Bespak® has collaborated with Tunley Environmental to perform a product carbon footprint assessment of the Bespak® valve, using life cycle analysis.
Bespak Case Study
Bespak®, a world-leading provider of orally inhaled and nasal drug products, has been developing and supplying innovative devices for decades. As part of their commitment to sustainability, Bespak sought to gain a deeper understanding of the environmental footprint of their products. They needed robust, credible data to identify key “hot spots” across product lifecycles and to guide impactful carbon reduction strategies.
Dr Aaron Yeardley from Tunley Environmental® conducted a comprehensive product carbon assessment, following ISO 14067 standards and LCA methodologies aligned with ISO 14040/14044. This process involved collaborating closely with Bespak to gather detailed bills of materials, researching existing product data, and integrating the findings into Bespak’s product design process, ensuring sustainability considerations from concept through to legacy products.
Through these assessments, Bespak gained actionable, science-based guidance on decarbonisation. Valve manufacturing has already transitioned to renewable electricity tariffs, avoiding more than 1,500 tonnes of CO₂e emissions each year. In parallel, Bespak is actively working with suppliers to switch to higher-recycled-content aluminium, an identified opportunity that will reduce embodied carbon by up to 4,000 tonnes CO₂e annually once fully implemented. These efforts have enabled full carbon footprint mapping of key valve products, benchmarking of alternative materials and designs, and creation of a clear, prioritised roadmap for ongoing reductions.
Reflecting on the collaboration, Shaun Williams, Product Engineering Manager at Bespak, said, “The Tunley Environmental team has been fantastic – very professional, approachable, and highly knowledgeable. They guided us through the process, challenged our thinking, and provided practical recommendations that we can implement straight away. We would absolutely recommend them to other organisations looking to take a step forward in sustainability.”
We would like to thank Bespak for choosing Tunley Environmental as their sustainability partner and we look forward to any future projects we work on together to improve and develop their sustainability efforts.
