Survey results from 72 mechanical manufacturers in Ho Chi Minh City (HCMC) in conjunction with related studies showed that industrial solid waste – hazardous waste (ISW-HW) treatment charges were operated in two forms: fixed and varied based on generated ISW-HW mass. Charges of collection – transport – storage – treatment – landfill for each waste composition varies widely (5 ÷ 20 fold), depending on the agreement between waste generators and solid waste services. Charges have not yet shown the relationship with treatment technologies, achieved treatment levels, as well as the correlation with transport distance and waste’s toxicity. Methodology for calculating ISW treatment costs by incineration was initially set. Treatment costs per ton of ISW from the mechanical industry were specifically established for each case of emission, corresponding to different payloads of transport means.
