Tshwane Executive Mayor, Alderman Randall Williams conveyed a congratulatory message to the Wastewater Treatment Division on winning the inaugural Green Economy Change Champion Competition, which centred on innovation and sustainable green technologies that positively impact environmental conservation.
Williams said that the competition which celebrates inspiring examples of green economy innovation at municipal level across the country, was hosted by Green Cape in partnership with the Friedrich Naumann Foundation.
He mentioned that a total of five finalists were selected to showcase their projects and Tshwane came out on top.
“The city’s beneficiation of bio-solids project, which scooped the title, focused on the use of bio-solids produced at wastewater treatment facilities and how this can be turned into a green economy,” Williams said.
He added that the city operates on the premise that conventional sewage sludge disposal options are no longer appropriate and lead to sacrificial land disposal, a constant influx to landfill and uncontrolled spreading on groundwater contamination.
“Some of the winning features of this project is that it has alleviated the city from the financial and environmental impact associated with sewage sludge disposal.”
“Furthermore, it has a high replication potential by extending the model to other wastewater treatment works and has created 23 sustainable employment opportunities,” said Williams.
