Tech innovation

The plant features advanced technology that not only treats 43,000 m3 of leachate and wastewater per year effectively but also achieves a remarkable water recovery rate of 80-90%. This means that a substantial portion of the treated water can be reused, contributing to water conservation efforts in the region.

Key features include the ability to treat various liquid waste types, bespoke pre-treatment processes, and advanced filtration systems. Moreover, by exceeding the safe discharge limits set by the South African Department of Water and Sanitation, the plant ensures that the treated water meets stringent environmental standards, mitigating the risks posed by liquid waste to water resources and public health.

“We are extremely proud of this innovation. It align to the Group’s sustainability strategy of water reduction, biodiversity preservation and circular economy thinking but addresses the pressing need for effective liquid waste treatment while setting a precedent for sustainable practices within the industry,” said Jason McNeil, CEO of Interwaste.
