In September 2009, in order to reduce greenhouse gas emissions by 46.5 tons over five years, Taisei Rotec installed 170 “reFbo” high efficiency light reflectors manufactured by Daiwa House Industry Co., Ltd. to serve as the electric lights of its Kanto branch. To create a credit for 22 tons of planned emissions reduction, Taisei Rotec, aided by Daiwa House Industry, applied to the Tokyo Metropolitan Government for an “Emissions Credit for Small- and Mid-size Companies” in August 2010, making its appeal to receive the firstever credit authorization. If this credit is authorized, it will be sold on the Japan Climate Exchange (JCX), thereby contributing to greenhouse gas emissions reductions throughout the Tokyo area.
As part of its initiatives to reduce by applying the 3R* to waste, Taisei U-Lec adopts resin formworks for the joint formworks of precast reinforced concrete panel components at construction sites and limits the volume of waste generated. The company also implemented a 4S (seiri (orderliness), seiton (neatness), seiketsu (tidiness), and seiso (cleanliness)) program at construction sites in accordance with the basic policy of "working safely and creating worry-free and pleasant work environments."
*3R: Reduce waste generation, Reuse materials recovered from waste, Recycle waste
Yuraku Real Estate is introducing a remote control with energy display as an environmental initiative in the real estate business. The remote control displays the amount of gas and the volume of hot water used in the home. By making energy usage visible, families can work to conserve energy.
Muddy water generated at construction sites is processed using chitosan, a natural flocculant. Chitosan is a natural substance derived from crab and shrimp shells. It is a biodegradable and environmentally-friendly flocculant. In addition, sludge that contains chitosan can be effectively used as a base material for cultivation, reducing industrial waste processing costs.
In road construction, a greater amount of fossil fuels are used when manufacturing asphalt mixtures than when laying pavement. Because of this, asphalt mixing plants have long collected data on fuel usage and taken measures to reduce usage in order to cut costs. The result is also a reduction in carbon dioxide. The data that has been collected over many years is now being used in environmental management activities in for the form of various measures to reduce resource use and save energy at asphalt mixing plants.
We are also taking immediate measures at our asphalt mixing plants in response to the revised Law Concerning the Rational Use of Energy Law and the revised Tokyo Metropolitan Environmental Protection Ordinance coming into effect this year.
Taisei Rotec is committed to undertaking ongoing CSR activities and fulfilling its corporate social responsibilities as a major player in the paving industry and a member of the Taisei Group.
※The Taisei Rotec Tokyo Aomi Asphalt Mixing Plant and Tokyo Rinkai Recycling Center is equipped with cutting-edge equipment. Used road material is brought here and recycled to make new paving material.
