Effective Resources Utilization(Paper Recycling)

紙のリサイクルの考え方

Fundamental Policies

Paper Recycling is an important initiative for making effective use of resources and making environmental contributions as well.
The Oji Group aims for “promotion of paper collection and further expansion of waste paper usage” in accordance with the basic policy of the Oji Group Environmental Charter.


Oji Group Paper Recycling Results

The Oji Group uses approximately 4.08 million tons of waste paper each year, the largest amount and about 24% of the 17 million tons of total waste paper use in Japan. The breakdown of waste paper use by the Group is as follows: about 50% waste corrugated containers and about 20% each of waste newspaper and waste magazines. In addition, waste paper usage ratio(※1) in FY2018 was 64%, an increase of 2.5 points in the past 10 years as a result of various efforts to use waste paper as a resource.
The Oji Group seeks to achieve a recovered paper use rate of 65% by FY2020, which is part of the Environmental Action Plan of the Japan Paper Association. To this end, the Group promotes the collection of waste paper as a raw material to expand the use of recovered paper further.
※1 Waste paper usage ratio = Volume of recovered paper/Total volume of fibrous raw material (total consumption of waste paper, wood pulp, and other fibrous raw material)

Reducing Environmental Impact by Promoting Waste Paper Recycling

Paper is a material that is highly suitable for recycling, and therefore, it is important that paper be reused (paper recycling) rather than disposed of as waste. Paper (wastepaper) recycling contributes to (i) securing stable supplies of papermaking raw materials, (ii) effective utilization of resources, (iii) sustainable use of forest resources, and (iv) reduction of waste.
Following a period of rapid economic growth, there is a period when waste becomes an environmental problem. To address this issue, government, trade organizations, and the papermaking industry cooperated to build sorting, collection, and recycling mechanisms that led to the current wastepaper recycling system. In 2018, the combined wastepaper recycling rate for paper and paperboard was 64.3% and the collection rate was 81.5%, putting Japan at the highest levels in the world.

Various Measures to Promote the Use of Wastepaper

The Oji Group is working to promote various uses of waste paper, such as thorough sorting of waste paper at offices and factories within the group, a used paper wholesaler as a supplier, and an awareness campaign on paper recycling in cooperation with local residents and industry groups.

1)Enhancing the quality of wastepaper

The inclusion within wastepaper of specially processed paper and foreign substances that are not suitable as papermaking materials (collectively referred to as prohibited materials) is a cause of product problems. It is necessary that such prohibited materials be excluded before collection. Accordingly, the Group cooperates with wastepaper dealers, who play a central role in wastepaper logistics, to eliminate prohibited materials included in wastepaper discarded by households and businesses and strives to raise the wastepaper use rate and manufacture high-quality paper products.

2)Increasing the use of waste paper

  • Use of difficult-to-process paper: The Group is installing specialpurpose facilities to process paper tubes, laminated paper, and other difficult-to-process paper for use as a raw material.
  • Use of confidential documents: In consideration of the maintenance of confidentiality and issues of information leaks, confidential documents were incinerated in the past, but the Group performs confidential dissolution processing in fully secure facilities for use as a raw material.

International Trends in Waste Paper Recycling

China is the world’s largest importer of wastepaper, importing 17.03 million tons in 2018. Imports come from North America, the EU, and Japan, which shipped 2.75 million tons, approximately 20% of the total, to China. In conjunction with the tightening of environmental regulations, China has announced a policy of banning the import of all solid waste including wastepaper starting at the end of 2020. As a result, the global wastepaper supply and demand will enter a period of major change.
The Oji Group is deepening collaboration with wastepaper dealers, who play a major role in wastepaper recycling, to stabilize procurement prices while maintaining and stabilizing waste paper recycling systems.
