Towards the Commercialization of Solid Oxide Fuel Cells
The solid oxide fuel cell (SOFC) has become a promising energy conversion technology due to its high efficiency and low environmental impact. Though there are several reviews on SOFCs, comprehensive reports that simultaneously combine the latest developments in materials and integration strategies are very limited. This paper addresses those issues and discusses SOFCs working principles, design types, the fuels used, and the required features for electrodes and electrolytes.

Towards Sustainable Pasture Agrolandscapes
Reliable environmental audits and impact assessments are essential to achieve effective pasture utilization and ensure the production of high-quality livestock products. Pasture agrolandscapes are complex and dynamic systems that involve the interaction of various components, such as soil, vegetation, climate, and land use. These landscapes are crucial not only for the production of high-quality livestock products but also for maintaining environmental health and providing ecosystem services

Towards Higher Quality of Recycled Plastics
The increasing consumption of plastics and plastic products results in correspondingly substantial volumes of waste, which poses considerable environmental burdens. With the ongoing environmental actions, the application of circular economy on this waste stream is becoming inevitable. The quality of recycled plastic is generally determined by the homogeneity of the recovered plastic feed.

Towards Circular Economy for More Sustainable Apparel Consumption
The apparel industry causes environmental problems, particularly due to the shortening life cycle of garments and fast-fashion’s throw-away culture. The circular economy provides solutions to minimise and prevent these problems through innovative circular business models, which require changes in consumer behaviours. With the lens of environmental psychology, we analyse consumers’ willingness to acquire circular apparel considering four approaches on clothing life-cycle extension. We conducted an online questionnaire among Brazilian and Dutch consumers and tested if the Value-Belief-Norm (VBN) theory can explain the willingness of consumers to purchase circular apparel. Our results indicate that, overall, the variables from the VBN theory explain circular behaviour in the apparel industry and that the paths suggested by the model are supported by our analyses. Additionally, we tested and found that when all of the variables from the VBN theory were controlled for, materialistic values did not explain circular behaviours in the apparel industry among Brazilian respondents. However, they had a positive influence on some circular apparel behaviours among Dutch consumers. Overall, materialistic values did not play an important role in predicting willingness to consume circular clothing. Furthermore, the results suggest that the VBN theory predicts willingness to consume circular apparel better in the Netherlands compared to Brazil, suggesting that this behaviour may be perceived as more effortful for the Brazilian population. However, we highlight the need for future research.

Toward a Feminist Agroecology
Agroecology is gaining ground as a movement, science, and set of practices designed to advance a food systems transformation which subverts the patterns of farmer exploitation currently entrenched in dominant agricultural models. A feminist agroecology focuses on redressing unequal gender relations as well as other intersecting relations of marginalization such as race, class, caste, and ethnic identity.

Tougher Plastics Ban Policies in China
After the Chinese government's new plastics ban policies issued in 2020, another set of tougher plastics ban measures were introduced in Shanghai, China in 2021. The tougher plastic ban polices completely forbade the usage of plastic carrier bags and required all supermarkets to sell only cloth or nylon carrier bags priced from RMB 1.0 to 39.0. Tougher plastics ban policies are penalty-oriented. The tougher plastics ban policies produce positive plastics reducing effects by observing significantly decreased usage of charged carrier bags by 46%, and significantly increased usage of old plastic bags and reusable bags by 117% and 36%, respectively. Policy execution loopholes are found in some supermarkets which do not follow the tougher plastics ban measures. Fortunately, the spill-over effects from tougher-measure-executing supermarkets fix this issue to some extent. The tougher 2021 measures fail to be the most powerful impacting factor on people’s usage of each type of bag. To produce better plastics reducing results, other bag-targeted measures are necessary.

Total Petroleum Hydrocarbons in Seawater
Total Petroleum Hydrocarbons (TPH) is a term used to represent petroleum (crude oil) that consists of a blend of thousands of compounds. They are referred to as hydrocarbons because almost all consist of hydrogen and carbon. A crude oil spill is a common issue during offshore oil drilling, transport and transfer to onshore. Second, the production of petroleum refinery effluent is known to cause pollution due to its toxic effluent discharge. Sea habitats and onshore soil biota are affected by TPH as a pollutant in their natural environment. Crude oil pollution in seawater, estuaries and beaches requires an efficient process of cleaning. To remove crude oil pollutants from seawater, various physico-chemical and biological treatment methods have been applied worldwide. A biological treatment method using bacteria, fungi and algae has recently gained a lot of attention due to its efficiency and lower cost.

Tools for Shoreline Change Analysis and Detection
A shoreline is the point of the physical border between land and water. While this definition looks simple, it is indeed challenging in its practical application. The position of the shoreline changes through time due to cross-shore and alongshore sediment movement in the littoral zone, and through changes in water levels. Shoreline change analysis and detection studies have progressed from using simple observation (description) from historical maps and topographical maps to employing high-resolution multi-temporal satellite images with remote sensing and Geographic Information System (GIS) approaches for a better understanding of the subject.

Tools for Optimization of Biomass-to-Energy Conversion Processes
Biomasses are renewable sources used in energy conversion processes to obtain diverse products through different technologies. The production chain, which involves delivery, logistics, pre-treatment, storage and conversion as general components, can be costly and uncertain due to inherent variability. Optimization methods are widely applied for modeling the biomass supply chain (BSC) for energy processes.
