The Basic Concept of Zero Emissions

The Sumitomo Forestry Group defines achievement of zero emissions as a recycling rate of 98% or more using no simple incineration or landfill for all industrial waste produced by each business site*. Based on this definition, domestic manufacturing facilities achieved zero emissions in fiscal 2009 while new housing construction sites achieved zero emissions in metropolitan areas in fiscal 2012. Our overseas manufacturing plants achieved zero emissions in fiscal 2020.

The new Mid-term Sustainability Targets from fiscal 2019 to fiscal 2021 set a target of 15% reduction in the amount of final disposal throughout the entire Sumitomo Forestry Group compared to fiscal 2017 to achieve zero emissions and further reduce the environmental impact of our business activities. Furthermore, within the Mid-Term Sustainability Targets, we take factors such as the state of progress of business activities and the resulting waste generation into account, establishing the following seven categories for a more finely differentiated effort to achieve zero emissions than in the Mid-Term CSR Management Plan. These categories are: New Housing Construction Sites, Domestic Production Plants, Power Generation Business, Renovation Business, Lifestyle Service Business, Overseas Manufacturing Plants, and Demolition Work sites.

* Includes new housing construction sites, domestic manufacturing plants, power generation plants, lifestyle service businesses, overseas manufacturing plants and demolition work sites

Manufacturing Business Initiatives

Initiatives at Domestic Manufacturing Facilities

Sumitomo Forestry Group managed to achieve a recycling rate of 99.1% against the target of 99.3% while zero emissions (recycling rate of 98% or more) were achieved at Sumitomo Forestry Crest and the Agro-Products division of Sumitomo Forestry Landscaping in fiscal 2020* as a result of ongoing efforts to reduce waste emissions, for example by tightening the sorting of industrial waste at each manufacturing plant, effective use as resources (thermal use) without simple incineration, and selling it for a profit.

* Data collection period: January to December 2020

Initiatives at Overseas Manufacturing Plants

We are working toward zero emissions with two new Group companies from fiscal 2019: Sinar Rimba Pasifik (SRP) in Indonesia and Canyon Creek Cabinet (CCC) in the United States in addition to five main manufacturing companies outside Japan*. For example, Kutai Timber Indonesia is advancing zero emissions activities from the collection of wood waste generated during the particle board manufacturing process to reuse as boiler fuel or in wood building materials as well as the use of offcuts produced in manufacturing products as novelty goods.

The recycling rate in fiscal 2020 achieved zero emissions at 98.4% against our target of 98.2%.

Initiative for Reduction of Industrial Waste Generated at New Housing Construction 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 2020, the reduction rate for the amount of industrial waste per new household had stagnated at 10% compared to fiscal 2017. However, we have steadily furthered the precuts of Kizure Panels and roof slate that began in fiscal 2020 and plan to see reductions in the amount of industrial waste emissions in fiscal 2021 as Sumitomo Forestry gradually approaches completion of buildings using the precut structural materials.

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* result 2,977 -10%
FY2021 target 2,730 -18%

FY2020 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 2020, we have also furthered the staggered introduction of precut roof slate, siding, and Kizure panel materials that have been measured and processed on sites. In fiscal 2021, we will expand the area of these initiatives to branches throughout Japan. The reductions in the weight of industrial waste through precuts is tremendous. Sumitomo Forestry expects emission reductions of 170 kg for roof slate per building, 550 kg per building for siding and 80 kg for Kizure Panels per building.

Due to differences in the amount of industrial waste emissions originating from factors such as the location, region and specifications of each construction site in fiscal 2021, we calculated the appropriate amount of industrial waste emissions and created the targets of appropriate amount of industrial waste emission for each branch. By setting proper industrial waste emission targets, Sumitomo Forestry will work to reduce waste emissions by renewing the thinking on construction sites, engaging in awareness-raising initiatives and analyzing the amount of industrial waste emissions while also planning and executing improvement plans.

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 95.2% in fiscal 2020 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 in fiscal 2021.

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 five prefectures of Kanto (Metropolitan Tokyo, Kanagawa, 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 even in regions outside the metropolitan area. Currently, 62 of 63 offices and branches throughout Japan have begun operations. In the same way data is collected by the Metropolitan Area Recycling Center, we can also gather data on the level of waste produced throughout Japan. The analysis of this data helps us reduce waste because we can discover trends in the amount and type of waste according to building specifications and construction conditions in each region.

Efforts at Demolition Housing Sites

Sumitomo Forestry was promoting resource recycling even before the enactment of the Construction Material Recycling Law implemented in 2002 by ensuring that materials were properly sorted during demolition prior to the construction of a new house and that waste remained sorted for processing afterwards. Since the enactment in 2002, the Company has recycled the items required under the Law (wood waste, concrete, etc.), sorting them at the sites where the waste is generated. In recent years, demolition work of housing built using construction materials containing asbestos has increased, and reform bills related to asbestos were also enacted in 2020. Sumitomo Forestry especially strives for uncompromising compliance to removal method, processing guidance and management of construction materials containing asbestos.

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 our demolition partners.

Launch of Industrial Waste Management Centers

Sumitomo Forestry opened three industrial waste management centers throughout Japan in fiscal 2021. Managers specializing in industrial waste management make every effort to eliminate industrial risks throughout Japan by consolidating highly accurate management processes.

These management processes include precise process confirmations and deadline management from electronic manifest registration of industrial waste produced throughout Japan through the final disposal obligations of the entity producing the emissions. These management practices strictly adhere to laws and regulations, such as checking information registered in the electronic manifest against the outsourcing contract and updates to outsourcing contracts.

Remodeling and Renovation Business Initiatives

We are working to reduce waste generated on remodeling and renovation sites by using reusable protective materials.

Our Group also strives to effectively use resources, such as the initiative to operate a material recycling route to reclaim wood waste from metropolitan areas as raw materials for particle board that started in fiscal 2014.

In the three major metropolitan areas with the most emissions, we have established construction departments to supervise the entire area and provide guidance and education on overall industrial waste management and ways to improve their recycling rate. The recycling rate from January to December 2020 was 72.3%. In addition to thorough sorting on site in the future, we plan to bring in even more waste treatment contractors with high-level glass and ceramic recycling capabilities.

Work 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.

Education for New Construction and Demolition Contractors

Sumitomo Forestry provides education to new construction contractors and conducts comprehension tests about industrial waste. Demolition contractors report about industrial waste to each office and branch from the start of demolition work to its completion as a construction management record according to a manual. Each office and branch verifies these construction management records and provides guidance for corrective actions if any inconsistencies are found.
