Though zero emission is recognized as the only and best solution for waste management with sustainability, it seems to be impossible to achieve it under current technical and social circumstances. In this paper, net cost of the emission management, which includes recycling, cascading, and disposing, was derived. Minimizing it with the constraint of the capacity of the final disposal site, the optimal portfolio of the emission management methods was dynamically derived. The problem was formulated as a nonlinear programming problem and solved with the software GAMS/MINOS. With this optimization, following two conclusions were acquired. Firstly, if the society has only two options of recycling and disposing, recycling rates must increase as final disposal site depletes. Secondly, in order to avoid this increase of the responsibility of recycling, cascading, which releases the society from the constraint of the capacity of the final disposal site, must be introduced.
