Sustainability / Environmental ReportReduction and Recycling of Industrial Waste
The Daicel Group follows its Basic Policies for Responsible Care to implement a variety of initiatives for reducing environmental impacts, including the preservation of water resources, environmental management of air pollution, reductions in emissions and the appropriate management of chemical substances at all of its business sites. With regard to waste reduction and recycling efforts in accordance with the Japan Business Federation’s “Voluntary Action Plan for Establishing a Sound Material-Cycle Society,” we are further promoting the 3Rs (reduce, reuse, and recycle) to reduce the amount of waste. This includes efforts to save resources, reuse, and recycle as we strive to realize a circular society.
Toward Achieving Our Medium-term Targets
In our medium-term target for the period ending FY2026/3, which was announced in 2020, we are focusing on raising the recycling rate at Daicel's business sites and domestic Group companies to 99% or higher and achieving zero emissions at Daicel’s business sites and domestic Group companies. To improve our recycling rate, we will continue to apply the 3Rs to industrial waste by promoting the effective use of resources and reducing the amount of waste incinerated without energy recovery. In regard to achieving zero emissions, we will work on enhancing our recycling rate for plastic waste and organic sludge.

Initiatives to Reduce Industrial Waste
The Daicel Group manufactures a variety of chemical products, and waste is generated in the manufacturing processes. Examples include waste in the form of cinders and particulates from the burning of solid fuels for energy production, waste liquids, cleaning fluids, remnants, defective products, and decommissioned equipment. The Daicel Group strives to achieve zero emissions (with less than 1% of landfill disposal of industrial waste generated) by taking a proactive approach to recycling cinders and particulates that account for about half the waste produced in Japan.
In FY2023/3, the amount of industrial waste generated by Daicel’s business sites and the domestic Group companies decreased by 2% compared to the previous fiscal year to 142 thousand tonnes, and the production of some products was adjusted. The recycling rate was unchanged year-on-year at 98%. The amount of landfill waste fell 11% from the previous fiscal year to 1.1 thousand tonnes.
In FY2023/3, the landfill rate for Daicel’s business sites and domestic Group companies was 0.9%, so that once again we achieved our target of zero emissions following on from the previous fiscal year.
As a company involved in businesses that create industrial waste, we ensure that all our waste is properly disposed of by checking permits, disposal methods, and other details of the contracted industrial disposal companies at their sites. In the coming year, we will continue to work on waste recycling and reduction.

Promoting the 3Rs
The Daicel Group pursues the 3R initiatives of reduce, reuse, and recycle, including the conservation of resources, under the Daicel Group’s Basic Policies for Responsible Care.
Major 3R Initiatives
Scroll left or right
|Reduce||Improve the manufacturing facility for inflators||We seek to reduce industrial waste by modifying the manufacturing facility to lower defect rates for welding and caulking.|
|Engineering plastic||We seek to reduce industrial waste by introducing a drying process to reduce the volume of deposits with a strong odor, which occurs during wastewater treatment.|
|Reuse||Reuse palettes for shipping||We promote reuse by switching to palettes that are easier to reuse and by conducting bulk collection of palettes.|
|Reuse containers||We promote reuse by cleansing containers to avoid single use.|
|Recycle||Recycle boiler slag into raw material for cement and other materials||We select multiple disposal companies to promptly implement recycling.|
|Recycle metals||We recycle metals by sorting waste generated by plant closures.|
|Recycle inflators||We implement the treatment of explosive waste from inflators of scrapped automobiles at our facilities, and we sort metals and plastics for recycling.|
Initiatives Addressing Marine Plastic Waste
As part of Preserving Biodiversity activities, the Daicel Group strives to solve the marine plastic waste problem.
