Relationship with the Environment

Report on Environmental conservation
(Information on sites in Japan)

The Company develops, manufactures, and sells chemicals for manufacturing electronic substrates. Recognizing that our business activities consume energy and resources, we will work to reduce the environmental burden.
In addition to complying with environmental laws and regulations 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.

Relationship between business activities and the environment

We make efforts to grasp the amount of energy and resources consumed in our business activities, the amount of CO2 emitted, the amount of wastewater discharged, and the amount of industrial waste discharged. KPI will be set based on the material issues described in our Company’s 2030 Vision (Phase 1).

Electricity consumption

Three factories were in operation, namely Amagasaki, Nagaoka, and Nishinomiya, but the Nishinomiya Factory stopped operating at the end of 2021. In fiscal 2022, we began operating two factories. We believe that the increase in electricity consumption is necessary to increase the manufacturing volume, operate three factories, and improve the working environment. However, in order to reduce the environmental burden as much as possible, we generate electricity from sunlight on the roof of the Amagasaki Headquarters.

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 96%.

Water usage and amount of wastewater

Because water is a key ingredient in our Company products, we cannot reduce the amount of water used as the ingredient. 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, and wastewater treated in line with the regulated standards is discharged into the sewerage system. We strictly control the drainage so that it does not spill out while exceeding the standard value. In fiscal 2021, there were no wastewater discharges that exceeded the standard values.

Efforts for reuse of plastic containers

On April 1, 2022, the Law Concerning the Promotion of Recycling of Plastic Resources (the Law for the Promotion of Recycling of Plastic Resources) was promulgated. The Company uses plastic containers such as plastic cans, plastic drums, and IBC to put its chemicals in. As a company that uses and discharges plastic products, we are working to reduce plastic emissions through our supply chain. After the chemical solution is used by the customer, the container is no longer needed and is subject to disposal. We collect and reuse plastic containers in order to make effective use of limited resources without waste. Containers collected from customers are sorted to determine whether they can be reused. Containers that can be reused are cleaned and reused by our Company and contractors.
Although our domestic customers are cooperating with this initiative, a high percentage of plastic drums are shipped overseas, and the recovery and reuse rates for those tend to be lower than those of other containers. In fiscal 2021, 79.0% of plastic drums were shipped, 21.7% were collected, and 68.1% were reused.
The recovery rate of plastic cans was 42.3%, and the reuse rate was 78.1%.
For IBC, while the number of customers delivered to is limited, the domestic shipping rate is high, and the recovery and reuse rates tend to be higher than those of other containers.
In fiscal 2021, the domestic shipping rate was 63.4%, the recovery rate was 60.5%, and the reuse rate was 98.5%.

Proper disposal of wastes

The amount of industrial waste discharged in fiscal 2021 was 336 tons, a decrease of 29.2 tons (8.0%) from fiscal 2020. Of this amount, specially controlled industrial waste amounted to 152 tons, an increase of 34.4 tons (up 29.3%) from fiscal 2020. The final amount of disposed industrial waste was 55.7 tons (recycling rate : 83.5%). We started collecting data on the final disposal amount from FY2018, and FY2020 was almost the same as FY2018 and FY2019. We also sort metals and sell them as valuables, and no metal is discarded as waste metal. Going forward, we will strive to curb the generation of waste, and make efforts to reduce our environmental burden by thoroughly separating and recycling the generated waste.

Environmental Accounting for FY2021
(Information on sites in Japan)

We use environmental accounting to calculate cost (expense) and effect (quantity) as a mechanism to quantitatively evaluate our environmental conservation efforts.

Table Environmental conservation cost in FY2021

Environmental conservation costs in fiscal 2021 totaled 1,866,892 thousand yen. 57% of this amount was used for pollution prevention costs. This is due to the large depreciation cost of wastewater treatment equipment at the Higashi-hatsushima R&D Center, which was restarted in April 2020. Upstream and downstream costs associated with the collection of used containers and outsourcing of container cleaning were less than 1%, but increased approximately 0.7 million yen from fiscal 2020.

Table Environmental conservation effects in FY2021

The environmental conservation effect is expressed based on the change in the absolute amount from the previous year (FY2020 conversion). Primary units (the amount per ton of production) are also used for some indexes. We are continuing to be actively involved in environmental conservation activities based on the recognition that one of our important missions is to reduce environmental loads.
