Md Nasir Hossain Sani

I am passionate about advancing the circular bioeconomy by transforming biogas digestate and organic residues into high-value agricultural products, including circular nutrient fertilizers, biochar, and plant biostimulants. My research combines biological and thermochemical approaches to develop innovative upcycling strategies that close nutrient loops, enhance resource efficiency, and support sustainable, climate-resilient food production. By linking waste valorization with soil and plant system dynamics, I aim to create science-based solutions that strengthen soil health, boost plant growth, and drive the transition toward circular horticulture and a regenerative bioeconomy. 

• Upcycling biogas digestate into biofertilizers, biochar, and biostimulants
• Development and application of sustainable plant biostimulants
• Extraction of proteins and biostimulants from aquatic plants
• Plant physiological dynamics and gas exchange
• Circular horticulture using recycled and sustainable products

Bachelor of Science in Agriculture (2015), Sher-e-Bangla Agricultural University, Bangladesh

My main research is linked to the Biogas Solutions Research Center, Linköping, Sweden, and focuses on the valorization of biogas digestate for sustainable agricultural applications. I am also involved in the EU Horizon project ECOWINS, contributing to a networking platform for best practices in agroecological intensification, including field applications of digestate and biostimulants in diverse intercropping systems, to promote scientific excellence and international collaboration.
