Abstract: The present invention relates to an integrated automated biorefinery system and method for harvesting, fractionating, and converting Parthenium hysterophorus biomass into multiple renewable fuels and value-added products through intelligent mechanical harvesting, continuous chemical fractionation, biochemical conversion, thermochemical processing, and automated process control. The system comprises an intelligent harvesting device, a continuous biomass fractionation unit, an alkaline delignification unit, hydrolysis and fermentation modules, a fractional distillation unit, a thermochemical pyrolysis system, and an embedded automation and monitoring architecture. The biomass undergoes dilute acid pretreatment to produce hemicellulose-rich and cellulose–lignin-rich fractions, followed by alkaline delignification to recover cellulose and lignin. The recovered sugars are hydrolysed and fermented to produce bioethanol, while lignin is converted into pyrolytic bio-oil and biochar through oxygen-limited pyrolysis. The process further enables recovery of fermentation-derived humic matter, ensuring comprehensive biomass utilization. Integrated sensors, embedded controllers, and closed-loop control algorithms continuously monitor and regulate process parameters to improve efficiency, safety, and process reliability. The invention provides a sustainable, scalable, and economically viable solution for managing the invasive weed Parthenium hysterophorus while producing cellulose, hemicellulose, lignin, bioethanol, pyrolytic bio-oil, biochar, and humic matter for applications in renewable energy, biomass processing, agricultural waste management, and environmental remediation.
