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.

Cement production is a main source of carbon emissions. Decarbonization options exist, but their climate change mitigation potential, feasibility and environmental implications are still unclear. Here we assess 15 decarbonization options for the European cement industry under current and future conditions. Climate impacts per tonne of clinker produced today in European countries vary between 832 and 1,075 kg CO2-equivalents. Decarbonization options at various maturity levels can mitigate between 7 and 135 Mt CO2-equivalents per year (4–108% of today’s annual emissions from European cement plants), with a range of synergies and trade-offs. Solutions such as alternative fuels or technological improvements reduce climate impacts up to 30%, while a mix of ambitious complementary measures achieves a mitigation of about 50% by 2050. Only rapid and large-scale implementation of carbon capture and storage can approach climate neutrality. Carbon capture for production of e-fuels presents no significant mitigation benefits while it increases other environmental impacts.

“…Conventional fossil fuels, for example, coal and petcoke, made up 54% of thermal energy use in pyro‐processing in Europe in 2017 (GCCA, 2017). Cement kiln development has historically centered around using solid fuels (Akhtar, Ervin, Raza, & Abbas, 2016). Hence, research into and implementation of alternative energy sources in cement production has focused on alternative solid fuels such as secondary fuels and biomass.…”

This paper presents a semi‐quantitative review of measures to achieve net‐zero greenhouse gas emissions (“decarbonization”) in the cementitious materials (CMs) cycle, that is, activities directly related to cement spanning extraction through to end of life. It focuses on the United Kingdom and Europe in order to relate these measures, comprising emissions, energy, and material efficiency, to the policy landscape. We summarize our findings in an annotated CMs cycle, produced by reconciling the diverse yet relatively underdeveloped literature on the topic, to quantify decarbonization potentials of the various measures in a systematic manner. We find that decarbonization measures with significant potential exist along the entire CMs cycle, although upstream (of use), energy, and emission efficiency measures are better quantified than downstream (of use) and material efficiency measures. Notably, the decarbonization potentials of recycling technologies and the ways in which technological advancements may transform the CMs cycle and thus the stocks, flows, and processing of materials, as well as effectiveness of decarbonization measures, are poorly understood. Therefore, this paper provides a basis to systematically understand the effects of emissions, energy, and material efficiency measures on decarbonization of the CMs cycle and, in this context, the interplay between technology, economic actors, and policy. This article met the requirements for a gold–gold JIE data openness badge described at http://jie.click/badges.
