A Concept for the Environmental Evaluation of Waste Management Benefits

摘要: Abstract For the removal of a certain waste stream in general several options are available. According to common applied ‘stair concept’ prevention should be first option. If this is not possible re-used and otherwise it incinerated or landfilled. Though valuable rule thumb, scientific public discussions show that approach can quite few cases too rough make accepted decisions. This paper presents more sophisticated approach, called Waste management benefit concept. It has been developed on basis methodologies used Environmental Impact Assessment, (health) risk analysis product Life Cycle Analysis. A system-approach presented, which all relevant environmental effects related whole life-cycle process analyzed aggregated an integrated judgement. The methodology tested case polluted sediments. Four have compared: (1) no removal, (2) covering sediment with isolating clay layer, (3) dredging landfill (4) sintering sewage sludge so-called ‘eco-gravel’. Apart from theme ‘acidification’ re-use alternative shows most friendly case-study shown principle suitable perform quantitative, integral transparent comparison benefits options.
