Preventing Global Warming

Initiatives in Production

Reducing CO2 through Energy-saving and Use of Renewable Energy

We are committed to energy efficiency at Suntory Group plants through production activities harmonized with the environment. Making records of and managing the operational status centrally is useful for employing energy efficient activities in the production process. Furthermore, we are working to combat global warming from a variety of angles, including by switching to low CO2 emitting fuels and by using renewable energy.
Activities being carried out at plants are shared at regularly-held engineer meetings to expand horizontally.

Reductions Made by Introducing Cogeneration Systems

We are utilizing cogeneration system (combined heat and power) in our production activities. This system recovers heat generated from in-house generation and uses it as part of a heat source for preparing beer and extraction of coffee and tea, which increases energy efficiency to 70-80% and reduce CO2 emissions by 20-30%. As of April 2019, the system is introduced at three plants in Japan. These are the Haruna Plant of Suntory Products Ltd, and the "Natural Water Beer Plant" Tonegawa Brewery in Gunma Prefecture and Kyoto Brewery of Suntory Beer Ltd.

Switching to Fuels Low in CO2 Emissions

Most factories have completed the conversion from using heavy oil to city gas and LNG (liquefied natural gas). These gas fuels have fewer CO2 emissions per unit of heat and they contain almost no sulfur.

Energy-saving Activities in Accordance with Increase in Production Capability - Suntory Beer Ltd.

Tonegawa Brewery of Suntory Beer Ltd. has undergone a construction to increase its production capability of beer in 2013. At the same time, latest cauldron was introduced in the preparation stage for efficient use of energy, along with renewing boilers and cooling facility to optimize the energy supply facility. As a result, the energy efficiency improved by about 20% in the plant.

Energy-saving Activities at Overseas Production Sites

We are promoting energy-saving activities based on our know-how and technology in Japan even at overseas plants of the Suntory Group.

Energy-saving Activities at a Tequila Plant in Mexico

We have introduced energy-saving activities to the Sauza Plant in Mexico, which uses a lot of fuel, based on our knowledge and technology in Japan. We have been conducting initiatives to improve the heat recovery rate at distilleries since 2016 and installed a new type of once-through boiler in 2017. Furthermore, these activities have also adopted the 2016 Joint Crediting Mechanism Financial Support Business that contributes to reducing greenhouse gas emissions in developing countries.

Promoting the Use of Renewable Energy

We have been increasing the use of various kinds of renewable energy at our plants, including the use of solar power, snow ice, biomass and micro-hydro power.

Use of Photovoltaic Energy

The Minami Alps Hakushu Water Plant of Suntory Products Ltd. is installed with the largest photovoltaic panels in the beverages industry, capable of generating approximately 490kW of electricity. They provide some of the plant’s power, and make it possible for us to reduce our CO2 emissions by approximately 205 tons per year compared to when we buy electricity from a power company.
In addition, The Minami Alps Hakushu Water Plant and Hakushu Distillery introduced lithium-ion battery equipped electric buses for the first time in private company for factory visits in 2011, using electricity generated from photovoltaic power generation at the Hakushu Plant.
Solar power generation equipment has been installed on some of the roofs and premises by Solar Frontier K.K. and the Development Bank of Japan, Inc. at the Suntory Products Ltd. Haruna Plant and Suntory Beer's Kumamoto Aso Brewery. The two plants generate a combined output of approximately 3.2 MW, which is an equivalent to the yearly power for roughly 660 households. This is estimated to have a CO2 reduction effect of approximately 1,900 tons.

  • Largest scale photovoltaic panels in the beverage industry

  • New lithium-ion battery equipped electric buses

Use of Snow and Ice Thermal Energy

For the use of snow and ice thermal energy, Iwanohara Vineyard Co., Ltd. takes benefit being located in region of heavy snowfall and installed snow room in 1898 to store snow during winter. The thermal energy of snow is used to control the temperature for fermenting wine and storage, using natural energy in winemaking. Following the tradition, snow room was rebuilt in 2005 and is being used to cool wine-aging warehouse.
In Okudaisen Bunanomori Water Plant of Suntory Products Ltd., which also is located in region of heavy snowfall, also implements snow room and used as part of thermal control during spring.

Use of Cold Groundwater

We are effectively using cold groundwater that stays at an almost constant temperature (low temperature) throughout the year to cool manufacturing equipment and in other processes at the Hakushu Water Plant of Suntory Products Ltd. In addition, hot and cold water such as effectively recycling heat produced in air compressors and boilers to heat groundwater to prevent condensation when filling plastic bottles with low temperature groundwater.

Promoting the Use of Energy from Biomass

SUNTORY CHITA DISTILLERY LIMITED. has been using residue liquid from distilling and corn residue when making grain whisky as fuel for generating steam needed to heat when distilling since 1997. Approximately 6,000 tons of CO2 can be reduced by reducing liquefied natural gas (LNG) usage with the use of biomass resources. This is the equivalent of roughly 40% of fuel used at SUNTORY CHITA DISTILLERY LIMITED.
