Our Ingredients businesses are committed to protecting finite resources and reducing the waste generated by their operations.

Across our Ingredients businesses, waste streams are increasingly repurposed for new uses and markets. If waste cannot be eliminated or repurposed, it is recycled wherever possible.
In 2025, waste generated within the Ingredients segment increased by 33%, largely driven by the increase in production volumes. Most of the additional waste was sent for recycling or reuse. The rate of recycling improved from 75% last year to 80% in 2025. This was as a result of the businesses undertaking a range of initiatives to manage waste, including recycling paper and plastics and repurposing waste streams for fertiliser and animal feed.
AB Mauri aims to reduce waste by continuously improving the efficiency of its operations, including through smarter production line design, and by ensuring the production of quality co-products that avoid the creation of waste.
In several locations, waste from bakery ingredient manufacturing is collected and sold as by-products, turning waste into value. A dedicated co-products technology team evaluates and develops a portfolio of technologies to better exploit these opportunities, overseen by a monthly steering group chaired by the AB Mauri Chief Executive.
One example is vinasse, a by-product of yeast production, which is used in fertilisers and high-value animal feed. Similarly, soya husks from the Royston site in the UK are sent for processing into animal feed, helping the site maintain zero waste to landfill.
Several AB Mauri businesses repurpose waste as an ingredient in organic fertiliser, while others send waste for composting, reducing reliance on nitrogen-based fertilisers that are carbon intensive to produce. A co-product-based alternative to potash, a mined potassium fertiliser, is also in development.
In addition, in six manufacturing sites, biogas captured from yeast wastewater treatment is reused on-site, replacing natural gas for heat and electricity generation.
ABFI businesses are focused on eliminating waste and promoting recycling wherever possible. Training and education play a key role in raising awareness and understanding of waste management opportunities across its business activities. Guided by the ISO 14001 certification, businesses implement tailored waste management strategies that reflect their operational needs. These strategies focus on eliminating waste at source, improving reuse and recycling, and collaborating with value chain partners to convert waste into usable materials. For example, SPI Pharma recovers biogas from non-hazardous waste through incineration that is carried out by a third-party. ABITEC has also reprocessed distillation by-products into commercial products, converting 77 tonnes of waste into saleable output.
