Over the years, our production processes have been continuously improved to transition towards a more regenerative and restorative model. We believe the circular economy model, where resources are reused, recycled and recovered throughout the product lifecycle, allows us to utilize resources in the most efficient and responsible manner.
Steam is essential in our brewing process, and we use a substantial amount of it. We work with our steam suppliers to provide us with a reliable source of renewable energy through improving their working processes and safety policies.
Agricultural by-products such as rice husk, sawdust, and woodchips (which will be thrown into rivers or burnt if not used) are bought from local farmers who consequently enjoy an increase in income in return. In 2017, over 52,800 tonnes of rice husk – valued at approximately VND 42.2 billion – was bought to power our operations, generating 100% thermal energy for four of our six breweries.
Our commitment to increase the use of biomass impacts our community and our environment positively. This initiative reduced our CO2 emission by around 50%, compared to using fossil fuels. Moving forward, renewable thermal energy will be used to brew beer at the remaining two breweries when their extension projects are complete.
Wastewater is another critical component of our water management cycle. The goal is to go beyond mere pollution abatement and to instead create value from wastewater for the benefits of society and the environment.
Having gone through the treatment process, the treated wastewater in our breweries can be safely returned to the environment andreused for productive purposes, such as supportingaquaticlife and vegetation. We even recover the gases that come off the waste-water treatment process to use as biogas as another form of renewable energy.
At HEINEKEN Vietnam, our Zero Waste Programme continues to inspire and support our production sites to look for innovative ways to divert waste from landfill.
The main residual waste that we generate typically include brewer's spent grains, surplus yeast and materials such as glass, cardboard, aluminium, plastic and paper.When waste is generated, we prioritize re-use, recycling (into animal feed and fertilizer) and other forms of recovery (such as energy recovery) to minimize disposal via landfill.
In 2017, 99.01% of our inputs were re-used or recycled, with only approximately 1% lost or sent to landfill - diverting more than 235,473 tonnes of waste.
