The sustainable green connected systems are considered as the engine room for fostering the Green- Clean Campuses. The biomass management with organic cycles is crucial factor in tropical sustainable campuses as it tends to produce a huge amount of biomass with multiple organic cycles. This proposed biorefinery model at Chemperi, Kerala which is in tropical region can connect Agri farming, pisciculture, piggery farming, and livestock farming for waste management with a centralized aerobic-anaerobic sewage recycling system. The model has proven benefits of cost optimization, reduced fuel conception, enhancing biodiversity with a sustainable ecosystem, and foster sustainability. The output of these multiple farming provides fresh raw materials for the kitchen with economic and health benefits. This model established at Vimal Jyothi Campus, Chemperi, Kerala found to reduce biomass waste production, biorefinery waste management with energy-saving, inculcating sustainability practices in campus and establishment of Green Clean Campus. The model can be integrated with intelligent monitoring systems and automation.
