Summary: Biomass-fueled cogeneration plants in the Philippines utilize agricultural residues as feedstock, which in turn results in the generation of ash. This study estimates the potential amount of rice husk and rice straw generation, the energy that can be recovered, and the greenhouse gas emissions reduction potential of using the generated ash in cement-based industries. The transportation of ash and the cost of different ashes are also evaluated.

Summary: Air pollution caused by port activities has become a health problem in coastal cities. To reduce emissions, alternative energy sources and cold ironing technology can be used. This study assesses the emissions of a tanker vessel at berth in Quintero's Bay and finds that a bi-directional energy flow strategy combined with cold ironing significantly reduces emissions.

Summary: Based on a life-cycle assessment using provincial-level data, the adoption of more efficient technologies has reduced the environmental impacts of cement manufacturing in China from 1996 to 2021. The study finds that the introduction of novel suspension preheater rotary kilns has significantly reduced particulate matter emissions, while climate change and fossil depletion remain major environmental burdens. By 2021, technology upgrades had led to a 25% to 53% reduction in pollution from cement manufacturing.

Summary: China, as the largest cement producer and consumer in the world, has experienced significant increases in CO2, SO2, and NOx emissions from the cement industry from 1990 to 2015. However, the introduction of advanced technologies and policy measures has helped in reducing air pollutant emissions, particularly SO2, CO, and PM emissions, while CO2 emissions continue to rise, posing challenges to carbon emission mitigation in the future.

Summary: This work describes various technologies that can enhance the efficiency of cement production process and overall plant performance by reducing thermal losses, costs and carbon dioxide emissions. Different power cycles and alternatives like thermoelectric generators and supercritical fluid cycles are evaluated for their waste-heat recovery potential in the cement industry. The study focuses on clinkerization as the most important process in terms of thermal energy expenditure, and also presents the carbon dioxide emissions from each stage of cement production and estimates the potential for emissions savings in Latin American countries.

Summary: The master plan of energy management for the Thailand iron and steel industry proposed by ISIT includes three scenarios, with a focus on energy reduction and CO2 emission reduction potential in 2030. The study also examines the CO2 abatement cost curve and sensitivity to interest rate changes. By following the baseline scenario, significant potential for energy and CO2 reduction is identified, with the traditional integrated BF-BOF route showing the highest savings. Sensitivity analysis shows that interest rate fluctuations can impact abatement costs.

Summary: Integrated techno-economic modelling suggests that the use of CO2 mineralisation in the cement industry can be profitable and reduce CO2-equivalent emissions by up to a third. This method requires the resulting products to be used in construction and meet the eligibility for emission certificates. The transport of minerals and the composition of the products are also crucial factors.

Summary: This paper designs 45 kinds of configuration choices for data centers by integrating three data centers, three cooling technologies, and five energy supply mixes to seek low-carbon development. It formulates a bi-objective optimization problem to decide newly established data location and configuration with the objective of reducing costs and minimizing power utilization associated with carbon emissions. The pilot study in China shows that China can reduce at least 25% of newly established data center related emissions from 2020 to 2023 under different carbon emissions limitation and propagation delay scenarios. It further suggests future expansion focus on specific regions in China. This paper provides a fresh perspective and valuable attempt at the low-carbon development of data centers.

Summary: The iron and steel industry is crucial for achieving China's carbon neutrality goal, but existing studies lack consideration of constraints such as limited resources, technology diffusion, and carbon emissions reduction. This study developed a model that integrates resources, technologies, and emissions to explore the carbon neutral pathway for the industry. The results highlight the importance of promoting energy-saving technologies and increasing the utilization of scrap for cost savings and carbon reduction.

Summary: Turkiye is a major developing country and the second largest cement exporter in the world. This paper focuses on a detailed exergoeconomic assessment of a rotary burner in a cement factory in Turkiye, aiming to improve energy and exergy performance and reduce energy consumption, exergy costs, and environmental impacts. Through real-time data collection from the factory, the energy and exergy destructions, as well as the exergetic cost distributions for the rotary burner, are calculated using the SPECO method. The use of magnesia-spinel composite refractory bricks and the anzast layer formation leads to a 2.71% reduction in SPECO, equivalent to a saving of $2,280,000 and a yearly decrease of 13.74 MtCO(2) emissions.

Summary: The study uses a linear optimization approach to analyze the cost difference between shared energy infrastructure (smart energy neighborhoods, SENs) and individually planned buildings in idealized building clusters at different degrees of urbanization. With higher emission reduction targets, the advantage of SENs increases within rural environments and can reach up to 16%. However, there are scenarios where sharing energy infrastructure among buildings does not lead to economic advantages, such as in clusters with less than four buildings.

Summary: Increasing the coal resource tax rate will have an impact on China's electric power industry, inhibiting the construction of traditional coal-fired power units while promoting the development of clean energy sources. The eastern region is most affected, with a decrease in the efficiency of existing power transmission lines.
