Thermochar Waste Heat Recovery System

We conducted a feasibility study regarding the design of a waste heat recovery system to supply power for a series of char plants. The waste heat from the plant is used to power the rankine cycle which ultimately produces the electricity needs of the entire plant, approximately 500kW. This makes the plant resistant to electricity shortages and allows it to be installed in remote areas without the need for a power supply.

Bio-Energy Feasibility Study


Western Cape Landfill Gas Study – Grey Green engineers assisted Austrian Waste-to-Energy company RAB to conduct a feasibility study on Western Cape landfill sites. The project comprised a technical and economic feasibility analysis to assess the energy generation potential at selected sites to aid RAB in their decision to set up plants in South Africa.
