Integration of life cycle assessment and system dynamics modeling for environmental scenario analysis: A systematic review.

System dynamics (SD) is widely recognized as a tool for simulating spatial and temporal dynamics in life cycle assessment (LCA) studies of the product system. However, there is no agreement on how SD and LCA could be applied effectively together in a consistent way. To address this gap, this research conducted a systematic literature review, analyzing 54 scientific articles published worldwide between 2010 and 2023, to explore the joint application of LCA with SD.

A life cycle assessment approach for nitrogen footprint quantification: the reactive nitrogen indicator.

Among the environmental issues that have recently catalyzed the attention of the scientific world, we must undoubtedly include the perturbation in the biogeochemical flows of nitrogen and phosphorus, which have been identified as one of the major risks on a global scale, also considering its social implications, since the use of macronutrients is essential to guarantee the food needs of the world population. In this context, there is a growing interest in the evaluation of the environmental impact related to this issue, particularly with regard to the effects of changes in the nitrogen cycle and the methods for quantifying them. In the latter field, several researches have recently been developed focusing on the indicator known as the nitrogen footprint, associated with the environmental releases of reactive nitrogen.

Combination of product environmental footprint method and eco-design process according to ISO 14006: The case of an Italian vinery.

To support the sustainable development of the primary sector, in line with green new deals emerging worldwide, eco-design of new agri-food products is a priority. The wine industry, due to its growing market, has matured the need to develop an approach for understanding the environmental impacts of its products and to develop strategies to reduce such impacts in a life cycle perspective. This study has a two-fold aim: presenting the development of a methodological proposal for the use of PEF and PEF-CR in the eco-design of wine products; testing its applicability in a case study in the wine sector.

Theoretical analysis of fluorine addition to single-walled carbon nanotubes: functionalization routes and addition patterns.

We present a theoretical investigation on the chemical addition patterns governing the fluorination of single wall carbon nanotubes. Monte Carlo calculations based on a Hückel model suggest that fluorination is stabilized in a bandlike pattern due to electronic confinement effects on the tube bond network topology. Ab initio analysis of the fluorination of small nanotubes show that fluorine addition along the nanotube axis direction is favored by a mechanism of carbon framework distortion.
