  • 1. We will comply with legal regulations and matters agreed on by the Company for the environment regarding business activities, products and services.
  • 2. We will endeavor to reduce environmental burdens, reduce environmental pollution risks, and protect biological diversity and ecological systems by saving energy and resources, promoting recycling, reducing waste, reducing the consumption of chemical substances and engaging in green procurement.
  • 3. We will continue to improve our activities by utilizing the environmental management system, setting environmental targets to achieve the Environmental Policy, conducting evaluations on environmental performance, and reviewing them regularly.
  • 4. We will thoroughly inform all employees of the Environmental Policy and endeavor to conduct necessary education and enlightenment activities to engage in environment conservation activities.

Provision of Optimal Products and Merchandise for Environmental Measures

KONDOTEC also offers recycled PP strapping merchandise made from plastic collected from consumers (left photo), and construction deck plates made from biomass plastics (right photo), both of which an Eco Mark certified.


A new concrete release agent based on petroleum stock. As over 95% of its raw materials have a biodegradability of approximately 75% in the OECD 310F test of biodegradability, it is considered to degrade rapidly in the natural environment.

Oil hunter

This is an eco-mark certified oil absorption mat using recycled materials. It is used for the disposing of oil at the time of marine pollution caused by oil spills and at factories which use oil.

Mash up cover
Oil gator

Joints in building materials intentionally create rust to fix building materials to each other through friction bonding. For this reason, masking tape or other means was used on surfaces as covering to prevent paint from coating the joints. Our development of the mash-up cover makes this covering possible without generating tape waste.

Business Activities Paying Attention to the Environment

Response to climate change and information disclosure in line with TCFD recommendations

At KONDOTEC, in considering a path for sustainable growth, we do take into account the significant impact issues associated with climate change will have on future business activities. We are currently taking steps to recognize the impact our business activities have on the environment by management of emissions, and other measures.
We view the shift to a low-carbon society as a key opportunity for us, and looking ahead we will look to pursue information disclosure in line with TCFD recommendations, while implementing measures addressing climate change.

Risk management system

In collaboration with all divisions Company-wide, SDGs Promotion Department compile, assess, and identify risks and opportunities facing the Company in relation to climate change. Climate-related risks and opportunities that have been assessed and identified are reported to the Board of Directors for further supervision.

Main risks and opportunities associated with climate change

Climate-related risks and opportunities currently identified through extensive discussion with each Company division are outlined in the table below. The corresponding SDG targets are sized according to their degree of relevance.
Looking ahead, we will delve deeper into ways we can continue to better serve society, including strengthening current value creation processes, and in the specific ways we tackle issues that come to light, and tie this back to information disclosure based on TCFD recommendations.

Initiatives for Environmental protection and Energy-saving
Installation Solar power generation

Our two factories, Sanwa Denzai Co., Ltd. and TOKAI STEP CO., LTD. operate the solar power generation system in our power sales business.
In Electrical Equipment and Structural Steel Materials segments, we handle materials related to solar power generation systems and frames respectively, and focus on sales through synergies within the Group.

Quick delivery by four-factory structure and inventories at each operating site

We have established factories at four locations in Japan (Hokkaido, Ibaraki, Shiga and Fukuoka), with made-to-order products such as braces and anchor bolts produced at and shipped from the nearest factory to the customer. Using the four-factory structure, we reduce environmental burdens and transportation costs as well as deliver products quickly. For products and merchandise which can be stored as inventories, in addition to inventories at logistics centers, we keep a certain amount at warehouses established at individual operating sites so that we can respond to abrupt demand while realizing environmental burdens and cost reduction ,and quick delivery.

Acquisition of ISO14001

We obtained ISO14001, international standards for environmental management, at all four factories, engaging in environment-friendly operations for factories.

Environmental conservation activities

As part of efforts to reduce CO₂ emissions, KONDOTEC has begun plans to replace Company cars with EVs, and to switch to renewable energy sources to power Company facilities. Such moves to EVs and renewable energy power sources have already gotten underway at our Head Office in 2021.
