Pig Manure and Heavy Metals in Rice
Pig manure (PM) is often highly enriched in heavy metals, such as Cu and Zn, due to the wide use of feed additives. To study the potential risks of heavy metal accumulation in the soil and rice grains by the application of PM and other organic manure, a four-year field experiment was conducted in the suburb of Shanghai, southeast China. The contents of Cu, Zn, Pb, and Cd in the soils and rice plants by the treatments of PM and fungal culturing residues (FCR) show a trend of annual increase. Those in the soils and rice by the PM treatment are raised even more significantly. Cu and Zn contents in the soil and rice roots by the PM are significantly higher than those by the non-fertilizer control (CK) during the four years, and Pb and Cd also significantly higher than CK in the latter two years.

Extremely Acidic Eukaryotic (Micro) Organisms
Acid Mine Drainage (AMD) results from sulfide oxidation, which incorporates hydrogen ions, sulfate, and metals/metalloids into the aquatic environment, allowing fixation, bioaccumulation and biomagnification of pollutants in the aquatic food chain. Acidic leachates from waste rock dams from pyritic and (to a lesser extent) coal mining are the main foci of Acid Mine Drainage (AMD) production.

Urban Wetlands
Wetlands are a critical part of natural environments that offer a wide range of ecosystem services. In urban areas, wetlands contribute to the livability of cities through improving the water quality, carbon sequestration, providing habitats for wildlife species, reducing the effects of urban heat islands, and creating recreation opportunities.

Green Diesel Production by Hydrodeoxygenation
Non-renewable fossil fuels and the air pollution associated with their combustion have made it necessary to develop fuels that are environmentally friendly and produced from renewable sources. Vegetable oils are a renewable source widely used to produce biofuels due to their high energy density and similar chemical composition to petroleum derivatives, making them the perfect feedstock for biofuel production. Green diesel and other hydrocarbon biofuels, obtained by the catalytic deoxygenation of vegetable oils, represent a sustainable alternative to mineral diesel, as they have physico-chemical properties similar to derived oil fuels.

Selection of Mercury-Resistant PGPR Strains
Mercury (Hg) is an element with a high level of toxicity that poses a serious environmental threat. It is possible for Hg to enter the food chain and consequently affect human health, even at very low concentrations.

Integration of Environmental Justice and Sustainability in Practice
The environmental justice (EJ) movement has been a key factor in the United States’ struggle to provide a healthy environment for all to thrive. The origins of the movement date as far back as the 1960’s, led primarily by people of color and low economic status communities living in America’s most polluted environments. More recently, the just sustainability movement calls for the inclusion of EJ considerations, including social justice, equity, and human rights, into sustainability science and initiatives.

Archimedes Screw Turbines
Archimedes Screws Turbines (ASTs) are a new form of generators for small hydroelectric powerplants that could be applied even in low head sites. ASTs offer a clean and renewable source of energy. They are safer for wildlife and especially fish. The low rotation speed of ASTs reduces negative impacts on aquatic life and fish. Considering the flexibility and advantages of ASTs, they offer economic, social, and environmental advantages to support sustainable development to: - Increase the number of suitable sites and maximize power generation.- Retrofit old dams or upgrade current dams or mills to make them economically (power generation) and environmentally (renewable energy) reasonable.- Reduce the hydroelectricity major operational and/or maintenance costs.- Reduce the disturbance of natural erosion and sedimentation processes.- Make hydropower generation safer for aquatic wildlife, especially for fish.- Generate electricity for small communities, developing countries, and regions with limited access to the power grid or other infrastructures, or regions that are hard to access or connect to the power grid.

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.

Biological-Based Produced Water Treatment Using Microalgae
Produced water (PW) is the most significant waste stream generated in the oil and gas industries. The generated PW has the potential to be a useful water source rather than waste. While a variety of technologies can be used for the treatment of PW for reuse, biological-based technologies are an effective and sustainable remediation method. Specifically, microalgae, which are a cost-effective and sustainable process that use nutrients to eliminate organic pollutants from PW during the bioremediation process. In these treatment processes, microalgae grow in PW free of charge, eliminate pollutants, and generate clean water that can be recycled and reused. This helps to reduce CO2 levels in the atmosphere while simultaneously producing biofuels, other useful chemicals, and added-value products.
