The paper gives information on the behaviour of a digester operating under semi-dry thermophilic conditions when algae are co-digested together with the organic fraction of municipal solid waste (OFMSW) at different ratios. These results are compared with those obtained digesting OFMSW alone at similar operative conditions. 25-30 % is the contribution that this approach can give to the disposal of harvested algae from the lagoon of Venice. Since after anaerobic digestion a bio-oxidative step is needed for agricultural utilization of digested sludge, this process has been studied and the performance of this step reported using the OFMSW as bulking agent.

Abstract
The paper gives information on the behaviour of a digester operating under semi-dry thermophilic conditions when algae are co-digested together with the organic fraction of municipal solid waste (OFMSW) at different ratios. These results are compared with those obtained digesting OFMSW alone at similar operative conditions. 25-30 % is the contribution that this approach can give to the disposal of harvested algae from the lagoon of Venice. Since after anaerobic digestion a bio-oxidative step is needed for agricultural utilization of digested sludge, this process has been studied and the performance of this step reported using the OFMSW as bulking agent.
