Reconciling human health with the environment while struggling against the COVID-19 pandemic through improved face mask eco-design.

Surgical masks have become critical for protecting human health against the COVID-19 pandemic, even though their environmental burden is a matter of ongoing debate. This study aimed at shedding light on the environmental impacts of single-use (i.e., MD-Type I) versus reusable (i.e., MD-Type IIR) face masks via a comparative life cycle assessment with a cradle-to-grave system boundary. We adopted a two-level analysis using the ReCiPe (H) method, considering both midpoint and endpoint categories. The results showed that reusable face masks created fewer impacts for most midpoint categories. At the endpoint level, reusable face masks were superior to single-use masks, producing scores of 16.16 and 84.20 MPt, respectively. The main environmental impacts of single-use masks were linked to raw material consumption, energy requirements and waste disposal, while the use phase and raw material consumption made the most significant contribution for reusable type. However, our results showed that lower environmental impacts of reusable face masks strongly depend on the use phase since reusable face masks lost their superior performance when the hand wash scenario was tested. Improvement of mask eco-design emerged as another key factor such as using more sustainable raw materials and designing better waste disposal scenarios could significantly lower the environmental impacts.

Survey data for assessing the socio-economic performance of End of Life options of a bio-based product based on expert knowledge.

This data article aims at providing a data description about the manuscript entitled "A socio-economic indicator for EoL strategies for bio-based products" [1]. Data regarding the socio-economic assessment of End of Life (EoL) options for the specific case of PLA-based film for food packaging are presented, with a special emphasis on policy recommendations and actions for the EoL practices in the bioeconomy sectors. A new framework, based on data gathering and validation through experts involvement, is proposed in order to calculate a new indicator to measure the socio-economic performance of EoL practices (SEI-EoL) for bio-based products. Experts were identified from the Horizon 2020 LIFE-funded projects and/or Scopus databases. Two rounds of survey were carried out to determine the weights of socio-economic criteria for bio-based products and the values for the selected case study. The aggregation of these data enabled us to obtain a final ranking of different EoL alternatives. Finally, a third round of survey was conducted to further deepen our understanding of actions and recommendations needed to improve EoL practices in bio-based sectors. Resulting data have a mix of quantitative and qualitative characterization. A potential reuse of these data can allow future estimations, empirical analyses or a direct comparison with the use of experimental observations.

The transition towards a bio-based economy: A comparative study based on social network analysis.

This paper focuses on the development of a bioplastics innovation niche as an important sector of the bio-based economy and a viable solution to promote sustainable long-term growth. Relying on the Strategic Niche Management framework, the following niche mechanisms are analysed: (1) convergence of expectations, (2) learning processes, and (3) networking with powerful actors in the sector. We conducted a comparative analysis, looking at Italy and Germany, two frontrunner countries in the bioplastic production who have enacted divergent policies in support of this sector. The comparative perspective has brought some interesting insights into the maturity level of the two respective niches, as well as into the emerging architectural properties of the underling social networks. Core findings show a general high level of expectations in the bioplastics sector in both countries, whereas key elements undermining the niche development refer either to the lack of policy support or to the changing and unstable institutional and regulatory framework. Regarding the architectural structure, the Italian network of actors was largely characterized by an active exchange of knowledge among firms, whereas the German network was characterized by the presence of several institutional actors actively participating in knowledge flows. This last result relates, in the authors' view, to the different policy strategies followed by national governments in the two countries: the German case being characterized by large public investment in R&D, whereas the Italian case is mostly characterized by demand side policies that effectively created a market for bioplastic shoppers.
