Reduction of Environmentally Hazardous Substances

The Group strives to protect the Earth's finite natural resources by reducing waste and using resources efficiently. We also enforce appropriate management for chemical substances and strive to minimize environmental impact by reducing chemical waste.

Waste Reduction

We promote zero emissions initiatives based on a reduce, reuse, and recycle (3Rs) approach.

FYE March 2017 - Meiji Co., Ltd. Group company Nihon Kanzume, Co., Ltd. was unable to conduct production of its mainstay canned corn product due to the impact of flooding damage caused by Typhoon Lionrock. The significant reduction in industrial waste was due to this.

Appropriate Chemical Substance Management

We strive to reduce chemical emissions. Measures include equipment to absorb vaporized chemicals, switching to safer substances, and improved manufacturing methods that reduce or eliminate chemical substances.

PRTR Substances

We report chemical emissions and transfers in accordance with Japan's Pollutant Release and Transfer Register (PRTR) Act. Reporting is carried out at nine plants for Meiji Co., Ltd., and three plants and two research centers for Meiji Seika Pharma Co., Ltd.

At Meiji Seika Pharma, each pharmaceuticals plant and research center has a chemicals management committee that sets standards for handling chemical substances. The company manages procurement and inventory volumes, checks emission and transfer volumes, and strives to reduce emissions.

PCB Management

Each of our operating bases engages in appropriate management of transformers and capacitors containing polychlorinated biphenyls (PCBs).

Appropriate management of fluorocarbons

As an alternative fluorocarbon to specified fluorocarbons (R22, etc.) widely used in air conditioners, large-scale facilities are progressing with the switch to natural refrigerants, such as ammonia.

Discharged water

The Meiji Group has established in-house standards for discharged water that are more stringent than those required by law.
We are working to prevent water pollution.
To reduce the impact of water pollution on the environment, at plants and processes producing large volumes of discharged water we are installing discharged water treatment facilities that utilize the activated sludge process*1 to limit discharged water load when releasing water into rivers or sewers.
In addition to the use of the activated sludge process, at companies such as the Meiji Co., Ltd. Sakado Plant and at Meiji Chewing Gum Co., Ltd., we are incorporating discharged water treatment technology that utilizes methane fermentation*2.
We use methane gas as a fuel for boilers. At Meiji Seika Pharma Co., Ltd., water is released after confirming that discharged water generated in production processes and rainwater conform to legally mandated levels. We also have constructed a primary reservoir pool for emergency use in the event of a problem with rainwater discharge to prevent the water from being released outside the facility in order to preserve the river environment. We are reducing the water resource input volume and the water discharge volume by reusing the coolant water in our factories.

*1: Activated sludge process - Treatment process that uses organic sludge (activated sludge) containing aerobic microorganisms (they prefer air) to clean dirty water and discharge water.
*2: Methane fermentation treatment method - Treatment method that uses anaerobic microorganisms (they dislike air) to break down organic solids in discharged water and convert them to methane gas and CO2.
