In pursuing net zero emissions, the metal packaging industry acknowledges that success requires an all-encompassing commitment to collaboration and sustainability throughout the value chain.
FREMONT, CA: The journey toward achieving net zero emissions is a formidable challenge for various sectors, including metal packaging manufacturers. Mitigate the impact of climate change by balancing emissions released into the atmosphere with emissions removed. For the metal packaging industry, this entails unique steps within its value chain, emphasizing changes in energy consumption and advancements in the Circular Economy to sustain materials in continuous life cycles. This approach allows for creating essential goods while minimizing resource consumption and conserving energy during production, ultimately reducing the environmental footprint.
Sustainable metal packaging manufacturing involves a holistic approach considering raw material selection, energy efficiency, waste reduction, recycling infrastructure, circular economy principles, consumer education, regulatory compliance, innovation, life cycle assessments, and collaboration. Metal packaging manufacturers can achieve a sustainable and eco-friendly future by embracing sustainability. Transitioning to renewable energy sources and reducing overall energy consumption are part of the ongoing efforts to achieve these goals. While some heating processes still rely on gas, a shift toward electrification and exploration of innovative solutions is underway to decrease global emissions.

Emissions present a distinct challenge and represent the sector's largest gaps in progress. These emissions result indirectly from activities across the entire value chain and constitute a substantial portion of the overall footprint due to the industry's extensive interactions with upstream and downstream stakeholders. Addressing emissions requires industry-wide collaboration, with all value chain participants aligning on shared goals and action plans. For metal packaging manufacturers, this often revolves around fostering circular material flows. Preserving used beverage cans from ending up in landfills and ensuring their successful recycling contribute to an increased supply of recycled materials for new can production. Beyond the environmental benefits, such as reducing the reliance on finite raw materials, maintaining this circular loop reduces energy consumption. Manufacturing cans from recycled materials saves more than 90 percent of the energy required instead of using virgin substrates, reducing emissions and progressing toward net zero.
The challenge in managing emissions lies in the need for collective effort. All stakeholders along the value chain must collaborate actively, transcending silos to effect meaningful change. This entails focusing on procurement processes and engaging suppliers to source materials for packaging manufacturers sustainably. Collaborating with suppliers to enhance recycled content in their materials and promote eco-friendly production methods is crucial.
Downstream partnerships are equally vital, involving effective consumer education to encourage proper recycling habits and improved material recovery strategies. While aluminum cans already represent the most recycled beverage package globally, there is room for improvement. Often, valuable materials are misrouted and lost from the Circular Economy due to information gaps or infrastructure challenges. Closing these gaps necessitates upstream and downstream alignment and cooperation with environmental organizations to define each stakeholder's responsibilities in enhancing education, investing in recycling systems, and monitoring progress collectively.
