Sustainable Water Usage

One of Sojitz’s Key Sustainability Issues (Materiality) calls for our company to “develop, use, and supply sustainable resources.” This includes water resources, for which experts predict securing a stable supply will only grow harder in the future due to climate change.

Additionally, the Sojitz Group Environmental Policy calls for business practices that work towards the conservation of natural resources, including water, as well as waste reduction and recycling.

On this page, we introduce some of the initiatives based on these policies that Sojitz Group is undertaking with consideration for sustainable water use.

Conducting Water Risk Surveys

Sojitz Group uses Aqueduct, a tool for analyzing water risk developed by the World Resource Institute, to monitor the status of water-stressed regions in which Sojitz conducts business.

●Method

  • (1)Identifying risks:
    We comprehensively evaluate sector-specific risks and regional risks (using the Aqueduct indicators "Water Stress," "Water Depletion," "Interannual Variability," and "Seasonal Variability") for Sojitz Group companies, which account for over 99% of the amount of water used by the entirety of Sojitz Group.
    risk
  • (2)Addressing risks we have identified:
    We hold consultations with Group companies to ascertain the status of their efforts to address risks we have identified.

●Results
We have confirmed that there are no problems with the measures taken to address risks at the business sites of Group companies. We have also confirmed that there are no problems with the system to respond to risks and report information to Tokyo HQ in the event that a risk should materialize.

Although some coal mines we operate in Australia are designated by Aqueduct as areas with water stress, we do not expect this water risk to materialize as we have been guaranteed a priority supply of water for industrial use over other businesses.

Drought

●When deliberating new investments and loans, we confirm the risk of damage from natural disasters, including regional water risks, in order to enhance our tolerance for physical risks.

Also, moving forward, we are considering using official hazard maps and addressing future physical risks other than water risk, such as rising temperatures and changes in planting areas due to climate change. We will also continue to address physical risks.

Initiatives to Reduce Water Consumption

= Initiatives within our Textile Business =
Water is an essential part of textile processing. The following describes one of Sojitz’s current initiatives to reduce water usage within our textile operations.

Sojitz Group company Daiichibo Co., Ltd. has obtained ISO14001 and implemented a number of initiatives dedicated to greater consideration for the environment. Among these initiatives are efforts which aim to reduce water consumption.

Daiichibo was founded in 1947. Little more than just a spinning factory at that time, it later expanded to include a knitting factory in 1972 and a dyeing factory in 1973, creating an integrated production process including spinning, knitting, and dyeing. (This would later be expanded to include sewing, achieving total integration of the production line.).

Generally, spinning factories are extremely hot inside due to the heat emitted by the spinning machinery. Air conditioning is essential to ensure stable product quality and create an environment amenable to workers. This air conditioning uses mass volumes of water.

The dyeing factory also uses a lot of water. Before dyeing the knitted fabric, it needs to be washed of starches and oils, and the liquid dye itself needs to be boiled at a high temperature.

Rather than dispose of the water used to regulate the temperature in the spinning factory, Daiichibo has it drained into a fire cistern, then rerouted to the dyeing factory. In this way, not a drop is wasted.

This initiative shows consideration for effective water usage, having it play a key role in air conditioning, fire safety, and dyeing. Through these efforts, Daiichibo is aiming to cut water usage by 3% year-on-year.

= Initiatives within our Fertilizer Business =
Sojitz Group subsidiary Japan Vietnam Fertilizer Co., Ltd. (“JVF”) produces compound chemical fertilizers using steam granulation. This manufacturing process pulverizes the raw materials, creating dust particles, but JAV has introduced equipment to control the amount of dust released into the atmosphere.

Additionally, the fertilizer mixing process uses water. The water used in this process is the same water used to collect the aforementioned dust particles. In this way, JVF recycles water within the facility to create a factory with zero water discharge.

These efforts to control air pollution and use water resources effectively have helped JVF achieve sustainable operations.
