Work toward saving resources
In fiscal 2022, the NOF Group generated 152,678 tons of waste, of which 82.9% was reduced through internal weight reduction measures and 16.5% was outsourced for external processing. As for the breakdown of the waste externally processed via outsourcing, 10.8% was recycled externally, 4.9% was reduced externally, and 0.7% was disposed via landfills, for a recycling rate of 11.4% of the total waste generated (including internally). 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.

Recycling of resources
Promotion of drive toward Zero Emissions*
The volume of waste discarded by the Domestic Group for final disposal by landfill was 55.1 tons in fiscal 2022, with the Zero Emissions rate standing at 0.035%.
Meanwhile, NOF’s final landfill volume was 36.9 tons, with the Zero Emissions rate standing at 0.024%.
NOF will continue to promote the separate collection and recycling of waste, and will strive to reduce the volume of final landfill disposal.
＊Here, this means an endeavor to make the disposal quantity of industrial waste through corporate and production activities close to zero.
NOF’s definition of zero emission: Volume of final disposal by landfill/volume of waste, etc. generated × 100 ≦ 0.10

Recycling of valuables from waste
In FY2022, the amount of waste plastic recycled by the NOF Group increased to 791 tons, and the recycling ratio against the amount discharged also improved to 91%. In addition, the Domestic Group’s sales from the recycling of waste amounted to 403 million yen. We will continue to actively sort, recycle, and reuse waste plastics and also continue our recycling efforts.

Recycling of resources
The NOF Group is conducting the following efforts as resource circulation initiatives.
（1）Promotion of sales of valuable waste and internal processing
（2）Reduction of waste generated by maintaining separate disposal and
improving processes
（3）Ongoing search for recycling and disposal contractors as well as
processing implementation
（4）Landfill reduction through recycling of existing waste
In this way, we promote resource circulation, reduce waste, and lessen our environmental impact
