Environmental Information

1. Environmental Installations

Introduction of Environmentally-aware Installations

The Tsukiji factory was designed to be a state-of-the-art base of production. The wide amount of space available was utilized towards new installations such as rooftop greening, solar power generators, and LED lighting.

Solar Power System

480 monocrystalline solar panels, generating a maximum of 100kW, have been installed on the roof as part of proactive efforts to increase green, renewable sources of energy.

Rooftop Greening

2000㎡ of rooftop space have been covered with Mexican stonecrop, which helps reduce the temperature inside the factory during summertime. This reduces electricity consumption and creates a pleasant working environment.

Expansion of Solar Panels at Tsukiji Factory
Originally, 480 monocrystalline solar panels were installed to reduce CO2 emissions and shift towards green renewable energy sources. In February 2022, work began to utilize more factory space and increase this by 1,936 panels that altogether will generate a maximum of 836kW. Yearly output will reach around 818MWh, covert 10.8% of the factory’s energy consumption to renewable sources, and reduce CO2 emissions by around 355 tons per year. Future endeavors to further expand renewable energy and aid the environment are always underway.

2. CO2 Emissions

Our CO2 Emissions Record

CO2 reductions efforts and energy efficiency begin with an understanding of our current CO2 emissions. With 2013 levels as a benchmark, we set medium-term objectives for CO2 reduction.

CO2-Free electricity introduced at our Shizuoka Headquarters in Japan

We have introduced "Shizuoka Green Electricity" effective October 1, 2023.
As a result, all electricity used at our Headquarters will be 100% renewable energy, and CO2 emissions associated with electricity use will be virtually zero.

3. Waste Disposal

Waste management regulations have been set to guide management and reduction of waste activities to ensure any waste products discharged in the course of operations are properly handled in accordance with Waste Management Law.
  1. Amount of Waste Generated
    703 t/year *2022 91.9% YoY (8.1% decrease)
  2. Discharge of Valuable Resources
    1724 t/year *2022 99.0% YoY (1.0% decrease)
  3. Landfill Disposal
    0 t/year 100% resource circulation

Waste Generated Yearly Trend

2013-2015 reduction
2016-2017 large increase
2018-2019 increase
2019-2020 large reduction
2021 increase
2022 large reduction

4. Regional Activities

A key policy of Murakami Corporation is “Regional Coexistence,” which drives efforts to benefit local environments. Every factory serves as a base for public beautification efforts.

Regional Coexistence  Public Beautification


Community Outreach  Flower Planters

Community outreach includes the distribution of flower planters as part of our corporate role to serve as a beneficial presence in society. Planters are replaced three times a year with seasonal blossoms.

5. Waste Reduction

Reduction of Paint and Thinner Waste

Painting Process
Adoption of Solvent Recovery Apparatus for Thinner Recycling
Liquid paint waste (paint waste, thinner waste) is distilled in-house and recycled as cleaning thinner
  • Solvent Recovery Apparatus

90% of thinner is recoverable from paint waste, which also reduces purchases of cleaning thinner


Reduction of Plastic Waste

Molding Process

Plastic waste (runner, checkpoints, defective product) is ground up and recycled.

  1. Raw (virgin) and recycled (resin pellets) materials are injected into tanks or automatically collected in the ground material (runner mill) tank.
  2. Virgin, recycled and ground material are sent from the raw materials tank to the measuring apparatus.
  3. Raw materials are mixed in the measuring apparatus and sent to the dryer.
  4. The dryer serves as a centralized supply for the molding apparatus.
  5. Throwaway product made during setting, intermittent die maintenance, or momentary stops is recovered by the operator for recycling.
  6. Recovered plastic waste is ground in the industrial product mill and automatically recycled.
  7. This material is not sent out for disposal.

Reduction of Glass Waste

Mirror Process
Development of glass waste recycling business:Foam glass manufacturing, commodification
Creation of Products from Glass Waste

A great benefit to the environment

Recycled glass foam glass
Function Deodorizer, water purification, weed control, etc.
  • Placed underneath solar panels to prevent weed growth
  • Used as material for deodorizers
  • Many other potential business applications

6. Environmental Product Development

Heated Washer

  • Front window frost removal is often a time-intensive process with only temporary results. A heated washer solves this issue in a safe and easy way, greatly reducing worktime involved.
  • A user-friendly tool that helps reduce use of heaters in removal of window frost, which in turn saves energy and reduces CO2 emissions.
Product Specifications
The product stores heated washer fluid from that day’s usage in a vacuum-sealed container, so it is pre-heated and ready to go the next morning. Liquid used during operation is replenished from a washer tank, heated and stored at temperature. The vacuum-sealed container minimizing the escape of heat and helps reduce energy consumption.
