Taking this perspective, our study adopts an exploratory research design to discover the pragmatic implications emerging from a case study. The City of Turin joined proGIreg, a European project that entails the regeneration of former industrial districts by means of nature-based solutions (NBS). Ranging from aquaponics to green roofs, seven NBS have been experimented in Turin, which rely on the use of natural systems to tackle social, economic and environmental challenges efficiently and sustainably. Among them, the most promising is related to the production and test of the ‘new soil’, a blend obtained by mixing earth materials coming from construction sites with compost, zeolites and mycorrhizae.

(2-Acetoxy)allyl nitro compounds have been prepared for the first time in a four-step procedure by a preliminary reaction of nitroalkanes with 2-(phenylselenyl)acetaldehyde. After the acetylation of the obtained nitro alcohols, the unsaturation is installed by an oxidation reaction involving the phenylselenyl group followed by a thermal elimination. The oxidation process is accomplished under flow conditions ensuring a notable lowering of overoxidation by products observed in batch.

In this context, plastic plays a pivotal role, because its accumulation and persistence is becoming a matter of great concern. In 2017, 43% of plastic packaging is recycled.. In order to understand the barriers and the criticisms which hamper the development of a more efficient recycling pathway for plastics, one of the most important material recovery plants of Turin has been selected as case of study. The plants belongs to Amiat, the multi-utility working in waste collection on the behalf of Turin Municipality. This plant can treat up to 66 ktons/year of plastic packaging. Its function is to pre-select the materials coming from the separate collection, in order to guarantee the necessary level of quality to allow the recycling process. In fact, pre-selection is required for different reasons: a non-efficient separation performed by the citizen, as well as administrative and legal constraints on plastics treatment, such as recycling plastic packaging only. Hence, this work is willing to identify the key-actors involved in the plastic recycling process as well as to analyse the role of the selected plant using a case study methodology, assessing the key barriers and suggesting possible solutions for future scenarios of plastics recycling.
