Environmental Performance

Product Life Cycle and Inventory Flows

The Morinaga Milk Group strives to reduce its environmental impact by setting voluntary standards that are stricter than the legal and regulatory standards. Our environmental conservation activities include, but are not limited to, the following: promoting energy conservation and environmental technology development to support the shift to a low-carbon economy; practicing responsible procurement to help realize a recycling-oriented society; low-cost production operations; and reducing waste by practicing the 3Rs (Reduce, Reuse, Recycle).

Fiscal 2012 input and output figures for each stage in the life cycle of our products are shown in the flowchart below.

FY2012 Life Cycle and Inventory Flows

Energy Use and CO2 Emissions Reduction

The Morinaga Milk Group also strives to minimize energy use and CO2 emissions from production processes.

In FY2012, energy use increased 1.4% as a result of a 1.6% increase in production volume. While CO2 emissions increased partly as a result of an increase in the values of emission factors for purchased electricity, ongoing energy conservation efforts at our production plants led to a 0.2% decrease in energy intensity (energy use per unit of output) from the previous year.

Energy Conservation

Morinaga Milk production plants have introduced a variety of systems to increase the efficiency of their fuel and electricity use, including cogeneration systems, high-efficiency once-through boilers, high-efficiency centrifugal chillers, and cold storage systems that use electricity at night. They are also in the process of switching to LEDs and other energy-efficient lighting technologies.
To move forward in shifting away from fossil fuels such as oil, coal, and natural gas and toward renewable energy sources, our plants operate equipment that use solar photovoltaic and biomass thermal energy, and also purchase electricity generated from renewable sources.

Concept of Cogeneration

Water Conservation

Some of the greatest challenges for the Morinaga Milk Group as a food product manufacturer are to secure an abundant supply of high-quality water, to use that water efficiently, and to return it to nature in a clean state.

In addition to the water in our products, some 60% of our total water is for cleaning equipment used during and after manufacturing processes. To reduce water use in these applications, we have introduced water pinch technology?a water application of pinch technology?with which we strive for water reuse, recycling, and efficient use. Additionally, by equipping all of our production sites with comprehensive wastewater treatment facilities, we return the water to nature in a way that has a small environmental impact.

*Water pinch technology: A method for maximizing water efficiency throughout a factory by analyzing the quantity and quality of water used and released by each process for reuse and recycling.

Zero Waste to Landfill

Morinaga Milk promotes the reuse and recycling of industrial waste with the goal of virtually eliminating waste sent to landfills. Each of our production plants sets and works toward annual targets as part of its ISO 14001 activities.

With food waste and sludge accounting for almost 80% of all waste, our plants strive to limit the generation of these waste streams while also reusing and recycling these materials as much as possible, such as by converting them into feedstock and fertilizer.

*Zero waste to landfill Morinaga Milk defines "zero waste to landfill" as maintaining a material recycling rate of 99.0% for at least three years.


The Morinaga Milk Group has published its own Eco-Friendly Packaging Guide. This guide has been effective in helping us, from the product design and development stage, to develop containers and packaging to consider 3Rs (Reduce, Reuse, Recycle), safety, and easy use, and to reduce environmental impact by making packaging lighter and by adopting alternative materials such as bioplastics.

As a member of industry groups related to container and packaging recycling (Plastic Packaging Recycling Council, Paper Packaging Recycling Council), we also work actively to promote the 3Rs and raise environmental awareness among our customers.
