                An important consideration when designing the transfer station is to take
                into account the method of energy used and capital investment such as auto-
                matic sorting, manual sorting, magnetic separator, etc.
                     Recycling is the first process to be considered for solid waste manage-
                ment. The process of recycling is used to recover and reuse materials from
                spent products. That is why recycling is used to recover as much as possible
