Iran produces diesel, black carbon from wastewater for first time

The chief executive of the Tehran Sewage Company announced the production of diesel and black carbon from dewatered sludge in the process of wastewater treatment plants in the Iranian capital.
It is hoped that production of diesel and black carbon will be operationalized in the current year (started March 20, 2024), Abbasali Mesrzadeh stated, as reported by IRNA.
As black carbon is used as the raw material in industries, especially in the tire manufacturing industry, he noted that its production in the process of wastewater treatment can both create added value and prevent environmental pollution.
Converting 120 tons of sludge daily to diesel and black carbon is the company’s main plan in the current year, he said, stressing that it can be used in the heating system of the wastewater treatment plants and facilities related to it.
At first glance, sewage and wastewater are considered a source of pollution and threat to human communities, the official said, noting that what comes to pass in hygienic sewage collection projects is turning threats into opportunities.
Iran is one of the leading countries in the Middle East in the generation of electricity from sewage. In addition to generating electricity at the wastewater power plants, the heat caused by the gas engines is used to replace fossil fuels for providing warmwater, he added.
