The Vietnamese cement industry has enormous potential for co-processing waste, especially non-recyclable plastic, as an alternative fuel. According to Associate Professor Luong Duc Long, the vice president of the Vietnam National Cement Association, Vietnam is a significant manufacturer of cement, with an annual production capacity of more than 100 million tonnes.
On September 29 in Hanoi, the Norwegian Embassy hosted a workshop on the co-processing of alternative fuels and raw materials in the Vietnamese cement sector. The workshop is a component of the Norwegian government-funded Ocean Plastic Turned into an Opportunity in Circular Economy (OPTOCE) Project.
Assoc. Prof. Long claimed that the nation’s fuel consumption for cement manufacturing is now high, and there are 82 operational clinker kilns using over 10 million tonnes of anthracite coal annually in the country.
Although the Government has a goal to boost the rate by 15% by 2030 and 30% after that, the usage of alternative fuels in the whole cement sector is still only slightly over the existing low level.
The method of waste co-processing in the cement industry is a solution with many advantages to thoroughly treat all types of waste, including household waste and industrial waste, especially hazardous waste, thanks to a system of incinerators.
Data from the Vietnam Environment Administration shows that Vietnam has issued licenses for co-processing wastes for four cement manufacturers, namely Holcim Hon Chong Cement Factory, Thanh Cong Group Joint Stock Company, Nghi Son Cement Company, and VICEM Ha Tien Cement Joint Stock Company.
