Organic waste represents an opportunity and a challenge for policy decision makers and lately the attention has been focusing on community composting practices identifying the environmental and/or economic aspects. Evidence of citizens’ attitudes and preferences is scarce, and this paper aims to fill this gap. The results of a contingent valuation survey in three councils of the Province of Siena, Tuscany (Italy) are reported along with an extended cost-benefit analysis. Results echo previous findings that GHGs emissions and money-saving for all municipalities are positive and encouraging; moreover, our study proves that citizens are keen to switch to the community recycling composter system. Citizens present heterogeneous preferences and accordingly to the current waste management system they might need a small financial compensation to switch in favour of the local community system.
