The sewage sludge is the residual semi-solid material left from industrial,water treatment or wastewater treatment processes.The treated form of sewage sludge also called "Biosolids".Anyone have any idea on reuse it
in the commercial way?I heard that this material can turn into organic fertilizer,bricks,or burn in the incinerator.The processed sludge is odorless.
Please share with me.

The sludge from the sewage treatment plant can be used as fertilizer.
The sewage sludge of the sewage treatment plant is rich in organic matter and humus, which is the first choice for making ecological fertilizer. The specific manufacturing process mainly includes two steps of removing heavy metal and drying.
Sludge from sewage treatment plants contains more organic matter. When there are less heavy metals, it can also be used directly as fertilizer. However, fertilizers for vegetables and food are not recommended.
Fertilizers made from sludge from sewage treatment plants can be used as fertilizers for fertilizers or fruit trees, tea trees, and green trees.
