Resource or waste? A perspective of plastics degradation in soil with a focus on end-of-life options.
2018
‘Capable-of-being-shaped’ synthetic compounds are prevailing today over horn, bone, leather, wood, stone, metal, glass, or ceramic in products that were previously left to natural materials. Plastic is, in fact, economical, simple, adaptable, and waterproof. Also, it is durable and resilient to natural degradation (although microbial species capable of degrading plastics do exist). In becoming a waste, plastic accumulation adversely affects ecosystems. The majority of plastic debris pollutes waters, accumulating in oceans. And, the behaviour and the quantity of plastic, which has become waste, are rather well documented in the water, in fact. This review collects existing information on pla…

Las bodegas cooperativas y la comercialización del vino en España durante el siglo XX
2020
Resumen Las bodegas cooperativas surgieron con un doble objetivo: la elaboracion en comun del vino, para reducir los costes de produccion y aumentar la calidad del producto; y la venta en comun del vino, con una reduccion de los intermediarios y una mejora de la posicion de los viticultores en el proceso de comercializacion. Ambos objetivos tenian que suponer una mayor remuneracion del producto y, en consecuencia, del ingreso de los productores, que en el sector vitivinicola eran fundamentalmente pequenos agricultores familiares, enfrentados a un contexto de caida tendencial de los precios del vino. En este articulo realizamos una primera aproximacion al papel de las bodegas cooperativas en…
Mines and quarries production: A driver analysis of withdrawals in Italy
2020
Abstract The growing demand for non-energy mineral resources has determined relevant withdrawals as well as import-export flows. This paper aims to disentangle the drivers of raw non-energy mineral resources extraction in Italy. Using a new dataset of raw resources extracted from mines and quarries in the 21 Italian regions (19 regions and 2 autonomous provinces of Trento and Bolzano) for the period 2013–2016, our empirical analysis confirms the relevance of mining and quarrying producer price index as well as the manufacturing and construction sectors as main drivers. In line with the Hotelling (1931)'s theory, a positive relationship between m&q mineral resources extraction intensity and …
POEMS: A Case Study of an Italian Wine-Producing Firm
2006
Over the last decade, researchers paid much attention to concepts such as Design for Environment, Extended Producer Responsibility, Responsible Chain Management, and Eco-design. Many management tools and standards (such as EMAS, ISO 14001, LCA, EPD, Ecolabel) have been developed to support companies in the evaluation and management of their environmental performance and to pursue continual environmental improvement. The more recent development of the aforesaid fields looks at interorganizational environmental management. Such an approach can complement the more traditional intraorganizational corporate environmental management approaches and tools. A typical example of this new trend is the…
Fundamentals of photocatalysis: The role of the photocatalysts in heterogeneous photo-assisted reactions
2021
Abstract This chapter provides some general definitions of heterogeneous photocatalysis and evaluates its performance, which is influenced by the parameters most closely related to the properties of the solid material that acts as a photocatalyst. It also discusses aspects of heterogeneous photocatalytic reactions and explains the properties that influence photoactivity. Finally, the chapter examines thermodynamic and kinetic features, including mechanistic details and parameters to define the reaction rate and correlates them to the effects of the interaction of light with the photocatalyst surface and adsorption-desorption of species involved in heterogeneous photo-assisted reactions.
Environmental performance of wood pellets' production through life cycle analysis
2016
Abstract Forests play a key role as the source of an essential renewable material and/or fuel: wood. The aim of this study was to evaluate the environmental impacts related to high-quality pellet production for domestic heating following the LCA (life cycle assessment) methodology and considering a cradle-to-gate perspective in the Tuscany region. This is representative and interesting for Italian pellet factories and for similar factories located in Central Europe, considering the Italian contribution to the production capacity of that area. All of the activities involved, from wood extraction in no-industrial forests to packed pellet production, ready for delivery to final users, were tak…
Dependence between renewable energy related critical metal futures and producer equity markets across varying market conditions
2022
We study the dependence of renewable energy production-related critical metal futures and producer equity returns, compared to the non-renewable energy (oil and natural gas) and some other globally relevant commodity markets. We find different asymmetric and symmetric dependencies in these commodity markets. The dependence is asymmetric in the most important critical metal markets, i.e., of silver, copper, and platinum. Still, surprisingly, for example, in the oil market, the relationship is symmetric, and no relationship is found in the natural gas market. Furthermore, the oil and agricultural markets have homogenous dependence structures in most market conditions, so the information trans…
