Toward Realization of a Resource Recycling Society

リード文

We recognize that the realization of a resource recycling society is one of the important items for our business activities, and the Resource Recycling Subcommittee, which is a sub-organization of the Environmental Management Committee, has led the company-wide efforts. Based on the basic policies of "promotion of 4Rs (refuse, reduce, reuse and recycle)" and "selection of materials with reduced environmental impact," the subcommittee has investigated and analyzed the waste generation processes, and examined and evaluated policies for the realization of a resource-recycling society, and reinforced initiatives for a sustainable society through environmental conservation.

Progress Toward Realization of a Resource Recycling Society

Please check here for our goals and progress.

The final landfill rate of industrial waste in FY2020 was 0.2%, and we have continuously achieved zero emissions*1. The total amount of industrial waste increased by 71.9 t compared with the previous year, and the production volume unit increased by 13.2% compared with the 2017 level, both of which did not meet the respective targets. The increase in emissions was mainly due to the removal of unnecessary items in association with the renovation of Minase Research Institute, an increase in highly active wastewater in association with the increase in the production of highly active pharmaceuticals, and the start of operations at the Yamaguchi Plant. The increase in production volume unit was mainly due to an increase in industrial waste output and a decrease in the number of product packages due to standard change of major products (addition of high-volume products).

  • *1 Zero emissions are defined as the percentage of non-recycled waste (sent for landfill disposal or simple incineration) being 1% or less of the total volume of waste.

  • * Special management industrial waste (hazardous waste) is defined under the Waste Management and Public Cleansing Law as waste that has properties of explosiveness, toxicity, infectiousness, and/or possibly causing damage to human health or the living environment. We strive to manage this type of waste properly.

Efforts Toward Realization of a Resource Recycling Society

We have worked to reduce waste generation across the company by reducing paper documents with digitization. We have sold waste paper and metal waste which are no longer needed at our research institutes and production sites as valuable materials, and experimental equipment that is no longer used at the research institutes. In addition, for industrial waste (including specially controlled industrial waste) generated at the research institutes and production sites, we have selected the intermediate treatment contractors that recycle wastes without landfilling.
In pharmaceutical development, we have also started studies using computer simulation technology, which is expected to lead to a reduction in raw materials (waste).
We continue to promote various initiatives and work to realize a resource-recycling society.

Initiatives to promote reduction of environmental impact

Approaches to product packaging

In terms of product packaging, we promote the reduction of its environmental impact by changing packaging materials and forms.
In an effort to reduce the amount of plastic used, previously plastic compartment materials for packaging of injectable solutions were changed to paper-based materials in FY2019, and began distribution in FY2020. In response to the results of a questionnaire survey on product packaging conducted at medical institutions, we have changed the method of binding Blister package sheets for new products from a bag-type (transparent pillow packaging) to a band-type, thereby reducing the amount of plastic used.
In addition, we have switched the inks to be used to vegetable oil inks, as well as changed paper-based materials for individual packaging boxes to FSC®-certified paper. We also verify the quality to further promote the selection of materials that reduce our environmental impact, such as bioplastics.

Major activities Progress
Changing packaging materials from plastics to paper-based materials Changing packaging materials for parts of products. Started distribution of the products in FY2020.
Reconsideration and changing the method of binding Blister package sheets(Adopting the band-type) Started distribution of 2 products in FY2020.(A total of 7 products as of the end of March 2021)
Switching individual packaging box materials to FSC®-certified paper. Started distribution of 8 products in FY2020.
Selecting vegetable oil inks. Started distribution of 4 products in FY2020.

In addition, pursuant to the Containers and Packaging Recycling Law, some of the containers and packaging materials for the products we sell are recycled.

Plastic 161.5 35.1
Paper 198.1 1.4

Other efforts

Introduction of paper files

We have introduced paper-based files since January 2020. By switching some plastic files to paper files, we are able to reduce the amount of plastic used.

Use of photocopy paper or purchase of stationary materials

For photocopies, we perform print management, and a cloud storage system "BOX", which was introduced globally in October 2017, promoted paperless storage and reduced the amount of work required to store and share files. As for purchasing, we have indicated in an easy-to-understand manner whether the products listed in the purchasing system are in compliance with the “Act on Promotion of Procurement of Eco-Friendly Goods and Services by the State and Other Entities” and promoted awareness within us so that each employee has environmental awareness.
