Heat pump-style vending machines pump up the waste heat generated when cooling products and use it for heating to warm up the products. This allows reduction in power consumption compared to conventional vending machines by
cutting down the power used by the heaters.
Kirin Beverage was the first in the industry to introduce heat pump-style vending machines in 2006, and from 2012, almost all newly installed vending machines for cans and PET bottles are of this type. As of April 2020, more than 80% of installed vending machines have been switched to this type.
The latest heat pump-style vending machines are equipped with a compressor that uses an inverter to delicately control the operation (variable speed of rotation) according to the atmospheric temperature and the temperature of the products in the machine. Further, some types offer higher energysaving performance, such as with heating functions not only by using the waste heat released by the cooling chamber as previous models did, but also by capturing the heat from outside the machine, and by improving hot and cold insulation performances with the heavy use of vacuum insulation materials. These vending machines have evolved to the point where power consumption can be reduced by about 40% compared to 2013. Installation of the new models began in 2015, and we are aiming for 70% of new machines installed in 2020 to be new models.

Conventional fluorescent lighting is being replaced with high energy-saving LED lighting to reduce power consumption and achieve energy conservation.
Trend in power consumption
Change to the best-before labelling
Kirin Brewery will change its labeling of manufacture date on cans and bottles of beer, happo-shu (low-malt beer), new genres, and non-alcoholic beer-taste beverage from the conventional “year, month and early/middle/late month” of manufacture to “year and month” for products manufactured from October 1, 2020 onwards.
This change in labeling alleviates the need for managing by periods within a month and improves the efficiency in managing in-house product storage and shipping operations as well as streamlines inventory management and store display operations of distribution companies, thereby leading to increasing efficiency in the entire supply chain.
Kirin Beverage is also working to shift to labeling the “year and month” as the best before date on soft drinks.
Switching business vehicles to hybrid cars
Kyowa Kirin is proceeding with switching business vehicles to hybrid cars. The company started serially switching from the conventional certified low emission vehicles in 2009, and by the end of 2019, all company-owned vehicles are hybrid vehicles.
By cutting back fuel used in sales activities in this way, the company is achieving reductions in CO2 emissions.
