Rottneros to Invest SEK 90 Million to Close Water Loop at Vallvik Mill
Dec. 16, 2010 - Rottneros said that it has decided to invest SEK 90 million (approx. USD13.18 million) in closing the water loops in the bleaching plant at its Vallvik Mill in Sweden.
Closing the water loops is the final part of an upgrade program to increase the mill's pulp making capacity.
The closure of the bleaching plant also will significantly reduce the mill's water usage, along with a slight reduction in the cost of power and chemicals, Rottneros said.
In addition, and as a result of the project, the biological external water purification plant that is currently being built can be kept significantly smaller.
As a result of the upgrade program at Vallvik, the mill's capacity will increase by 20 percent — from 200,000 tpy to 240,000 tpy of sulphate pulp.
Rottneros noted that the current production permit for the mill is limited to 220,000 tpy and a request for a temporary extended permit for 242,000 tpy has already been submitted to the relevant environmental authorities.
