“…The total heterotrophic bacterial count present in the soil samples was determined using the standard dilution plate count technique as described by Amani et al (2018). Ten grams of soil samples were introduced into a conical flask and 100 mL of sterile saline was aseptically added.…”

“…The activities of nitrogen-fixing bacteria are very important because they ensure the reduction in the use of nitrogen fertilizers in plant agriculture. The spread of dust and gases such as sulphur dioxide, and nitrogen dioxide have been the leading consequence of cement production in the environment (Amani et al, 2018;Sandar et al, 2019). These dust particles are spread over large areas through wind and rain with subsequent accumulation in soil and plants (Aneja, 2003;Bilen, 2010;Orji et al, 2016).…”

Nitrogen fixing bacteria play a vital role in transforming atmospheric nitrogen into inorganic form easily available for plant use. However, environmental pollution due to effluent from industrial activities could accumulate in soil, significantly altering the soil chemical and microbiological characteristics, such as nitrogen fixing bacteria. The effect of cement dust on nitrogen-fixing bacteria is presented in this study. Homogenized soil samples 0-20 cm in depth from the cement factory and other communities 200m-2km away from the factory were evaluated for soil physicochemical properties and nitrogen-fixing bacterial bioload using standard procedures. Soil pH, total nitrate, and total phosphate decreased as distance increased away from the factory. Elevated conductivity values of 605.94-621.80(µs/cm) was recorded for soil samples from the factory, indicating the presence of higher dissolved solutes. Total culturable Azotobacter count increased as distance increased away from the factory lcation, with SR1 (Akinbo) recording the highest of 10 4 -10 5 cfu/g, while Azospirillium and Clostridium count significantly reduced. Pollution due to cement production activities may not have had a significant negative effect on the bioload of nitrogen-fixing bacteria. A higher amount of nitrate in soil samples around the cement plant showed that nitrogen-fixing activities occurred at a lower rate compared to the locations farther away from the cement plant.

“…Although Portland cement has been widely used in different geotechnical engineering practices, its application for soil enhancement has been associated with a negative impact on the environment, alongside the increase of carbon dioxide (CO 2 ) emissions during cement production, as cement industries are believed to be responsible for up to 8% of global CO 2 emissions annually [ 1 ]. The application of cement for civil and geotechnical engineering purposes is believed to have contributed to several environmental concerns, including the increase in soil pH level [ 2 ], cement dust accumulation in soil resulting in soil infertility [ 3 ], urban runoff, heat islands, prevention of vegetation growth, and groundwater contamination [ 4 ].…”

Durability, Strength, and Erosion Resistance Assessment of Lignin Biopolymer Treated Soil

et al. 2023

To mitigate the negative environmental effects of the overuse of conventional materials—such as cement—in soil improvement, sustainable engineering techniques need to be applied. The use of biopolymers as an alternative, environmentally friendly solution has received a great deal of attention recently. The application of lignin, a sustainable and ecofriendly biobased adhesive, to enhance soil mechanical properties has been investigated. The changes to engineering properties of lignin-infused soil relative to a lignin addition to soil at 0.5, 1, and 3.0 wt.% (including Atterberg limits, unconfined compression strength, consolidated undrained triaxial characteristics, and mechanical properties under wetting and drying cycles that mimic atmospheric conditions) have been studied. Our findings reveal that the soil’s physical and strength characteristics, including unconfined compressive strength and soil cohesion, were improved by adding lignin through the aggregated soil particle process. While the internal friction angle of the soil was slightly decreased, the lignin additive significantly increased soil cohesion; the addition of 3% lignin to the soil doubled the soil’s compressive strength and cohesion. Lignin-treated samples experienced less strength loss during wetting and drying cycles. After six repeated wetting and drying cycles, the strength of the 3% lignin-treated sample was twice that of the untreated sample. Soil treated with 3% lignin displayed the highest erosion resistance and minimal soil mass loss of ca. 10% under emulated atmospheric conditions. This study offers useful insights into the utilization of lignin biopolymer in practical engineering applications, such as road stabilization, slope reinforcement, and erosion prevention.

“…The well-developed cement and lime industry causes far-reaching transformations of soil [6][7][8][9][10][11][12][13][14][15]. Pollutants are emitted in the form of dusts and gases, which in turn causes their release to all components of the environment, including soils [7,8,10,12].…”

This study presents the influence of the cement and lime industry on the physical and chemical properties of arable soils. In spite of using modern forms of environmental protection against dust emissions, this type of industry causes unfavourable phenomenon of excessive alkalisation of soil. This process is relatively rare in Poland. However, in the Świętokrzyskie Province, it has been responsible for the largest transformation of soils in recent years. The analysis included soil samples taken from five profiles located in the vicinity of Dyckerhoff Polska Sp. z o.o. Nowiny Cement Plant. The study results obtained in 2019 were compared with those obtained in 1978 and 2005. The most attention was paid to soil pH; CaCO3 content; organic carbon and nitrogen content; concentrations of available components such as P2O5, K2O and Mg; and the saturation level of sorption complex with alkaline cations. It was found that long-term imission of pollutants caused significant changes in the basic soil properties, which remain in soils despite the evident decrease in the cement-lime dust emission. These include high pH values, excessive CaCO3 content, high soil saturation with alkaline cations and decreases in total carbon content, which were especially visible in soil humus horizons.
