We provide liquid paper cartons and environmentally friendly packaging materials, which help reduce CO₂ emissions and the consumption of plastics derived from fossil resources, in accordance with brand owners' needs.
By investing in overseas companies and M&A activities, we are upgrading and expanding our paper packaging materials to meet the de-plasticization-related demand. These materials include liquid paper cartons featuring high recyclability, soft packaging materials made from barrier paper that can also be used for food packaging, and high-quality pulp-mold packages featuring strength and aesthetic qualities.

• Environmentally friendly products

Aiming to establish a circular economy, we are implementing a material recycling initiative to recycle used paper packages (paper cups and aseptic carton packages).
Generally, paper packages are a composite of layers of plastics, aluminum, and other materials with the paper materials to give the packages water resistance and barrier properties. Most of these packages are therefore incinerated after use as unrecyclable products.
In response, Oji Group built a system for recycling paper fiber (pulp) by collecting the used paper packages and eliminating any contaminants and the plastic and aluminum layers from them through shredding and washing processes.
The paper fiber recovered in this way is recycled into corrugated containers, hand towels, and other products and utilized effectively.

• Cases of paper packaging recycling

To build a foundation for our packaging business, we acquired Walki Holding Oy, a Finnish company engaged in the processing and manufacturing of sustainable packaging materials in April 2024.
Walki's mainstay core products are paper-based environmentally friendly packaging materials featuring boththat combine recyclability and barrier properties. The company is distinguished by its high profitable in the European market, where environmental regulations are becoming increasingly stringent.The company boasts high profitability in Europe, a market where environmental regulations are increasingly strict. We will further strengthen the Group’s business foundation as a global supplier to meet the worldwide demand for conversion to sustainable packaging materials.

We are proceeding with the development of biomanufacturing technologies that use wood resources as raw materials.
In particular, we are focused on sugar solutions, which are a key substance for various types of biomanufacturing processes,^*1 ethanol that can be used to manufacture SAF^*2 and other chemicals, and polylactic acid which is a representative biomass plastic. To establish technologies for manufacturing these substances, we will accelerate initiatives for their social implementation, including the installation of a pilot plant for manufacturing sugar solutions and ethanol and the Biomanufacturing Ecosystem Construction Project Using Wood and Other Under-Utilized Resources, which was selected as a NEDO project.

• *1 Manufacturing processes with the goal of eliminating dependence on petroleum resources. A feature of these processes is their use of biomass-derived sugar as a raw material and microbes with an enhanced ability to produce functional materials (smart cells)
• *2 Sustainable aviation fuel: Fuel seen as a last resort for the decarbonization of the aviation industry

Cellulose Nanofiber (CNF) and cellulose products from Oji Holdings are produced by fibrillating wood fibers (pulp).
The fiber fibrillating process enables them to have outstanding functionality despite being biomass materials, including high transparency, high viscosity and high strength. Because of these properties, they are expected to have many applications in a wide range of industrial fields, including automobiles and other transportation equipment, electronics and chemical products.

Information about CNF and cellulose products, including their properties and example applications, are available on the product information page.

Japan is dependent on imports for much of the licorice consumed domestically. This has also led to resource depletion and environmental conservation issues associated with the harvesting of wild licorice.
In addition, there is the risk that export restrictions will be implemented or other problems will occur. Therefore, there is demand for domestically produced licorice. We cultivate licorice in Japan to guarantee high-level traceability and be ready to support safe, reliable and sustainable businesses.
We process our licorice as requested by customers, thereby expanding its use into the fields of pharmaceuticals, cosmetics, and food products.

Oji Pharma was established in 2020 for R&D and commercialization of medicinal products made from sulfated hemicellulose. This substance is obtained from hemicellulose, a by-product of pulp production.
Sulfated hemicellulose from Oji Pharma is unique because it is derived from wood, in addition to its anti-inflammatory and anti-coagulant properties.
Possessing the benefits of safety, reliability, and stable supply that are unique to wood-derived products, sulfated hemicellulose has the potential to replace animal-derived pharmaceutical products such as heparin.
