🔥 Waste Incineration and Recycling – A Sustainable Path for Vietnam’s Environmental Sector

Vietnam’s environmental sector is actively promoting the development of integrated waste treatment and recycling complexes, attracting investment in advanced technologies. Among the most widely adopted solutions are waste-to-energy incineration systems, which combine co-incineration and cogeneration to maximize efficiency in waste disposal and energy recovery.

🎯 Technology Objectives:

High-capacity waste treatment, ranging from 500 to over 1,000 tons per day, with continuous operation.
Utilization of high calorific value waste as alternative fuel, reducing dependence on fossil fuels.
Fuel transition from HFO (Heavy Fuel Oil) to multi-fuel systems.
Energy recovery: generating thermal energy, electricity, and steam for internal use and grid integration.
Ash and residue recycling, contributing to pollution reduction and circular economy development.

🔄 Waste Incineration Process:

Collection – Sorting – Feeding into the incinerator.
Combustion at high temperatures (850°C – 1000°C) for complete waste oxidation.
Heat recovery via boiler heat exchange surfaces → producing high-pressure steam.
Steam drives turbines → converting thermal energy into mechanical energy → generating electricity.
Electricity is used internally and exported to the national grid.
Condensed water is recovered and reused in a closed-loop system.

🌫️ Emissions and Air Pollution Control:

The incineration and metal smelting processes generate high-temperature exhaust gases containing hazardous substances such as CO, NOx, SOx, and heavy metals (e.g., manganese, lead). It is essential to implement air pollution control systems that comply with QCVN 19:2024/BTNMT, the national technical regulation on industrial emissions for dust and inorganic substances.

♻️ Ash and Waste Recycling:

Incinerator ash is chemically stabilized, sorted, and recycled into: non-fired bricks, additives for cement and concrete production.
Other recyclable materials include:
– Metals (iron, aluminum, copper), plastics.
– Industrial sludge → processed into agricultural fertilizers.
– Non-ferrous metal residues → reused as raw materials.
– Solar panel waste → treated through specialized processes.

FILTRATION OF WASTE INCINERATION – RECYCLING INDUSTRIES

TAN THANH FILTRATION: Industrial applications of waste incinerators and recycling have been strongly developed recently to solve the problem of waste treatment and environmental protection. However, there are still some disadvantages such as the possibility of dust emission during the waste incineration process. To overcome this problem, Tan Thanh Company has proposed filtering treatment solutions to minimize the emission of polluting dust and toxic gases during the waste incineration process, ensuring safety for human health and environmental protection.

Contact the engineering team: Mr. Kelvin: 0917 531 007 and Mr. Binh: 0919 823 239for design, manufacture and construction of incinerator dust treatment system.

GUTSCHE: “In order to generate electricity from municipal waste or RDF, modern Energy from Waste plants with optimised flue gas cleaning systems are used. The aim of flue gas cleaning is to chemically neutralise the harmful gases, reduce pollutants such as dioxins, furans and heavy metals and to remove the particulate in the gas with an efficiency of greater than 99.99%. Highly efficient bag filters are used to effectively remove the dust particles and reacted product.” (Application areas. Waste and RDF Combustion. June, 2025. Gutsche)

Incinerator exhaust gas treatment process

Exhaust gas from the incinerator is led through each dust and exhaust gas treatment system, along with dust explosion prevention measures as follows:

Dust separation by electrostatic dust extraction system:
– Use the suction force of the air flow passing through the electric field to separate small dust particles (from a few microns or more) from the exhaust gas stream.
– The system needs to install high-tech explosion prevention equipment such as: isolation valve, chemical isolation system, probe device, combined with mechanical equipment such as rotary valve, explosion discharge door, etc.
Dust separation and filtration by filter bag/cartridge dust collector system:
– The remaining dust particles continue to be filtered and separated by the negative pressure fabric filter bag/cartridge dust collector system.
– The dust filter bag and filter bag cage are made from heat-resistant and chemical-resistant materials, helping to remove fine dust particles and dust particles from the exhaust gas stream that has passed through the electrostatic filtration system.
– The system needs to install explosion prevention equipment from the early stages of the explosion, including controllers, pressure probes, chemical discharge tanks and special telescopic nozzles.
Waste gas neutralization treatment:
– Acid gas absorption treatment, removing acid gases such as SO₂ and HCl.
– NOx removal treatment through selective catalytic reduction (SCR) or selective non-catalytic reduction (SNCR) technologies, converting NOx into N₂ and H₂O.
– Dioxin/Furans treatment through the use of activated carbon.
Heat recovery, waste gas cooling:
– Heat recovery for reuse (heat recirculation).
– Cooling, condensing to treat and recover dust and remaining liquid.
– Each waste gas cooling method (by water, cooling tower or heat exchanger) depends on many factors, including the temperature and flow of the waste gas, the temperature requirements after cooling and the environmental factors after treatment, while can meet the requirements of heat and waste gas recirculation.
Emission monitoring/measurement:
– Monitoring and recording of waste gas indicators, complying with safety and environmental hygiene regulations. A system can include devices to measure dust concentration, waste gas (such as CO, SOx, NOx), flow, temperature, pressure, etc. and transmit data to the control center for monitoring and analysis.
