Waste combustion – Oxoco

Waste combustion,
comparison with conventional technologies

ASPECT and IMPACTS	Traditional incinerators	Flameless Isotherm PWR Technology
SOLID EMISSIONS (from the process)	Ashes (heavy and light) to landfill or other forms of treatment	No ashes generation by the process

ASPECT and IMPACTS	Traditional incinerators	Flameless Isotherm PWR Technology
MATERIAL RECOVERY	No matter recovery	Output: – Vitrified beads, 100% Secondary raw material, classified as End of Waste, that can replace minerals in production cycles; – Carbon dioxide (CO2): 40,000 tons/year (ref. 15 MWt Plant) exploitable in the industrial technical gas sector; – Water– H2O, up to 10.000 tons/year transferable to third parties (ref. 15 MWt plant).

ASPECT and IMPACTS	Traditional incinerators	Flameless Isotherm PWR Technology
WATER RESOURCE	Continuous exploitation of the water resources..	No exploitation of the water resources The Isotherm plant reuses water condensed in the plant itself and is able to release clean water to third parties for more than 15 percent of what produced.

ASPECT and IMPACTS	Traditional incinerators	Flameless Isotherm PWR Technology
WATER RELEASE	Discharge of wastewater that is purified and subsequently discharged into the sewer.	Reuse of produced water;(no discharge into sewer): – 85% internally to the process – 15% externally to the process (clean water usable by third parties).

ASPECT and IMPACTS	Traditional incinerators	Flameless Isotherm PWR Technology
GAS EMISSIONS dioxins-furans PAH PCB	Quality of emitted fumes Emissions of organic pollutants complying to the law standard after fume purification. emitted Fumes : 4000 – 6000 Nmc per ton of waste	Quality of emitted fumes Emissions of organic pollutants about 100 times lower than law standards without specific fume purification. Emitted Fumes : 100 – 400 Nmc* per ton of waste (*only during standby periods of the CO2 recovery system)

ASPECT and IMPACTS	Traditional incinerators	Flameless Isotherm PWR Technology
GREENHOUSE GAS EMISSION	Complete release of greenhouse gases (climate-altering) produced	Carbon dioxide (CO2)capture and storage for industrial use.

ASPECT and IMPACTS	Traditional incinerators	Flameless Isotherm PWR Technology
ENERGY PRODUCTION	Thermal energy production efficieny between 70% and 90%	Thermal energy production efficiency greater than 90%

ASPECT and IMPACTS	Traditional incinerators	Flameless Isotherm PWR Technology
CAPEX/OPEX		The Isotherm PWR® plant requires capital expeditures (CAPEX) much lower than conventional incinerator of similar capacity (less than 50%). Operating expeditures (OPEX) in the range of 75-80% of the operating cost of a conventional plant.
