The privatization effect of MSW incineration services by using data envelopment analysis

This paper attempts to compare the relative efficiency across MSW incineration facilities under the three operating modes including government-owned government-operated (GOO), government-owned private-operated (GOPO), and private-owned private-operated (POPO) by using the Data Envelopment Analysis (DEA), and to examine the factor in affecting the efficiency variation. The results show that technical efficiency scores are 0.7538, 0.9046 and 0.9917 for GOO, GOPO and POPO, respectively. An ANOVA is conducted and the analysis result confirms that the operating mode has significant impact on technical efficiencies. A further examination on the operating contracts signed between governments and operating firms of GOPO facilities finds that both the price protection and quantity protection also play vital roles in affecting efficiencies.     

An LCA model for waste incineration enhanced with new technologies for metal recovery and application to the case of Switzerland

A process model of municipal solid waste incinerators (MSWIs) and new technologies for metal recovery from combustion residues was developed. The environmental impact is modeled as a function of waste composition as well as waste treatment and material recovery technologies. The model includes combustion with a grate incinerator, several flue gas treatment technologies, electricity and steam production from waste heat recovery, metal recovery from slag and fly ash, and landfilling of residues and can be tailored to specific plants and sites (software tools can be downloaded free of charge). Application of the model to Switzerland shows that the treatment of one tonne of municipal solid waste results on average in 425 kg CO₂-eq. generated in the incineration process, and 54 kg CO₂-eq. accrue in upstream processes such as waste transport and the production of operating materials. Downstream processes, i.e. residue disposal, generates 5 kg CO₂-eq. Savings from energy recovery are in the range of 67 to 752 kg CO₂-eq. depending on the assumptions regarding the substituted energy production, while the recovery of metals from slag and fly ash currently results in a net saving of approximately 35 kg CO₂-eq. A similar impact pattern is observed when assessing the MSWI model for aggregated environmental impacts (ReCiPe) and for non-renewable resource consumption (cumulative exergy demand), except that direct emissions have less and no relevance, respectively, on the total score. The study illustrates that MSWI plants can be an important element of industrial ecology as they provide waste disposal services and can help to close material and energetic cycles.
