Evaluation of algal treatment options for olive mill wastewater to produce energy and biofertilizer 

The conventional olive mill wastewater (OMW) treatment methods adopted in Tunisia are either costly or ineffective,causing environmental pollution. This project is aimed at developing an eco-friendly and cost-effective microalgal-based process for olive mill waste treatment and recycling. Such a process should result in the production of (1) treated and reusable OMW for ferti-irrigation use, contributing to resolving the water scarcity problem; (2) renewable biomass useful for clean energy production, particularly bio gas; and (3) bio-fertilizers for agricultural use, using the process by-products, bio char and sludge.
