Resum: The objective of this study was the application of the experimental design technique to optimize the conditions for the bioremediation of contaminated soil by means of composting. A low-cost material such as compost from the Organic Fraction of Municipal Solid Waste as amendment and pyrene as model pollutant were used. The effect of three factors was considered: pollutant concentration (0. 1–2 g/kg), soil:compost mixing ratio (1:0. 5–1:2 w/w) and compost stability measured as respiration index (0. 78, 2. 69 and 4. 52 mg O2 g⁻¹ Organic Matter h⁻¹). Stable compost permitted to achieve an almost complete degradation of pyrene in a short time (10 days). Results indicated that compost stability is a key parameter to optimize PAHs biodegradation. A factor analysis indicated that the optimal conditions for bioremediation after 10, 20 and 30 days of process were (1. 4, 0. 78, 1:1. 4), (1. 4, 2. 18. 1:1. 3) and (1. 3, 2. 18, 1:1. 3) for concentration (g/kg), compost stability (mg O₂ g−1 Organic Matter h−1) and soil:compost mixing ratio, respectively.
