Environmental Consideration efforts at construction sites
Reducing industrial waste
We have set implementation items based on environmental laws and regulations, and are working to thoroughly formulate and implement management plans to reduce industrial waste generation for each individual property, with the goal of implementing more than 90% of the plans. After construction, we record the implementation details, results, types and amounts of waste generated, and compliance with laws and regulations, and provide feedback to construction plans to manage industrial waste and ensure continuous improvement.
At the Safety and Health Committee, which meets monthly, we confirm the submission of relevant documents, check the disposal status, and provide guidance to ensure the proper disposal of industrial waste. Furthermore, the Industrial Waste Countermeasures Committee confirms and provides guidance on industrial waste management policies and separation rates. We also provide guidance on the proactive adoption of measures that are effective in reducing industrial waste (pre-cutting, 3R, reduction of surplus materials and packaging materials, adoption of economical sizes, reduction of mixed waste, etc.), and strive to reduce the amount of industrial waste generated.
In order to reduce the amount of waste that is ultimately disposed of, we have set a target annual average separation rate for industrial waste at construction sites of 70%, and are working to achieve this. By working to reduce unsorted mixed waste, we are improving our recycling rate.
Action items
- ・Factory production (pre-cut and knock-down method)
- ・Adoption of rental (reused) materials and equipment
- ・Instruction on reducing excess materials brought in and taking surplus materials home
- ・Reduce excess packaging when transporting materials
- - Reduction of waste materials by utilizing economical dimensions
- ・Reducing mixed waste through separate collection
| 2020 | Fiscal Year 2021 | Fiscal Year 2022 | Fiscal Year 2023 | FY2024 | |
|---|---|---|---|---|---|
| Discharged at construction sites Company-wide average industrial waste separation rate (target: 70% or more) |

* Collection period for each fiscal year: February 1st of the current year to January 31st of the following year
Measures against sick house syndrome to prevent health problems
To create spaces that are safe and comfortable to use, we promote safe designs, properly manage the chemical substances used, and work to prevent air, soil, and water pollution.We implement sustainable designs and construction plans (construction review meetings), select certified materials in cooperation with designers, production staff, and other related parties, and manage the use of certified materials by defining essential items for on-site management and registering and recording on-site record photographs.
Environmental Activities in the Office
Reduction of waste generation
In addition to providing a centralized space for the company to share and manage stationery, documents, envelopes, etc., we have stocked stationery mainly with refills, and are promoting the reduction of the use of office paper and the thorough reduction and separation of waste generated from the office. In addition, we are working to reduce waste by requesting a specialized recycling company to take over furniture and fixtures during renovation work at each base, and further promoting the recycling of equipment used on-site, such as workwear, helmets, and safety belts.
Reducing resource use
We aim to reduce our environmental impact by actively promoting the effective use and reuse of resources. We have set up a centralized space for the company to share and manage stationery, documents, envelopes, etc., and we maintain a stock of stationery, mainly refills. As part of our resource utilization management, we monitor the amount of office paper used and strive to reduce paper usage compared to the previous year. We are making progress in digitizing the circulation of forms, reducing paper output by promoting online meetings, and digitizing documents. Paper usage in fiscal 2024 (*) was 2,503,500 sheets (fiscal 2023: 2,732,500 sheets).
*Quantity data for paper used in multifunction printers
Effective use of water resources
In light of the importance of effective use of water resources in our business activities, we are committed to making improvements. Shinagawa Season Terrace, where Tanseisha's head office is located, is situated above the Shibaura Water Reclamation Center, and we not only save water and use gray water, but also make maximum use of the sewage heat and recycled water generated at the center. In addition to utilizing the stable sewage heat as a heat source, the recycled water is used for flushing toilets and irrigating plants.
Resource recycling initiatives
Planning of non-flammable wall material "R Nice"
For the non-combustible wall material (decorative calcium silicate board) "R Nice," which we planned and designed, we worked with the manufacturing company that developed it, as well as with intermediate treatment facilities and recycling facilities to create a process that enables 100% material recycling.

Expanding the area where "RNIHS," a non-combustible wall material that can be recycled 100% through planning and flow construction, is available.
We have developed a fireproof wall material called "R Nice" and created a process for 100% material recycling.
Sustainable materials list
With the aim of raising awareness of sustainable building materials, strengthening our ability to propose them, and increasing their adoption, we are creating a list of materials that will lead to the creation of sustainable spaces and sharing this information with clients.
Efficient use of building material samples
Regarding building material samples necessary for space creation, we have established a company-wide sample room that is operated in cooperation with various manufacturers, and we also utilize a service that allows samples from multiple manufacturers to be packaged and returned together. This not only reduces the number of sample deliveries and packaging materials, but also contributes to promoting the return and reuse of building material samples.
Obtained the forest certification system "FSC®-CoC Certification"
Tanseisha's headquarters has obtained FSC®-CoC certification, the most widely used forest certification system in the world.
FSC® certification is a forest certification system that certifies "proper forest management" as defined by the Forest Stewardship Council®, an international non-profit organization that aims to spread responsible forest management worldwide. There are two types of certification: "FM certification (Forest Management certification)," which examines and certifies forest management based on 10 principles and 70 standards that balance the environment, society, and economy, which were established by agreement with various stakeholders around the world, and "CoC certification (Chain of Custody certification)," which covers the processing and distribution process of forest products. Strict examinations are conducted by independent third-party organizations.
The "CoC certification" that Tanseisha has acquired is awarded to companies that are certified as conforming to standards and rules established by the FSC to prevent the mixing of unqualified wood during processing and distribution. Tanseisha promotes the use of properly managed forest products when proposing and selling the wooden products it handles.

Case Studies
As original, environmentally friendly products, we have produced our first furniture pieces, a "side table" and a "coat hanger," made entirely from FSC®-certified wood. These two products were designed and delivered to fit the concept of the "Carbon Offset Room" in the co-working space "point 0 marunouchi," which aims to realize the "office space of the future."

Supporting forest management activities
Donations to the "Green Fund"
Tanseisha supports the main purpose of the "Green Fund" promoted by the National Land Afforestation Promotion Organization (NLAPO) and donates to it.
The "Green Fund" will be used for various "reforestation and human resource development" activities, which will lead to the creation of forests in local communities and in Japan and overseas.
