  1. 1. Converting Waste to Energy. Improving Social and Environmental Resilience. Going Zero to Landfill.
  2. 2. NEW HORIZONS WASTE TO ENERGY Collectively, com m unities are increasing earth’s waste burden. There is also a growing need for energy consum ption. And we create a circular econom y which offsets the collective carbon footprint and the com m u n it y’s reliance on finite, expensive fossil fuels. Add a state-of- the-art biogas plant. Which converts non- hazardous waste into clean, environmentally- considerate, low-carbon energy. Provides an alternative energy resource. Using the latest technology disrupt waste management in South Africa.
  3. 3. Client truck unload mixed Municipal Solid Waste(MSW) and Wet Trade Waste (WTW) in the main tipping hall. At a separate entrance, trucks deliver and dump pure organic waste (POW) Pow is loaded into an organic press which separates organics from solid waste and liquefies the organic material The organic material is pumped into the suspension buffer tank and after analysis, pumped into the digesters, where it is digested by bacteria to produce biogas through anaerobic digestions. The biogas, captured at the top of the digester, is pumped to the biogas upgrade plant The biogas is cleaned dried and then enters the separation plant for separation into Biomethane (CBM) and Co2 Liquid CO2 is pumped into storage tans and collected by tanker trucks, while Biomethane is compressed odorized and stored into tank trailers, which are collected regularly ORGANIC EXTRUDER PRESS SUSPENSION BUFFER TANK CBM BIOGAS POW
  4. 4. Client truck unload mixed Municipal Solid Waste(MSW) and Wet Trade Waste (WTW) in the main tipping hall. At a separate entrance, trucks deliver and dump pure organic waste (POW) Pow is loaded into an organic press which separates organics from solid waste and liquefies the organic material The organic material is pumped into the suspension buffer tank and after analysis, pumped into the digesters, where it is digested by bacteria to produce biogas through anaerobic digestions. The biogas, captured at the top of the digester, is pumped to the biogas upgrade plant The digestate, from the digester, is sent to a centrigue to separate and solid and liquid material and solid as an organic fertilizer POW ORGANIC EXTRUDER PRESS SUSPENSION BUFFER TANK ANEROBIC DIGESTER DIGESTATE CENTRIFUGE FERTILISER
  5. 5. MSW WTW Client truck unload mixed Municipal Solid Waste(MSW) and Wet Trade Waste (WTW) in the main tipping hall. At a separate entrance, trucks deliver and dump pure organic waste (POW) BULK WASTE SORTING ROLLER SCREEN RECYCALBE SORTING PLATFORM ANEROBIC DIGESTER ORGANIC EXTRUDER PRESS SUSPENSION BUFFER TANK MSW and WTW are loaded onto conveyor belts, undesired material is removed ,plastic bags are mechanically opened and the waste is separated by size Larger items are transported to the manual sorting platform, for waste pickers to extract as much recyclable waste as possible Smaller items are transported to main press after metal items have been removed/ The press squeezes any organic material out of waste
  6. 6. MSW WTW Client truck unload mixed Municipal Solid Waste(MSW) and Wet Trade Waste (WTW) in the main tipping hall. At a separate entrance, trucks deliver and dump pure organic waste (POW) BULK WASTE SORTING ROLLER SCREEN ORGANIC EXTRUDER PRESS MSW and WTW are loaded onto conveyor belts, undesired material is removed ,plastic bags are mechanically opened and the waste is separated by size Smaller items are transported to main press after metal items have been removed/ The press squeezes any organic material out of waste SCREEN FINES & HEAVY FRACTION WRAPPERBALER After mechanical separation, the RDF is baled and wrapped for dispatch
  7. 7. 2 Days BUFFER BIOGAS Biogas to upgrade plant (1,250 Nm3/hr) Sludge from press Compost Centrate Recirculate Spent digestate Separator BIOGAS PROCESS 17-25 Days DIGESTER
  8. 8. THE FIRST WASTE-TO-ENERGY FACILITY OF ITS KIND IN AFRICA
  9. 9. Planning a WtE project • Resource • Detailed resource assessment. Building a WtE plant is like planning a mine. • Contracting • Municipal Contracting limitations • Private Resource Contracting • Technology Choices • Do not limit the tech choices • Energy Flows • Environmental • SA Environmental Legislation is complex
