     

    -       - A circular approach to nutrient loss

     

    -       _ Designing different roads for different users

     

    These are just some of the ideas discussed during the meeting between Vilnius (Lithuania) and Nice Cote d’Azur (France) as part of the CoM twinning programme 2018-2019.

     

    Waste not want not: closing the gap on nutrient loss

     

    Sewage sludge from wastewater treatment and ash resulting from the burning of biomass are both nutrient-rich waste products with potential for reuse. In Lithuania, a rapid shift from natural gas towards biomass-based district heating sector has greatly increased the volume of leftover biomass ashes. Neither product can be used for growing crops as they contain toxic elements, however, they can be used on biomass plantations.

     

    Under an EU funded project – NutriBiomass4LIFE – Vilnius will create a full-scale self-sustainable closed-loop circular economy model for nutrient-rich waste recycling. Using land that is unsuitable for agriculture, the project will develop a site for woody biomass to be grown and develop a new economically viable business model for this circular nutrient loop! The project hopes to see 27 000 tonnes of dried sewage sludge and 1 500 tonnes of biomass ash recycled in biomass plantations saving 42 000 tonnes of carbon dioxide emissions.

    Waste not want not: closing the gap on nutrient loss

    Did you know? Up to 85% of sewage sludge from Lithuania’s wastewater treatment plants could be processed into dry pellets
