Popis: The physicochemical characteristics of paper sludge from the paper industry allow its use in composting for agricultural purposes, becoming a sustainable disposal alternative for this type of waste. The aim of this article is, to define the levels of treatment that allow obtaining compost with recommended percentages of Carbon and Nitrogen for agricultural use, through a design of experiments (DOE). The proportion of paper sludge in the mixture (50% and 75%) and the composting technique (composting and vermicomposting) were defined as experimental factors. It was concluded that the vermicomposting method, accompanied by a high proportion of paper sludge, allows obtaining compost with adequate levels for response variables: % C and % N.
