Dynamic simulation aids recycling plant redesign   Share Print

great interest in North America in increasing paper recycling
capacity. The enthusiasm to produce, combined with lack of
experience with an emerging industry, led some to rush plant
designs before they were fully vetted. At the time, there was a
lot of speculation as to what it would take to produce high-
quality recycled pulp.  Several of the mills built during the
period have since closed. The reasons for their failure include
poor design, poor water management, high energy consumption and
high raw material cost due to the increased demand for waste
paper. Our recycle mill in Northampton Pa. was one of those ill-
fated plants. In 2001, the mill was purchased by Belkorp
Industries Inc. and renamed Newstech PA, LP.  Newstech PA, is a
deinking pulp mill with a design capacity of 420 air-dry metric
tons/day. Our engineering group has been tasked with studying
the redesign and feasibility of
