Environmental Impact and Circularity of Plastic Film Scrap Recovery and Valorization

open access: yesAdvanced Sustainable Systems, Volume 10, Issue 4, April 2026.
Life cycle assessment and circularity indicators are jointly applied to a real industrial case of plastic scrap recovery in polypropylene film production. Different allocation methodologies are compared to highlight how modeling choices can affect environmental impacts and circularity outcomes.

Numerical Modeling and Performance Evaluation of a Three‐Stage Direct–Indirect–Direct Evaporative Cooler

open access: yesEngineering Reports, Volume 8, Issue 4, April 2026.
A three‐stage direct–indirect–direct evaporative cooling system is numerically modeled and evaluated under various climatic conditions. Results show significantly higher cooling effectiveness and temperature reduction compared to conventional single‐stage coolers, demonstrating the system's potential as a sustainable and energy‐efficient solution for ...

Meta-heuristic algorithms in car engine design: a literature survey [PDF]

open access: yes, 2015
Meta-heuristic algorithms are often inspired by natural phenomena, including the evolution of species in Darwinian natural selection theory, ant behaviors in biology, flock behaviors of some birds, and annealing in metallurgy.

A rural agricultural-sustainable energy community model and its application to Felton Valley, Australia [PDF]

open access: yes, 2013
Energy and food security require a delicate balance which should not threaten or undermine community prosperity. Where it is proposed to derive energy from conventional fossil fuel resources (such as coal, shale oil, natural gas, coal seam gas) located ...

Advanced exergy analysis of a R744 booster refrigeration system with parallel compression [PDF]

open access: yes, 2016
In this paper, the advanced exergy analysis was applied to a R744 booster refrigeration system with parallel compression taking into account the design external temperatures of 25 C and 35 C, as well as the operating conditions of a conventional European

MaimAir: A flexible and modular energy storage system for tomorrow energy banks [PDF]

open access: yes, 2016
We considered a novel energy storage system based on the compression of air through pumped water. Differently from CAES on trial, the proposed indirect compression leaves the opportunity to choose the kind of compression from adiabatic to isothermal. The

Ecosystem exploitation, sustainability and biodiversity: Are they compatible? [PDF]

open access: yes, 1994
This articles offers a basis for describing sustainability and then seeks to place this concept on an energetic basis by reference to recent advances in the understanding of patterns and processes in (mainly pelagic) fresh waters.
