Groundnut shell briquettes are an eco-friendly and renewable source of biofuel made from the compressed shells of groundnuts (peanuts). These cylindrical or block-shaped briquettes are crafted through a process that involves collecting, drying, and compressing the agricultural waste material, resulting in a high-density and energy-efficient product. Groundnut shell briquettes are ideal for various heating and energy applications, including residential stoves, industrial boilers, and power generation. They have a high calorific value, low ash content, and produce minimal smoke during combustion, making them an environmentally friendly alternative to conventional fossil fuels such as coal or wood. Their production not only utilizes agricultural waste effectively but also reduces the carbon footprint of energy systems by promoting sustainable energy use. These briquettes are compact, easy to transport, and store due to their uniform shape and size. Their adoption is growing across industries and households seeking affordable, sustainable, and clean energy solutions.
