Abstract

Life cycle assessments addressing municipal solid waste management systems (MSWMS) most often represent and evaluate these systems or compare isolated technological and management solutions in a much too simplistic interaction with their surroundings, accounting for a minimum of probable future system interactions/effects and using static representations of background systems (e.g. the use of simple marginals or average when modelling energy from waste integration in the energy system). The nature of the background systems is known to be especially decisive when comparing the global warming potential (GWP) of different waste management strategies.
Within the study reported here, a number of alternative MSWMS were simulated and evaluated, comprising combinations of separate collection and different downstream treatment/handling approaches for remaining residual waste, including advanced mechanical treatment with additional material recovery as an alternative to direct thermal treatment. These systems represent strategies considered by a number of Danish regional authorities to meet targets, while maintaining or enhancing the benefits of energy recovery. The simulated systems were assessed and compared against a large variety of background system scenarios, consisting of the most probable future development of the Danish energy system (and surrounding countries) towards 2050.
Specific focus was placed on identification and modelling of possible indirect effects on adjoining systems that would result as consequence of implementation of such alternative systems, including: 1) synergy between biowaste separate collection and animal manure utilization for biogas production; 2) liberated incineration capacity due to increased separate collection leading to combustible waste imports and possible avoided landfilling; and 3) production of local refuse derived fuel (RDF) increasing flexibility with waste-derived energy integration.
Results showed that in short-to-medium term, MSW management would see a decrease in GHG savings, consistent with the diminishing share of fossil fuels in the energy system being displaced by the energy recovered from the waste. The ability to maintain net waste-derived GHG savings from waste energy recovery in a longer-term perspective was found to be potentially dependent on the ability to integrate waste based energy production in the surrounding energy system. From a climate perspective, the benefits of recycling gain more prominence in in the future.
