The problem

China and southeast Asia are a fast-growing market with an urgent need for effective, large-scale sludge treatment. Urbanisation, changing living patterns and rising living standards are producing huge volumes of organic sludge - and it has to be dealt with reliably, efficiently and at scale.

The climb

From 150 to 800 tonnes a day — the scale keeps rising.
