Improper disposal of municipal organic waste represents an environmentally sustainable development front barrier, thus being the search for solutions and alternatives aimed at reusing stand out as an integrated management and waste management, mainly from the institution of the National Policy Solid Waste, through Law Number 12.305 of August 2, 2010. Accordingly, the present study was conducted to collect and characterize the waste from the municipality of Pirangi, SP sewage treatment plant, as well as those originating from the grinding of pruning trees, with a view to biostabilization through composting and reuse for the development of alternative substrates on the germination and early development of Croton urucurana Baill. The experiment was conducted at the Department of Rural Engineering FCAV/UNESP, Jaboticabal, SP, as well as the municipal nursery Pirangi. From the collection, characterization and analysis of waste, these were submitted to the composting process, which was inserted 50% sewage sludge and 50% crushed pruning (bulking agent). After obtaining compound, has been subjected to the following treatments: T1-100% steep bank with mineral fertilizer (100% TBAM); T2-100% steep bank without fertilization (100% TBSA); T3-25% organic compost + 75% of steep bank (25% CO); T4-50% organic compost + 50% steep bank (50% CO); T5-75% organic compost + 25% steep bank (75% CO) and T6-100% organic compound (100% CO). The experimental design was randomized blocks, factorial with 6 substrates, 3 water levels (50, 100 and 150% evapotranspiration) and 3 replications.From sowing, evaluations of emergency were held, and at 150 days, there was a shoot height, stem diameter, number of leaves, length of taproot, the fresh mass (air, root and total) and dry matter (air, root and total). Among the results it was found that the sewage sludge collected at ETE Pirangi presents agronomic potential, since it fits in CONAMA Resolution Number 357/2005. For ...
