Commitment to CSR

Low Carbon Society

The Chiyoda Group carries out plant construction through engineering, procurement and construction (EPC) and other activities in Japan and overseas. In doing so, we respect the local traditions and cultures of each country, foster communication and contribute to prosperous lifestyles.

 

In the booklet Legacy for the 21st Century issued in 1972, Chiyoda declared that it would take the initiative to solve energy and environmental problems. Chiyoda Group companies have remained true to this spirit in constructing plants in Japan and around the world for many years.

Creating the Future with Chiyoda's Energy and Environmental Technologies

 

Below are examples of environmental technologies we are currently promoting.

As a joint project, Chiyoda is developing the domestic Gas to Liquid (GTL) technology to produce clean, environmentally friendly fuel.

Contributing to Stable Energy Supply and Greenhouse Gas Reduction
Gas to Liquids (GTL) Technology Using CO2 as a Raw Material

A demonstration test project aimed at establishing domestic Gas to Liquids (GTL)1 technology is moving ahead in Niigata Prefecture, with a production rate of 500 barrels per day. This is a joint project between the Japan Oil, Gas and Metals National Corporation and the Nippon GTL Technology Research Association composed of six private companies: INPEX Corporation, Nippon Oil Corporation, Japan Petroleum Exploration Co., Ltd., Cosmo Oil Co., Ltd., Nippon Steel Engineering Co., Ltd. and Chiyoda.
Fuels produced using GTL technology are promising as clean, environmentally friendly fuels because they are free of sulfur and aromatic compounds. Existing GTL technology uses natural gas as a raw material, but CO2 must be removed. However, a feature of the Japan-GTL technology is that it employs Chiyoda’s unique CO2 reforming catalyst that allows natural gas containing significant amounts of CO2 to be used as a raw material. This breakthrough technology opens a path to new, clean fuels using natural gas, which is found widely throughout the world, as a raw material.
The demonstration plant, completed in April 2009, is currently undergoing a two-year demonstration operation. We are looking at practical applications for this unique GTL technology to secure a stable energy supply while contributing to the global environment.

1. Gas to Liquids (GTL) Technology: Technology in which natural gas passes through a syngas (hydrogen and carbon monoxide) to become liquid hydrocarbon fuel.

 

i WaterTMSystem

Chiyoda has developed a next-generation water recycling system, the i WaterTM System, as a solution to cope with increasingly severe water pollution and water shortages. This recycling system purifies and reclaims industrial wastewater from petroleum and chemical plants for re-use in plants as cooling water or boiler feed water. The reclaimed water can be supplied in the volume and quality that users require. One project related to this system is an order received in March 2011 from Marafiq, a power and water utility company in Jubail Industrial City, Saudi Arabia, to determine the feasibility of treating and re-using industrial wastewater in the industrial park. Through pilot tests and other processes, Chiyoda is aiming to contribute to the water environment in the industrial park by designing and proposing an i WaterTM System. Chiyoda will continue to aggressively promote the i WaterTM System for effective use of water resources.

Biodiversity Initiatives

In the fiscal year ended March 2011, Chiyoda set forth and carried out initiatives to implement basic principles on preserving biodiversity (below).

  1. Adhere to agreements and laws concerning biodiversity
  2. Conduct biodiversity-conscious corporate activities
  3. Raise employee awareness of biodiversity preservation
  4. Proactively disclose information on initiatives

On-site initiatives at major overseas projects are covered in the Group CSR Report 2011.
As an internal initiative, Chiyoda aggressively makes environmental proposals to customers in engineering, procurement and construction work on plants and facilities. We made 263 such proposals for domestic and overseas projects in the fiscal year ended March 2011.

Participation in Local Forest Preservation Activities
As one of its biodiversity preservation initiatives, Chiyoda has joined Foundation Kanagawa Trust Midori to support employees’ forest preservation activities. We also convey information to employees about biodiversity initiatives via the Chiyoda corporate intranet.
