.AB Mauri’s yeast site in Sorocaba, BrazilAB Mauri’s business in Brazil has reduced its waste to landfill through several initiatives that aim to repurpose waste streams into value-added new products.
At its site in Sorocaba, which focuses on egg-based products for its Sohovos brand, AB Mauri has developed processes to repurpose both of its main types of waste, empty eggshells and wastewater treatment sludge. The empty eggshells are cleaned, dried and crushed at the site into a new powder, which is used as fertiliser by different partners.
To dispose of the viscous mix of water and waste solids, the Sorocaba site has been working with a partner in January 2024 who incorporates it as an ingredient in organic fertiliser products, replacing the previous practice of paying a contractor to transport and dispose of it through landfill. The two initiatives have helped the site drive down its landfill waste to zero.
Elsewhere in Brazil, waste previously sent to landfill has been repurposed for use in biomass boilers to create low-carbon energy for manufacturing operations, with residual waste sent to asphalt manufacturers. These initiatives form part of a programme that has enabled an overall reduction in waste to landfill in Brazil from over 40% in 2019/20 to just below 7% in 2023/24.
