文摘
Lack of regulations and standards on mineral waste recycling makes Life Cycle Assessment (LCA) and Ecological Risk Assessment (ERA) useful methods for environmental assessment of recycling scenarios. An unsolved problem arises whenever two scenarios of recycling have to be compared according to both ERA and LCA impact results considered simultaneously. A methodology to combine LCA and ERA results and tools toward Integrated Environmental Assessment (IEA) is proposed together with three application examples based on case studies.
The most effective combination approach is to define further impact categories for ERA to be considered with the standard LCA ones. Then, the use of a multicriteria analysis method was proved to be an efficient way to rank alternative scenarios with respect to all the results. The key issues to be further researched are discussed and proposals are suggested.
