Assessment of the effectiveness and efficiency of packaging waste EPR schemes in Europe.

This paper provides an analysis of the performance of European packaging waste systems, focusing on Extended Producer Responsibility schemes and Producer Responsibility Organizations. We adopt two separate but complementary empirical analysis: i) an indicator-based assessment of the cost-efficiency and recycling effectiveness of PROs; ii) a regression analysis of the determinants of recycling rates at the national level. The analysis spans over 25 national schemes and 21 Producer Responsibility Organizations. Our findings show that systems that have higher recycling rates do not entail necessarily higher costs. Non-competitive systems are more successful in increasing recycling rates no matter the cost; moreover, they are better able to use funds collected from EPR fees charged to producers, delivering improved cost-efficiency. Furthermore, higher recycling rates are associated with systems in which local authorities retain the operational responsibility of collection. Systems that do not involve local authorities always underperform. The policy implications are clear: local authorities should have some responsibility for collecting and sorting packaging waste and competitive systems should not be looked at as a first choice when designing a national recycling strategy. A mix of policy schemes, including non-profit EPR, door-to-door collection and Deposit-Refund-Schemes can be effective strategies for increasing the recycling rates of the waste streams that need more intervention, most notably plastic packaging.

The relationship between air pollution and diabetes: A study on the municipalities of the Metropolitan City of Milan.

AIMS: Urbanisation has been linked with an increased risk of developing diabetes mellitus, dramatically worsening the healthcare system's financial burden. Environmental influences are emerging among the causing factors of the urban diabetes epidemic. We evaluated the relationship between air pollution and the prevalence of diabetes in the Municipalities of the Metropolitan City of Milan, comprising more than 3,4 million citizens. METHODS: The prevalence of diabetes in the resident population and the mean annual air concentrations of PM10 and NO2 were retrieved from the municipal Agency for Health Protection and the regional Agency for Ambient Protection datasets. Two linear regression models were estimated to inspect the relationships between the (logit-based transformed) diabetes prevalence and air pollution concentrations, namely: (i) PM10, and (ii) NO2. Both models were adjusted for five control variables, including the qualitative variable year (2011-2018). RESULTS: Both models highlight a statistically significant positive relationship between air pollutants and diabetes prevalence. An increase of one PM10 or NO2 concentrations' unit translates into a rise of 0.81% or 0.41% in diabetes prevalence, respectively. CONCLUSION: Our results contribute to the ongoing research regarding health outcomes of urbanisation dynamics and should be considered in city planning policies.
