Conservation of Resources, and Recycling

Initiatives Related to Waste and Valuables

For sustainable resource recycling activities, we promote efforts in recycling activities and reduction of generated amounts of waste and valuables.

Concepts Related to Effective Use of Resource

Pioneer aims not to input useless materials and to use input resources without waste to deliver products. Under this concept, Pioneer carries out activities by incorporating waste (unwanted objects) and valuables (object having market value as a resource) generated at the time of business activities into evaluation indices.

Classification of waste in workplace Promotion of recycling activities (reduction in landfill wastes) Enhancement of recycling quality (thermal collection to Recycle) Reduction in generated amounts including valuables (do not use useless resources)

Reduction of Waste and Valuables

In order to reduce the generation of waste and valuables, constant improvements are made to avoid the use of materials not required in production processes, including recyclable valuable resources.
Moreover, Pioneer implements activities to recycle waste from offices and plants to reduce landfill disposal down close to zero. In the year ending March 2018, we recycled 99.7% of our waste in Japan and 99.0% overseas.

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

Previously, the Kawagoe Plant disposed of spent isopropyl alcohol (IPA), which had been used for cleaning manufacturing machinery, after use. The plant looked to see if a recycled product could be purchased from a discharge source, so that waste liquid would be able to be taken away at the time of delivery, thereby offering benefit in terms of transportation. After six months of trial and error, the plant succeeded in obtaining delivery of a recycled product, which would offer the same performance as a new product, from a discharge source.

Recycle Promotion Activities (Kawagoe Plant)

Although trial products for which performance evaluations have been completed are disassembled for disposal for security reasons, classified recovery is performed while exchanging information with recycling companies in order to recover useful metals. At the recovery locations, recovery unit prices are indicated according to the type of IC, circuit, material, etc. Classification is performed with a greater level of intention now that disposed objects are indicated as being marketable goods of value.

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

Numbers are assigned to respective floors and the numbers are indicated in all garbage bags to enable feedback to the division concerned when there is a classification error. In regard to items with which an error occurred, the 10 worst classification errors are notified in the plant in the environmental education by e-learning.

Production plastics recovery system construct enables recycling of 24 types (Kawagoe Plant)

Kawagoe Plant have been working on sort and recycle plastics waste such as vinyl wrap and mirror mat. In addition to these activities, we thoroughly sorting them by making shelves for each item and labeling divsed in cooperation with the Production Department. As a result we became able to expanded to recycle from 8 items to 24.
This has enabled the recycling of almost all production plastics and reduced the amount of disposal.

Battery Recycling at Distributions

In order to comply with battery recycling directives of various parts of the world, Pioneer practices marking and removal-facilitating design and promotes battery collection at vendors. PBL (production corporation in Brazil)*1, collection boxes were uniquely created for collecting used (recyclable) batteries, installed at the service agent's reception counters (approximately 200) variously located in Brazil. The collected batteries are processed in accordance to the applicable battery regulation in the country.
Also in Japan, compact rechargeable batteries are used in our products such as cordless phones, portable navigation units, etc. Therefore, based on the Law for Promotion of Effective Utilization of Resources, we have joined the general incorporated association, JBRC*2, as a recycling cooperation enterprise and are engaged in the collection and recycling of used compact rechargeable batteries.

Discharged Water Recycling Facility
in Semiconductor Plant

Although Pioneer Micro Technology (Yamanashi Prefecture) was using groundwater for production of semiconductor devices, it has begun to use discharged water from the production process for conservation of water resources. Piping connections were upgraded so that the optimum discharged water flows to the recycling facilities. Thus, half of the water which previously flowed to sewage from the discharge water processing facility was returned to the reuse system from the recycling facility.
