Vilka alternativ finns till deponering : En plockanalys av deponifraktion från återvinningscentral

Today, a large part of the recycling facilities inert waste goes to landfill. Landfilling with waste leads to greenhouse gasemissions and the accumulation of pollutants that are liable to leak into the surrounding environment. Water and waste expertise in Norr AB (Vakin) is responsible for all waste management in the municipality of Umeå and Vindeln and aims to climb up the waste hierarchy by finding ways to recycle landfill waste. Today 100% of the landfill fraction is deposited. The purpose of the study is to investigate alternative treatment methods of waste in a landfill fraction, to reduce the amount of landfill waste. A sorting analysis was performed at Dåva landfill and waste facility in Umeå AB (Dåva DAC) to investigate the waste content in a landfill fraction. Interview questions were sent via e-mail to communal recycling centers to compare the handling and content of the required landfill fraction. The result show that landfill fraction contained hazardous waste, glass, porcelain, concrete, plasterboard/insulation, metal, combustible/plastic, brick, stone, tile/clinker and cardboard. To recycle construction and demolition waste, the fraction must be uniform and free of extraneous material The conclusion is that concrete, tile/clinker, brick and stone are sub-fractions that have the greatest potential for recycling. With a better waste sorting at the recycling facility, the amount of landfill fraction can be reduced
