Special Issue Information

Dear Colleagues,

Life Cycle Assessment (LCA) has become a crucial methodological framework for evaluating the environmental performance of technologies, processes, and systems across all stages of their life cycle. In the energy and industrial sectors, which are some of the major contributors to global environmental impacts, LCA provides essential insights to guide sustainable innovation and reduce resource consumption, emissions, and waste. This Special Issue invites original research, case studies, and methodological contributions that demonstrate the application of LCA in supporting the transition of energy production systems (including renewables, fossil fuels, and hybrid solutions) and industrial operations (such as manufacturing, materials processing, and infrastructure) towards the sustainable development goals. Studies addressing comparative assessments, sector-specific benchmarks, eco-design strategies, and the integration of LCA into policy or industrial decision making are particularly welcome. The objective is to highlight the role of LCA in advancing cleaner technologies, improving industrial efficiency, and fostering sustainability-driven transformation across critical sectors.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Clean Technologies is an international peer-reviewed open access semimonthly journal published by MDPI.

The growing demand for acrylic acid, driven by its widespread use in polymers and specialty chemicals, raises concerns regarding the environmental impact of its conventional fossil-based production. In this context, the present study evaluates the techno-environmental performance of a glycerol-based acrylic acid route compared to the conventional propylene pathway. Process simulations were carried out using CHEMCAD for an annual capacity of 50,000 tons. The environmental impact is assessed through Life Cycle Assessment (LCA) methodology and LCA for Experts software, following the ReCiPe 2016 (H) impact method. The results show that the glycerol-based route requires higher raw material input (1.90 kg/kg acrylic acid) than the propylene pathway (0.84 kg/kg acrylic acid), yet generates slightly lower liquid wastes (3.25 kg/kg acrylic acid vs. 3.60 kg/kg acrylic acid). From an environmental standpoint, the glycerol route performs better in 12 of 16 impact categories. The conventional process is dominated by the propylene supply chain, contributing up to 62% of the global warming impact, while electricity demand ranks second in the glycerol-based route. Scenario analysis based on future European electricity mixes (EU-2030 and EU-2050) further reduces climate and fossil depletion impacts, although with increased mineral resource use. Overall, the results highlight the potential of glycerol as an alternative feedstock and the key role of electricity sourcing. Full article
