The final disposal of solid wastes is a serious environmental problem, mainly in big towns, where the areas to put the refuses on are not much available. To provide one more alternative to solve this problem, a research was developed to analyse the vermicomposting of industrial sludge combined with a compost of municipal solid refuse. By this process, it was possible to obtain the recycling of the wastes, producing a material called humus or vermicompost. The results showed good maturity levels of the refuses, presented by the carbon/nitrogen relations, the worms influence in the pH elevation and their possible acceleration of the organic material stabilization.
