Carbon dioxide removal (CDR) is necessary to minimize the impact of climate change by tackling hard-to-abate sectors and historical emissions. Direct air capture storage (DACS) an important CDR technology, but it remains unclear when how DACS can be economically viable. Here, we use a bottom-up engineering-economic model together with top-down technological learning projections calculate plant-level cost trajectories for four technologies. Our analysis demonstrates that costs these...
Coastal enhanced weathering (CEW) is a carbon dioxide removal (CDR) approach whereby crushed silicate minerals are spread in coastal zones to be naturally weathered by waves and tidal currents, releasing alkalinity removing atmospheric (CO2). Olivine has been proposed as candidate mineral due its abundance high CO2 uptake potential. A life cycle assessment (LCA) of silt-sized (10 μm) olivine revealed that CEW's life-cycle emissions total environmental footprint, i.e., penalty, amount around...
Abstract. Ocean alkalinity enhancement (OAE) is an emerging strategy that aims to mitigate climate change by increasing the of seawater. This approach involves ocean enhance its capacity absorb and store carbon dioxide (CO2) from atmosphere. chapter presents overview technical aspects associated with full range OAE methods being pursued discusses implications for undertaking research on these approaches. Various have been developed implement OAE, including direct injection alkaline liquid...
The efficacy of magnesium oxide (MgO)-bentonite clay nanocomposite (MgO nanoparticles embedded in powdered bentonite clay) for water and wastewater treatment applications is examined herein. Congo red (CR), a widely used azo dye, was as the model contaminant. For CR concentrations ≤120 mg/L, optimum dosage ≤1 g/L, achieving removal ≥99% contact times (mixing durations) ≤10 min, whereas temperature pH had no significant effect on process. dye followed pseudo-second-order than first order...
Biogas production from animal manure can address many negative impacts of traditional energy generation and also improve living conditions in rural communities Egypt, the case study herein, further afield. Even though techno-economical aspects household biogas digester technology have been thoroughly studied, its environmental sustainability, especially under Egypt's conditions, remains largely unknown. To this end, life cycle inventory data were collected typical fixed-dome digesters...
Existing wave energy technology has been designed for ocean waves, which, however, shorten the lifespan of converters and mooring systems. Furthermore, commissioning maintenance in harsh conditions are challenging expensive. For to realise its full potential become commercially attractive, smaller, more economical, resilient should be first introduced, tested, optimized, as was case with wind energy. Low seas such Mediterranean, Baltic, Caspian, Black, Red Sea ideal this purpose. However,...
Over the previous two decades, a diverse array of geochemical negative emissions technologies (NETs) have been proposed, which use alkaline minerals for removing and permanently storing atmospheric carbon dioxide (CO2). Geochemical NETs include CO2 mineralization (methods react with CO2, producing solid carbonate minerals), enhanced weathering (dispersing in environment drawdown) ocean alkalinity enhancement (manipulation chemistry to remove from air as dissolved inorganic carbon)....

As the scale of organic cultivation sector keeps increasing, there is growing demand for reliable data on agriculture and its effect environment. Conventional uses chemical fertilizers pesticides, whilst mainly relies crop rotation fertilizers. The aim this work to quantify compare environmental sustainability typical conventional pepper systems. Two open field cultivations, both located in Anthemountas basin, Northern Greece, are selected as case studies. Life cycle assessment (LCA) used...
The energy and environmental performance of photovoltaic (PV) panel cooling, when using phase change materials (PCMs), was examined. Actual, long-term field data were collected from a PV PV-PCM system, both operating under Mediterranean conditions (Greece). analysis revealed that even though cooling increases (9.4%) the panel's output, PCM is associated with high initial investment, leading to low energy-return-on-investment values (1.79) compared (4.94). High payback times observed for (⁓14...
