Sewage Sludges

Sewage Sludges

Half of the organic materials used for nutrition are released into the environment by humans and animals.

Advanced biological treatment facilities established by municipalities prevent sludge in sewage systems from merging into the seas or rivers and enable the collection of this sludge. Even though authorities have preformed extensive research for various solutions related to the disposal of these sludges, which exist in large amounts, there is still no reliable solution proven to be non-destructive for the environment.

Biogas facilites struggle to render some parts of this organic content useful and encounter various difficulties caused by the structure of the sludge. The leading factor is that Sludge has a high moisture content.

Sludges are not able to be burnt directly, because of high moisture content. They are dried using energy, and then are burned.

In the meantime, all organic materials contained herein are converted into carbon dioxide or water and released into the environment, causing global warming.

Also another disposal method, a burning process in cement plants not only has increased disposal cost, but also started to be considered as an undesired method by factories due to its negative effects to the quality of the cement.
