In order to advance the recycling of resources, the Company first defines the “zero emissions” target to be pursued, and works to achieve this target.
The Group will not simply incinerate or bury in landfills all of the industrial waste generated from its plants in Japan and new housing construction sites.
Based on this definition, the Group will continue zero emissions activities at domestic manufacturing facilities, and initially aims to achieve zero emissions at new construction sites1 in the capital area by December 31, 2012.
The recycling rate at the end of fiscal 2011 was 89.3%.
Sumitomo Forestry identifies the volume of waste generated at new housing construction sites and works to reduce this volume, while also preventing inappropriate disposal. The Company is also working towards the achievement of zero emissions by promoting the processing of industrial waste by utilizing “inter-region recovery and recycling certification system1.”
Within the items targeted for zero emissions, a recycling rate of 86.8% was achieved for waste generated at new housing construction sites.
On December 8, 2010, Sumitomo Forestry obtained industrial waste certification from the Minister of the Environment based on an inter-region recovery and recycling certification system. This system enables companies designated by Sumitomo Forestry (such as materials suppliers) to be registered as “persons engaged in the collection or transportation of industrial waste,” so that approval for industrial waste treatment is not required in relation to the collection and transportation of the Company’s waste. This makes it possible to collect industrial waste by utilizing specialist waste collection/transportation vehicles and trucks returning to base after having transported homebuilding materials to new construction sites, and to consolidate waste collection at collection centers registered in the inter-region certification system.
The consolidated waste is entrusted directly to treatment contractors that can process it with zero emissions, or is transported to in-house facilities where high-level separation can be carried out. After sorting, the waste is entrusted directly to third-party recycling facilities or is sold at a profit.
The Group continues its efforts to limit the generation of industrial waste through the use of precut timber, reducing the amount of packaging materials used. Examples of efforts in this area include setting the dimensions of the eaves to minimize the waste generated when producing precut timber for soffits (the underside of eaves) and end cuts from materials used to finish the underside of the home’s eaves. In addition, the practicality and costs of pre-cutting ceramic roof tiles, sidings, and panels for exterior reinforcement are being investigated for future deployment.
Sumitomo Forestry will continue its efforts to increase its recycling rate at its business sites throughout Japan and achieve zero emissions through recycling at recycling centers that utilize the inter-region recovery and recycling certification system. The Company’s Capital Area Recycling Center is working toward achieving even finer separation of waste at the same time as developing materials recycled from in-house production and utilizing them in the construction of new houses.
Zero Emissions was achieved at the plants of Sumirin Agro-Products Co., Ltd. in fiscal 2011 as a result of its continuing efforts to eliminate emissions. The plants operated by Sumitomo Forestry Crest Co., Ltd. have also been working to reduce industrial waste by searching for and implementing new methods of processing difficult-to-recycle waste, but despite these efforts their overall result fell slightly below the target for fiscal 2011.
