Environmental Conservation Activities by Group Companies

Housetec Inc.

Dissemination of Energy-Effi cient Products under Green Product Assessment System

 In order to reduce environmental impact at each stage of the product lifecycle, Housetec conducts green product assessment to approve products satisfying a certain level as green products, and proactively develop, manufacture and sell such products.

 As of the end of fi scal 2016, Housetec achieved its target, the sales ratio of 99%, for green products.

 Through green product assessment, which focuses on such items as the reduction of component weight and the use of recycled materials, Housetec strengthens its efforts to develop and manufacture products with less environmental impact throughout their lifecycle.

Voluntary Reduction of Emission of Chemical Substances

 Housetec considers that reducing emission of chemical substances is one of the major issues in efforts for mitigating environmental impact.

 Housetec voluntarily controls the purchase, use, disposal and manufacture as products of such substances as acetone and ethyl acetate, in addition to those substances covered under the PRTR Act,* in order to reduce their emissions into the air.

Reduction of CO2 Emissions

 In consideration of the emission reduction goals set in the Kyoto Protocol, Housetec established its goal of reducing CO2 emissions by 42% from the level of fiscal 1990 by 2016 and has been promoting relevant measures accordingly, such as the enhancement of the energy effi ciency of its production facilities.

 In fi scal 2016, CO2 emissions were reduced to 7,800t, exceeding the initial goal of 10,200t. Housetec will continue its efforts for reducing CO2 emissions and also endeavor to contribute to preventing global warming from the perspective of product lifecycle as a whole and not merely focus on its production facilities, with the help of customers.

* CO2 emission intensity = CO2 emissions / sales (compared to the fi scal 1990 level)

Project White Co., Ltd.

Contribute to the Creation of Recyclingoriented Society through Collection and Recycling of PCs

 Upon the amendment of the Act on the Promotion of Effective Utilization of Resources, Project White started to promote the collection and recycling of its PCs disposed of by individual customers with the aim of contributing to the creation of a recycling-oriented society. Customers' applications for disposal of Project White's PCs are all accepted at the Tsukumo Support & PC Recycling Center and collected PCs are sent to the recycling facilities for proper treatment in compliance with relevant laws.

Yamada SxL Home Co., Ltd.

Promote the Acquisition of ISO14001 Certification

 In October 1997, Yamada SxL Home acquired ISO9001 Certification, the international standard for quality management systems, for the Tsukuba plant and Yamaguchi plant of its subsidiary, SxL Juko. In October 1998, these plants also acquired ISO14001, the international standard for environmental management systems. They undergo periodical assessment to ensure their quality management systems and environmental management systems, and have endeavored to provide high quality houses and environmentally-friendly houses that satisfy customers. A demand controller was introduced to the Yamaguchi plant in 1998 and to the Tsukuba plant in 2011, and efforts are being made to enhance energy efficiency through the reduction of CO2 emissions in business activities. Efforts for reducing gas and gasoline use and emissions of general waste, industrial waste and dioxin, etc. are also being continued at these plants. Buildings wherein business offices of Yamada SxL Home are located firmly comply with laws and regulations relating to waste disposal, cleaning, exhaust, effluent, soil contamination, groundwater contamination, noise, odor, and greenhouse gas emissions. Additionally, the company periodically conducts air environment measurement and statutory inspection of fire protection equipment, thereby striving to create a proper working environment.

Wood Use in Consideration of Conservation of Forestry Ecosystems

 In order to conserve the global environment and sustainably develop forests, the Yamada SxL Home Group has endeavored to secure the legality of wood they use for structural members and establish a traceability system. In fiscal 2016 as in the previous fiscal year, such efforts were made for structural members for the SxL method (method using wooden adhesive panels), which accounts for 90.6% of the company's housing business (detached houses).

 Wood used for the SxL method is divided into dimension lumber (two by four lumber), plywood, and structural panels, and is further divided into dimension lumber for adhesive panels, dimension lumber for laminated lumber, unprocessed dimension lumber to be used for rafters, plywood for adhesive wall panels, plywood for adhesive fl oor panels, sheathing plywood to be used for roofi ng boards, and Oriented Strand Boards (OSBs). Dimension lumber is made of Spruce Pine Fir (SPF), Hem Fir (HF), and Douglas Fir (DF), all of which are FSC certifi ed lumber imported from North America.

Wall panels are made of Russian larch proved to have been legally logged by the Japan Lumber Importers' Association. Part of the sheathing plywood uses Douglas Fir (DF), and OSBs mainly use aspen lumber, both of which are FSC certifi ed lumber.

A Class on the Environment at the National Museum of Nature and Science

 On Saturday, April 1, 2017, Azuma Metal held a class titled "Let's Learn the Mechanism of Metal Recycling! Art Works of Unique Figures Using Scraps" at the science navigation corner in the National Museum of Nature and Science in Ueno. As it was during school spring vacation, visiting children included those from distant areas, such as Kyushu.

 The class aims to provide children with an opportunity to actually touch scraps to make up unique figures and see and feel differences in color and weight of various kinds of metals, thereby making them more interested in resource recycling. Additionally, after explaining metal recycling by showing a video of recycling of industrial waste and home appliances, and playing quizzes, participants enjoyed creating art works using recycled metals.

Corporation and Inversenet Co., Ltd. Small home appliances that could not be reused at C.I.C. Corporation and Inversenet are sent to recycling plants of Azuma Metal, processed into recycled goods by material (resources and raw materials), sold to refi ning companies, etc., and used for making new products.
