Advanced Process Control Minimizes Kraft Mill Effluents
IFAC Proceedings Volumes, 1977 Abstract In recent years the pulp industry, like any other industry, has been obliged to pay more attention to the problem of effluents. For the most part this has been necessary in order to meet legislative requirements; but the chemical and energy losses due to these effluents are in themselves considerable enough to make their minimization ...

Modification of kraft wood-pulp fibre with silica for surface functionalisation [PDF]
, 2008 A new science strategy for natural fibre modification was devised in which glass surface properties would be imparted to wood-derived fibre. The enhancements known from addition of silane reagents to glass fibre–polymer composites could therefore be ...
