Sludge incineration
Encyclopedia
Sludge incineration is a process for generating thermal energy
from sewage treatment
plants. The process is in operation in Germany
where Klärschlammverbrennung GmbH in Hamburg
incinerates 1.3m tonnes of sludge
annually. The process has also been trialed in China
, where it has been qualified as an environmental investment project. However the energy balance of the process is not high, as sludge needs drying before incinerating

Incineration
Incineration is a waste treatment process that involves the combustion of organic substances contained in waste materials. Incineration and other high temperature waste treatment systems are described as "thermal treatment". Incineration of waste materials converts the waste into ash, flue gas, and...
