Landfill disposal is the last option in sustainable waste management, but it does remain necessary for waste flows that cannot be put to beneficial use or treated thermally. Indaver makes sure that such disposal is carried out safely. The waste in our landfills is a link in our waste-to-energy chain, however, because we recover methane from it, which we can use to generate energy.
- There is a category 1 landfill in Antwerp. Hazardous waste and residues from the incineration and/or treatment of waste are disposed of in this landfill.
- There are category 1 and category 2 landfills in Doel. The category 2 landfill is for inorganic and non-hazardous waste with a low content of organic-biodegradable substances.
- The Hooge Maey site in Antwerp is a category 2 landfill for non-hazardous municipal and comparable industrial waste. These waste products are not qualified for recycling or thermal treatment with energy recovery.
Indaver rigorously guards the environmental safety of its landfills. An electronic leak-detection system checks whether the soil is sufficiently protected against infiltration of waste. Indaver ensures that there are sufficient financial reserves for the final capping and for aftercare when the landfill site is no longer in use.
Landfills: sources of biogas
The Hooge Maey landfill site in Antwerp directs all its efforts to the energy valorization of the landfill gas. Since 2004, biogas has been recovered from bio-organic residual waste at the Hooge Maey facility. Four engines generate energy for approx. 4,800 households.
Sustainable approach to space
Indaver handles space economically and sustainably. Indaver needs additional landfilling capacity, however the Flemish region does not allow for it, therefore Indaver identified an innovative solution. The lowland that lays between the 3 landfills (landfill category 1 Antwerp, the landfill of the Hooge Maey and the landfill of the dewatering project Amoras) was converted into a new landfill and named ‘the 3 valleys’.
