The Oji Group contributes to the realization of a sustainable society by addressing environmental problems through diverse business activities.
Development of Biodegradable Plastics and Paper Products with Added Functions as Environmentally Friendly Projects
Recent years have seen growing global demand for plastic replacements. The Oji Group, having been manufacturing base paper for food use, will develop biodegradable plastics as plastic replacements and paper products with enhanced functions, with the leading role played by the Packaging Promotion Center (established on April 1, 2018).
We are developing plastic pellets that combine pulp with polylactic acid, a biodegradable plastic
Packaging material with barrier properties
We have developed a recyclable packaging material with barrier properties against steam and oxygen, which will enable packaging materials, most of which are plastics at present, to be replaced with paper.
Traveler lid for paper cups
We have developed a paper lid made from recyclable, biodegradable pulp in response to the fact that the majority of lids are plastic.
We have also begun sample distribution of base paper that is appropriate for manufacturing paper straws.

Oji Group’s Paper Products That Can Replace Plastic Products
Base Paper for Paper containers
Made from fresh pulp only, this paper features high purity and low odor levels. It is available in a wide range of thicknesses, from 140 to 450 g/m2. In addition, it is available as coated paper, which ensures higher printing effects, and as neutral paper, which can be used for a wide variety of food containers, such as ones for ice cream and yogurt. (Oji F-Tex Co., Ltd.)
OK Rain Guard
This product is water-repellent paper for printing, which was developed based on woodfree paper.
Made from 100% natural pulp, it is an environmentally friendly product.
This paper is used for the labels of envelopes and perishable foods, exterior packaging paper, golf score cards, and other purposes. It has unlimited potential applications. (Oji F-Tex Co., Ltd.)
SEPAFREE® (liner-free adhesive label)
This is a series of environmentally friendly labels, which are waste-free because they do not have release paper. They are available as two-fold labels or in the form of a pad or roll upon request. They are used for a broad range of applications in a number of fields, such as logistics, municipal governments, and novelties.(New Tac Kasei Co., Ltd.)
Paper envelopes with mesh paper as buffer
Use of these envelopes for home delivery services permits acceptance of goods via home delivery boxes, mailboxes, or similar items, thereby reducing redeliveries. In addition, these envelopes are made of paper, with even the buffer being made from paper, which reduces dependence on plastics.(Oji Tac Co., Ltd.)
Green Wrap, the Recyclable, Moisture-proof Packaging Paper
Green Wrap is packaging paper that is mainly used to prevent copying paper from being exposed to moisture.
Unlike polyethylene-laminated moisture-proof packaging paper, which is disposed of as industrial waste, Green Wrap is an environmentally friendly packaging material that can be recycled and reused.
Used by numerous customers since its launch, this product meets the increasing demand for non-plastic products.

Water Environment Business
The Oji Group provides water treatment systems that are appropriate for a variety of water environments by leveraging its expertise in water production and wastewater treatment that have been accumulated through paper manufacturing technologies it has cultivated for many years and combining them with a range of needs. With technologies and a system that enable us to conduct appropriate on-site surveys, water quality analyses, and laboratory tests, we have so far introduced our proprietary water treatment systems in systems for eliminating cadmium from industrial wastewater, and industrial water production equipment at an industrial estate in Thailand, etc.
We will continue striving to disseminate water treatment systems while advancing the technological innovation, thereby contributing to the development of water environments in Japan as well as overseas, including Southeast Asia.

Energy Business with its Focus on Biomass Power Generation
The existing biomass power plants have been operating without any problems, and the joint venture power generation business with Mitsubishi Paper Mills is planned to commence operation in 2019. Revamp of our existing hydroelectric power plants have also been making steady progress. As for the power retailing business, the power retailing company which we established jointly with ITOCHU ENEX has continued to perform strongly. In addition, we are also expanding our biomass fuel business in line with the expansion of our energy business. For example, Hakodate-Hokuto Oji Forest & Products, a fuel chip company which makes effectively use of unused domestic forest resources, was established in November 2018 (Hokuto City, Hokkaido).
