Bhubaneswar: Housing and Urban Development (H&UD) Minister Krushna Chandra Mahapatra visited the ‘waste-to-charcoal plant’ at Ramana in Varanasi Friday, to study its innovative zero residue green technology for Municipal Solid Waste (MSW) management.
The plant demonstrates the torrefaction process, a thermochemical treatment of waste at 250 to 300 degrees Celsius in a controlled oxygen environment.
Through this process, moisture and volatile matter are removed, and the waste is transformed into torrefied charcoal, a hydrophobic, high-calorific-value, carbon-rich fuel that can effectively substitute fossil coal.
Mahapatra commended the initiative and said, “The Ramana waste-to-charcoal plant at Varanasi is a path-breaking model for sustainable solid waste management.
Turning garbage into green fuel eliminates landfills, reduces carbon emissions, and contributes to energy security.
Odisha is determined to replicate such innovative, zero-residue technologies in our cities to build a cleaner and greener future.”
A 400 tonne per day (TPD) plant can prevent 13 TPD methane emissions, earning nearly 390 carbon credits by same-day processing of waste.
It can generate 100 TPD of green charcoal, replacing an equal amount of fossil coal.
This substitution translates into a saving of 250 to 290 TPD of carbon emissions, offering significant climate benefits.
The minister was accompanied by the H&UD department’s additional secretary Binaya Kumar Dash, NTPC DGM (WTE), Varanasi Ashish Ranjan and other key officers.
Varanasi Municipal Corporation has already earmarked 16 acres of land along with trunk infrastructure support for the facility.
Significantly, NTPC has adopted this model under its CSR initiative and is successfully using the torrefied charcoal in its thermal power plants, reducing reliance on conventional coal.
