Resource Conservation

The Nisshinbo Group’s Contributions to the SDGs

The Nisshinbo Group contributes to the achievement of the Sustainable Development Goals (SDGs) through resource conservation activities.
The Group manages key performance indicators (KPIs) as part of systematic measures to achieve its environmental target for improvement of the recycling rate.

Core goals and Targets and the activities of the Nisshinbo Group

The Nisshinbo Group considers SDG 12.5 to be core target. We are promoting resource conservation activities accordingly, as follows.

  • ①Proper disposal of industrial waste through ISO 14001 activities while ensuring proper waste disposal governance
  • ②Promotion of reduction of waste discharge, recycling, reuse of packaging materials, reduction of use, etc.
  • ③Selection and consignment of outstanding waste recycling companies and activities to promote the recycling and reuse of waste at overseas sites where the conditions for waste treatment differ
  • 12. Responsible consumption, production

    Ensure sustainable consumption and production patterns.

  • Targets: 12.5

    By 2030, substantially reduce waste generation through prevention, reduction, recycling and reuse.

Volume of Waste Generated

The Nisshinbo Group generated 55.7 thousand tons of waste, 5% increase from the previous fiscal year. The amount of waste generated per unit of sales was 0.109 t/million yen, 6% decrease from the previous fiscal year. The demand for recovery from the impact of the COVID-19 pandemic led to an increase in waste generated in many operations but a decrease in waste generated per production unit due to an increase in sell.

The recycling rate was 88% (an increase of 3% recycling rate in the previous fiscal year). In the Automobile Brakes Segment, the use of polished powder advanced, and activities to improve recycling rates overseas plants moved forward.

Trends in Volume of Waste Generated by Business and Recycling Rate by Business

The Nisshinbo Group has set the target of achieving a 95 % recycling rate by fiscal 2030. To this end, The Group are engaging in initiatives to reduce the amount of waste generated by each business.

The Automobile Brakes business accounted for 45% of all waste generated by the business. The recycling rate for brake polishing agents at foreign sites greatly advanced.

Examples of the Nisshinbo Group Activities

Reduction of Calcium Fluoride Sludge Emissions by Introduction of Water-expressing Sludge Dehydrator

Nisshinbo Micro Devices Fukuoka Co., Ltd. operates a sludge dehydrator in the fluorine-based wastewater treatment process.

Fluorinated wastewater is treated in a flocculation tank using slaked lime, sulfuric acid, sulfuric acid bands, and a polymer flocculant through a calcium fluoride method and a two-step sedimentation method through a primary and secondary reactor. Finally, calcium fluoride sludge is precipitated on the bottom surface of the sludge sedimentation tanks, and the sludge containing moisture is transported to the sludge dehydrator by a sludge pump. The sludge caked by dewatering treatment (press 0.7 MPa) in the air-milling process is crushed and transported as industrial waste (sludge). The moisture content of industrial waste (sludge) was 65%, and the average transport volume by the end of September was 27 t/month.

The sludge dehydrator used in this treatment process (made in 2007) was judged not to be repaired and used continuously due to deterioration and corrosion of the cabinets and mobile parts of the equipment. As a replacement, the company selected a dehydrator with a water-milling system (1.5 MPa treatment pressure) capable of reducing the moisture content (65% to 60%) and planned an update with a medium-to long-term investment plan in 2019. After the preliminary work in fiscal year 2020, the dehydrator was updated in October 2021, and the water content was confirmed to be 59% based on the start-up evaluation. The operation started at the end of the same month. In November through December, the average amount of transport was 30 t per month.

In the future, the company expects to reduce the volume of sludge transported by 12.5 t per year by optimizing the operation time in accordance with the amount of wastewater, while looking at the sludge treatment status.

Started recycling program for cardboard

Nisshinbo Automotive Manufacturing Inc. (NAMI) in the United States has been to recycling cardboard waste since 2012.

In 2020, the rate of cardboard recycling declined in NAMI due to the impact of Chinese paleopaper import regulations. In 2021, the company launched a recycling program in partnership with Pratt Industries (USA). NAMI introduced compressors for corrugated cardboard to make it easier to carry used corrugated cardboard for the delivery of compressed corrugated cardboard.

NAMI aims to recycle 50 tons of cardboard annually. In 2021, the recycling volume was 42 t, achieving 84% of the target.

Shirt Reproduction Project

Nisshinbo Textile Inc., is working on a project to create and change new shirts from discarded shirts.

Used shirts are collected and cut, and ionic liquids are used to dissolve the cut shirts to extract cellulose. The extracted cellulose is spun and recycled as recycled cellulose fibers. At present, the company is conducting research and development in collaboration with Sinshu University and Nisshinbo Holdings Inc., Business Development Division, and has already successfully spun out high-potency, long cellulose fibers that exceed the current regenerated cellulose fibers at the laboratory level. The ionic liquid used is chosen by Nisshinbo Holdings Inc. and is characterized by no halogen and low risk of environmental contamination.

Technologies will be established in fiscal year 2022, pilot plants will be set up in 2023, and trial production will start in 2024.

Campaign to collect unnecessary shirts

Tokyo Shirts Co., Ltd., recovers clients' unnecessary shirts and use the JEPLAN Recycling Infrastructure of Japanese Environmental Design Co., Ltd., to implement resource circulation.

Bring recovery boxes have been consistently recovered from 10 stores , and all stores have conducted unnecessary shirt recall campaigns four times a year. In fiscal year 2021, campaigns were conducted in March, June, September, and November for a total of 77 days.

As a result, the company collected a total of 30,000 shirts, including not only company products but also other companies’ products. Against the backdrop of the recent increase in environmental awareness, the collection effort has been well received by clients who have struggled to discard clothing products.

During the June campaign, 140 collected shirts, mainly white shirts, were sent to the Yoshinogawa plant of Nisshinbo Textile Inc. from two stores in the Hiroshima area and the Kannabe store for use as raw materials for the Shirt Recycling Project.

Unnecessary shirts recovered in stores are sent to the Kitakyushu Hibikinada plant of JEPLAN, INC., and are sorted and broken down into raw materials. The shirts are then recycled into raw materials using new recycling technologies to make clothing. The materials are also used in motor vehicle interiors, coke oven gases, hydrocarbon oils, cokes, and industrial waste cloth. In the future, the company will consult with JEPLAN, INC., to create a recovery and recycling stream for clothing other than shirts.
