The Industry at a Glance
The global waste-to-energy market was valued at USD 42.34 billion in 2024 and is projected to grow to USD 78.49 billion by 2033, at a CAGR of 7.10%. Governments across developed and emerging economies are implementing strict regulations to curb landfill usage and reduce greenhouse gas emissions, creating a favorable environment for advanced incineration technologies. As emission standards tighten globally, oxygen-enriched combustion is emerging as a key upgrade path for waste-to-energy plants seeking higher efficiency, lower pollutants, and better regulatory compliance.
Where Our Products Are Used
-
1
Municipal Solid Waste (MSW) Oxygen-Enriched Incineration
The air is enriched to 25%–30% oxygen and sent to the incinerator as secondary air, boosting combustion temperature and completeness.
-
2
Hazardous Waste Thermal Treatment
VPSA oxygen supply supports high-temperature oxidation in hazardous waste incinerators, ensuring thorough destruction of toxic organic compounds at >850°C.
-
3
Ozone-Based Wastewater Treatment
Oxygen is widely used in environmental protection including wastewater treatment and waste burning; VPSA-generated oxygen feeds ozone systems for advanced oxidation of industrial and municipal wastewater.
-
4
Flue Gas Desulfurization & Denitrification
The desulfurization and denitrification reactors (SDS) and ozone oxidation reactors in thermal power plants, as well as the ozone oxygen supply systems in municipal sewage and waste incineration plants, are all compatible with VPSA oxygen generation.
Pain Points & Solutions
-
The Challenge
Incomplete combustion at standard air oxygen levels (21%) generates dioxins, excessive slag, and toxic flue gases — creating compliance risks under tightening emission standards.
Our SolutionThe increased oxygen elevates the ignition conditions and makes the combustion more complete by smelting the slag and reducing it to nearly none, ensuring the complete decomposition and combustion of dioxins and other toxic organic gases at high temperatures.
-
The Challenge
Liquid oxygen procurement is costly, logistically complex, and creates supply chain dependency — especially for remote or large-capacity incineration facilities.
Our SolutionVPSA oxygen generation with energy consumption as low as ~0.30 kWh/Nm³ eliminates transport reliance and delivers continuous, cost-effective oxygen on demand.
-
The Challenge
Waste incineration plants need reliable 24/7 oxygen supply, but operating specialized gas equipment diverts resources from core waste management operations.
Our SolutionBy renting VPSA oxygen equipment, users could transfer their important but non-core VPSA oxygen supply duties to the professional gas company PKU Pioneer, with full O&M and remote monitoring support.
