Toward Sustainable PLA-Based Multilayer Complexes with Improved Barrier Properties

2019

Poly(lactic acid) or PLA is currently considered as one of the most promising substitutes of conventional plastics, with low environmental impact, especially for food packaging applications. Nevertheless, some drawbacks, such as high permeability to oxygen, are still limiting its industrial applications. The objective of this study was to highly increase the oxygen barrier performance of PLA without compromising its sustainable nature and following the principles of circular economy perspective. Coproducts coming from mill industries, such as wheat gluten proteins (WG), were used to produce PLA-WG-PLA multilayer complexes with improved barrier performance. Different technologies of industri…

La prise en compte de la durabilité dans les stratégies marketing des PME : apports et limites

2011

Nous examinons dans cet article comment des directeurs de PME agroalimentaires à fort ancrage territorial s’approprient la notion de développement durable et l’expriment dans leurs stratégies marketing. Nous examinons successivement leur vision du lien entre développement durable et performance, l’impact des caractéristiques environnementales sur leurs pratiques et les limites qu’ils perçoivent à cette volonté d’intégrer la durabilité dans leur stratégie au moment de sa mise en œuvre. Au-delà de l’argument commercial, la durabilité apparaît comme un levier intéressant du projet d’entreprise et de la mobilisation des salariés. Néanmoins, la démarche comporte aussi des limites.

The implementation of new special education legislation in Finland

2014

This article examines the implementation of new special education legislation in Finland among students with significant disabilities. The data consist of a nationwide survey and field observations. In the analysis, a policy implementation framework is utilized as a theoretical lens. The findings suggest that schools and municipalities that had participated in long-term development projects had more capacity and willingness to reform special education practices substantially, suggesting that learning in one policy area can transfer to other domains across multiple levels of national and local governments. The key findings highlight the significance of professional trust as a policy instrum…

Impact of Separator Thickness on Temperature Distribution in Single Cell of Polymer Electrolyte Fuel Cell Operated at Higher Temperature of 90 °C and…

2022

The New Energy and Industry Technology Development Organization (NEDO) road map (Japan, 2017) has proposed that a polymer electrolyte fuel cell (PEFC) system, which operates at a temperature of 90 °C and 100 °C, be applied for stationary and mobility usage, respectively. This study suggests using a thin polymer electrolyte membrane (PEM) and a thin gas diffusion layer (GDL), at the same time, to achieve better power-generation performance, at a higher temperature than usual. The focus of this paper is to clarify the effect of separator thickness on the distribution of temperature at the reaction surface (Treact), with the relative humidity (RH) of the supply gasses and initial operation tem…

A Power Law Behavior in the Incentivized Italian Photovoltaic Market

2018

The Italian photovoltaic (PV) marketis analyzed by using the data contained in the database that describes all PV Plants installed in Italy under the incentive program called “2nd Conto Energia”. It is shown that the cumulative probability distribution of the size of the installed PV plants has a broken power tail. An approach to partially quantify the effect of the economic, juridical and technical rules is introduced in order to show how the regulatory body influences the power tail of the cumulative probability curve.

Economic Sustainability of Italian Greenhouse Cherry Tomato

2014

Greenhouse tomato cultivation plays an important role in Sicily, being the primary production area in Italy, due to its favorable pedo-climatic conditions that permit extra-seasonal productions. In Sicily, more than half of greenhouse tomato production is derived from the Province of Ragusa on the southeastern coast, where especially cherry tomato typologies are cultivated. Over the last decade, the Ragusa Province has registered a decrease both in terms of greenhouse tomato area and harvested production due to several structural problems that would require restructuring of the tomato supply chain. Thus, since recognition of real costs and profitability of tomato growing is a vital issue, b…

Peut-on concilier un faible usage de pesticides, une bonne performance économique et environnementale ? Analyse d’un réseau national de fermes de dém…

2017

Feeding an increasing world population with a sustainable agriculture is one of the greatest challenges of this century. The reduction of the reliance on pesticides is a critical aspect in this quest for sustainability. Whether cropping systems with reduced reliance on pesticides would be able to reconcile the various components of sustainability remains however a matter of debate. Are they as productive and profitable than current mainstream cropping systems? Here the objective is to study the feasibility of a reduced reliance on pesticides in France. We used a unique dataset from a national network of more than thousand arable commercial farms between 2009 and 2011. Launched in the framew…

Project into the Future. Introductory essay on the topic

2021

Investigating the Future is an established practice for the academy and the world of crafts and industry. From the Chicago Columbian Exhibition of 1893 to the two Worlds Fairs of New York City (1939 and 1965) and so on, the future has been foreseen as filled with technology and amazing architecture but not every vision of the future has described promising scenarios. The four visions of the future proposed by Norman Henchey (1978) conceptualized in classes – ‘possible’ (any future), ‘plausible’ (future that makes sense), ‘probable’ (highly likely to happen), ‘preferable’ (the best that could happen) – have been brilliantly described in the ‘Futures Cone’ reinterpreted by Joseph Voros (2003)…
