Deputy Minister of Science and Technology Tran Hong Thai said that research and technology transfer directions need to solve environmental problems and utilize waste as a resource.
The information was presented by Deputy Minister Thai at the workshop "Technology for treating domestic solid waste - current situation and solutions" held in Ben Tre on the morning of December 9. The workshop aimed to provide an overview of the current situation of waste in the Mekong Delta as well as introduce waste treatment technology solutions being applied domestically and internationally by experts, scientists and businesses.

Looking at the current situation of household waste, Mr. Thai assessed that population growth, urbanization and economic development have led to an increasing amount of solid waste, not only in urban areas but also in rural areas. This has a negative impact on the environment, posing challenges in waste management and public health protection.
Expressing his views on waste treatment technology, Deputy Minister Thai said that finding and selecting appropriate solutions must ensure that they do not pollute the environment and that waste can be used as a resource. He said that this is an issue not only in the Mekong Delta but also of concern to many localities in recent times.
According to Deputy Minister Thai, the Ministry of Science and Technology is currently promoting support for scientific research and technological innovation through scientific programs and tasks, contributing to promoting the development and application of waste treatment technology in practice. He hopes for timely coordination between agencies, ministries, sectors and localities as well as businesses, institutes and researchers to thoroughly resolve challenges in waste treatment. Practical applications of waste treatment technology solutions need to be implemented comprehensively, in accordance with Vietnam's conditions.

At the workshop, the business representative introduced the technology of waste gasification. The special feature of this technology is that it is not picky about the input waste, meaning that there is no need to classify the waste before processing. The waste goes through many stages of separation and classification by machine. The drying system will reduce the moisture content of the waste and put it into the gasification furnace to decompose the waste at a temperature of 400 degrees Celsius in an oxygen-deficient condition. The decomposition process will create the final product, biochar, which can be used for cultivation and effective soil improvement, in line with the trend of using black soil in the world. In addition, this technology is said to emit very low concentrations of emissions and does not create wastewater that pollutes the environment.
