Policy on Paper Recycling

Paper recycling is an important initiative, through which we make effective use of resources and contribute to the environment as well.

1)Target
The Oji Group aims to achieve a rate of use of recovered paper of 65% by FY2020, which is part of the Environmental Action Plan of the Japan Paper Association. For this purpose, we promote the collection of waste paper as the material to expand the use of recovered paper further.

2)Performance
n FY2017, the Oji Group used around 4 million tons of waste paper. The rate of use of recovered paper was 64%.


Coverage: Oji Paper, Oji Materia, Oji F-Tex, and Oji Nepia

The Oji Group produces a wide variety of paper and paperboard products. We use recovered paper differently depending on the required quality of each product.


(1)Containerboard

Containerboard is the collective name for liner paper used for the surfaces of corrugated containers and wavy corrugated medium sandwiched between the surfaces. Recovered corrugated containers, magazine recovered paper, and other kinds of recovered paper constitute more than 90% of the materials of containerboard, which may be called a leading recycled product.


(2)Boxboard

Boxboard is used mainly for boxes for boxed tissues and confectionery. Although it looks like a single sheet of paper, it actually consists of multiple layers, as shown in the photograph. It is made by layering five to as many as nine pulp sheets. By using different kinds of recovered paper pulp from layer to layer, we increase the ratio of pulp with a lower environmental impact during production and promote the effective use of recovered paper.



(3)Printing paper

Printing paper is used as copying paper and for magazines and various other printed materials. While the use of recovered paper for this product is difficult due to quality constraints, we are promoting the use of recovered newspaper and magazine recovered paper for making printing paper.


(4)Newsprint

In the Oji Group, the second largest amount of recovered paper is used for this product, following containerboard. Higher-quality newsprint is demanded due to the advancement of newspaper printing technologies. We are working on the further improvement of recovered paper pulp as the material of newsprint.


The amount of waste paper generated in Japan has been decreasing due to changes in consumer needs, such as the digitalization of information media. To increase the rate of use of recovered paper further, we take initiatives in many fields, including the use of confidential documents and difficult-to-process waste paper and encouraging our industry to improve the quality of recovered paper. The quality improvement of recovered paper is essential for better recycling. We are striving to achieve appropriate segregation to prevent the inclusion of prohibited materials* that are inappropriate as papermaking materials.

*1 Prohibited materials A: Materials whose inclusion causes serious defects

Stones, glass, metal, earth and sand, wood, cloth, plastic, synthetic paper, nonwoven cloth, disposable diapers, scented paper, dirty paper, sublimation transfer paper, thermal expansion paper, waxed corrugated containers, and others

  • Sublimation transfer paper: Paper for sublimation printing. This type of paper is reused as fillers for bags, shoes, and similar goods. In many cases, this paper is combined with materials as recovered paper.
  • Thermal expansion paper: This type of paper is used mainly for Braille printing. It is special paper, on which characters, etc. stand out three-dimensionally when the paper is heated.
  • Waxed corrugated containers: Corrugated containers that are made waterproof with a wax coating

Prohibited materials B: Materials whose inclusion should be avoided

Carbon paper, carbonless paper, resin-coated paper, laminated paper, sticky tape, thermal paper, colored paper, advertising inserts, samples as supplements of magazines, and similar paper

   
Segregated recovered paper Segregation management at a paper mill


Waste paper recycling system in Japan is unique in the world. In this system, waste paper is segregated into corrugated containers, newsprint, magazines, and others in households, municipal governments, supermarkets, offices, and other places where it is generated, before it is transported to paper mills via recycling service operators or wholesalers. On the other hand, recovered paper is distributed all over the world as an international commodity. Above all, demand for waste paper is growing in Asia.

The Japan Paper Association provides training workshops on paper recycling in Asia in a project commissioned by the Ministry of Economy, Trade and Industry. The Oji Group cooperates with these workshops by introducing its paper recycling system to trainees, including people from governments, paper manufacturers, and wastepaper wholesalers of each country. We assist with the workshops with tours of paper mills and other activities. Building a paper recycling system in each country is important for ensuring the stable supply, demand, and quality of recovered paper. The Oji Group will contribute to the development of paper recycling systems in the Asian region.
