Resource Recycling / Waste

Policy

Policy (our fundamental view)

The NOF Group prioritizes conducting the following efforts as resource circulation initiatives.
 

  1. Promotion of the sale of valuable waste and internal processing: We sell waste as valuable resources and actively promote internal processing. This promotes the efficient use of resources through the reuse and recycling of waste.
  2. Reduction of waste generated by maintaining separate disposal and improving processes: By maintaining separate waste disposal and improving processes, we are reducing the amount of waste generated. This initiative prevents resources from going to waste and ensures their efficient use.
  3. Ongoing search for recycling processing contractors as well as processing implementation: We work continuously with recycling and disposal contractors and actively implement waste recycling processing. This initiative promotes the reuse of resources, efficient use of resources, and reduction of waste.
  4. Landfill reduction through recycling of existing waste: By recycling existing waste, we are reducing disposal into landfills. Through this initiative, we are effectively utilizing resources and contributing to the reduction of waste and environmental impact.
     

The circular economy is an economic model that aims to create sustainable value through the efficient use of resources and the minimization of waste. It promotes reuse and recycling, reduces environmental impact, and contributes to the long-term enhancement of corporate value.

Resource Recycling Targets

The NOF Group promotes resource recycling efforts by setting targets.
 

  1. Zero emissions*1 rate: 0.10% or lower annually We promote waste separation and recycling, and reduce the generation of waste disposed of in landfills as much as possible.
  2. Waste plastic recycling*2 rate: 94% or more annually (from FY2024) We are advancing the recycling of waste plastics for recycling and effective use of resources.
     
The utilization of resources is shown in a circle with arrows. It shows how resources go from raw material procurement, materials, manufacturing, filling and packaging, to utilization, and then disposal or packaging reuse/recycling, material recycling, chemical recycling, and thermal recycling into fuel.
  1. Here, this means an endeavor to make the disposal quantity of industrial waste through corporate and production activities close to zero.
    Definition of zero emissions rate:(Volume of final disposal by landfill / volume of waste, etc. generated) × 100
  2. Definition of recycling rate:
    (Volume of waste plastics recovered through thermal, material, or chemical processing / Waste plastics generated) × 100

Initiatives Toward Saving Resources

In fiscal 2024, the NOF Group generated 148,643 tons of waste, of which 83.1% was reduced through internal weight reduction measures and 16.3% was outsourced for external processing. As for the breakdown of the waste externally processed via outsourcing, 10.5% was recycled externally, 5.2% was reduced externally, and 0.7% was disposed via landfills, for a recycling rate of 11.0% of the total waste generated.
As part of our resource circulation efforts, we are improving processes to increase yield and reduce the amount of waste generated, promoting the sale of valuable waste and internal processing, recycling existing waste for landfill reduction, maintaining separate disposal and reducing waste generated, and continuously searching for plastic waste recycling and disposal contractors and advancing processing by them. We will continue to actively work to promote resource circulation, reduce waste, and lessen our environmental impact.

This chart shows the amount of waste generated by the NOF Group. The amount of waste generated internally was 148,643 tons, of which 7,395 tons were hazardous substances. 840 tons were recycled internally as useful waste, and all of this was reused. Of the amount recycled internally, 839 tons were hazardous substances. The amount of useless waste lost internally was 123,505 tons, of which 25 tons were hazardous substances, 120,792 tons were dehydrated (dehydrated water treated internally), and 2,714 tons were incinerated, of which 25 tons were hazardous substances. Zero tons were sent to internal landfills. Of the waste, 24,298 tons were outsourced for external treatment, of which 6,531 tons were hazardous substances. The amount recycled externally as useful waste was 15,555 tons, of which 14,879 tons were recycled and 676 tons were used for thermal purposes. Of the amount recycled externally, 2,839 tons were hazardous substances. The amount of useless waste sent to external waste reduction sites (incinerated, neutralized, etc.) was 7,684 tons. The amount sent to external landfill sites was 1,058 tons, of which 23 tons were hazardous materials.

Promotion of Drive Toward Zero Emissions

In fiscal 2024, the final landfill disposal volume for the Domestic Group was 72.2 tons, for a zero emissions rate of 0.047%.
Meanwhile, NOF’s final landfill volume was 65.3 tons, with the zero emissions rate standing at 0.043%.
We will continue to promote separate collection of waste and recycling to reduce the final disposal volume by landfill.

This is a bar graph showing trends in final landfill disposal volume. Units are tons per year. For NOF: 40.3 in fiscal year 2020, 53.6 in fiscal year 2021, 36.9 in fiscal year 2022, 48.1 in fiscal year 2023, and 65.3 in fiscal year 2024. For the domestic group: 681.3 in fiscal year 2020, 135.0 in fiscal year 2021, 55.1 in fiscal year 2022, 69.0 in fiscal year 2023, and 72.2 in fiscal year 2024. For the NOF Group: 1,588.4 in fiscal year 2020, 949.7 in fiscal year 2021, 1,086.2 in fiscal year 2022, 616.6 in fiscal year 2023, and 1,058.4 in fiscal year 2024.
