However, at present, most of the unsanitary landfills do not have statistics on the amount of solid waste discharged, as well as data on monitoring the environmental status - This is necessary information for managers to come up with feasible options for environmental treatment and restoration at landfills. This paper presents a case study at Suoi Rao unsanitary landfill in Chau Duc district, Ba Ria - Vung Tau province with the following objectives: Determine the amount of solid waste to be buried; Evaluation of composition and characteristics of solid waste at the landfill, the research results show that: there are 6,387 tons of solid waste buried at Suoi Rao landfill, 12 times lower than the forecast of the Department of Natural Resources and Environment (76,295 tons); Most of the waste has been decomposed with easily biodegradable organic components accounting for 1.85% and non-biodegradable components accounting for 27.28%, the rest after classification (soil, sand, humus) accounts for 69%; The content of heavy metals in the soil of solid wastes buried at Suoi Rao landfill are all within the permissible standards, therefore, the impact of heavy metal content in the soil of Suoi Rao landfill to the surrounding environment is low. The research results have important implications for management levels in Chau Duc district to come up with feasible plans in line with reality to treat, renovate and restore the environment of Suoi Rao landfill in the future.
