The impacts of biological invasions
Biological Reviews, EarlyView.ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Revisiting acidulation for tall oil and lignin manufacturing
The Canadian Journal of Chemical Engineering, EarlyView.Abstract Tall oil is a byproduct of the kraft pulping process when softwood is used as raw material. As the production of softwood‐based pulp is in high demand, the optimization of the tall oil production process needs to be revisited to ensure the highest quality and quantity of tall oil manufacturing. In this work, the process for tall oil production

Kraft Cooking with Addition of Reducing Agent
JAPAN TAPPI JOURNAL, 1966 The changes of polysaccharides during ordinary and two per cent sodium borohydride added kraft cooking of Shirakaba birch were studied. The cooking cycle was divided in five stages, in each stage the changes of polysaccharide from wood residue (pulp) and cooking liquor were observed.The effects of borohydride addition to yield of pulp were considerably
