Resources saving and Recycling

We reduce use of valuable resources,
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.

  1. Garbage separation at workplace
  2. Promotion of recycle activities
    (Removal of landfill waste)
  3. Improvement of recycle quality
    (Thermal Recycle → Reuse)
  4. Reduction of generation amount including valuables
    (Do not use unnecessary resources)

In order to reduce the Wastes and Valuables, we make efforts continuously not to input unnecessary materials into production process including valuables which can be recycled. Moreover, we recycle the waste from our plants, and take activities to attempt to eliminate the landfill waste. On the March 2020, the recycle rate in Japan was 99.8%.

Example of Activity for Efficient Use of Resources
(Kawagoe Plant)

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.

Recycle Promotion Activities by Separation Dismantling
(Kawagoe Plant)

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.

Example of increase in classification awareness
by numbering garbage bags (Kawagoe Plant)

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.


  1. Manufacturing
  2. Customer use
  3. Disposal
  4. Treatment
  5. Manufacturing

Consider collection,
and dismantling.

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.

  1. Less weight, less volume
  2. Recycling of resources, use of recycled parts
  3. Increase in resource recyclability
  4. Ease in manual dismantling and classification
  5. Packaging
  6. Environmental preservation
