Brazil’s Formal E-Waste Recycling System
Disruptive innovation has led to the increased obsolescence and accelerated replacement of electrical and electronic equipment, resulting in the rapid growth of waste electrical and electronic equipment (e-waste) worldwide. However, amidst the challenges in e-waste management, the recovery of secondary raw materials from e-waste presents an attractive business opportunity.

Energy Harvesting Opportunities in Geoenvironmental Engineering
Energy harvesting (EH)—or energy scavenging—methods and technologies have been developed to reduce the dependence on traditional energy sources, namely fossil fuels, and nuclear power, also responding to the increase in energy demands for human activities and to fulfill sustainable development goals. EH in geoenvironmental works and the surrounding soil and water environment includes a set of processes for capturing and accumulating energy from several sources considered wasted or unusable associated with soil dynamics; the stress and strain of geomaterials, hydraulic, vibrations, biochemical, light, heating and wind sources can be potential EH systems.

Adverse Impact of Additive Carbon Material on Microorganisms
Biochar could be a brilliant additive supporting the anaerobic fermentation process. However, it should be taken into account that in some cases it could also be harmful to microorganisms responsible for biogas production. The negative impact of carbon materials could be a result of an overdose of biochar, high biochar pH, increased arsenic mobility in the methane fermentation solution caused by the carbon material, and low porosity of some carbon materials for microorganisms.

Recycling and Reuse ECOSYSTEM
Daikin Europe N.V. (DENV), Daikin Central Europe (DACE), the National Technical University of Athens (NTUA) and the Society for Materials and Energy Applications (MAT4NRG GmbH) are the four partners of the consortium behind the Retradeables project that receives EU funding. The key objective of the ongoing project is to realise the first circular economy ecosystem to strongly promote the efficient management of used gases, offering sustainability and accountability to the HVAC-R industry and reducing environmental pollution stemming from F-gas emissions. This is exactly the mission of the so-called “3R ECOSYSTEM” that is currently under development to bring total innovation to the HVAC-R industry, adding value to used refrigerants that will be treated as an asset instead of a waste to be destroyed.

Enhancing Extracellular Electron Transfer in Environmental Biotechnology
Extracellular electron transfer (EET) is a biological mechanism that plays a crucial role in various bioelectrochemical systems (BESs) and has substantial implications for renewable energy production. By utilizing the metabolic capacities of exoelectrogens, BESs offer a viable and environmentally friendly approach to electricity generation and chemical production; however, the diminished effectiveness of EET remains a hindrance to their optimal application in practical contexts.

Critical Risk Factors of Implementing Public–Private Partnership Projects
Due to the fact that risks can cause project delays and increase project implementation costs, successful construction project completion requires effective and holistic risk management. Identification and evaluation of critical risk factors (CRFs) associated with different types of projects are the most significant components of accurate risk management.

Optimizing Smart Energy Infrastructure in Smart Ports
To lessen the environmental impact of the maritime industry, ports must decarbonize in conformity with various standards such as the European Green Deal and the Sustainable Development Goals (SDGs). In this regard, they must demonstrate integrated low-emission energy production, distribution, and supply, as well as sustainable alternative infrastructure for refueling ships, cargo handling equipment, and other vehicles inside port boundaries. To address this issue, ports must progress toward smartening their operations. This requires intelligent infrastructure and components, with smart energy infrastructure being one of the most crucial ones. It is a part of port energy management systems (EMSs) and works based on modern technology to balance energy demand, distributions, and supply while transitioning to renewable energies.

Wind Turbines Operating under Hazard Environmental Conditions
Renewable energy use has accelerated due to global warming, depleting fossil fuel reserves, and stricter environmental regulations. Among renewable options, solar and wind energy have shown economic viability and global growth. Horizontal axis wind turbines offer promising solutions for sustainable energy demand. Since wind turbines operate in an open environment, their efficiency depends on environmental conditions. Hazard environmental conditions, such as icing, rainfall, hailstorms, dust or sand, insects’ collisions, increased humidity, and sea spray, result in degraded aerodynamic characteristics.

Dye-Wastewater Valorization Using Up-Flow Anaerobic Sludge Blanket Reactors
Dye-containing effluent generated in textile industries is polluting and complex wastewater. It should be managed adequately before its final destination. The up-flow anaerobic blanket (UASB) reactor application is an ecofriendly and cost-competitive treatment.
