Use of green pistachio shell:

Preparation of jams and pickles

Carpet fiber dyeing

Edible mushroom production substrate

Animal feed

Preparation of organic fertilizers

Extraction of oil from pistachio keel waste

Use of pistachio bone shell:

Production of activated carbon

Tar production

As it tus out, the two most important parts of pistachio waste are its soft skin and bones. In the following, we will discuss the applications of soft and bony pistachio shell.

Pistachio bone shell applications

Activated carbon and tar are the most unique and lucrative by-products of pistachio bone shell. Pistachio ossicle shell is very suitable for activated carbon production due to its volatile and high carbon content, low ash content and good hardness properties. In many countries, such as Turkey, where fuel is very expensive, the use of this product is very well received. The pistachio shell of the pistachio during the pyrolysis process (Azarkaft) produces two valuable products of tar and carbon. It is worth mentioning that pyrolysis is the thermal decomposition of materials at high temperatures and in neutral atmospheres. Pyrolysis is mainly used in the processing of organic materials.

Tar is the most valuable product obtained from the chemical decomposition of hard pistachio shells due to high heat. On average, about 15 to 20 ml of tar is obtained from every 100 grams of pistachio bone shell. Tar is a viscous liquid with a specific odor that is obtained by chemical decomposition of materials such as coal, pistachio shell and.. Herbal tar is commonly used in the pharmaceutical and cosmetic industries. The tar in pistachio shell is in the edible category due to its high index.

Activated carbon

In the final stage of the pyrolysis process, some coal remains. During the activation operation, activated carbon is produced. Activated carbon is used as a filter in oil refining and beverage production. Activated carbon can also be used as a separator of toxic gases from the air. According to research, 1 kg of activated carbon is extracted from 12 kg of pistachio shell.
