Ground-deployed concentrating solar field for municipal sludge drying

This ground-mounted thermosolar installation provides heat to a large municipal sludge dryer in Arizona, taking advantage of the region’s abundant solar resources. Traditionally, municipal sludge is sent to landfills; however, this innovative system sterilizes the sludge using renewable energy, converting it into a valuable fertilizer. By harnessing concentrated solar thermal energy, the process exemplifies state-of-the-art waste treatment techniques, reducing environmental impact and promoting sustainability.
