1. Overview of Waste Management

Waste processing, or waste management, encompasses a series of processes to control waste from its generation until its final treatment. This industry plays a crucial role in minimizing the negative impact of waste on the environment and human health. Its primary focus is on municipal waste, generated by industrial, commercial, and household activities.

In Vietnam, the amount of industrial and household waste is increasing due to rapid economic development, a growing population, and significant industrialization. According to the latest statistics from the Ministry of Natural Resources and Environment (February 2023), the daily generation of solid household waste in Vietnam is approximately 60,000 tons (about 21.9 million tons annually), and this amount is still rising due to population growth.

Many landfills in Vietnam are showing signs of overload

Simultaneously, waste management in Vietnam still faces numerous limitations, employing three main methods: landfilling, incineration, and sending waste to compost production facilities. Among these, landfilling is the predominant method, accounting for 71% of the total waste volume, utilizing simple techniques, and often associated with unsanitary landfills. Approximately 16% of the waste is processed in compost production facilities, while only 13% undergoes incineration. The current incineration technology used in Vietnam mainly involves small-capacity incinerators (below 300kg/hour), with many lacking exhaust gas treatment systems or not meeting the required standards.

From this current situation, it is evident that waste management is a significant challenge in Vietnam. However, it also represents a lucrative opportunity for investors and a chance to leverage the potential of industrial boilers.

2. Applications of boilers in waste management

Boilers play a crucial role in the waste management industry, transforming waste into useful energy for both production and daily life through the incineration process. Before incineration, industrial and household waste is sorted to eliminate items that may produce harmful substances during combustion or items that cannot be burned, aiming to maximize efficiency.

After this process, the waste will be incinerated in the boiler combustion chamber to generate heat energy used in the following activities:

- Generating steam for production purposes: The heat produced by heating water in the boiler generates steam, meeting energy demands in various manufacturing industries. This process optimizes energy utilization and reduces production costs.

The 35 TPH fluidized bed boiler manufactured and installed by Martech for the Thuan An Paper Factory helps save over 30 billion VND in fuel costs annually by utilizing waste and sludge generated during the operation process for combustion in the boiler.

- Power generation: The heat generated from the combustion process is transferred to the water pipeline system. In this process, the water in the pipes will increase in temperature to the boiling point. Consequently, hot steam is produced and conveyed through the boiler's superheater to create superheated steam. This superheated steam is then used to operate the turbines of the power plant and generate electricity. This process is commonly found in modern waste-to-energy plants, contributing to a sustainable power supply for the country.

Martech provides a waste-fueled fluidized bed boiler for power generation to the Dong Hai Paper Factory in Ben Tre

The integration of boilers with waste processing not only helps alleviate the pressure on traditional energy sources (coal, oil, etc.) but also contributes to reducing the amount of waste released into the environment. This is an effective way to promote sustainability in the waste management industry and protect the environment.
