On June 5, 2025, coinciding with World Environment Day, South Australian winemaker Nepenthe Wines launched a packaging overhaul featuring fully removable aluminum capsules developed with Interpack. The CAPR closure system allows easy separation of aluminum from glass bottles, addressing a recycling bottleneck where attached capsules cause 20-30% of wine bottles to be rejected at sorting facilities, per Australian Recycling Council. Combined with lighter glass bottles and 100% recycled-content labels, the initiative under Nepenthe’s “Naked in the Vines” campaign aims to boost recycling rates and cut emissions. With Australia producing 1.2 billion wine bottles annually, can Nepenthe’s redesign reshape industry standards, or will consumer behavior and supply limits hinder impact?

Packaging Redesign Details

• CAPR Closure System: A tearaway aluminum capsule enables consumers to separate materials, increasing recycling rates by 15-20%, per Interpack trials.

• Lightweight Glass: Altitude and Elevation ranges use 10% lighter bottles, reducing transport emissions by 5% (1,000 t CO2e/year), per Nepenthe’s 2023 life cycle analysis.

• Recycled Materials: 100% recycled-content labels across all lines; APEX bottles test 70-90% recycled glass, limited by local supply.

• Consumer Engagement: Removal instructions on capsules and digital campaigns promote recycling, targeting 50% consumer compliance, per Nepenthe.

• Testing: A three-month trial confirmed no impact on wine quality or storage stability.

“This system makes recycling practical,” said Nepenthe’s sustainability lead.

Interpack’s CEO added, “CAPR balances cost and sustainability.”

Strategic Context

Aligns with global sustainability trends:

• Swiss Glacier Collapse: 1.5°C warming underscores need for low-carbon packaging.

• STOXX ICE Indices: Sustainable investment supports circular economy initiatives.

• Illinois HJR 27: Sustainable procurement parallels Nepenthe’s supply chain focus.

• Antibiotic Pollution: Reducing waste aligns with cleaner environmental systems.

Challenges and Risks

• Consumer Behavior: Only 40% of Australians recycle wine bottles correctly, per Planet Ark, risking 10% rejection rates even with CAPR.

• Supply Constraints: Recycled glass availability caps at 70-90%, with $50M needed to scale local facilities, per Glass Packaging Institute.

• Cost Pressures: CAPR adds 5% to packaging costs ($0.10/bottle), potentially impacting margins, per Nepenthe.

• Policy Risks: U.S. deregulation, like $1.5B Army Corps cuts, may weaken global recycling incentives, affecting 5% of export markets.

What’s Next?

Nepenthe aims to roll out CAPR across its 500,000-bottle portfolio by 2026, targeting a 20% recycling rate increase. A $1M partnership with Interpack will explore recycled plastic alternatives by 2027. Australia’s wine industry could adopt similar systems, saving 100,000 t of waste annually, per Wine Australia. Global sustainable packaging markets may hit $500B by 2030.

“This redefines wine sustainability,” said Nepenthe.

With 36 Gt CO2e emitted globally in 2024, Nepenthe’s overhaul could cut 0.01 Gt by 2030. Will it drive industry change, or face adoption barriers?
