Perpetual aftercare

When a landfill site is sealed, the waste body is wrapped up like a watertight parcel. As a result, all the processes going on in that parcel of waste are gradually brought to a halt. These processes can start up again, however, if the surface sealing springs a leak. This gives rise to the need for perpetual aftercare of the seal.

Perpetual aftercare does not comply with the principles of sustainable development. Perpetual aftercare can be avoided by enhanced stabilisation and/or clever selection of waste materials. This should create a situation where in the absence of aftercare the landfill no longer poses a threat to human health and the environment. A promising technique!
