<b>Weyerhaeuser Installs Optical Sorting System in Denver</B>

Weyerhaeuser Recycling installed a PaperSort system, geared to sort materials optically at its Denver, Colorado, recycling facility.

The technology is specifically designed to handle, identify and separate paper grades for recycling.

PaperSort can sort mixed loads of recovered paper into distinct product streams using the unique ``MultiGrade Sensor'' technology and a proprietary mechanical system design.

Denver was chosen as the second Weyerhaeuser recycling facility for the PaperSort system. The first system was installed in Baltimore in 1999 and has been in full operation ever since. PaperSort is the result of five years of development work by Weyerhaeuser Co. and MSS, Inc. MSS, based in Nashville, Tenn., has been a manufacturer of automated sorting equipment for the materials recovery industry for over 28 years.

``With the trend toward commingled or single stream collection in the residential waste market, PaperSort enables us to get a more uniform, cleaner, more economically viable supply of recovered paper from the `urban forest','' said Mark Starnes, vice president of Weyerhaeuser's recycling business. ``A higher quality sort allows our mills to make better quality recycled content paper more economically.'' Weyerhaeuser has been a world leader in recycling paper and forest products since 1974.

``PaperSort represents a tectonic shift in sorting technology, including Internet connectivity, and is fully programmable to meet specific customer, supplier or mill requirements,'' said Garry Kenny, president of MSS. ``Our results show that a recycling plant can recoup its initial investment within three to four years, based on lower labor costs and greater margins.''

The PaperSort system is available to other recovered paper processing companies and to mills making recycled content paper. Automated Sorting Technology LLC is a joint venture formed by Weyerhaeuser and MSS to design and build PaperSort® systems for any company or organization which can benefit from the technology.
