The purpose of this study was to evaluate economic feasibility on the fabrication of activated carbon and silica particles from rice straw waste. Several economic evaluation parameters were analyzed for informing the potential production of valuable material from rice straw, including gross profit margin, internal rate return, payback period, net present value, and so on. The result showed that the production of activated carbon and silica particles from rice straw waste is prospective. The engineering analysis for converting 20 kg of rice straw waste per batch shows the total purchased equipment cost of USD 4,900. Adding the Lang Factor, the total investment cost should be less than USD 22,000. This value is relatively economical (i.e., project needs less investment fund) for degrading 67 tons per year or 1344 tons per 20 years of project. Compared to the total amount of degraded rice straw waste, the value will be only about 16 USD per ton. Indeed, this is not expensive for accessing a problem solver in degrading one ton of rice straw waste. To ensure the feasibility of the project, the project were estimated from the ideal condition to the worst cases in the production, including labor, sales, raw material, utility, as well as external condition (i.e., tax and subsidiary). © School of Engineering, Taylor's University.
