A new sustainable project is working to turn dairy processing waste into valuable products such as biofuels, renewable chemicals, and sustainable foods. This effort aims to support a circular food and energy system while reducing environmental harm.
Dairy processing side-streams (DPS), like the liquid waste left after making yogurt, butter, and ice cream, are rich in nutrients. However, these waste products are often thrown away due to food safety concerns. Millions of tons are discarded each year, leading to resource loss and added greenhouse gas emissions.
This project plans to change that by using advanced biomanufacturing. The team will explore how to use biocatalysis and cellular agriculture to make use of DPS. They aim to turn dairy fats into renewable biofuels and convert proteins and carbohydrates from the waste into new types of food.
The project’s focus is not only on creating new products but also on protecting the environment. These methods offer clean, carbon-neutral alternatives to traditional fuels and food sources. At the same time, they help reduce harmful waste.
To check the success of this idea, a techno-economic analysis (TEA) will be done. This will help researchers find the most promising and cost-effective ways to use dairy waste.
The work brings together experts in food science, engineering, and sustainability. Their goal is to develop new technologies that lower carbon emissions and increase the strength of our food and energy systems. This research aligns with national goals to fight climate change and build cleaner energy systems.
In short, the project is a smart and sustainable way to turn dairy waste into something valuable—making our future greener and more efficient.
