“…Inorganic binders offer advantages such as low cost, high strength, and environmental friendliness, making them attractive alternatives to traditional binders. Common inorganic binders include clay, cement, gypsum, and calcium-based binders. − Compared to other inorganic binders, calcium-based binders exhibit superior performance in binding strength and sulfur fixation. This makes them more suitable for the production of formed coke with desirable characteristics, such as high fixed carbon content, low moisture content, and reduced pollutant emissions, which is a crucial advantage in addressing the environmental concerns associated with the burning of carbonaceous materials, as sulfur emissions contribute to air pollution and acid rain.…”

In order to address the low thermal efficiency of low-rank coal combustion and the accompanying serious environmental issues, formed coke was prepared using a carbonization consolidation method with low-rank coal semi-coke. The test for briquetting and carbonation consolidation conditions revealed that the optimal parameters were a briquetting pressure of 93.63 MPa, moisture content of 16%, Ca(OH)2 binder amount of 10%, and a CO2 concentration of 30% at 20 °C. Under these conditions and a carbonation consolidation time of 60 min, high-quality formed coke was produced, exhibiting a compressive strength of 1256.2 N/a, redrying strength of 286.2 N/a, and a dropping strength of 10.6 number/a. The combustion characteristics of the prepared formed coke were investigated, revealing that ignition temperatures (345.39 °C), burnout temperatures (495.57 °C), and peak of the maximum weight loss rate temperatures (437.93 °C) are slightly higher than those of bituminous coal. The low calorific value of the briquette was 20.4 MJ/kg. During the combustion process, the emission concentrations of SO2, NO X , and solid particles from the formed coke were significantly lower than those of bituminous coal, indicating that it is a cleaner energy source. Moreover, adding Ca(OH)2 effectively reduced SO2 emissions and achieved sulfur fixation and emission reduction.

With the growth of the construction industry, the role and importance of sustainable construction practices are also increasing. This study reviews the various advancements in the field of bio-based construction materials, including bio-aggregates, bio-binders, and bio-bricks. The origins of our centuries-old construction methods can be found in bio-based concrete materials, which have been revived and modernized to meet the needs of present-day construction. The integration of recovered construction and agricultural wastes plays a significant role in bringing these materials into the competitive building sector, aligning with sustainability goals. This study provides an in-depth examination of the processes and compositions required to achieve the desired strength and durability of bio-based materials. By comprehensively analyzing global research data, this study offers insights into the successful incorporation of biomaterials, emphasizing their potential to reduce carbon emissions and promote the responsible utilization of natural raw materials. This pathway moving toward more sustainable construction practices underscores the environmental benefits of bio-based concrete materials.
