Unisphere Waste Conversion Ltd. has completed negotiations on a 10-year agreement with Finnish waste recycling firm Metso Corp. for exclusive North American rights to Metso's patented tire pyrolysis system.
That technology is scheduled to be included in Unisphere's first pyrolysis facility, scheduled for completion at Belledune, New Brunswick, in November 2003, said Unisphere Technical Director Bruce Jank.
The agreement-covering engineering, procurement, construction and manufacturing for the Metso pyrolysis system-will be in effect once Metso and Unisphere complete the legal text and Unisphere signs its first purchase order from Metso.
Unisphere has its own pyrolysis technology, but the company decided to put that ``in mothballs'' and go with Metso's process instead, Mr. Jank said.
``We went with Metso because of their reverse engineering in further development of the technology,'' he said. ``They looked at the deficiencies in previous systems and designed around those deficiencies.''
Mr. Jank declined to elaborate, saying the Metso system is proprietary, but added that the system's improvements are mainly in the feed and withdrawal processes.
Plant construction at Belledune won't begin until the spring of 2003 because of the harsh climate there, Mr. Jank said.
