The plant will have a Materials Recycling Facility (MRF) on the front end to process various waste feedstocks into fuel for both the on-site WtE plant and produce RDF for export. Any useful materials that can be extracted for recycling will be done so at this point, with the residual waste used for fuel.
This will enable the plant to take in a wide range of feedstock waste streams for the manufacturing of refuse derived fuels.
The waste heat from the WtE plant will be utilised in The MRF by using hot air in specifically designed tunnels to dry wet waste streams to make them far more suitable for use in manufacturing reuse derived fuels. This increases the overall efficiency of the WtE facility, with as much of the waste heat used as possible. This has a positive effect on the commercial viability of the facility, by being able to take wet waste other facilities maybe can’t manage, with the additional tonnage come greater gate fees and more income for the facility This heat would have been used in district heating projects in Europe, with many UK facilities unable to use this waste heat.
The feedstock waste will come from a variety of sources:
• MSW direct from Local Authorities and other waste management companies.
• Commercial and Industrial waste from other Waste management companies.
• Processed RDF from other Waste Management facilities.
PMAC Energy will have a capability to procure and supply consistent, quality, feedstocks in both short and long-term contracts to suit our customers, who will be primarily Local Authorities and Waste Management Companies.
Waste plastics contribute to serious environmental and social problems, such as the loss of natural resources, environmental pollution, and depletion of landfill space. Our energy recovery of scrap polymers by thermal methods is well known and environmentally accepted. As plastic becomes a smaller percentage in our waste stream, the PMAC Energy technology will be able to process the lower calorific value of the waste in the future.
Around the globe, environmental, regulatory and economic drivers are, to varying degrees, forcing waste operators to seek alternatives to the traditional method of landfill disposal.
In the UK, the Landfill Tax escalator continues to force waste operators to seek alternatives to landfill, leaving significant quantities of non-recyclable residual municipal and commercial and industrial waste that could be used as feedstock for waste to energy plants.
The reduction in UK landfill capacity, combined with the shortage of waste treatment infrastructure has helped to establish UK RDF export market over 3 million tonnes per annum.
The landmark Paris climate change agreement presents significant international growth opportunities for technologies offering a sustainable and cost-effective method of recovering renewable energy and other valuable materials from waste.
