Johannesburg is expanding its dual-fuel Metrobus fleet and will help to grow the bio crops used to produce the fuel.

Delivering his 2014 State of the City Address, Johannesburg’s Executive Mayor, Councillor Mpho Parks Tau, said 150 new buses using dual fuel will be purchased in the coming year and an additional 30 more converted to run on a mixture of compressed natural gas and diesel.

The buses are significantly cleaner than the diesel versions – emitting 90% less carbon emissions into the environment. 

Mayor Tau said the biogas fuel can be sourced from a range of natural products including grass cut by City Parks, biowaste from the Fresh Produce Market and bio crops especially grown for this purpose.

This will also lead to increased entrepreneurial activity and job creation in the agriculture and waste sectors as well as the local manufacturing of the biodigesters which produces the biogas.

These efforts will also extend to other public and private transport. “This will enable all Joburg residents to use locally produced energy sources to power their vehicles enabling them to pay less for fuel or public transport,” said Mayor Tau. 

The diversion of waste away from landfills remains a key priority for the City of Johannesburg. Some of the waste streams identified include the diversion of green waste, builders’ rubble, food waste and residual waste.  

A total of 950 000  City households will eventually be included in the programme which is already being rolled out in Waterval, Zondi, Diepsloot, Orange Farm, Central Camp, Marlboro and Southdale.  

He said the City would partner with the private sector to accelerate the implementation of waste-to energy-projects that will ensure the attainment of a 70% reduction by 2030.
