Relationship between business activities and the environment

The Company develops, manufactures, and sells chemicals for manufacturing of electronic substrates. In conducting business activities, we consume energy and use resources. Recognizing this, we are working to reduce our environmental burden.
In addition to complying with environmental laws and regulations, etc., related to business activities, we provide products that take into consideration energy conservation measures, waste reduction, proper management of chemical substances, and product life cycle. The aim is to make effective use of resources, prevent pollution, and conserve the environment.

Electricity consumption

The Nishinomiya Factory ceased operation at the end of 2021, after which, two factories have been operating, namely the Amagasaki Factory and the Nagaoka Factory. Electricity consumption in FY2023 was almost the same as in FY2022, but the intensity increased significantly because production volume fell. Electricity use is expected to continue to increase as it is mainly used to improve the working environment. In order to reduce our environmental impact as much as possible, we are generating solar power on the roof of the Amagasaki Headquarters. In addition, we began purchasing renewable energy at the Amagasaki Headquarters in FY2023. We have continued to purchase renewable energy in FY2024.

CO₂ emission

We have calculated the GHG protocol Scope 1 (fuel) and Scope 2 (electricity and heat) as CO² emissions. Scope 2 (electrical) accounts for 97%. We calculated Scope 3 emissions for some categories.

Water usage and amount of wastewater

Because water is a key ingredient in MEC’s products, the amount of water used changes according to changes in the volume of products manufactured. We understand the amount of water used and are aware that we use a large amount not only in our raw materials but also in our manufacturing facilities, container cleaning, and substrate processing lines in our R&D activities. For this reason, we are working to reduce the number of times equipment is cleaned, to introduce automatic container-cleaning equipment, and to reduce wasteful use in substrate processing line work.Water used in manufacturing and R&D operations is treated in wastewater treatment facilities in line with the regulated standards and discharged into the sewerage system as wastewater. We manage wastewater to ensure that we do not discharge wastewater that exceeds standards. In FY2023, there was one incident of wastewater discharge that exceeded standards, and we reported it to the government. After the discovery of the exceedance of standards, we also took appropriate measures, and as a result of the investigation of the cause and countermeasures, there have been no subsequent occurrences of such incidents.

  

Reuse of plastic containers

In order to make effective use of limited resources without waste, we collect polyethylene containers that our customers no longer need after chemical use. We sort containers collected from customers to determine if they can be reused, and those that can be reused are cleaned and reused by the Company and contractors.

Proper disposal of wastes

The amount of industrial waste generated in FY2023 was 423 tons, a decrease of 122 tons from FY2022 (down 22%). The decrease in 2022 is due to the various discharges of industrial waste as part of measures associated with the closure of the Nishinomiya Factory. The amount of specially controlled industrial waste was 181 tons, a decrease of 77 tons from FY2022 (down 34%). The final amount of disposed industrial waste was 64.3 tons. In FY2023, 6.2 tons of industrial waste was discharged as the last discharge before the transfer of the Nishinomiya Factory at the end of May 2023. We will continue our efforts to limit the amount of industrial waste generated, and endeavor to reduce the final disposal volume by thoroughly sorting industrial waste generated.
