Sensitivity Analysis
Sensitivity analysis in advanced thermal gasification is crucial for understanding how different operational parameters impact the process's efficiency and costs.
Effect of Process Gas Flow Rate
Increasing the flow rate of process gas decreases syngas production.
Effect of MSW Flow Rate
Increasing the municipal solid waste (MSW) flow rate results in increased syngas production.
Energy Efficiency
Achieving a higher cold gas efficiency (CGE) is more crucial than reducing thermal power consumption for better energy efficiency.
CGE is a crucial metric for maximizing energy output while minimizing operational cost.
Operational Parameters
Sensitivity analysis aims to:
- Maximize net energy produced
- Minimize costs of the plant
- Optimize syngas quality
- Balance efficiency and operational expenses
Applications and Considerations

Challenges Faced by Other Waste-To-Energy Plants and Causes of Their Failures
While traditional Waste-to-Energy (WTE) plants have been implemented across India and globally, many face significant operational, environmental, and economic challenges that have led to underperformance or complete failure. Understanding these challenges highlights why our advanced technology offers a superior alternative.
Common Challenges in Traditional WTE Plants
1. High Dioxin and Furan Emissions
Traditional incineration plants operating below 850-1000°C produce carcinogenic dioxins and furans, which are major sources of cancer and health issues. These toxic compounds are released into the atmosphere, into the atmosphere, affecting nearby populations. Our technology eliminates this issue entirely by operating at 3000°C+, completely destroying these harmful compounds.
2. Extensive Segregation Requirements
Most WTE plants require extensive waste segregation (wet/dry, organic/inorganic, recyclable/non-recyclable), which is labor-intensive, costly, and often poorly implemented in developing nations. Poor segregation leads to inefficient combustion and higher emissions. Our Advanced Gasification requires minimal segregation, processing mixed waste streams effectively.
3. Large Residue Volumes
Incineration produces 40+ kg of ash and residue per ton of MSW, which must be landfilled, creating ongoing disposal challenges and costs. Our process produces only 15 kg of vitrified slag per ton – a 62.5% reduction – and this slag is non-toxic and usable in construction.
4. Inability to Handle Hazardous Waste
Traditional WTE plants cannot safely process biomedical, chemical, or hazardous industrial waste due to toxic emissions and incomplete combustion. We safely destroy all types of hazardous waste at ultra-high temperatures with zero toxic byproducts.
5. Positive Carbon Footprint
Any incineration plants have a positive CO₂ footprint, contributing to greenhouse gas emissions rather than reducing them. Our technology has a negative carbon footprint of -31 kg CO₂ per ton of MSW, actively reducing greenhouse gases.
6. Low Waste Diversion Rates
Traditional WTE plants achieve only 60-70% waste diversion, with the remaining 30-40% ending up in landfills. We achieve 95% waste diversion, virtually eliminating landfill dependency.
7. Air and Water Pollution
Leachate from ash disposal contaminates groundwater, and emissions (even after scrubbing) contain harmful particulates, heavy metals, and acidic gases. Advanced Gasification produces inert slag with zero leaching potential and emissions that meet the strictest CPCB standards.
8. Public Opposition and NIMBY (Not In My Backyard)
Communities near incineration plants often protest due to health concerns, odor, and pollution. This has have led to shutdowns and project cancellations. Advanced technology's clean operation and zero harmful emissions make it more socially acceptable and sustainable.
9. High Maintenance and Downtime
Corrosion from acidic gases, fouling of heat exchangers, and frequent breakdowns plague traditional WTE plants, reducing operational efficiency and increasing costs. Our sealed, high-temperature process reduces corrosion and maintenance requirements.
10. Regulatory Non-Compliance
Many WTE plants struggle to meet emission standards set by CPCB, SPCB, and international bodies, leading to fines, operational restrictions, or closures. Advanced Indigenous Technology inherently meets or exceeds all regulatory requirements due to its clean operation.
