Championing carbon-neutrality through flagship projects in vietnam

Da Nang Brewery: Leading in water efficiency

Da Nang brewery’s water efficiency has improved 44.6% compared to 2010 and has been among the Top 5 most water-efficient breweries across HEINEKEN worldwide since 2014. The brewery is also exploring possibilities on water circularity that allows HEINEKEN’s grade A wastewater to be reused by other companies in the same industry compound.

Hoc Mon Brewery: Pioneering innovative carbon reduction solutions

Since it first started operations in 1993, Hoc Mon brewery has grown to become one of the most modern and sustainable breweries in Asia.

First to pilot selling liquid CO2 in 2019 - CO2 that is naturally produced during the fermentation process is recovered, turned into liquid CO2 and used for our beer processes. This ensures that we have enough liquid CO2 for our production processes and enables us to sell it for other industrial usage with a total volume of 2,796 tons in two years. This has since been rolled out to other breweries.

Identified as “Lighthouse brewery” within HEINEKEN (1 of 4 globally) for implementation of the Connected Brewery programme – Harnessing digital technologies to monitor performance and track deviations in real-time when bottling lines are running, tackle production issues as well as track utilities consumption and material use effectiveness

Circularity at HEINEKEN Vietnam

Thermal energy at our breweries is generated from burning agricultural waste, or biomass, such as woodchips and rice husks, generating income for farmers. 5 out of 6 of our breweries are now brewing 100% by biomass with plans for the sixth brewery already underway and operational in 2022.

We have invested heavily in world-class wastewater treatment systems at all our breweries and have raised wastewater treatment to the highest level of A class, surpassing the government’s requirement and safe enough to sustain aquatic life – we even have our own fishpond in our Hoc Mon brewery to show this.

By-products (spent grain and sludge) from waste water treatment) are sold to third-party suppliers who transform them into bricks or use them as animal feed or compost for crops.

In total 99.7% of our waste is reused/recycled.

Route-to-market process designed so that our bottles are returned for to be reused on average 20 times. After, they will be sent to a glass factory to be recycled.

Ho Chi Minh Brewery: Pilots liquid carbon dioxide (CO2) recovery from fermentation process

Usually, liquid CO2 (CO2 gas that is highly compressed and cooled into a liquid form) is obtained by burning fossil fuel. By optimizing the CO2 recovery process during fermentation, CO2 can be recovered and turned into liquid CO2 which is then reused onsite or sold for other industrial use. The recovered CO2 helps reduce HEINEKEN’s emissions from the fermentation process, while also enabling other companies to avoid emissions caused from the liquid CO2 production process. Liquid CO2 is used widely in various industries. Examples of various uses are in the production of life jackets, in the entertainment industry to achieve special effects such as fogs and hazes or for refrigeration, preservation, storage and softening in the food industry. Since October 2019, 866,000 kg of CO2 has been recovered (equivalent to the emission from burning of approximately 323,000 litter of diesel) generating 110,000 EUR revenue within 5 months at one of our breweries.
