Sadia Javed

Profile

I am currently a researcher at University of Leeds working on waste valorisation through food-safe yeast, transforming underused food and agricultural side-streams into sustainable, high-value ingredients and products. My work focuses on applying fermentation and biotechnology to convert waste streams into safe proteins, bioactive compounds, and circular economy solutions that support food security and reduce environmental impact. At Leeds, I contribute to innovative research in sustainable food systems, alternative proteins, and microbial bioprocessing aimed at creating scalable technologies for a more resilient future.

Research interests

My research focuses on sustainable food biotechnology and circular bioeconomy approaches that convert underutilised food and agricultural side-streams into safe, high-value ingredients using food-grade yeast fermentation. I am particularly interested in waste valorization strategies that transform nutrient-rich waste streams into alternative proteins, bioactive compounds, and functional food ingredients that can contribute to food security and reduce environmental impact. Recent work at University of Leeds highlights how fermentation can upcycle agri-food waste into sustainable microbial protein for use in foods and meat or dairy alternatives.

A key area of my research is optimisation of fermentation systems for variable waste feedstocks. Food side-streams are often complex and inconsistent, so improving process design, strain performance, and downstream recovery is essential for scalable production. I am interested in combining biotechnology with data-driven tools such as artificial intelligence to improve yield, consistency, and commercial viability of yeast-based bioprocesses.

Beyond process innovation, my research considers food safety, regulatory acceptance, and real-world adoption of upcycled foods. Successful waste valorization depends not only on scientific advances, but also on consumer trust, policy frameworks, and economically viable supply chains.
