70MW of heat that is normally lost to the atmosphere because there are very few industrial facilities that have sufficient CHP demands for large-scale efw. “Small-scale facilities such as Energos’ facilities in
Norway and its UK sites, scheduled to open in 2014, can supply usable amounts of energy (up to 20MW of heat) to local customers. Apart from the efficiency benefits, such plants also qualify as a ‘recovery’ plant under the EU Waste Framework Directive and stand to benefit from the UK’s Renewable Heat Obligation. He continued: “Another approach is to provide
a new commercial or residential development with an efw plant to meet its carbon neutral requirements and satisfy planning conditions. Energos is partnering with UK developers to integrate local waste treatment infrastructure with low carbon energy supply for such developments,” he said.
Since 2002, Energos’ Forus advanced thermal processing facility in Stavanger, Norway, has operated at high efficiency to provide electricity into the local grid and hot water into a district heating system for an adjacent industrial and commercial estate. Te 40,000 tonnes per annum EfW plant exists at the heart of the community, handling municipal and commercial waste and complementing local recycling facilities. Te Energos patented gasification technology, an
advanced thermal conversion technique, was developed in Norway during the early 1990s in conjunction with the University of Trondheim. In Europe, Energos offers a proven and commercially viable gasification technology capable of generating renewable energy from household waste and post- recycling residue. It offers a clean energy recovery from waste solution that provides a best practice alternative to mass-burn incineration and a commercially proven and bankable alternative to landfill. Te company has more than 500,000 hours of operating hours over more than 15 years at eight plants across Europe. Te Energos process converts residual, non-

recyclable waste into a gas by using the heat of partial combustion to free hydrogen and carbon in the waste. Residual waste is fed into the gasification chamber, where it is converted into a syngas. Tis syngas is then transferred to a secondary oxidation chamber where it is mixed with air and recycled flue gas under tightly controlled conditions that ensures complete and efficient combustion resulting in reduced emissions in the flue gases. Te upshot is ultra-low emissions that outperform EU Emissions Standard (2000/76/EC), with the resulting heat recovered to produce steam and/or electricity.
