At Asahi Breweries, we’re pouring effort into the development of new, environmentally-friendly ways of brewing by developing technology to reduce CO2 emissions during manufacturing, by purchasing green power, and by introducing solar energy generation facilities.
In 1990, it took 9.1 bottles of water to produce 1 bottle of SUPER DRY. Brewing called for a lot of water, plain and simple. We scoured factories all over Japan for ideas on ways to use water more efficiently. In eighteen years, we’ve managed to cut back by 36%.
At the Hakata factory, we’ve installed rooftop solar panels which now provide some of the energy used by the entire factory. We display the amount of power currently being generated in the visitors’ walkway; if you’re interested, by all means take a look. Beer isn’t the only thing you can make at a brewery. Bottle by Bottle, we’re creating a brighter future for the Earth and for humankind.
There’s even innovation in wastewater purification. By using biotreatment, we extract methane gas from the wastewater and create steam to heat the kettles. We hold fast to our resolution not to waste resources, all the way to the end of the line.
Alcohol and carbon dioxide are produced by the hearty work of live yeast. We do not waste that extra carbon dioxide. Instead, in order to produce SUPER DRY’s crisp taste, we use it one more time, after filtration. The CO2 generated in our factories is used without waste.
We don’t waste the dregs from the brewing ingredients either. Malt feed is very nutritious; and adding honey to it, we can recycle it as cow fodder. Since it’s made from natural ingredients, it can be fed to cows without worry, and it’s getting very good responses from livestock breeders all over the country.
All of our factories transform 100% of their garbage into reusable resources. Bottle caps are reformed into steel and used as building materials, and the garbage produced by the factory cafeterias is completely broken down by processors into an incredible twenty categories. We run zero-waste factories, where no resource is discarded.
At the Kanagawa factory, 12%* of all power used annually is purchased electricity, produced by wind power. By using natural energy, we strive to bring you high-quality beer as economically as possible. We’re rising to the challenge of developing factories that are cutting-edge.

CFCs are greenhouse gases which are destroying the Earth’s environment. Early on, Asahi Breweries became one of the first to research how efficient a natural refrigerant could be made. The Nagoya and Kanagawa factories are being transformed to completely non-CFC. Our vending machines at truck stops and the refrigerators in our cafeterias are specially ordered machines that use absolutely no CFCs.
