Pulp Production Process
A recycling-driven production system constructed to reuse resources with the most up-to-date equipment
UKP that Hyogo Pulp manufactures is of high purity and strength, thanks to the Kraft process in which wood chips are treated with chemicals under high heat and pressure.
Eighty percent of the raw materials comes from residual wood and scrap wood such as timber offcuts from lumber mills, as well as recycled wood from dismantled homes. The remailing 20 percent comes from virgin low-quality woods that are not suitable for construction.
In the manufacturing process, pulp digestion waste liquid is concentrated at 75 percent or higher to effectively use wood resources with minimum waste. The concentrated liquor is then incinerated in a high-efficiency recovery boiler to generate more power in-house than consumed internally, using a high output turbine. The excess power output is supplied to a power utility company, allowing the Company to contribute to the local community.
The Company uses wood chips as its main raw materials. These raw materials include residual wood and scrap wood such as timber offcuts from lumber mills, as well as recycled wood from dismantled homes. These materials account for 90 percent of the total volume used.
Additionally, chips from virgin wood procured from forest thinning are used. Looking ahead, the Company plans to secure raw materials by taking advantage of its geographical location, while aggressively tackling environmental problems by continuing to effectively use precious wood resources in the evolving recycling-based society.
