Thandaza Waste Solutions: A Greener Future

tws_logo

There are Substantial Energy Resources in Waste Recycling

World Wide Environmental Issues: 
Consequences of  the Environmental Issues: 
Some Principal Culprits in Environmental Issues: 
  1. Greenhouse Gas Emissions
  2. Water Pollution
  3. Air Pollution
  4. Soil Contamination
  5. Food Chain Toxicity
  1. Environmental Destruction
  2. Disease
  3. Starvation
  4. Contamination of water pockets
  1. Landfill
  2. Water Management
  3. Demand for Electricity
  4. Contamination of water pockets
  5. Sewage discharge

Landfill Issues: Landfill Solutions:
  1. Land Pollution Legacy
  2. Leaching of Toxins to Water Table
  3. Rodents and Disease
  4. Methane ‘Farming’
  1. Sort and Gasify Waste
  2. No Landfill
  3. No Leachate
  4. Controlled Emissions
  5. Generate Electricity
  6. Create jobs

Water Management Issues: Poor Water Management Consequences: 
Water Management Solutions:
  1. Sewage Discharge
  2. Shortage of Potable Water
  3. Landfill Leachate
  4. Sanitation
  1. Infected Potable Water
  2. Agriculture  Destruction
  3. Animal Destruction
  4. Fish Destruction
  1. Sewage
  2. Concentrate Solids
  3. Bio Digest Concentrate
  4. Generate Power
  5. Use Digested Sludge as Organic             
  6. Fertiliser OR as Fuel for 
  7. Electricity Generation


The process involves sorting to remove inert materials – concrete, glass and metals - and then  through a pyrolytic and plasma process producing a synthetic gas (syngas). This gas is used to generate steam, drive turbines and turn electrical generators.
Each 10000 tonnes of landfill waste will generate 1.25 MWe (electrical power) and 2.75 MWTh (thermal energy) all for export

The system will also deal with tyres, medical waste and contaminants such as asbestos.

 

Sewage Solutions:

  1. Existing procedures are cumbersome and produce large quantities of sludge. The sludge is benign but its disposal is difficult.
  2. Sewage rich in gas and nutrients.
  3. Current practice makes use on neither.


Environmental Benefits:

  1. fewer CO2 emissions
  2. reduced consumption of fossil fuels
  3. reduced total energy input
  4. production of sustainable electricity from a waste product
  5. beneficial use of the treated biosolids as a fertiliser when applied directly to land, negating the need for disposal to landfil or incineration which would produce further CO2 emissions
  6. has negligible odour impact
  7. more sustainable than carrent sludge drying process.


The TWS proposals deal with the 3 culprits as described. In summary:

  1. Landfill is eliminated.
  2. Water contamination is eliminated.
  3. Electrical power is generated.
  4. Thermal energy is created as a bonus.
  5. NEW JOBS ARE CREATED

Can we afford not to adopt this type of proposal?
