Iranian Knowledge-Based Company Turns Oil Sludge, Urban Sewage Waste into Usable Products
Ali Khani, a Ph.D. graduate in applied chemistry-environmental engineering and a faculty member of Islamic Azad University’s Mianeh branch, along with Ali Rasoulzadeh, the founder of the knowledge-based company, are the manufacturers of the multi-functional co-pyrolysis system for recycling all types of urban, industrial and agricultural waste in Iran.
“Our knowledge-based company has succeeded in producing the multifunctional co-pyrolysis device which is used for recycling all types of worthless rejected waste,” Khani told ANA.
The device converts urban, hospital and industrial polymer wastes, including non-recyclable plastic and rubber wastes, into hydrocarbons for diesel fuel and carbon black, greenhouse wastes and agricultural wastes into wood vinegar and biochar, oil sludge resulted from drilling operations, oil transfer and refinery operations into oil derivatives, and sludge from urban sewage treatment and wet urban waste into biochar, he added
Noting that no such technology has existed in Iran so far, Khani said that compared to foreign models, the Iran-made device is more efficient, less pollutant and higher quality and it is capable of multitasking.
Biochar is a charcoal-like substance that’s made by burning organic material from agricultural and forestry wastes (also called biomass) in a controlled process called pyrolysis.
Although it looks a lot like common charcoal, biochar is produced using a specific process to reduce contamination and safely store carbon. During pyrolysis organic materials, such as wood chips, leaf litter or dead plants, are burned in a container with very little oxygen. As the materials burn, they release little to no contaminating fumes.
During the pyrolysis process, the organic material is converted into biochar, a stable form of carbon that can’t easily escape into the atmosphere. The energy or heat created during pyrolysis can be captured and used as a form of clean energy. Biochar is by far more efficient at converting carbon into a stable form and is cleaner than other forms of charcoal.
