The Sumitomo Forestry Group makes efforts in attaining zero emissions and reducing industrial waste generated at the same time as promoting reuse and recycling for each operational process in accordance with the Sumitomo Forestry Group Environmental Policies in order to build a sustainable environment. In fiscal 2018, overall Sumitomo Forestry Group emissions volume was up 6.9%. However, new housing construction site waste processing operations under expanded areas covered by the inter-region recovery and recycling certification helped reduce the final processing volume by 11.0%. We will continue to strive to effectively use resources in the future.

Initiatives to Achieve Zero Emissions

The Sumitomo Forestry Group promotes zero emissions initiatives by mitigating generation and reusing and recycling of industrial waste with intention to reduce the environmental burden and enhance effective use of resources. The Group’s Mid-Term Environmental Management Plan ended in fiscal 2014 defined “zero emissions” as no incineration or landfill of industrial waste (recycling rate of 98% or more) generated by domestic manufacturing facilities and new housing construction sites.

Based on this definition, the Group achieved zero emissions at domestic manufacturing facilities (Sumitomo Forestry Crest Co. and Sumitomo Forestry Landscaping [formerly Sumirin Agro-Products Co.]) in fiscal 2009. As for new housing construction sites, including exterior landscaping, the Group achieved zero emissions in the Tokyo metropolitan area in fiscal 2012.

Since fiscal 2015, the Group has been adhering to the former Mid-Term CSR Management Plan with its target year of fiscal 2020 while continuously working towards zero emissions. From fiscal 2019, we are working to achieve zero emissions in keeping with the new Mid-Term Sustainability Targets, with a target year of fiscal 2021. 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.

Efforts at New Housing Construction Sites

We work to reduce waste generated at Sumitomo Forestry’s new housing construction sites. At monthly meetings of our Waste Reduction Working Group, leaders of sub-groups raise and share issues while managing progress toward meeting targets. Efforts to reduce waste have included the use of the bare minimum necessary packaging materials and reusable protective material for flooring. Moving forward, we plan to promote the use of precut construction materials of all kinds for further progress in waste reduction.

In the Tokyo metropolitan area, the Company obtained inter-region recovery and recycling certification, whereupon we established the Metropolitan Area Recycling Center, and implemented streamlined sorting of waste. In fiscal 2018, new housing construction site waste processing operations under expanded areas covered by the inter-region recovery and recycling certification helped improve the recycling rate by 1.7% from the previous year.

Power Generation Business Initiatives

In power generation business operations, incineration ash emitted by biomass boilers is blended with quicklime for reuse primarily as a forest roadbed material. In fiscal 2018, it was manufactured under the product name Rovander, and received approval as a Hokkaido Government-certified Recycled Product.

Renovation Business Initiatives

We are working to reduce waste generated by renovation sites by using protective materials as well as other measures to mitigate waste generation. In fiscal 2014, Sumitomo Forestry Home Tech Co., Ltd. began recycling wood waste materials generated at its renovation sites. Our efforts to use resources effectively include recycling wood waste as raw material for particle board. The recycling rate in fiscal 2018 was 74.3%. The Mid-Term Sustainability Targets set the target of an 80% recycling rate to be achieved by fiscal 2021.

Initiatives at Overseas Manufacturing Plants

We are working toward zero emissions at our five main manufacturing companies outside Japan*. Kutai Timber Indonesia collects wood waste generated during the particle board manufacturing process and reuses it as boiler fuel or in wood building materials.

In fiscal 2018, the total volume of waste produced was 240,283t, with a final waste processing volume of 6,002t and a recycling rate of 97.5%. The 2021 Mid-Term Sustainability Goals set the target of a 98% recycling rate.

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.

The recycling rate* for concrete and metal waste was almost 100% in fiscal 2018, as it was the previous year. A 100% recycling rate was achieved for wood waste through measures including the thorough removal of extraneous matter. The 2021 Mid-Term Sustainability Goals set the target of a 98% recycling rate for construction materials specified under the Construction Material Recycling Law and metals as well as at construction areas that the Law does not apply to (total floor area of 80m² or less).

* Recycling rate calculation includes metals in addition to construction materials specified under the Construction Material Recycling Law (concrete, asphalt-concrete and wood waste) and metals.

Education for New Construction and Demolition Contractors

Demolition contractors report about industrial waste to the Housing and Construction Division from the start of demolition work to its completion, recording the work according to a manual. The Housing and Construction Division comprehensively checks these reports and, if there are any inconsistencies, education and comprehension tests about industrial waste are conducted for new construction contractors with monthly construction contractor meetings as an important management branch to confirm their capabilities.

Recycling of Wood Resources into Chips

The Sumitomo Forestry Group contributes to resource recycling through its wood chip operations, whereby offcuts generated during the timber milling process and wood waste from new housing construction and demolition sites are turned into wood chips to be used as a raw material for products such as paper and particle board, and also as a fuel for power-generating boilers or other equipment.

In fiscal 2019, we aim to further increase the volume we handle for use as fuel in order to meet the growing demand for fuel used in biomass power generation.

Effective Utilization of Used Activated Carbon from Water Purification Plants

The Tokyo Metropolitan Government (TMG) Bureau of Waterworks uses an advanced water treatment system combining ozonation and the use of biological activated carbon.

The Agro-Products division of Sumitomo Forestry Landscaping (formerly Sumirin Agro-Products Co.) is making effective use of this used activated carbon to develop and market potting media for agriculture and horticulture and a soil improvement agent for greening. Joint research conducted with the TMG found that these items were effective in promoting plant growth, and the two parties applied for a joint patent based on the research results.

The amount of used activated carbon in fiscal 2018 was 3,620m³, up 44.8% compared to the previous fiscal year. In fiscal 2019, Tane Baido and Karuido products that use activated carbon are expected to perform favorably with an estimate of 4,300m³, an 18.8% increase compared to fiscal 2018.
