Waste input-output linear programming model with its application to eco-efficiency analysis

This paper is concerned with a decision analytic extension of the waste input-output model, based on the method of linear programming. The resulting model, which is named the waste input-output linear programming model, allows one to automatically obtain an 'optimal' waste management and recycling strategy from among a given set of alternative feasible strategies. The model can thus explore the extent to which a given measure of eco-efficiency can be maximized by an appropriate combination of existing (technological and resource) potentials. An application to Japanese data is also presented.
