Wakefield Project is being completed by the Shanks Group PLC, UK, a successor to the Babcock group. Estech began its autoclave business in 1998, and built its first full scale demonstration (single vessel system) in Sheffield UK. This is identified as the Model 1 system, and is now on display at Estech's headquarters in Ohio. A full size twin vessel facility, Model 2, was built in 2000 and operated in Bridgend, Wales. Recognizing the existing deficiencies in autoclave systems, Estech reviewed the worldwide state of the art of autoclave and other emerging waste technologies, assembled an engineering group with a broad background in technology development (from NASA, DoD, etc.) and privately funded a multi-million investment in improvements to produce its vessel-based Model 3 system. Others, including the UK, have determined that autoclave technology is the best solution for municipal waste management. The Model 3 system is built around its high-throughput autoclave/dryer (FiberCycle), which has been realized and demonstrated in numerous vessels. Recognizing the need for a proper path of utilization of the volumes of "fluff" produced, Estech developed early on an integrated electric/steam system to use the fluff as fuel. There are significant advantages to the use of a Brayton cycle engine, although other engines are also used. The resultant PowerCycle produces steam and commercial electricity from the dried/cleansed biomass. WaterCycle captures, cleans, and reuses water. Post-vessel separations cull out ferrous, non-ferrous, and plastic goods for commercial sale. The system is being commercialized globally. Much of combined equipment is available off-the-shelf, but the assembly has proprietary and specialized technological improvements. Estech is now finishing the construction of a proprietary Model-3 unit for a specialty municipal waste stream in the EU. Because of Estech's lead in the field, images of its autoclaves have been used by other companies in their advertisements. While Estech actively exercises its proprietary rights, those who contemplate systems promised on the basis of Estech's images should be aware that valid offerers would be showing their own images. Sterecycle claims to be the first company in the world to build and operate a full scale autoclave plant for household waste. In late 2005 the company started construction of the first vessel for their industrial scale autoclave plant to process household waste. Under contract from 3 local authorities, the Sterecycle plant has been in full commercial operation in Yorkshire, England since June 2008 (but for a period of shut-down
