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 medium-term 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 a total of 59,400 tons of waste during the fiscal year, down 2% YoY after adjustments*. Waste generated per sales amounted to 0.117 tons per million yen, down 1% year-on-year (YoY) after adjustments*. This difference resulted from an increase in the amount of waste generated in the textile business.

In the textiles business, the amount of waste generated (wastewater sludge) increased due to stricter wastewater standards, but the Group as a whole saw a slight year-on-year decrease after adjustment.

The recycling rate was 82% (an increase of 3% from the adjusted recycling rate in the previous consolidated fiscal year*). New thermal recycling plants were established in China, South Korea, and Thailand, and efforts were made to improve the recycling rates at overseas sites.

* Effective from the previous consolidated fiscal year, we have changed the fiscal year-end from March 31 to December 31. As a result, the previous consolidated fiscal year, which is the transitional period, was an irregular fiscal year. For this reason, the rate of year-on-year change in actual results is not stated. Instead, when comparing the fiscal year under review with the previous fiscal year, for reference purposes, we state the rate of increase/decrease in waste generated and waste generated per unit of sales from the same period of the previous fiscal year, adjusted to be the same 12-month period as in the consolidated fiscal year under review, to the consolidated fiscal year under review.

* The drop in the recycling rate for the chemicals business in fiscal 2017 was due to routine repairs at the Company's recycling and disposal contractor. In fiscal 2019 the Electronics business was separated into the Wireless and Communications business and the Microdevices business.

Reduction of raw material plastic consumption

The microwave product manufacturing division of THAI NJR CO., LTD. was faced with a problem: None of the sheet offcuts (waste) resulting from the process of cutting radio-wave absorber sheets could be reused.

To reduce manufacturing costs and make effective use of raw materials, we improved the process of cutting absorber sheets, which had been performed by hand. In the past, 9.0% of raw materials used in manual processes were discarded. By partially automating processes and improving the accuracy of cutting, we succeeded in reducing the waste rate to 0.1%.

Reduction in use of packaging wrapping

Nisshinbo Brake Inc.’s Tatebayashi Plant reviewed the wrapping used to prevent damage to parts during shipping from suppliers.

Wrapping is effective in preventing damage to packages, but wrapping of entire packages results in excessive packaging. To reduce the amount of packaging materials used, we switched to bundling with simple polypropylene (PP) bands. As a result of the success of this solution, about 60% of the shipment volume was changed from wrap wrapping to PP band binding.

In addition, we reviewed the use of wrapping to prevent cargo damage during on-site logistics. As a result, wrapping was eliminated for approximately 5% of products, while 10% were changed to PP band bundling. We plan to continue these activities in 2020 and further reduce the amount of packaging materials used.

Improving recycling rates overseas

Nisshinbo Somboon Automotive Co, Ltd. (NSA) in Thailand, Saeron Automotive Corporation (SAC) in South Korea and Saeron Automotive (Beijing) Co., Ltd. (SABC) in China accelerated the process of thermal recycling*1. In Thailand and China, new thermal recycling plants were established, and in South Korea, a new waste-disposal burden-sharing system*2 was introduced, promoting recycling.

Each company greatly improved its recycling rate. NSA increased by 53% over the previous year to 91% (recycled amount: about 990 tons), SAC increased by 32% over the previous year to 78% (recycled amount: about 1080 tons), and SABC increased by 9% over the previous year to 96% (recycled amount: about 960 tons).
The Nisshinbo Group will continue to work to improve recycling rates overseas.

*1 Thermal recycling: Recovery and utilization of thermal energy generated when waste is incinerated.

*2 Waste-disposal burden-sharing system: Laws and regulations that require separate contributions to be paid when landfill or incineration is carried out.

Measures to reduce waste of scrap materials

Nanbu Philippines Incorporated (NPI) uses scrap materials in the processes of forming molding and plastic sashes for housing construction materials, to reduce plastic use and waste.

