Energy Presentations

1. Converting Waste to Energy.
Improving Social and
Environmental Resilience.
Going Zero to Landfill.

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. 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
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

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
