BUDGET: € 60.000
On behalf of the OVAM, Ecorem was assigned to follow-up a pilot case executed on a former landfill, located in Zuienkerke, Flanders. Within this case study some technical tests were carried out on the excavated waste material to investigate the possibilities for a waste to resource conversion. The performance of both on site and off site techniques were evaluated. These tests also contribute to the mapping part of OVAM’s research programme on ELFM and revealed more information on the composition of former landfills dating from different era’s.
In order to recover as many materials as possible, five contractors were assigned to perform separation tests on the bulk material from the Zuienkerke landfill. All used techniques were described, resulting in a separate flow sheet for every contractor. The resulting fractions and materials were described in detail to obtain an inventory of the bulk material. Based on the characteristics from the obtained fractions, all possible valorisation pathways are listed, suggesting a Waste to Material (WtM) or a Waste to Energy (WtE) valorisation pathway. Fractions that needed further treatment were also discussed.
