Bioenergy and Bioproducts Research Lab (BBRL)

Bioenergy and bioproducts research is led by Dr. Muhammad T Afzal.

His research focuses on feedstock processing and engineering, pellets, briquettes, modelling of compaction phenomena and thermo-mechanical characterization, feedstock management including its storage, drying, modelling and logistics.

Recently, Dr. Afzal and his team are focusing on design and development of novel technologies to produce renewable fuels, chemicals and value-added products and materials, process modeling and optimization, which can find application in automotive, food, chemical, health and pharmaceutical industry. It is also our goal to discover and promote the use of next generation clean energy through innovative research and education. We are interested in life cycle assessment of materials and products and developing alternate solutions to lessen the environmental impact in manufacturing and usage.

Key ongoing research activities include development of innovative technologies such as microwave heating to process and convert renewable feedstock into fuels, heat, power and bio-products, modeling and simulation of real time process.

We conduct both fundamental and applied research to develop sustainable and innovative solutions to bioenergy and bioproduct applications. BBRL is interested to develop collaborations with industry, academia and national institutes for research in feedstock engineering, conversion technologies and bioproducts from renewable materials.
