By adjusting the process of mechanical pulp, Swedish producers can save one terawatt hours of electricity, shows a thesis by Lisbeth Hellström at Mid Sweden University.
Swedish paper industry consumes 5 – 6 terrawatt hours of electricity per year to produce mechanical pulp. By adjusting the process of chipping logs, energy consumption can be reduced up to twenty percent, making the producers save both energy and money.
- If the electrical efficiency and production efficiency are implemented in full scale, it means big profits for the industry. A plant, that’s producing 500 000 tonnes of mechanical pulp, can reduce energy costs by between 40 and 80 million per year, says Lisbeth Hellström.
In her thesis, “On the Wood Chipping Process - A Study on Basic Mechanisms in Order to Optimize Chip Properties for Pulping”, she says that the quality of mechanical pulp preserves or even improves.
