TORONTO (October 12, 2010) – An advanced technology at a plant under construction in Sault Ste. Marie will extract oil from used tires, along with other valuable by-products, when it becomes operational early next year.

The showcase facility will be using a proprietary technology developed by Environmental Waste International Inc. (stock symbol EWS on the TSX Venture Exchange). Its patented microwave delivery system breaks down the tires at the molecular level, reducing them to their simplest forms – oil, carbon black, steel and hydrocarbon gases.

Running at a planned recycling rate of about 300,000 tires a year, the plant would produce some 240,000 U.S. gallons of oil, 2 million pounds of carbon black, and 600,000 pounds of steel annually. Off-gases produced by the system will be used to co-generate electricity that allows the system to be energy self-sufficient.

Reverse Polymerization™, the patented EWS technology used in this system, is the most advanced process of its kind in the world. Since it does not melt tires, but rather breaks apart the molecular bonds, virtually 100-percent of the tires’ by-products are reclaimed.

Stephen Simms, President and CEO of EWS, says the facility in the Sault will be the first large-scale pilot plant of the tire application. “There’s a tremendous amount of interest in our process,” he notes, “with many potential purchasers eager to see the system up and running.”

Securing raw materials for the plant is already under way. Approximately 12 million used tires are generated in Ontario each year. In fact, under the Ontario Tire Stewardship program, a fee is paid for every tire processed through the plant.

Ellsin Environmental Ltd., the owner of the Sault facility, contracted EWS to design and build the prototype equipment for the plant which will have a total cost in excess of $6 million.

Simms points out that some 300 million used tires are generated each year in North America, and another 600 million annually in other parts of the world. He says the company’s goal is to capture about 30 per cent of the global market over the next decade.

The prototype EWS system being installed in the Sault is the TR-900. Models to be sold in the future will be larger. For example, the TR-6000 – the largest unit that EWS currently has on the drawing board – is designed to process 2 million used tires a year and costs about $30 million.

Each TR-6000 will be capable of reclaiming over 1.6 million gallons of oil, about 6,500 tonnes of carbon black, and 1,800 tonnes of steel a year. Operations are expected to begin in the first quarter of 2011.

In North America, used tires are currently ground up and used in such applications as carpet under-padding or road re-surfacing, burned in cement kilns and other energy generating facilities, or they are sent to landfill.

“Our technology squeezes every bit of recyclable product out of a tire, and does so without sending any hazardous emissions up a smokestack or residual waste to landfill,” Simms explains.

After finally being completed and ready for use in July this year, Hawaii County’s Hilo recycling center has not received a single bag of trash to be sorted.

Mayor Billy Kenoi said the sort station won’t be used “for the original purpose it was built and designed for before I took office.” He said the facility will still become a “valuable tool” for use in diverting waste from the landfill, but that he has no intention of trucking garbage to West Hawaii.
Since its conception in 2003, the project has undergone several redesigns aimed at adjusting the price tag and operational costs. While those changes were delaying completion, a new county mayor and administration took office.
Built on a 5-acre site across from the county’s greenwaste-collection area, the 20,000-square-foot sort station was to be the first stop for East Hawaii’s rubbish. Items were to be removed for recycling, reuse and on-site composting to extend the life of the Hilo landfill. The remaining rubbish was be trucked to the Puuanahulu dump located near Waikoloa.

“Plans are being drawn up to maximize the full use of the sort station,” Kenoi said. He expects to decide in the next “few months” how best to utilize the sort station.
While pursuing the project, the county was able to extend the life of the Hilo landfill, one of two on the island, by steepening the sides to create more space.

According to Waste Business Journal (WBJ), construction and demolition debris (C&D) waste volume for 2010 is showing signs of improvement or at least is falling more slowly than last year’s decline of 20% from the year before. Preliminary WBJ statistics indicate that C&D waste volume for 2010 will be down between 8% and 10%. WBJ estimates that the US will generate 104 million tons of C&D waste in 2010, down from 114.6 mil. tons in 2009 and 143 mil. tons in 2007. On the bright side, new processing facilities augmented by improved processes has improved the overall recycling rate to 28%, up from 23% in 2001. Higher disposal fees at landfills in recent years has created an incentive to recycle more as well. That leaves 75 mil. tons for disposal, of which 36 mil. tons will go to C&D landfills and about 31 mil. tons will go to sanitary landfills, which either have C&D only cells or are simply the more convenient option. The remaining 8.5 mil. tons will go to waste-to-energy plants or industrial boilers.
