The SBS System

This page provides a brief introduction to the technology that we offer so if you want further information please don’t hesitate to contact us.

The name SBS stands for Soil Bio-Stimulation. The SBS Mass Treatment system revolves around the safe use of aerobic bio-degradation (Mother Nature’s own way of recycling most of her resources).

How it works

Our machine uses high pressure air (over one bar) to provide the means necessary to accelerate the degradation process safely and economically. This offers a far better way of reducing waste in both mass and volume, as the natural process is accelerated by these artificial means.

In the case of municipal waste, the objective is to degrade and then dry the materials sufficiently to allow segregation of the organic and inorganic entities (cans, bottles and plastic cartons) so that they may be recycled or composted.

What it can achieve

The latest calculations suggest that due to shorter digestion periods and increased capacity (due to increased plant height), such in-vessel technology could increase the productivity of existing composting sites by as much a 5,000 percent.

This 50-fold increase in productivity of existing sites could often be obtained through better use of the land arising from a combination of increased plant height and much reduced process time; typically 14 days.

An SBS system 15 metres high would process approximately 88 tonnes of green waste per square metre per year, whilst many windrow systems will process approximately 2 – 2.5 tonnes of green waste per square metre per year.

• The SBS forced air process is silent, the process inherently odourless and the treatment effective. Human contact, dust and noise nuisance from the segregation process would be avoided by proper enclosure.
• It can emit more energy than it consumes.

• Given that organic waste is calculated to be 68% of household waste flow it is calculated that it should be possible to recycle 87% of collected household waste with no bio-degradable waste being sent to landfill.
• A wide range of organic wastes from many sources including agriculture, horse racing, food processing and possibly the fishing industry could be dealt with in a similar manner.

• The plant is wholly enclosed and does not exhibit a chimney.
• It is relatively cheap to build occupying a much smaller footprint (tonne for tonne) than traditional windrow or tunnel composting.
• The system can be fully automated with remote monitoring and management of multiple silos and sites.

• Units could be designed to fit inside existing industrial buildings only 6 metres high. Commercial treatment vessels would be of greater diameter and up to 20 metres high.
