Peter Wachenschwanz, Senior Director, Integrated Supply Chain at Carlsberg Vietnam shares how Carlsberg Vietnam is translating its Brewing Tomorrow ambitions into practical action across production, resource efficiency and circularity.

As Vietnam advances towards net zero by 2050, industrial growth must increasingly be supported by more efficient resource use, lower-carbon energy and circular production models. At the Green Industries Summit 2026, Carlsberg Vietnam shared how it is integrating these principles into brewery operations and the wider conditions needed to scale progress across industry.

Organized by the Nordic Chamber of Commerce in Vietnam (NordCham) and the Vietnam Chamber of Commerce and Industry (VCCI), the summit took place in Ho Chi Minh City on 10 September under the theme “Powering Vietnam’s Green Industry 4.0”. It brought together more than 200 business leaders, policymakers and Nordic experts to explore the green and digital transitions shaping Vietnam’s growth agenda.

Representing Carlsberg Vietnam, Peter Wachenschwanz, Senior Director, Integrated Supply Chain, delivered the keynote “Brewing Tomorrow: Innovations Shaping the Future of Green Industries” and joined the panel “Building Vietnam’s Green Energy Ecosystem”. Across both sessions, he shared how the company is increasing production capacity while reducing the resource intensity of its operations.

“Green transformation begins inside the brewery, with the discipline to use less water, less energy and fewer materials for every unit we produce. But its next stage extends beyond the brewery gate. Scaling renewable energy and circular solutions requires clear policy, viable commercial models and closer collaboration across the ecosystem. The opportunity is to connect operational efficiency with system-level change, so that industrial growth can create more value with a lower environmental footprint,” Peter said.

Translating ambition into operational progress

Carlsberg Vietnam’s sustainability journey is guided by Brewing Tomorrow, Carlsberg Group’s sustainability program built around four pillars: Cutting Carbon, Protecting Nature, Inspiring Choice and Empowering People.

The Group aims to reduce emissions from its own operations by 90% and source 100% of its electricity from new renewable assets by 2032, before achieving a net-zero value chain by 2040. In Vietnam, these ambitions are being translated into investments in production technology, energy efficiency, water stewardship and circular packaging.

Phu Bai Brewery in Hue demonstrates how sustainability can be embedded in industrial expansion. Following an approximately USD 90 million investment inaugurated in August 2025, the brewery increased its installed capacity by more than 50%, becoming Carlsberg’s largest beer production site in Asia.

Despite this expansion, its new brewing line uses approximately 20% less water and 15% less energy than its predecessor. The brewery consumes around 2.1 hectoliters of water per hectoliter of beer, placing it among Carlsberg Asia’s most water-efficient breweries. It also captures and reuses the carbon dioxide generated during fermentation.

The expansion demonstrates that growth and environmental performance need not be competing priorities. By embedding resource efficiency in investment decisions and engineering design, production capacity can increase with a lower operational footprint.

Advancing circularity and lower-carbon energy

Since early 2026, Carlsberg Vietnam has achieved Zero Waste to Landfill across its brewery operations. Its approach begins with reducing waste at source and strengthening on-site segregation. Recyclable materials are recycled, remaining waste is directed to waste-to-energy solutions, and wastewater sludge is converted into agricultural fertilizer.

Circularity also extends beyond the brewery. Carlsberg Vietnam reports a 98.5% collection and reuse rate for returnable glass bottles and uses plastic crates made from 100% recycled material. Further packaging-lightweighting initiatives are being explored to reduce material consumption while maintaining product quality and performance.

Energy efficiency remains the first step in Carlsberg Vietnam’s decarbonization pathway. Efficient brewing technology and heat recovery are combined with biomass-generated steam, while its electricity roadmap includes I-REC-backed sourcing since 2022, a rooftop solar project being implemented from Q3 2026, expected to supply up to 10% of the brewery’s electricity needs, and a pathway towards direct power purchase agreements from 2028.

Peter further explored the wider energy challenge during the panel “Building Vietnam’s Green Energy Ecosystem,” alongside representatives from REE Energy and VinEnergo. The discussion connected the perspectives of renewable energy developers, industrial users and market facilitators.

For manufacturers to make credible long-term renewable energy commitments, they need regulatory certainty, workable commercial structures, reliable grid infrastructure and transparent verification. Developers and investors, in turn, need sufficient visibility of industrial demand to plan and finance new renewable capacity. Early collaboration can help translate this demand into projects that are bankable, reliable and scalable.
