“…The primary technological pathways for reducing carbon emissions in the cement industry encompass several strategies: utilizing alternative fuels, adopting low-carbon cement, and implementing carbon capture, utilization, and storage. Among these, the use of "alternative fuels" has become the preferred carbon emission reduction process in the current stage of the global cement industry due to its significant impact on reducing carbon emissions, relatively high technological maturity, cost-effectiveness in CO 2 emission reduction, and minimal impact on the original production system [20,21]. In order to control the generation of CO 2 in cement production from the source, it is imperative to enhance the kiln combustion process under the premise of keeping the existing new dry cement production process basically unchanged.…”

This study aimed to improve the safety and economy of cement production and to investigate the gasification performance and tar properties of wheat straw in a small electrically heated bubbling fluidized bed by varying three factors, namely, gasification reaction conditions, fuel quality and type, and the natural environment, so as to promote the application of the low-temperature gasification of biomass in the cement industry. The gasification experiment was carried out at temperatures of 550–700 °C, air equivalence ratios of 0.1–0.2, moisture contents of 5.25–24%, blended rubber ratios of 0–100%, and furnace vacuums of 0–0.03 within the parameter ranges, and the component analyses of the produced gases and tars were carried out by gas chromatography (GC) and gas chromatography–mass spectrometry (GC-MS). The experimental findings revealed that the optimal operating conditions for gasification were attained at a temperature of 650 °C, an equivalence ratio of 0.15, a moisture content of 5.25%, a rubber blending ratio of 0, and a vacuum degree of 0. Under these conditions, the concentrations of combustible components (H2, CH4, and CO) in the produced gas were 4.01%, 4.60%, and 21.05%, respectively. The carbon conversion rate was 62.40%, with the cold gas efficiency of 39.37%. The lower heating value of the produced gas was 5.915 MJ/Nm3, accompanied by a tar yield of 118.15 g/Nm3 and lower heating value of 3.385 MJ/Nm3.

The combustion of fossil energy has resulted in the emission of a substantial quantity of greenhouse gases, leading to the occurrence of global warming and a cascade of climate-related issues. Among many fossil energy consuming and heavily polluting processes, cement manufacturing from the precalciner kiln system stands out as a significant contributor. Over the past few decades, a substantial body of research has been conducted with the aim of reducing both the energy consumption and environmental impact associated with this industry through the utilization of alternative fuel sources. The integration of alternative fuels (plastic waste, meat and bone meal, municipal solid waste, refuse-derived fuel, tire-derived fuel, wood waste, etc.) in cement manufacturing has garnered considerable attention due to its efficacy in substituting the thermal energy requirements historically met by fossil fuels (coal, petroleum coke, oil, natural gas, etc.), thereby mitigating greenhouse gases emissions (CO 2 ). The harshly alkaline conditions, elevated temperatures, and prolonged residence time of the rotary kiln facilitate the incineration of a diverse range of waste materials and hazardous substances (municipal solid waste, tirederived fuel, dioxins and furans, heavy metals, etc.). However, alternative fuel still causes many problems. In recent years, with the increasingly attractive carbon emissions, biomass has proven to be a capable energy to meet the growing demand for clean energy. Biomass alternative fuels used to replace fossil fuels may reduce carbon emissions, and this is the main goal of climate strategy in various countries in the world. This paper presents the latest advancements in the utilization of biomass alternative fuels within the cement industry, and thoroughly examines and deliberates upon many scholarly articles pertaining to this particular research area. Studies on the impact of biomass alternative fuels on environmental emission, and challenges that may encounter when using biomass replacement fuel have also been included in this review. This paper furnishes a comprehensive understanding and elucidation of biomass alternative fuels, encompassing their implementation in the cement industry, while accentuating their salutary ramifications on the environment. Subsequently, we scrutinize the principal quandaries pertaining to the cocombustion of biomass alternative fuel in the cement industry and proffer feasible proposals for targeted solutions.
