Separate waste collection in mountain municipalities. A case study in Campania

This paper aims to analyse the impact of land characteristics (i.e. altimetry and housing dispersion) on separate waste collection, with a focus on mountain municipalities. The high spatial heterogeneity of the driving factors of separate waste collection allows traditional techniques, such as OLS, to offer only a partial depiction of the situation, missing important information. In this view, we perform the Geographically Weighted Regression (GWR), which allows to control for the local determinants of waste management. Our data cover 550 municipalities of Campania, in Southern Italy. We control for a set of morphological and socio-economic variables, drawn from official records for 2012. Our results show that the relationships between land characteristics and separate waste collection are not constant over space. Moreover, they suggest that in the presence of non-modifiable factors (such as land characteristics) local governments should act on citizen motivations, promoting awareness on environmental issues, and should implement time-saving collection methods.

石油化工中絮凝过滤污水处理的应用研究

含油污水具有成分复杂，量大面广，含油量高，水质差别大，处理过程复杂等特点。采用凝絮一吸附一过滤复合方法，选择合适的污水处理工艺，对含油污水进行处理回用，现场试验处理后的水质可以达到回用要求。且凝絮一吸附一过滤方法工艺简单，成本低廉，可以达到改善环境，降低成本的良好效果，是具有应用和推广前途的含油污水处理方法。     

Food waste paradox: antecedents of food disposal in low income households

This article aims to identify antecedents of food waste among lower‐middle class families – a paradox, given the financial constraints this population faces. The importance of this research is evident in escalating environmental pressures for better use of our planet's scarce resources. Given that most of the world is low‐income, any behavioral change in this population is likely to have a considerable impact. Empirical data were collected from 14 lower‐middle income Brazilian households, based on observations, in‐depth interviews, photographs and a focus group (n = 6). Five major categories of food waste antecedents were identified: (1) excessive purchasing, (2) over‐preparation, (3) caring for a pet, (4) avoidance of leftovers and (5) inappropriate food conservation. Several subcategories were also found, including impulse buying, lack of planning and preference for large packages. Surprisingly, findings show that strategies used to save money – such as buying groceries in bulk, monthly shopping trips, preference for supermarkets and cooking from scratch – actually end up generating more food waste. This mitigates the savings made during the purchasing phase.
