Recycling and Green Energy

The sterecycle® process results in the following sterile products :

1. Non-organics - clean with labels / foodstuffs etc removed

aluminium cans
steel cans
plastics
wood
aggregates
glass

2. Organic biomass fibre - this clean material has many possible uses.

Organic Fibre

The organic fibre can be used as a soil conditioner. Alternatively, sterefibre® can be further used in several other ways:

Green Energy
The fibre is a clean high biomass fuel and can be used to produce energy and/or heat. The biomass fibre is an ideal feedstock since it is a homogenous material that can be efficiently fed into a power plant. Unlike “mass burn incineration” or "gasification" which destroy the entire black bag, including plastics, the energy derived from sterefibre is truly green, being derived from the waste food and paper which are renewable sources like biomass.

Bio-Gas
The fibre can also be passed through an Anaerobic Digester to produce both a clean biogas for green energy generation and a soil conditioner. The fibre is an ideal feedstock for Anaerobic Digestion since it is a homogenous material unlike the original complex untreated waste.

Bio-Ethanol
sterefibre® is potentially a low-cost feedstock for "second generation" lignocellulosic bio-ethanol, with much of the mechanical degradation of the waste feedstock already performed by the autoclave process. Whilst cellulosic bio-ethanol technologies are not yet commercial, they remain an important potential end market.

Paper Pulp Recovery
Passing the fibre through a washing plant will seperate out the long fibres, 60%, that can be sold to the paper industry as a high quality paper/card pulp. The remaining short fibres, 40%, can be used in other processes described here.

Construction Products
The fibre can be used for making a multitude of construction products that use cellulose based materials (eg. fibre board or tiles).
