Sustainable Textiles from Unconventional Biomaterials
Various studies have shown that vegan leather alternatives are particularly suitable because they mimic the properties of real leather, and the qualities of the bio-based materials combined with textile substrates are relatively close to real leather. Cactus plants require less water and can completely replace real leather. The use of cactus as a source of sustainable textiles and leather offers numerous environmental benefits. This is due to the fact that harvesting the cactus does not harm the plant or its roots, allowing it to keep growing and sequestering carbon dioxide.

Properties of Recycled Steel Fibers-Incorporated Concrete
Accumulating vast amounts of pollutants drives modern civilization toward sustainable development. Construction waste is one of the prominent issues impeding progress toward net zero. Pollutants must be utilized in constructing civil engineering structures for a green ecosystem. Large-scale production of industrial steel fibers (ISFs) causes significant damage to the goal of a sustainable environment. Recycled steel fibers (RSFs) from waste tires have been suggested to replace ISFs. Using RSFs can help reduce pollution due to ISFs production; on the other hand, it can improve the performance of the concrete at a low cost.

Enhancement of Anaerobic Digestion with Nanomaterials
The number of research reporting the addition of nanomaterials to enhance the process of anaerobic digestion has exponentially increased. The benefits of this addition can be observed from different aspects: an increase in biogas production, enrichment of methane in biogas, elimination of foaming problems, a more stable and robust operation, absence of inhibition problems, etc. Several hypotheses have been formulated, with the effect on the redox potential caused by nanoparticles probably being the most accepted, although supplementation with trace materials coming from nanomaterials and the changes in microbial populations have been also highlighted. The types of nanomaterials tested for the improvement of anaerobic digestion is very diverse, although metallic and, especially, iron-based nanoparticles, are the most frequently used.

Phytoremediation of Domestic Wastewater
A circular economy (CE) based strategy is essential to progress toward Sustainable Development Goals (SDG). CE is centered on the conversion of waste into meaningful products and resource efficiency with the objective of promoting resource reuse. This study presents the potential of CE approaches in the phytoremediation of wastewater and energy recovery using hydroponic tanks. The integration of phytoremediation with bioenergy, construction and lifespan of hydroponic tanks in phytoremediation of wastewater, selection of aquatic plants, and the expected challenges in the implementation of CE in phytoremediation of wastewater were discussed. It further elucidates a comprehensive circularity assessment methodology that would enable and support a strategic CE framework for phytoremediation techniques in wastewater treatment. Additionally, a complete view of the feedstock conversion process into valuable end products was discussed in this CE strategic study. The findings obtained provided insights into the relative growth rate of the plant-based biomass harvested from the phytoremediation of domestic wastewater. It also provided information on the economic and technical feasibility of wastewater phytoremediation using hydroponic tanks for simultaneous recovery of treated water and plants’ biomass to enable large-scale implementation. Furthermore, optimizing resource recovery and bioenergy generation, developing new approaches and solutions, and improving process stability would help encourage and enhance the adoption of the CE framework in the phytoremediation of domestic wastewater.

Cellular Automata in Modeling and Predicting Urban Densification
The creation of an accurate simulation of future urban growth is considered to be one of the most important challenges of the last five decades that involves spatial modeling within a GIS environment. Even though built-up densification processes, or transitions from low to high density, are critical for policymakers concerned with limiting sprawl, the literature on models for urban study reveals that most of them focus solely on the expansion process. Although the majority of these models have similar goals, they differ in terms of implementation and theoretical assumptions. Cellular automata (CA) models have been proven to be successful at simulating urban growth dynamics and projecting future scenarios at multiple scales.
