The hurdles of local governments with PPP contracts in the waste sector

With this paper we identify a number of the theoretical principles that apply to public-private partnership (PPP) contracts, introducing new case studies and policy discussions relevant for Europe and elsewhere. We discuss to what extent these contracts can and should be applied in the waste sector and perform a comparison between the purely contractual and the institutionalised models of PPP arrangements. We analyse four case studies in the 'wholesale' waste market in Portugal and examine the implementation and degree of success of these partnerships in the field. It seems that public authorities are failing to secure an adequate level of protection of the public interest. Drawing on the empirical evidence, we present some guidelines that could lead to better regulatory contracts for waste services.
