Waste To Energy Solutions Through Torrefaction
Keystone Energy uses its proprietary continuous torrefaction technology to convert any combination of Municipal Solid Waste (MSW), Biomass, Refuse Derived Fuel (RDF), and Sewage Treatment Plant (STP) Sludge into high calorific torrefied fuel, torrefied biomass, torrefied MSW, Green Coal, BioChar and waste to charcoal fuel.
Our torrefaction process produces sustainable and cost effective coal replacement fuel and alternative industrial fuel for thermal power plants, cement plants, steel plants, industrial boilers, biomass co-firing systems and waste to energy infrastructure applications. The torrefaction technology improves calorific value, reduces moisture, stabilises fuel characteristics and enables industrial scale waste to energy conversion and industrial decarbonisation.
Keystone Energy has designed, engineered, commissioned, and deployed industrial-scale continuous torrefaction plants and waste to energy EPC infrastructure projects for National Thermal Power Corporation (NTPC), Delhi Jal Board, municipal corporations and private industrial operators across MSW, RDF, biomass, sludge processing, and waste to charcoal conversion applications.

Complete Torrefaction Solutions
Here is the end to end waste to energy solution procedure:
MSW to Torrefied Charcoal Plants
Keystone Energy provides an end to end EPC solution for setting up plants to convert MSW into Torrefied MSW, Torrefied Coal, Charcoal, Green Coal and BioChar fuel. Complete EPC solution includes designing, engineering, procurement and commissioning of the waste to charcoal plants. The end product, torrefied MSW, is mandated by the Ministry of Power under biomass co-firing mandate to be used by thermal power plants to reduce pollution and increase generation of sustainable energy.
Keystone Energy’s MSW projects include a 500 Tons Per Day MSW to Torrefied MSW plant for NTPC Ltd. in Gorakhpur, Uttar Pradesh.
Biomass to Torrefied Charcoal Plants
Keystone Energy provides industrial scale biomass torrefaction EPC solutions for converting agricultural residue, woody biomass, agro waste and organic biomass to Torrefied Biomass, Torrefied Coal, Charcoal, Green Coal and BioChar fuel. Complete EPC solution includes designing, engineering, procurement and commissioning of the waste to coal plants. The end product, Torrefied Biomass, is mandated by the Ministry of Power to be used by thermal power plants to reduce pollution and increase generation of sustainable energy.
Keystone Energy’s Biomass projects include a 200 Tons Per Day Biomass to Torrefied Biomass plant for TransPacific Engineers in Sangrur, Punjab.
STP Sludge to Torrefied Charcoal Plants
Keystone Energy provides EPC solutions for converting STP sludge torrefaction, sewage sludge processing, biosludge treatment and sludge-to-fuel into Torrefied Coal, Charcoal, Green Coal and BioChar fuel through torrefaction. Complete EPC solution includes designing, engineering, procurement and commissioning of the waste to energy plants. The end product, Torrefied STP Sludge, helps convert high moisture waste to usable fuel.
Keystone Energy’s STP Sludge projects include a 50 Tons Per Day STP Sludge to Torrefied Charcoal pilot plant for Delhi Jal Board in Delhi.
THE SOLUTION IS GREEN COAL
01
Feedstock
We utilize the untreated, non recycled, and non used waste as our input
