LONDON, England — DS Smith, a leader in sustainable packaging solutions, has unveiled a £48 million investment in a new fibre preparation line (F-line) at their Kemsley paper mill. Forming part of DS Smith’s organic investment program, this multi-year investment will deliver attractive returns through improved efficiency and reduced costs. Kemsley is the largest mill for recycled papers in the UK, and the second largest in Europe. It produces 830,000T of paper every year, all made from 100% recycled fibre. The new line will supply recycled fibre to PM3, which is a highly versatile paper machine, that is capable of producing white top test liner, plasterboard liner and other corrugated case materials grades.
