TEHRAN - The head of the Tehran Sewage Company announced the production of diesel and black carbon from de-watered sludge in the process of wastewater treatment plants in the Iranian capital.

It is hoped that the production of diesel and black carbon will be operationalized in the current year (started March 20, 2024), Abbasali Mesrzadeh stated.

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 main program of the company in the current year, he said.

It can be used in the heating system of the wastewater treatment plants and facilities related to it, he emphasized.

At first glance, sewage and wastewater are considered a source of pollution and threat to human communities, he said, noting that what happened in the hygienic sewage collection project is that the threat is turned into an opportunity, Mesrzadeh added.

Iran is one of the leading countries in West Asia in generation of electricity from sewage. In addition to generating electricity at the wastewater power plants, the heat caused by the gas-burning engines is used to replace fossil fuels for providing warmwater, he added.
