Choosing technology for solid waste treatment
According to the documents of Vietnam Institute for Planning and Development, every year the country must receive a volume of solid waste up to 12 million tons. This number is continuing to increase at a rate of about 9% / year, proportional to the growth rate of the economy, as a rule: the living standard increases, the waste also increases. Therefore, managing waste disposal activities is always set out to be a very important and urgent task to protect the public health and environment.
Mr. Pham Van Tan - Vice President and Secretary General of VUSTA
On December 16, in Hanoi, Vietnam Union of Science and Technology Associations held the Seminar on Waste Treatment Technology. Mr. Pham Van Tan - Vice President and Secretary General of the Vietnam Union and Mr. Dang Huy Dong - Director of the Institute for Planning and Development co-chaired the seminar.
The concern of the Government, the Ministry of Natural Resources and Environment and the local authorities in the waste issue is always appreciated. Specifically, in terms of institutions and policies, there can be a series of governmental laws and decrees, as well as a lot of circulars issued by relevant ministries and localities; The central and local budgets have also spent thousands of billion dong each year for the waste management and treatment.
However, It must be admitted that the results obtained is still far away from the expectations of both people and the government and do not commensurate with the costs and resources spent. Unfortunately, it is a fact that we have to objectively acknowledge and evaluate in order to have a solution to overcome it.
The delegates discussed and gave many opinions at the seminar
At the seminar, delegates discussed two issues: Should we bury or burn generating biomass? According to many delegates' opinion, the burial is not satisfactory because it has waterproof lining, wall, waste water collection and treatment system, methane collection to detect, only bury the remaining things after sorting for recycling, reuse, compost, however with this model only effective when garbage is sorted upstream.
However, at the seminar, some delegates said that, at present, "garbage electricity" is the keyword widely used through the mass media, this measure is being strongly encouraged as a perfect solution to handle today's garbage problem.
Additionally, many delegates said that burning waste to generate electricity has really identified garbage as a resource, which help contribute to national energy security ... and beyond that, this is also considered a solution to implement the cyclic economy.
However, from the perspective of experts and scientists, a series of questions have been posed with this technology.
Specifically: Is incineration technology really a new technology? Does incineration generate electricity as expected? Does garbage electricity really clean the environment?
Views of the seminar
At the seminar, the participants had the opportunity to get access to information about solid waste treatment technology trends in the world, including solid waste gasification technology; capture the latest information on the implementation of experimental projects on solid waste treatment technology by gasification (not waste incineration), entirely owned by Vietnam.
