C Green

C Green is transforming sludge into local organic fertilizer according to FAO guidelines by using a special process for the treatment.

Field: Water Technology and Sanitation
Solution: Local Organic Fertilizer
Stage of Development: Prototype Development


Many waste-water plants were installed in Lebanon in order to treat sewage water, yet the solid part of the sewage, the sludge remains one of the most dangerous wastes affecting our environment after being randomly discarded in the sea and rivers.

C Green is transforming the sludge into a 100% local organic fertilizer by using a special process for the treatment and by following FAO guidelines. The treated sludge will then be used in agriculture and landscaping.
