Reduction of Raw Materials Usage Amount

Chiyoda engages in plant construction and has proclaimed to work on 'optimization of resource・ energy consumption, detoxication・reduction of volume・resource recovery of emissions and waste and carbon management towards low carbon society' in the SQE basic policy and the initiative to reduce raw materials usage amount is extremely important. In addition to working on 3R （Reduce>Reuse>Recycle）in accordance with Basic Act on Establishing a Sound Material-Cycle Society, we also strictly work on recycling recyclable resource materials and designated construction materials in accordance with Act on the Promotion of Effective Utilization of Resources and Construction Material Recycling Act. We also work on reduction of raw materials usage amount through EPC business.

Also as a measure leading to reduction of environmental load, we have been working on 'optimization of resource・energy consumption' and as part of it, we are promoting green procurement* and aiming to contribute to the realization of'basic harmony between global environment and human development or in other words sustainable development' and thus contributing to the society.

• Green procurement consists of green purchase and green procurement 
  Green purchase：An activity to choose from environmentally friendly products (recyclable, long time usable, use of recycled raw materials etc. ) when an organization choose products and services (stationery, equipment, utilities etc.) that they use for themselves, not only by price, quality or delivery deadline.  
  Green procurement：When an organization choose parts and materials used for its products and services they choose environmentally friendly products and not only by price, quality or delivery deadline.

Reduction of Waste

As our initiative to reduce waste, We implemet 'detoxication・reduction of volume・resource recovery of emissions and waste' in SQE basic policy thoroughly. As for industrial waste generated from construction sites, overall plan to control construction byproducts generated from that site is created and separate collection of industrial waste is ensured and recycling is attempted、Efforts are made to select intermediate disposal companies with resource recovery facility or with business partner of resource recovery facility, when selecting disposal companies. The recycling rate, incineration rate and landfill rate from 2018 onwards are moving between 90～95%、0～0.6%、5～10% respectively.
