Use pistachio skin Each kilogram of carbon is produced from 12 kilograms of pistachio skin and pistachio shell the export of pistachio skin along with its kernel to other countries should be stopped as soon as possible. Some countries consider pure carbon production to be one of their most lucrative industries, and even produce carbon from almond skins and palm kernels and coconuts. Due to the high volume of pistachio production in Rafsanjan and Kerman province, we can use this feature and turn Iran into a producer of pure carbon using agricultural by-products. Pistachio peel, which is a type of renewable energy, is used to obtain biogas. These products are turned into waste in most of the country's gardens and have no destiny other than destruction, but they can be converted to pure carbon, thus creating significant currency savings for the country. Among the industrial applications of pistachio bone skin, the following can be mentioned: Tar production Production of activated carbon Given that the hard skin covers the brain and is present in large quantities in most parts of the country, it is better to use this seemingly worthless shell. An optimal use is that instead of burning or disposing, it is chemically decomposed by high heat (pyrolysis), and by designing and constructing relevant industrial units and refineries dedicated to this work, valuable materials are obtained from it. .
