Summary: This study quantifies the energy consumption and CO2 emissions associated with concrete production through a case study of a concrete plant in Cuenca, Ecuador. The results show that transport of raw materials has the greatest environmental impact, accounting for approximately 80% of the total energy consumption and 79% of CO2 emissions.

Summary: The study aims to extend and supplement previous research on technical objects in the renewable energy sector by analyzing the environmental impact of different stages of a wind power plant's life cycle. Using the Impact 2002+ modeling, the study assessed the ecological effects of a 2 MW Vestas V90/105 m wind farm and found that the production stage had the highest level of harmful effect. However, the use of recycling reduced the negative impacts of the life cycle by 6.5%, particularly in the depletion of fossil resources and human health.

Summary: Wind power, especially onshore wind farms, has been widely used globally. A study conducted on a newly built 40MW wind farm in China with consideration of infrastructure showed that the greenhouse gas emissions intensity was slightly higher compared to nuclear and hydropower, almost comparable to photovoltaic power, yet significantly lower than thermal power and biomass power. Life cycle cost analysis indicated that the levelized cost of electricity from wind power was relatively low at around 0.01-0.02 USD/kWh.

Summary: In this study, the assessment of a renewable energy-based hybrid sulfur-bromine cycle for hydrogen fuel production and effective utilization is conducted. Natural gas-hydrogen blend produced by this cycle is supplied to the combustion subsystems, while solar and wind energy sources are considered for green hydrogen production. The integrated system also includes a drying unit and a desalination unit to provide electricity, heat, and clean water for the community. The overall energy and exergy efficiencies of the system are determined to be 64.43% and 32.24%.

Summary: Transparency is crucial for supporting scientific claims in Life Cycle Assessment (LCA) studies, but the disclosure of secondary datasets and analysis scripts of models is still relatively low. The use of open-source programming languages can enhance transparency and reproducibility. It is also important to disclose secondary datasets and provide justifications for their selection to ensure accurate interpretation of LCA results.

Summary: This study examines the reduction in carbon dioxide emissions resulting from the growth of wind power in India through the development of offshore wind farms. By using evolutionary algorithms and computational techniques, the study analyzes the wind potential in flat and offshore sites. Wind data is collected through the use of LiDAR remote sensing. The study also employs life cycle assessment to quantify the carbon emissions of offshore wind turbines and to guide policy decisions and investments in wind power expansion.

Summary: The design optimization methodology of distributed energy plants considers life cycle impacts to mitigate global energy consumption and carbon emissions. By scaling life cycle inventory data using scaling laws gathered from commercially available systems of various sizes, energy and environmental impacts can be quantified for optimal plant design. This approach demonstrates the effective design of a distributed energy plant and the economic assessment of different configurations, with potential for significant energy savings and cost reductions.

Summary: A study conducted in Malaysia evaluated the life cycle of glucose production from paddy waste. The findings showed that agriculture and the purification process were the main contributors to environmental impact. Converting paddy waste into glucose could be considered as an alternative for managing waste from the paddy supply chain.

Summary: This study provides a systematic analysis on material flow and environmental impacts of a food waste bioconversion plant using black soldier fly larvae, identifying significant emissions of methane, nitrous oxide, and ammonia, as well as quantifying their impacts on global warming potential, acidification, terrestrial and marine eutrophication, and particulate matter. Post-composting emissions, energy consumption, and fertilizer substitution ratio are identified as major contributors to these impacts, with mineral fertilizer and protein feed substitution ratio and energy consumption being identified as the most influential parameters. Control of the post-composting process is crucial in reducing environmental load caused by nitrogen-related emissions.

Summary: By 2040, Ireland is expected to generate 53,000 tonnes of blade waste from on-shore wind farms, with recycling of composite material blades being costly. Green Public Procurement can help drive demand for repurposed blade products, potentially creating jobs in high unemployment areas and increasing supply chain resiliency. Focusing on creating job opportunities and supply chain resilience is crucial for post-Covid recovery in Ireland.
