Reclamation of sewage sludge for use in Israeli agriculture: economic, environmental and organizational aspects

This paper develops a regional-level planning model aimed at allocating treated sewage sludge among potential users. The model incorporates, in one endogenous system, the economic, biological and environmental relationships and its objective is to maximize the regional social welfare. A few allocation approaches from the concept of transferable utility games are applied to determine a reasonable and fair allocation of the additional net benefits resulting from regional co-operation which is acceptable to all relevant economic units (players). The analysis is applied to a region in Israel and the results support regional collaboration among the relevant players which increase economic benefits by 19% and enable avoidance of sea pollution.
