Marex provides complex solutions for waste management including sludge fermentation and biogas production.
Sludge fermentation is a proven process of sludge stabilization dating back to the end of the 19th century with the added benefit of biogas production which can be used as a energy source. Sludge fermentation is an optimal process for the treatment plants of a big capacity or high load concentration because of the high efficiency of the process in comparison to the different stabilization methods.
