and promote recycling of the resources.
Pioneer aims not to input unnecessary materials but to utilize the input materials without ruined then ship products. With this concoct, Pioneer includes wastes (unnecessary materials) and valuables (materials having market values as resources) generated during business activities into assessment index to proceed the activities.
We carry out activities to minimize landfill waste by reducing the production of and recycling waste and valuables. Our recycling rate for the fiscal year ended March 31, 2021 was 99.9% (in Japan).

At the Recycle Center in Kawagoe Plant, we collaborate with business partner to recycle the stretch film for package which is discharged in this plant into plastic bags, then reuse as trash bags in this plant. By recycling 285 kg of the waste film material in June 2021, resources were saved, and 839 kg of the CO2 emission could be reduced.
These recycled plastic bags are planned to be used not only Kawagoe Plant but also other plants.
Stretch film for package of parts and products is recycled to plastic bags
In the company cafeteria in Kawagoe Plant, we have been devised to reduce the food loss. Generated food wastes despite the effort had been used for thermal recycle by incineration, but we newly contracted with a company which generates renewable energy from food waste, then led to biogas power generation by methane fermentation of the food waste from cafeteria. Incineration residue is not generated, so it can be contributed to the reduction of final disposal volume.

Food wastes from cafeteria
We changed handling method of the "IPA (isopropyl alcohol)" used for cleaning of the production machines from disposing to recycling after use. Moreover, we can carry out the waste solution when carrying in the recycled solution, resulting energy can be saved for transportation and CO2 can be reduced.
Recycling Isopropyl Alcohol (IPA)
The trial products which performance evaluations had been conducted during development were dismantled and disposed. At that time, we exchanged information with recycling companies to specify the dismantle level which can be recycled easily. At the collecting location, the valuables prices for each type of IC, circuit, material, etc, are posted, so that it improves awareness of employees for recycling.
Numbers are assigned to respective workplaces and the numbers are indicated in all garbage bags to enable identification and feedback to the division concerned when there is a classification mistake. In regard to items which mistake occurred, the worst 10 classification mistakes are notified in the plant with the environmental education by e-learning.
At the parts procurement stage, we select materials that enable reducing the number of types of plastic materials used, not adhering to different types of plastic materials, not attaching resin film to packaging boxes, and promoting use of recycled materials. We select materials which are easily collected, classified, and dismantled.
At the design stage, we conduct the product assessments for the following items, and specify the target values for each item. We promote product development with focused on resource recycling.
