Initiatives Towards Group-Wide Zero Emissions

Aiming to build resource-circulating society, the Sumitomo Forestry Group makes efforts in attaining zero emissions and reducing industrial waste generated at the same time. The Group promotes zero emissions initiatives by mitigating generation and reusing and recycling of industrial waste with intention to reduce environmental burden and enhance effective use of resources. The Group’s Medium-Term Environmental Management Plan ended in fiscal 2014 defined “zero emissions” as no incineration or landfill of industrial waste generated by domestic manufacturing facilities and new 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.) in fiscal 2009. As for new construction sites, including exterior greening, the Group achieved zero emissions in the Tokyo metropolitan area in fiscal 2012.
In fiscal 2015 onwards, adhering to Sumitomo Forestry Group CSR Mid-Term Plan with its target year being fiscal 2020, the Group continuously work towards zero emissions at construction sites of new houses 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, in addition to maintaining zero emissions at domestic manufacturing facilities, with regard to new construction sites, the Group will analyze the content of the generated waste and the extent to which it is being recycled, and continue striving for zero emissions, such as by developing environmentally conscious products, adopting rational design techniques and ensuring that waste is thoroughly sorted at production sites.

Improving Recycling Rate at Construction Sites of New Houses

At Sumitomo Forestry’s construction sites of new homes, 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.

Initiative for Reduction of Industrial Waste Generated at New-Home Construction Sites

When we construct new houses, generating waste is unavoidable.
The Sumitomo Forestry Group has made continued efforts to minimize waste and treat waste properly. In fiscal 2015, we focused on reducing waste with the 3Rs (reduce, reuse and recycle) principle.
In July 2014, we set up the Waste Reduction Working Group comprising representatives from the product development, materials, logistics, design, production and environment divisions. The working group has held monthly meetings, and developed and implemented specific measures.
The working group analyzed the wide variety of waste generated at new housing construction sites and found that three types of wastes account for two thirds of the total waste. The three types are packaging materials (cardboard), wood waste and waste gypsum board and have become the focus of the reducing effort. For instance, we are taking drastic measures with the packaging of interior materials manufactured by our Group company, Sumitomo Forestry Crest Co., Ltd. We expect to see the results of our reduction efforts in fiscal 2016.
We have also changed the cost bearing mechanism for waste treatment from pay according to the scale of the house to pay per amount of waste actually generated during the construction of a new house. We are raising awareness of workers at construction sites by linking the amount of waste and the cost and providing feedback in the form of waste emission data.
The Sumitomo Forestry Group upholds the 2020 target in its CSR Mid-Term Plan to reduce the waste generated at the new house construction sites by 30% from the fiscal 2016 level. In fiscal 2015, the disposed industrial waste per new house has decreased by 2.5% from the fiscal 2013 level.

Initiatives at Sites Other than Construction of New Homes

At other business sites that release CO2 such as sites of renovation and housing materials sales, initiatives to reduce amounts of waste generated are implemented at a department level. For renovation sites, using protective materials attribute to mitigating waste generation. In fiscal 2015, the recycling rate at the sites other than construction sites of new homes was 70.2%.

Initiatives at Domestic Manufacturing Facilities

Sumitomo Forestry Crest Co., Ltd. and Sumirin Agro-Products Co., Ltd. managed to achieve zero emissions (recycling rates of over 98%) again at all plants in fiscal 2015 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 six main manufacturing companies outside Japan*1, 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.

In fiscal 2015, three of the six companies— Alpine MDF Industries Pty Ltd., Nelson Pine Industries Ltd., and Vina Eco Board Co., Ltd. —achieved zero emissions. The other three companies: PT. Kutai Timber Indonesia, PT. AST Indonesia, and Rimba Partikel Indonesia will make additional efforts to reduce waste emissions, reuse materials and ensure thorough sorting and collection.

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 2015, as it was the previous year. A 100% recycling rate was achieved for wood waste through measures including the thorough removal of extraneous matter. Efforts will now be made to develop recycling routes for roofing tiles, glass, ceramics, gypsum board and other composite waste for even further improvement of recycling rates.

Operations at the Metropolitan Area Recycling Center

In December 2010, Sumitomo Forestry obtained the National Permit System for waste processing1 from the Ministry of the Environment. This made it possible to use the return journey of trucks transporting materials to new housing construction sites to recover waste and collect it at relay centers registered as collection points under the National Permit System.

The Company took advantage of the system to establish the Metropolitan Area Recycling Center with capability for advanced sorting of waste in Kazo, Saitama Prefecture. The center started operating in fiscal 2012 and covers all areas of the seven prefectures of Tokyo, Kanagawa, Chiba, Saitama, Ibaraki, Tochigi and Gunma. Since fiscal 2015, the Group has expanded its efforts for waste recovery under the National Permit System to 21 branches in 20 prefectures outside the Tokyo metropolitan area. The establishment of the Metropolitan Area Recycling Center enabled collection and analysis of waste-associated data. Through provision of the data such as waste generation by product, specification, and building contractor for diverse functions, for example, product development, materials, designs, production, and logistics, the Company aims to realize reduction of waste to be disposed of.

Strengthening Waste Management through Construction Process Management Systems

Sumitomo Forestry has built a system whereby the emission of waste at sites and the delivery status of waste to waste treatment plants can be confirmed on a mobile phone. By checking the images collected in the system against the categories and volumes of demolition waste lodged by waste processors based on electronic manifests, the Company has strengthened its system for managing demolition waste.
By the end of fiscal 2013, introduction of this system had been completed for almost all demolition contractors, allowing the Company to check that waste emitted from the Company’s sites is being taken properly to waste treatment plants.

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 a 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.

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 2015, the Group began dealing in wood chips for export and so there was an increase in the volume of wood chips used as raw material (from demolition waste) compared to the previous fiscal year. On the other hand, the amount of raw materials declined as a backlash from the last-minute surge in demand prior to the consumption tax increase, and so the volume of wood chips for use as fuel (from demolition waste) also decreased.
In fiscal 2016, the Group expects to handle the same volume of wood chips used as a raw material for paper and particle board as in fiscal 2015. 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. The system used as much as around 7,800m3 of activated carbon in fiscal 2014 for reduction of organic matter and deodorization.
Group company Sumirin Agro-Products 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.
In fiscal 2015, as a result of decreased purchase of used activated carbon from the water purification plants, the amount Sumitomo Agro-Products used remained 1,886 m3 that is 30% less than fiscal 2014. In fiscal 2016, this volume is expected to bounce back to 1,929 m3 or by 2% compared to fiscal 2015.
