HyClone of Logan, Utah, offers disposable bio-process containers made from polyethylene that can replace stainless steel mix tanks.

``The containers cost a few hundred dollars compared to as high as $50,000'' for the tank, said product manager Kurt Christoffersen. ``The system allows you to take a nonhomogeneous product, let it settle over three to four months and remix it into a product ready for dispensing.''

HyClone, which employs 350 worldwide, is a subsidiary of Sweden's Perstorp AG.
