Environmental Business and R&D

環境ビジネスと研究開発

Oji Group has been tackling environmental issues through diverse business activities, and contributing to the creation of a sustainable society.
In addition, we use LCA (Life Cycle Analysis) in product or system design for reducing the environmental burden and CO2 emissions from the procurement of raw materials to manufacturing, sales, use, and disposal. We supply a variety of environmentally friendly products and systems to society.

Eco-Friendly Material Development Initiatives

The Oji Group is developing eco-friendly materials to address the issue of plastic in the ocean, a global scale problem, and to contribute the reduction of CO2 emissions as a measure to fight global warming. By developing paper materials that can take the places of plastic packaging and biomass plastic materials made from renewable forest resources, the Group seeks to contribute to the development of a sustainable society.

Development of paper materials as alternative to plastic packaging
Development of multi-barrier paper

The Oji Group developed SILBIO※ BARRIER, a multibarrier paper made from a paper base with a barrier coating layer, using its water-based coating technologies, one of the Group’s areas of specialization. The barrier coating layer prevents water vapor, oxygen, and other substances from passing through, curtailing deterioration of the content and maintaining aroma and moisture content.
※ SILBIO=SILVA+BIOREFINERY
Silva means forest in Latin. The name was coined to incorporate the intent to create eco-friendly products that enrich society using biorefinery technology from forests.


SILBIO Barrier was presented at a G20 Summit (held in Karuizawa-machi, Nagano Prefecture on June 15 and 16, 2019) ministerial meeting as an innovative initiative from Japan.

Development of biomass plastic raw materials

Biodegradable plastics have been the subject of considerable attention in recent years, and much of the sugar used as a raw material is produced from sugarcane or corn. There are concerns that sugar produced from edible resources will result in food competition in relation to global food supply shortages.
The Oji Group is researching the production of sugar by breaking down wood components (cellulose) using enzymes through the application of technologies acquired from bioethanol research.
The aim is to supply sugar derived from nonedible sources as a new raw material for the production of biodegradable plastics, demand for which will increase in the future.

Development of Pulp Composites

By mixing pulp into biodegradable plastic, various properties including strength and rigidity can be improved. The Group is conducting research as a means of expanding applications for biodegradable plastics.


Examples of processed pulp composite materials

Development of biomass plastic film

Biomass-derived plastic films are expected to be used for food packaging and an expanding range of other applications in the future.The Oji Group has commenced development of distinctive biomass plastic films through the application of thin film stretch processing technology accumulated in the development of capacitor films.。

Development of pulp-made Traveler lid

We developed the Traveler lid, a lid made from pulp that is both recyclable and biodegradable, while plastic lids are currently the norm. The interior of the paper cup is laminated with polylactic acid, a biodegradable plastic, and both the lid and cup can be composted.
Oji Fibre Solutions started distributing the lids in New Zealand and Australia a few years ago and is now developing products for the Japanese market.

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.

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.
