Preventing Global Warming

Energy Conservation in Vending Machines

Energy Conservation in Vending Machines

We are implementing various initiatives to save energy in vending machines in Japan as one of priority initiatives to reduce Green House Gas(GHG) in the entire value chain.

Key Features of Suntory Vending Machines

Reducing Energy Consumption of Vending Machines

Since we introduced a peak-cut feature in 1995, we have been striving to introduce vending machines with lower consumption of electricity. Since 2007, we have been promoting installation of heat-pump vending machines that facilitate even more efficient energy usage compared to conventional vending machines as main energy-saving machine. Nearly all of the vending machines put into use in 2010 and all new vending machine (excluding some special-function machines) from 2011 were heat-pump models and also LED lighting were installed to them.
From 2012, we started introducing Hybrid Heat-pump Vending Machines which can reduce electricity consumption by additional 30% compared to normal Heat-pump Vending Machines.
In addition, by fitting refurbished machines*1 with heat-pump equipment, the ratio of heat-pump vending machines against all Suntory vending machines was 87% in the end of 2021
In 2013, "Mahou VIN Vending Machines"*2 which has a capability of suspending cooling for extended time by to having high refrigerant effect from using vacuum heat insulation materials, etc., in addition to energy saving heat-pump function. This vending machine enables the reduction of both environmental impact and electricity load during the peak hours in summer.

What is a heat-pump vending machine?

A heat-pump vending machine in Japan is a vending machine with a built in system to collect heat generated by the cooling chamber for the heating chamber. These vending machines largely contribute to energy saving through function to effectively use heat inside the vending machine and latest machine can even exchange heat with the atmosphere.

Introducing Ultra-Energy-Saving Vending Machines

In April 2014, we began adopting "Ultra-Energy-Saving Vending Machines" (Eco Active Machines) that operate on approximately half the energy consumption (420kWh/year) compared to conventional heat-pump vending machines with the cooperation of machinery manufacturers the use of to further aim to contribute to reducing environmental impact. It stores two compressors, one dedicated to heating and other cooling and uses various latest technologies such as inverter control, vacuum heat insulation materials, electronic expansion valve and LED lighting to control energy consumption to an optimum condition to realize reducing electricity consumption.

Promoting a 24-hour Lights Out

To promote reductions in GHG emission and combat global warming, vending machine manufacturers have promoted energy-saving measures since 1991, prior to establishment of the Kyoto Protocol. As a result, during the 15 years leading up to 2005, we achieved an approximate 50% reduction in energy consumption per vending machine. The industry also agreed to aim for a further 37% reduction by 2012, in comparison to 2005 figures, with indoor vending machines having a 24-hour "Lights Out" rule and outdoor machines having no lighting during daytime hours*. The industry met its goal in 2011.

    Reduces about 10% of power usage by turning off the lights during the day time, about 20% by 24 hours

Measures Against Chlorofluorocarbon

Controlled chlorofluorocarbons that destroy the ozone layer are not used for refrigerants in our vending machines today. New vending machines that are introduced also use no chlorofluorocarbons substitutes that have a large impact on global warming. All of our machines are assumed to be R-1234yf, which has a low global warming potential.

Initiatives to Reuse Vending Machine Parts

We are actively conducting initiatives to realize effective use of resources even in vending machines. We are advancing development of technology toward the reuse of parts as well as management systems for the reuse of parts in order to use vending machine parts that are collected in vending machines again. In 2021, the reuse rate of parts that required repair or maintenance was 58%. We are striving to effectively use resources by expanding the components to reuse parts even further in the future.

Ensuring Reasonable Waste Disposal of Vending Machines

We are leading the industry in building a Vending Machine Waste Disposal System that collects and recycles vending machines to throw away, which we have expanded nationally since January 1997. We are strictly managing disposal from the initial selection of vending machines to discard to the final disposal in compliance with the revisions to the Wastes Disposal and Public Cleansing Act in April 2001. We are properly processing broken machines by understanding the amount of machines to collect based on the Act for Rationalized Use and Proper Management of Fluorocarbons even in regards to the fluorocarbons that are used as a refrigerant in vending machines.

Installation of Vending Machines to Provide Beverages in Emergencies

We are developing and advancing the installation of vending machines to provide beverages in emergencies to contribute to building cities able to combat disasters. Normally, it sells beverages just like a regular vending machine, but in the event of a disaster or other emergency, it provides beverages free of charge. Beverages can be easily accessed even if the power goes out. Many people used this system after the Great East Japan Earthquake that struck in March of 2011. We are progressing with the installation of these vending machines centered upon public institutions, hospitals, and companies with roughly 25,000 units put in place through the end of 2021 by implementing wire type vending machines that have the benefit of not requiring maintenance in addition to battery-type vending machines. In Japan, we plan to actively introduce these types of vending machines in the future.
