Construction work for the new 140,000 tpy pulp mill in the USA has started. Columbia Pulp wants to produce pulp based on straw.
US company Columbia Pulp has started construction of its straw pulp mill in the north-western states of the USA. The ceremony for the official start of construction work was held at the end of September. A mill with a capacity of 140,000 tpy of market pulp is being set up on a site of more than 180 ha. The product is apparently going to be sold to various converters in the north-western states of the USA and serve as a substitute for unbleached hardwood pulp.
Pulp will be made from straw from wheat and alfalfa, which is said to be available "in abundance" at the location in one of the main wheat cultivation regions in North America. "The purpose of the mill is to manufacture high-quality bulk and speciality pulp for direct sale to paper and packaging producers as an alternative to wood-based pulp," said Columbia Pulp.
According to the company, the quality specifications are as good as or better than those of hardwood pulp and recovered paper pulp. Besides market pulp, the mill will apparently also be selling a variety of by-products such as lignin and sugar.
