Use pistachio skin
Each kilogram of carbon pistachio shell is produced from 12 kilograms of pistachio skin and 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.% D9% be% d9% 88% d8% b3% d8% aa-% d9% be% d8% b3% d8% aa% d9% 87
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 incineration or disposal, 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. .
Production of tar from pistachio bone skin
The most important and valuable product obtained from chemical decomposition of hard pistachio skin due to high heat is tar. On average, about 15-20 ml of tar is obtained from each 100 grams of pistachio peel. Tar is a viscous liquid with a pungent odor that contains a variety of chemical compounds and is obtained from the chemical decomposition of materials such as coal and wood and… due to high heat.
