Recycling & Gasification

Hunsdon Skips Waste Disposal do everything in their power to recycle as much of the industrial and domestic waste that they collect.

One example of the way that we do this is with all wood that is collected. We send all the wood waste we collect to 1st London Power where it is recycled and turned into wood chippings or animal bedding. The process 1st London Power use is called Stein Gasification Process. Below are some basic principles about the Stein Gasification Process and why it truly represents an answer for the future.

  • Stein Gasification is a pure pyrolosis process. As there is no oxygen present, nothing burns and no dioxins are created.
  • As there is no oxygen involved in the process, materials remain in their elemental form, which means chlorine cannot be converted into a dioxin, for example. Without oxygen, dioxins cannot be generated.
  • There is no gas dilution, which means that you can start with the highest calorific value gas and can achieve the cleanest possible gas pyrolosis. This makes running an engine easier as it does not need to be adjusted or require special parts. No gas dilution.
  • As no pollutants are generated, there is no need to spend time, effort and energy in dealing with them or mitigating their impacts.
  • Char, a by-product of the process, is basically charcoal (carbon and ash), a clean-burning material, which is why people use it for BBQs.
  • 100% of the gas is available for the engine, which improves its efficiency.
  • The only by-product of the process is vitrified slag, a non-leaching and inert material that is usable by the construction industry as an aggregate.

The Stein Gasifier
A variety of waste products can be used as fuel in the Stein Gasifier Process including crops, tyres, wood-chips, sewage sludge, bio-fuels, industrial waste and municipal solid waste (MSW).
The feedstock is shredded to a size of about 15mm so that rapid heating of the fuel core can be achieved. Air and oxygen are removed prior to the material being fed at a constant rate into the gasifier retort where the conversion process takes place.
