Abstract: Slow and fast pyrolysis of sludge and sludge/disposal filter cake (FC) mix are performed to investigate the liquid and solid products for their use as value added products. The obtained slow pyrolysis liquid products separate in an oil, a water rich fraction and a valuable crystalline solid 5,5-dimethyl hydantoin. During fast pyrolysis, mainly an oil fraction is formed. Aliphatic acids and amides present in the water rich fractions can be considered as value added products and could be purified. The oil fractions have properties which make them promising as fuel (25-35 MJ/kg, 14-20 wt% water content, 0.2-0.6 O/C value), but upgrading is necessary. Sludge/FC oils have a lower calorific value, due to evaporation of alcohols present in FC. ICP-AES analyses reveal that almost none of the metals present in sludge or sludge/FC are transferred towards the liquid fractions. The metals are enriched in the solid fractions.
