Abstract

n

nHydrothermal Carbonization (HTC) is an innovative technology that is mimics of natural coal formation processes to convert wet biomass into valuable carbon-rich materials known as “biochar.” This process involves subjecting organic matter, like agricultural waste, food residues, or sewage sludge, under high-pressure & moderate-temperature conditions (around 180-250°C & 2-4 MPa) in presence of water. HTC technology accelerates process of  the dehydration & carbonization of biomass, thus producing a solid product with improved energy density, which can find various applications such as fuel, soil amendments, and a precursor for activated carbon production. HTC process is a sustainable solution to effectively manage biomass waste including waste tires and creating value-added products. The biochar produced through HTC has high surface area, and can be customized for specific applications. HTC is an effective means of carbon sequestration, helping mitigate climate change by locking carbon in solid form and significantly reducing greenhouse gas emissions. Moreover, HTC technology reduces the volume of waste material, leading to waste-to-energy strategies & promoting a circular economy. HTC technology’s versatility offers to process a wide range of feedstocks, including those that are too wet or difficult to handle with other biomass conversion technologies. HTC’s integration with existing waste management and energy systems holds great potential for addressing global challenges related to waste disposal, renewable energy generation, and sustainable agriculture. As research and development progress, HTC technology has the potential to play a significant role in future energy and environmental solutions. This review article briefly describes basic HTC technology, its usage in Tire Pyrolysis, superiority as compared other recycling technologies and challenges & limitations.nn
