The Autoclaving Process

Process Overview

Arrival of waste.

Reception of unsorted waste. There will be an inspection and manual extraction of oversized items.

Steam Treatment.

Automatic loading of autoclave with 20 tonnes of unsorted MSW.

Post Treatment Separation.

Screening out the Wilson Fiber® from other collected sale products by automatic and/or manual methods.

Fiber output.

The fiber is screened and when required can be dried and refined. Wilson Fiber® (renewable fuel) is then sold/used for renewable power generation.

Energy Production

The Wilson Fiber® has a high surface area to volume ratio and medium calorific value resulting in easy conversion to power and heat via a variety of methods:

  • Co-Firing with coal in existing power plant furnaces.
  • Combustion on its own as a solid fuel in conventional furnaces.
  • Gasification to produce synthesis gas (Syngas).
  • Pyrolysis to produce hydrogen and methane.
  • Anaerobic digestion to create high yields of methane and a high quality soil enhancer
  • Production of Bio-Butanol and Bio-Ethanol by breaking down the predominantly cellulosic fibre to sugars we can produce bio-butanol, acetone and ethanol for traditional markets such as plastics, solvents, pharmaceuticals or for the second generation biofuels market.


Totally modular in design to accept various volumes of waste. A Wilson System® consists of two autoclave vessels which treats 20 tons of waste per hour.

1 Module:    150,000 tpa capacity

2 Modules:  300,000 tpa capacity

3 Modules:  450,000 tpa capacity

  • Reduce waste up to 80% of its original volume
  • Does not require pre-sorting at the source
  • Diverts up to 90% of waste from landfill
  • Can be configured for high labour content or semi-automatic
  • Small footprint (circa 160m by 40m for 1 module system)
  • Clean operating environment
  • Maximum recycling of water usage
  • Can be fossil fuel independent
