Dong Nai province in Vietnam is pushing a circular economy by turning agricultural and forestry by-products into biochar and other carbon materials. The province has one of the country's largest livestock populations and major fruit and industrial crop areas, so the feedstock supply is substantial. Local officials are working with Queensland University of Technology to study new conversion technologies and build links between research and commercial use. Current models include using indigenous microorganisms, sorting waste at source, and turning cocoa husks, cashew shells, and coffee beans into biochar. There is also interest in producing activated carbon for batteries, which could connect Vietnamese waste processing to a growing supply chain. The article is a useful look at how waste-to-carbon projects move from conference discussions to practical agricultural and industrial applications.
