Basic Policy

Sumitomo Forestry is working to advance toward building a sustainable circular society. Particularly at construction and building sites, where the environmental impact of industrial waste is relatively high, we endeavor to mitigate this environmental impact through initiatives to restrict the production of industrial waste, reuse and process materials for recycling.

Initiatives to Reduce Industrial Waste

Initiative for Reduction of Industrial Waste Generated at New Housing Construction Sites

FY2019 Initiatives to Reduce Industrial Waste

In July 2014, Sumitomo Forestry set up the Waste Reduction Working Group comprising representatives from the product development, material procurement, production management and environment divisions. The working group has been planning and implementing a wide range of measures to reduce waste on new housing construction sites.

We discovered two-thirds of all our waste is made up of wood waste, gypsum board and cardboard from detailed data about the waste that is produced aggregated from the industrial waste management system used under this inter-region certification, which has been in operation since 2012. We are working to reduce waste by concentrating on these three primary forms of waste.

In fiscal 2019, we strove to standardize sub-floor gypsum board that uses new curing methods and revised standard sizes adopted in fiscal 2018.

In particular, the new curing methods can realize approximately 150 kg reduction of waste (cardboard) per home by replacing conventional disposable curing materials with reusable curing materials.

The usage rate in properties completed by the end of fiscal 2019 increased to 83% for reusable curing materials and 91% for sub-floor gypsum board, which is gradually showing effective reductions of industrial waste.

We are also furthering pre-cut initiatives related to roof slate, siding, and Kizure panel materials that have been measured and processed on sites. Practical introduction in stages of these measures begins in fiscal 2020. We expect these pre-cut materials to drastically reduce emissions since pre-cutting is effective in reduction of industrial waste with heavy weight.

Furthermore, we strive to raise awareness on construction sites and conduct educational activities by providing feedback of data about waste emissions from each property to the sites.

Reduction Rate of Industrial Waste Generated at New Housing Construction Sites

The Sumitomo Forestry Group has also set an 18% reduction in the volume of industrial waste generated per household at new construction sites by fiscal 2021 compared to fiscal 2017 levels in the Mid-Term Sustainability Targets. In fiscal 2019, this initiative achieved gradual results, reducing the amount of industrial waste per new house by 10% from the fiscal 2017 level, and we are well on our way to achieve our fiscal 2021 target.

Reduction Rate of Industrial Waste Generated at New Housing Construction Sites (Per Household)

Total Emissions (kg) Reduction Rate
FY2017 (Baseline) 3,325 -
FY2018 result 3,274 -2%
FY2019 result 3,002 -10%
FY2020 target 2,950 -11%
FY2021 target 2,730 -18%

Initiative for Recycling of Industrial Waste Generated at New Housing Construction Sites

Sumitomo Forestry meticulously sorts waste produced on new housing construction sites. We will raise awareness through mediums such as posters including specific waste information to make sorting of the 11 categories of waste easier. We have also engaged in efforts to reuse rather than dispose of wood base and packing materials used when transporting precut structural and other materials.

The Sumitomo Forestry Group set a goal of achieving 98.0% waste recycling rate for new construction sites by fiscal 2021 as part of the Mid-Term Sustainability Targets. Recycling rate was 94.3% in fiscal 2019 since recycling on some intermediate processing sites in some regions did not work well, but we will work to consider the adoption of new processing sites that can execute the recycling to improve our recycling rate.

Acquisition of the Inter-Region Recovery and Recycling Certification by the Ministry of Environment

Sumitomo Forestry acquired the inter-region recovery and recycling certification from the Ministry of the Environment in December 2010. This certification enabled us to build our own industrial waste recycling system by allowing transport of waste by proprietors other than waste disposal operators.

Our industrial waste management system for new housing construction sites helps contribute to the rationalization of waste disposal by using returning transportation for collecting waste while also securing traceability by applying bar codes to waste and collecting accurate data about the volume of waste generated.

Operations at the Metropolitan Area Recycling Center

Sumitomo Forestry used the acquisition of the inter-region recovery and recycling certification to establish the Metropolitan Area Recycling Center in Kazo, Saitama Prefecture for advanced sorting and data collection.

The Metropolitan Area Recycling Center started full operation in fiscal 2012 and has been collecting and processing waste produced by new housing construction sites of the metropolitan and six prefectures of Kanto (Metropolitan Tokyo, Kanagawa, Chiba, Saitama, Ibaraki, Tochigi, and Gunma prefectures).

Setting up the Metropolitan Area Recycling Center brings data feedback to product development, material procurement and production management divisions by facilitating the collection of specifications, construction branches as well as the detailed status and trends of waste generation in each region. This data is being leveraged in our initiatives to reduce waste.

This initiative works to expand operation under the certification for the inter-region recovery and recycling, build processing routes led by Sumitomo Forestry, and further promote recycling even in regions outside the metropolitan area.

Waste Management for Demolition Work

We are strengthening management by building a system able to confirm the type, quantity and packaging of waste to transport from demolition work sites using mobile phones and smartphones which is adopted by all of our demolition partners.

The delivery confirmation invoice sent thanks to input into an electronic manifest checks whether the issuance is correct via our system.

Together with Construction Contractors

Sumitomo Forestry publishes monthly safety, environment and quality inspection information that includes information and topics about safety and the environment to help avoid industrial waste-related risks by repeatedly raising awareness at branches and construction contractors.

Joint Environmental Training with Business Partners

In fiscal 2017, we began conducting joint training for personnel in charge of industrial waste management and administration personnel at branches and the person in charge at demolition contractors.

This joint training aims to raise legal understanding, such as laws related to waste treatment and cleaning (Waste Disposal & Public Cleaning Law) and laws related to the recycling of materials in construction work (Law Concerning Recycling of Materials from Construction Work), share information about industrial waste management risks, and create consistent management methods, such as input procedures of digital manifests to eliminate industrial waste risks.

The joint training also helps facilitate smooth communication between personnel in charge of administration at Sumitomo Forestry and demolition contractors as well as improves the management of digital manifests that are vital to industrial waste management.
