Hydrothermal carbonization is an environmentally friendly method that converts raw biomass into material resources of high value. In recent years scientists have been conducting concerted efforts to minimize food waste accumulation and pollution by turning towards biomass vapourisation. In the current global climate, it is a massive challenge to satisfy the demand for energy while also reducing the associated environmental degradation. Using biomass as a renewable energy source to combat these energy issues is becoming more and more relevant. In the present study, sesame oilcake and groundnut oilcake- vastly used as fodder for animal and considered waste, were converted into porous carbon  and the applicability of hydrochar carbon was ascertained using several characterization techniques, namely FTIR, SEM, proximate analysis, EDAX and TGA. The physical analysis inferred that the examined oil cakes contained lower carbon and oxygen content indicating high protein and energy contents. EDAX analysis of samples confirmed the applicability of produced hydrochars as nutritional supplements for plants.