From the time plastic molding begins, it takes 30 minutes to 1 hour for the temperature and other conditions to stabilize so that normal products to be manufactured. The plastic that flows through during this period cannot be used to make products. Previously, there was only one input port, and virgin materials were used at start of production. We installed a sub-input port and gradually modified it to enable scrap material* (crushed material) to be input from the sub-input port at the start.

In 2019, we reused a total of approximately 255 tons of crushed materials. Of these, 28% (approx. 72 tons) were used at the start of plastic molding, and the remaining 72% (approx. 183 tons) were used in admixture with virgin material. The ratio of crushed material to raw materials used was raised to 17.7%, and the amount of virgin material purchased was reduced accordingly. The waste recycling rate improved from 94.7% in fiscal 2018 to 96.4% in fiscal 2019.

* Scrap material (crushed material): Collected from gelled fluidized plastic, defective startup products, defective process products, etc., from which foreign materials such as rubber parts are removed and pulverized so that they can be reused as raw materials

Reuse of asbestos waste

Nisshin Environmental Planning Inc. is working to improve the recycling rate of waste. Approximately 460 kg per year of asbestos waste from samples that have been analyzed and discharged is detoxified and reused as recycled materials.

Molten slag*1 and waste asbestos are melted and homogenized at a temperature of 1,500℃ or higher to detoxify the asbestos. Slag incorporating waste asbestos is recycled mainly into products such as caisson filler*2 and cement. Recycling of asbestos waste began in November 2019. Through these efforts, we expect the company's annual recycling rate to increase from 98.0% to 99.4%.

*1 Molten slag: Refuse and its incinerated ash are melted and solidified at high temperatures.

*2 caisson filler: a box-like structure used for port work, etc.

Collection and recycling of unneeded shirts

Since November 2019, Tokyo Shirt Co., Ltd. has been co-sponsoring the brand “BRING™” developed by JEPLAN, INC. We have started collecting unnecessary shirts at 10 stores.

BRING is a collaborative project involving a variety of companies to recycle textile products into usable resources. Today, more than 80 companies take part in the project, and further expansion is planned. Those textile products that cannot be used as clothing are recycled into polyester and automotive interior materials, while those that can still be used are donated or reused. Instead of discarding unwanted clothes as waste, we provide opportunities for reuse and recycling.

In fiscal 2020, the company plans to increase the number of stores collecting unneeded shirts to more than 100 nationwide. By communicating these activities to our customers, we are contributing to the reduction of waste generation, including in the supply chain.

Certification as a 3R-practicing facility under the Tokushima Prefectural Recycling Certification System

In January 2019, Nisshinbo Textile’s Tokushima Plant of was certified as a 3R-practicing facility under the Tokushima Prefectural Recycling Certification System. In collaboration with Nisshinbo Holdings Inc. and Nisshinbo Chemical Inc., both of which are already certified, we are continuing our 3R activities by thoroughly sorting and recycling waste.

Since preparing for certification in 2017, we have maintained a recycling rate of 99% or higher by improving yields and taking on the challenge of recycling materials and defective products. The total amount of waste, including the amount recycled, was also the lowest in the past five years in fiscal 2019, decreasing by 27% from fiscal 2017. In anticipation of the next renewal, we are working to strengthen the efforts of all employees.

Osaka City Environmental Management Bureau Director's Award

Hommachi Iwao Building, owned by NISSHINTOA IWAO INC. in the City of Osaka, was awarded the Osaka City environmental Management Bureau Director's Award in October 2019 for its efforts to reduce waste and recycle resources.

This system is a commendation system for buildings that have been implementing excellent initiatives for many years, targeting large buildings that have made remarkable achievements in promoting waste reduction, appropriate treatment, and maintaining clean living environments.

The Company has been working with maintenance companies and tenants on waste reduction for about the past 10 years. The Bureau gave the Company particularly high marks for sorting and appropriate treatment of 10 categories of waste.
