Weyerhaeuser to Tackle Skyrocketing Fuel
Vancouver, British Columbia, Canada, 08 May 2006 -- /PRNewswire/ -- Nexterra Energy Corp. announced today that it has signed an agreement with Weyerhaeuser's Kamloops cellulose fiber mill and Paprican, the Pulp and Paper Research Institute of Canada, to verify the application of Nexterra's innovative gasification technology for pulp mill lime kilns.

Nexterra's gasifier enables mill operators to significantly reduce fuel costs by converting boilers, kilns, and dryers from natural gas to "syngas" - a clean, low-cost biofuel produced by gasifying wood residue.

"Reducing our fuel costs is a strategic priority for Weyerhaeuser, so we're excited to be working with Nexterra and Paprican on a potential gasification solution for our lime kilns," said Bill Adams, manufacturing services manager at the Weyerhaeuser Kamloops Mill. "Over the past decade we have significantly decreased our reliance on fossil fuels. Nexterra's gasification technology shows tremendous potential as a clean, cost-effective solution to lower energy costs in our kraft mills and moves us closer to energy self-sufficiency. This agreement allows us to take a closer look at how the gasifier would perform in our mill before making a decision to acquire the technology."

Adams said that the Nexterra gasifier system has the potential to reduce greenhouse gas emissions at the Kamloops mill by 25,000 metric tons per year. The 60 million Btu/hour gasification system would displace the equivalent amount of natural gas needed to heat 4000 residential homes.

North America's pulp and paper industry consumes 900 trillion Btu of natural gas and fuel oil each year at a cost of USD 8.0 billion. There are 150 kraft pulp mills in North America, each consuming millions of dollars of natural gas or fuel oil in their lime kilns. Since the mid-1990s, the cost of natural gas has increased by 500%, leaving North America with some of the highest natural gas prices in the world and placing severe competitive pressures on North American forest companies.

"We are very pleased to be a partner in this project," said Mike Towers, senior research engineer at Paprican. "Rising energy costs continue to be a major challenge for the pulp and paper industry, and lime kilns are major consumers of fossil fuels. Developing alternative fuel systems, such as Nexterra's gasification technology, is essential for the industry to remain competitive. We are confident that this project will demonstrate an attractive option for substituting fossil fuels in lime kilns and achieving critical cost reductions."

"Firing lime kilns with syngas is a natural extension of our gasification technology and represents a significant new market opportunity for Nexterra," said Jonathan Rhone, Nexterra president and CEO. "We are very pleased to collaborate with Weyerhaeuser and Paprican, both of whom have well-established track records of innovation, as well as the commitment and technical capabilities needed to make this project a success."

About Nexterra Energy Corp.

Nexterra Energy Corp. develops and manufactures biomass gasification systems that convert solid fuels into clean, low-cost heat, and power. Nexterra systems enable customers who self-generate energy, such as the forest industry and institutional users, to produce energy using residual or waste fuels produced on-site. This results in lower energy costs and less reliance on natural gas and grid-purchased electricity. In April 2005, Tolko Industries Ltd. purchased a multi-million dollar Nexterra gasification system for its plywood plant near Kamloops, British Columbia. In November 2005, Nexterra sold a system to U.S. multinational Johnson Controls Inc. as a key component in a USD 16 million biomass cogeneration plant that JCI is supplying to the University of South Carolina.
