We 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 recycling-oriented society. The amount of emissions from the Sumitomo Forestry Group as a whole declined by 8.0% in fiscal 2017 compared to the previous fiscal year. We will continue to strive to effectively use resources in the future.

Initiatives Towards Zero Emissions in Japan

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 simple 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., Ltd. and Sumirin Agro-Products Co., Ltd.; current: Sumitomo Forestry Landscaping Co., Ltd. agricultural business) 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.

In fiscal 2015 onwards, adhering to Sumitomo Forestry Group Mid-Term CSR Management Plan with its target year being fiscal 2020, the Group continuously works towards zero emissions at new housing construction sites and higher recycling rates at renovation sites and sales of building-related materials. Strict separations of waste according to materials are essential for recycling. Therefore, the Group will raise employee awareness on and enforce appropriate waste disposal process altogether to improve the overall recycling rate and achieving the rate of 98% by fiscal 2020.

Going forward, the Group will analyze the content of the generated waste and the extent to which it is being recycled at new and other construction sites, and develop environmentally conscious products, adopting rational design techniques and ensure that waste is thoroughly sorted at production sites to achieve zero emission.

Improving Recycling Rate at Construction Sites of New Houses

At Sumitomo Forestry’s new housing construction sites, strict sorting of industrial waste generated at the sites has been implemented as part of the effort to increase recycling. In the Tokyo metropolitan area, the Company obtained “inter-region recovery and recycling certification” from Ministry of Environment in 2012, established the Metropolitan Area Recycling Center, and implemented streamlined sorting of waste. Additionally, as to in other areas, the Company utilizes inbound material transporters in collecting and transferring waste.

Initiatives Other than New Housing Construction Sites or Domestic Plants of Building Components

At waste-generating enterprises such as sites of renovation and housing materials sales, initiatives to reduce amounts of waste generated are implemented at a department level. We are working to reduce waste generated by renovation sites by using protective materials as well as other measures to mitigate waste generation. The recycling rate in fiscal 2017 was 76.2%.

Recycling wood waste materials from renovation sites

In fiscal 2014, Sumitomo Forestry Home Tech Co., Ltd. began recycling wood waste materials generated at its renovation sites. The recycled wood waste is used as raw materials for particle board, and is processed into wall surfaces, entrance hall storage areas and other products at the Sumitomo Forestry Crest Co., Ltd. manufacturing site. These interior materials are then used at the renovation sites.

Initiatives at Domestic Plants of Building Components

Sumitomo Forestry Crest Co., Ltd. managed to achieve zero emissions (recycling rates of over 98%) again at all plants in fiscal 2017 as a result of each plant continuing with efforts to reduce waste emissions, for example by tightening the sorting of industrial waste and selling it for a profit.

Initiatives for Zero Emissions at Overseas Manufacturing Facilities

The five main manufacturing companies outside Japan*, besides complying with local laws, are advancing initiatives based on the Sumitomo Forestry Group’s definition of zero emissions. For example, in Indonesia, PT. Kutai Timber Indonesia collects wood waste generated during the particle board manufacturing process and reuses it as boiler fuel or in wood building materials.

The total emissions was 199,308t in fiscal 2017, which is a 19% reduction compared to the previous fiscal year (246,210t).

We will continue to aim to achieve zero emissions in the future.

Proper Disposal of Demolition Waste

Sumitomo Forestry was promoting resource recycling even before the enactment of the Construction Material Recycling Act 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 Act (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 2017, as it was the previous year. A 100% recycling rate was achieved for wood waste through measures including the thorough removal of extraneous matter. We strive for appropriate processing while developing recycling routes for roofing tiles, glass, ceramics, gypsum board and other composite waste for even further improvement of recycling rates.

Education for New Construction and Demolition Contractors

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

Looking at the volume of wood chips handled in fiscal 2017, raw material applications (derived from lumber manufacturers) showed a better balance in supply and demand of raw materials for paper making than the previous fiscal year. On the other hand, the volume of wood chips for fuel applications (derived from demolition) increased compared to the previous fiscal year due to active efforts to increase the share by cultivating avenues to new suppliers as well as existing suppliers of fuel for FIT (fixed price purchasing system for renewable energy) power generation.

In fiscal 2018, the Group expects to handle the same volume of wood chips used as a raw material for paper and particle board as in fiscal 2017. In addition, the Group expects that the volume of wood chips it handles for use as fuel will further increase through meeting 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.

Group company Sumirin Agro-Products Co., Ltd. (current: Sumitomo Forestry Landscaping Co., Ltd.) 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 2017 was 2,500m³, which increased 33.2% compared to the previous fiscal year. In fiscal 2018, Tane Baido and Karuido products that use activated carbon are expected to perform favorably with an estimate of 3,962m³, a 58.5% increase compared to fiscal 2017.
