Sludge digestion

Anaerobic digestion reduces the weight (dry matter) of sludge. Digestion also aims to stabilise the organic matter in order to reduce olfactory nuisances and to produce recoverable energy in the form of biogas.


To reduce the quantity of sludge and produce energy

Faced with the rise in the production of sludge and the increasing difficulty in eliminating it (costs, regulations), SUEZ implements techniques that reduce the volume of the sludge and recover biogas.


Developing innovative technologies for sludge digestion

SUEZ can offer proven processes that are constantly improved and that effectively meet your need to digest the sludge produced by the treatment of wastewater.
