A theoretical model is presented in order to study the optimal combination of natural resources, used as inputs, taking into account their natural growth ability and the technical possibilities of input substitution. The model enables us to consider renewable resources, nonrenewable, or both....

This article focuses on the technological aspect of recycling, its effect on the production set of the economy and the optimal use and substitution of natural resources in production. We provide a framework that enables us to compare the relevance of using renewable resources and recyclable...

We study the optimal capacity of landfills taking into account their sequential nature. Such an optimal capacity is characterized by the so-called Optimal Capacity Condition. Particular versions of this condition are obtained for two alternative settings: first, if all the landfills are to have...
