With the implementation of the NSWP (Law 12,305/10), the search for sustainable solutions for the management of organic solid waste was expanded, one of the environmentally and economically viable alternatives is vermicomposting. Our aim was to analyze a business plan for the implementation of a vermicompost production model in a Big bag system, originating from plant and animal waste. Big bag with 1,000 kg of capacity were used (reused chemical fertilizers bags). For the humus production, it was mixed: dry leaves (6.25%), tanned manure (72.13%), water (15.62%) and earthworms (Eisenia Foetida, 6%) from the rural property. These materials were stored in the Big bag, the entire transformation process into humus took place in 73 days, with a final production of 320 kg of humus / 0.542 m³ with a humidity of 47%. The system was composed of three Big bags that corresponded to a production module, and for this evaluation two modules were used, thus obtaining the final staggered production of 320 kg / month. Through financial indicators (ROI, TIR, NPV and Payback) it was possible to obtain a return of 60,68%, which was equivalent to R$ 667,44/month, it was found that the return on the initial investment is concluded in the third month in this business model, in addition to cash of R$ 261,25/month equivalent to ¼ of a minimum wage (R$ 1,045.00). It was found that the production of humus in Big bags + vermicomposting is viable for rural producers, for being a new income alternative and helps to reduce environmental impacts caused by the incorrect disposal of organic waste generated in rural properties.
