Atmospheric pressure air plasma treatment of water is a promising alternative to the industrially intensive Haber-Bosch process for the production of nitrogen fertilizer. Nitrogen fertilizer is vital for plant life, and the environmental impacts of modern fertilizer application cannot be neglected. In order to maintain or increase food production in the future, more sustainable alternatives must be investigated. Plasma can be easily operated at smaller scales, onsite, utilizing green energy sources, cutting down transportation costs and impacts. This article focuses on nitrogen fixation by plasma treating water for use as nitrogen fertilizer. We highlight recent advances (within the last two years) regarding water treating plasma devices, the challenges still facing the field, and recommend more thorough collaborative investigations be carried out in order to focus on the design and optimization of these devices for the future.

The chemical sector is integral to various industries but significantly contributes to environmental pollution and social impacts. Innovation is crucial in addressing challenges such as developing renewable energy storage materials, clean hydrogen production, and infinitely recyclable polymers. Additionally, the shift towards a sustainable chemical industry requires a skilled workforce proficient in sustainable and digital technologies. This paper explores the transition from linear production methods to a Circular Economy in the chemical industry through a literature review of recent publications (2022–2024). Six key papers have been identified that focus on the role of innovation and training in the green transition of the chemical sector. The findings highlight significant progress while outlining the remaining challenges in achieving a sustainable and environmentally friendly chemical industry.

Electricity-based chemical conversion is now recognized as a crucial technology for strengthening renewable energy in the pursuit of carbon neutrality. Atmospheric pressure plasmas have potential for nitrogen fixation when coupled with renewable energy, due to their ease of startup and shutdown, as well as their ability to adapt quickly to changing operating parameters. This short review highlights the plasma-based NOx formation, with a particular focus on advancements in NOx yield and energy cost over the past five years. Warm plasmas have demonstrated greater effectiveness than nonthermal plasmas in NOx production. Recent improvements in NOx yield and energy efficiency are discussed, along with a future outlook on their potential in power-to-X applications.

Sustainable development is one of the important concerns for organizational growth. Sustainability is described as “the ability to continuously maintain a process over time.” This concept includes the three kinds of dimensions in the aspects of society, economy, and environment. Life cycle sustainability assessment is a crucial tool for analyzing the sustainability of products, services, or processes, and it can help accelerate sustainable development. Life cycle sustainability assessment is the integrative analysis tool used to evaluate the impacts of society, economy, and environment of concerns in its life cycle. In this short review, we briefly introduce the methodology of life cycle sustainability assessment and review the application of life cycle sustainability assessment focusing on the sustainable energy future. For sustainable development, this framework may help to support the decision-making of products throughout the whole life cycle.

The research on valorizing marine by-products has gained momentum over the past few years due to the limited marine resources and the increasing demand for sustainable sources of functional, nutritional ingredients and biomaterials. Two mean valorization approaches are distinguished in the use of marine by-products: the massive production of fishmeal and fish oil for feed, primarily through the wet reduction process and the new trends of producing high-value bioactive compounds with developed technologies, such as protein hydrolysates, gelatin and collagen, chitin and chitosan, hydroxyapatite, astaxanthin, biofuels, and minerals. This review aims to provide a summary of the bioactive compounds derived from marine by-products, their properties and the various conventional and new technologies used for their valorization over the past two years. The review is organized into four sections that present the valorization of by-products according to four primary marine categories: fish, crustaceans, cephalopods, and bivalves.

Circularity strategies addressing climate change and resource depletion depend on evaluating material and energy flows between biosphere and technosphere. Material flow analysis (MFA) is essential for measuring the physical economy of socioeconomic metabolism, yet its widespread adoption is limited by uncertainties, incomplete inventories, and lack of expertise at the organizational level. Despite this, MFA is gaining traction as a decision-making tool also within companies. This research examines MFA's application to fertilizer flows in green chemistry, and circularity indicators to promote healthy soils rich in organic matter/biodiversity while minimizing environmental impacts. The first substance flow analysis indicators for phosphorus management were introduced in 2006, highlighting losses, stocks, and unaccounted-for flows, but the challenge remains to apply a harmonized model across multiple cases. In nitrogen metabolism, studies estimate hidden flows and storage in the agri-food system, and corporate efforts leveraging MFA can spur similar developments in nutrient flow management, particularly in agriculture.

CO2 capture and conversion using structured porous sorbents and catalysts is a solution to help the decarbonization of emission-intensive industries. Furthermore, porous sorbents have recently been considered for direct air capture to achieve negative CO2 emissions. Several new prototypes and swing adsorption technologies for CO2 capture use structured laminates and honeycomb sorbents to lower the energy penalty and improve process efficiency and kinetics. The challenges lie in tailoring and optimizing structured sorbents for their CO2 working capacity, selectivity over other components, the effect of impurities and humidity, mass and heat transfer kinetics, and mechanical and chemical durability, which are specific to the exhaust system and flue gas composition. Recent developments in the structuring of sorbents are reviewed with a focus on the scalable approaches to improve the performance of postcombustion CO2 capture and direct air capture processes.

Ammonia (NH3) is widely used in the production of vital chemicals such as synthetic fertilizers and nitric acid. It has recently attracted great attention as an energy carrier due to its high hydrogen content (17 wt.% H), ease of transportation, and stability over time. However, for ammonia to fulfil this promise, a more efficient and sustainable method for its synthesis and decomposition must be developed. Significant scientific efforts have been devoted to achieving this via an in-depth understanding of the reaction mechanisms. This mini-review discusses the most relevant developments in heterogenous catalysts for ammonia synthesis and decomposition over the past two years, which has centered on structural and electronic modifications, single atom catalysis, and the use of dual/multiple catalytic sites for N2 and H2 activation to overcome the scaling relationship, and thereby achieve moderate reaction conditions.
