The GrahamTek Waste-to-Energy Technology

The GrahamTek Waste-to-Energy technology recycles hydrocarbon based waste streams. It is designed and is able to process General and Hazardous waste. The primary applications is to process plastic waste and waste tyres to extract products such as gas, oil and carbon black. This treatment process of waste into usable products reduces the reliance on fossil fuels and natural resources and at the same time reduce the impact of un-degradable waste that are harmful to the environment.

  • The technology is a patented process of thermal mechanical cracking where the long carbon chains in the carbon waste are divided into smaller carbon chains, which changes the physical attributes of the waste.
  • Carbon containing general waste is inserted into a reactor chamber and is decomposed under heat creating a vapour in the absence of oxygen and any chemical catalysts. There is no combustion or incineration of the waste. The vapour is condensed where the carbon chain is “cracked” through a mechanical process that is part of the uniqueness of the technology and a significant part of the Intellectual Property that resides in this technology.
  • The vapour forms a synthetic gas or SYNGAS that is converted into furnace or marine gas oil as it passes through the condensers. The furnace oils can be further converted into diesel that meet the SANS 342 standard quality and will be an energy source that will reduce reliance on fossil fuels.
  • The technology is a closed loop system designed for zero emissions throughout the process with a series of scrubbers and condensers ensuring no hazardous gases, ash or other hazardous materials are released from the system. 
  • The Plant has a minimal processing footprint of 500 Square Meters under roof and a further 500 Square Meters to sort and process the incoming waste and the residue waste from the process. It requires roughly a total of 1 000 Square Meters or 11 000 Square Feet of operating space.
  • The plant can recycle up to 20 tonnes of waste per day or 400 tonnes per month, which produces on average 200 000 litres of oil and 100 tonnes of carbon black per month.
  • The plant has several built in safety features including fire, pressure, flow rates, and mechanical stoppage. In addition the plant functions completely off-grid and has been designed to put power back into the grid. 
  • There is minimal noise pollution, the major noise emanating from the plant is a 4kw motor for power generation on site. The generator removes the reliance on external power and is an additional safety feature. Additional safety is provided through the global 24x7 remote management of the system by GrahamTek operations in Cape Town South Africa.
