Electra Greentech is delivering a DBOT (Design-Build-Operate-Transfer) project for a sludge drying facility at Shafdan, in partnership with Electra Infrastructure and Electra Concessions. Shafdan is the largest wastewater treatment plant of its kind in the Middle East, serving the greater Tel Aviv metropolitan area. Currently, it produces sanitary sludge containing approximately 80% liquids, typically used for agricultural purposes. The new facility will operate on natural gas and utilize advanced belt dryer technology to produce dry sludge with approximately 10% moisture content. The facility will include: Four belt drying units Wastewater pumps Odor treatment systems Storage areas Additional supporting infrastructure The resulting dry sludge has significantly reduced volume, enabling more efficient storage and transportation. Its high nutrient content makes it a valuable resource for agriculture, biogas production, and as an alternative fuel source. Under current Israeli regulations, dry sludge (classified as Type A) is designated for agricultural use, thermal energy generation, and landfill applications.
“An advanced sludge drying facility transforms an operational by-product into a valuable resource—reducing volume, optimizing logistics, and delivering significant cost savings.”
