Rubbish to resource
The idea of rubbish to resource is not a new one. The saying “one man’s rubbish, is another man’s gold” has been around for generations. Now more than ever we need to utilise rubbish as a resource, if not to save money, to save our planet!
Our facility north of Horsham is designed to take waste that would otherwise have been destined for landfill and turn it into fuel, energy and a nutrient rich soil enhancer.
The organic parts of the waste (food scraps etc.) are separated out and sent to anaerobic digestion tanks to be broken down by bacteria. This process is explained in detail on Our Facility page. The main product from this biological breakdown process is biogas.
Biogas is mainly made up of methane [70%] (the gas used in gas hobs), and carbon dioxide [30%] (the gas humans exhale). This biogas is removed from the tanks and used as a fuel on-site in combined heat and power engines. At full capacity we produce up to 4.5MW of power from the gas, the equivalent power use of 10,000 homes! We also use the heat produced from the engines to pasteurise and dry our compost-like output.
Refuse Derived Fuel (RDF)
RDF is an output from the MBT facility mainly comprised of a mixture of paper, plastics and cardboard. When combusted the RDF gives off energy and can be used as a fuel in energy recovery facilities to produce electricity.
The anaerobic digestion process works in a similar way to composting; just without oxygen. After the bacteria has had its fill in the anaerobic digester tanks, a compost-like material remains. The compost-like material is dewatered and a drier can reduce the volume of this material further by removing more moisture. The water is put back into the system to be used again.
The end product is dry with a high nutrient content.
Our facility has Animal By-Products Regulation (ABPR) accreditation which means the compost-like output can be used as a restoration soil.
For detailed information on how we process your waste to produce each of these outputs, read more about the mechanical workings and production stages at Our Facility.
The MBT facility uses magnetic separators to remove metals (ferrous and non-ferrous) that remain in the ‘black bag’ waste and this is sent for recycling. Typically, the process captures in excess of 75% of the metals that remain in the waste processed through the MBT facility.
