Green Bioprocessing of Algae-Derived Biopolymers
Algae-based biopolymers may be modified by adding additives, plasticizers, and compatibilizers to enhance the intermolecular force of contact between components, and boost material strength, flexibility, and durability. Moreover, biopolymers are widely used in cosmetics, medicines, and food packaging. Furthermore, algal biopolymer could be used as a food additive due to its high nutritional content.

Green Roofs in Green Infrastructure
Green infrastructure (GI) has emerged as a potent strategy to mitigate climate change’s impacts. GI constitutes a network of green spaces encompassing public and private areas, managed as an integrated system to deliver multifarious benefits. This hybrid infrastructure amalgamates green spaces and conventional systems, including forests, wetlands, parks, green roofs, and walls, to bolster ecosystem resilience and furnish ecosystem services, benefiting both the environment and humans.

Groundwater Level Modeling with Machine Learning
Groundwater is the largest global reservoir of liquid freshwater, which is under increasing stress due to overdraft. Groundwater is a vital source of freshwater, supporting the livelihood of over two billion people worldwide. The quantitative assessment of groundwater resources is critical for sustainable management of this strained resource, particularly as climate warming, population growth, and socioeconomic development further press the water resources. Rapid growth in the availability of a plethora of in-situ and remotely sensed data alongside advancements in data-driven methods and machine learning offer immense opportunities for an improved assessment of groundwater resources at the local to global levels.

Heavy metals removal from contaminated solution using seaweed
Heavy metal contamination affects lives with concomitant environmental pollution, and seaweed has emerged as a remedy with the ability to save the ecosystem, due to its eco-friendliness, affordability, availability, and effective metal ion removal rate. Heavy metals are intrinsic toxicants that are known to induce damage to multiple organs, especially when subjected to excess exposure. With respect to these growing concerns, this review presents the preferred sorption material among the many natural sorption materials. The use of seaweeds to treat contaminated solutions has demonstrated outstanding results when compared to other materials. The sorption of metal ions using dead seaweed biomass offers a comparative advantage over other natural sorption materials. This article summarizes the impact of heavy metals on the environment, and why dead seaweed biomass is regarded as the leading remediation material among the available materials.

HEIs, Latin America Circular Economy
HEIs (Higher Education Institutions ) are main actors in the economic development and innovative potential of regions, but now and an increasing number of additional roles are expected. HEIs, as institutional actors, are enablers of social, economic, and cultural development, and sustainability. HEIs can foster collaboration between actors and catalyze public awareness and engagement in CE practices.

Hexavalent Chromium Removal by Electrochemical Processes
Hexavalent chromium (Cr(VI)) is a toxic, mutagenic, teratogenic, and carcinogenic species. Its origin is in industrial activities. Therefore, its effective control is realized on a source basis. Although chemical methods proved effective in removing Cr(VI) from wastewaters, more economic solutions with a minimum sludge production have been sought. Among them, the use of electrochemical processes has emerged as a viable solution to the problem. Much research was conducted in this area.

Human Settlement Research on Climate Change Response
The RCHSCC (the research characteristics, stages and planning of carbon-oriented climate change response research in human settlements based on the literature related to research on carbon-oriented human settlements for climate change) predicts three major trends in the future—climate risk management, carbon technology upgrading and urban security and resilience—and offers three recommendations for governments and planners in terms of climate change adaptation and low-carbon and efficient development in human settlements.
