Asahi Kasei Medical will construct a new plant for the spinning of cellulose hollow-fiber membranes for Planova virus removal filters in Nobeoka, Miyazaki, Japan, increasing annual production capacity by 40,000 m2/year upon completion in May 2019.
Chiyoda/Japan — Virus removal filters are used to enhance safety in the production process for biotherapeutic products such as biopharmaceuticals and plasma derivatives. Asahi Kasei Medical has been producing Planova cellulose membrane filters, which were launched in 1989 as the world's first filters developed specifically for removing viruses from biotherapeutic products, and Planova Bio EX hydrophilic PVDF (polyvinylidene fluoride) membrane filters, which provide superior viral clearance in high protein concentration solutions.
With heightened standards throughout the world for the viral safety of biotherapeutics and advances in the development of monoclonal antibodies and other biopharmaceuticals, the company expects global demand for Planova filters to continue growing.
With its new spinning plan, the manufacturer wants to maintain stable product supply and meet rising demand. Together with a spinning plant for Planova Bio EX filters completed in Oita, Japan, in 2016, the new spinning plant will increase the company's total capacity for hollow-fiber virus removal membranes to 130,000 m2/year.
