“…Biochar characteristics are influenced by a number of factors, some of which include biomass type and properties, treatment temperature and residence time. Among these parameters, temperature has been found to have the most significant effect [ 56 , 57 ]. Thus, a proper standardized method needs to be adopted when converting biomass to biochar.…”

Biomass torrefaction is a thermal pre-treatment technique that improves solid fuel properties in relation to its efficient utilization for energy generation. In this study, the torrefaction performance of sewage sludge, a non-lignocellulose biomass and sugarcane bagasse, a lignocellulose biomass were investigated in an electric muffle furnace. The influence of torrefaction temperature on the physiochemical properties of the produced biomaterial were examined. Characterization of the raw and torrefied biomass material were studied using thermogravimetric analysis, Fourier transform infrared spectroscopy (FTIR) analysis and scanning electron microscopy. From the result obtained, it was evident that an increase in torrefaction temperature up to 350 °C caused a 33.89% and 45.94% decrease in volatile matter content of sewage sludge and sugarcane bagasse, respectively. At a higher temperature of 350 °C, the peak corresponding to OH stretching of hydroxyl group decreased in intensity for both biomasses, showing a decomposition of the hydroxyl group as a result of torrefaction. This enriched the lignin content of the torrefied samples, thus making these solid fuels good feedstock for energy production.

“…This thermal treatment, combined with the specific properties of the underlying biomass feedstock, results in biochar with a unique physicochemical structure, such as an exceptionally large surface area capable of capturing and holding minute particles, that serves as a habitat for microorganisms, as well as adsorbs undesirable compounds. Additionally, the produced biochar contains a variety of surface functional sites and mineral components that have a variety of agricultural and environmental applications (Das et al 2020a , b ). As previously discussed, the overall effect of the produced biochar is entirely dependent on the biomass type, temperature, and residence time.…”

Biochar for agronomy, animal farming, anaerobic digestion, composting, water treatment, soil remediation, construction, energy storage, and carbon sequestration: a review

In the context of climate change and the circular economy, biochar has recently found many applications in various sectors as a versatile and recycled material. Here, we review application of biochar-based for carbon sink, covering agronomy, animal farming, anaerobic digestion, composting, environmental remediation, construction, and energy storage. The ultimate storage reservoirs for biochar are soils, civil infrastructure, and landfills. Biochar-based fertilisers, which combine traditional fertilisers with biochar as a nutrient carrier, are promising in agronomy. The use of biochar as a feed additive for animals shows benefits in terms of animal growth, gut microbiota, reduced enteric methane production, egg yield, and endo-toxicant mitigation. Biochar enhances anaerobic digestion operations, primarily for biogas generation and upgrading, performance and sustainability, and the mitigation of inhibitory impurities. In composts, biochar controls the release of greenhouse gases and enhances microbial activity. Co-composted biochar improves soil properties and enhances crop productivity. Pristine and engineered biochar can also be employed for water and soil remediation to remove pollutants. In construction, biochar can be added to cement or asphalt, thus conferring structural and functional advantages. Incorporating biochar in biocomposites improves insulation, electromagnetic radiation protection and moisture control. Finally, synthesising biochar-based materials for energy storage applications requires additional functionalisation.

“…Many studies have presented the positive influence of the application of biochar into the soil. The benefits of such practices include an increase in crop yield and enhanced pesticide degradation (Das et al, 2020;Ding et al, 2017;Peiris et al, 2019). The research conducted proves that biochar has an accelerating effect on NH 3 volatilization in saline soils.…”

A b s t r a c t. Urea is one of the most popular fertilizers in the world. In 2018, the global production capacity of urea reached the level of 210 million metric tonnes. Due to the fact that the world population is growing steadily, the demand for food is increasing, and thus also the consumption of urea. The use of urea-based fertilizers has negative consequences in the form of ammonia volatilization. The solution to this problem may be the use of urease inhibitors. Currently, inhibitors of synthetic origin are available on the market, while the use of inhibitors of natural origin is still being under trial. The use of the most commonly used urease inhibitor -NBPT together with urea causes a reduction in ammonia emissions and has a beneficial effect on crop productivity. At the same time, the search for inhibitors of natural origin is underway, which, apart from reducing ammonia volatilization into the atmosphere, could have a positive effect on crop yields. In this paper, recent advances in this field are reviewed.K e y w o r d s: soil urease, urea, urease inhibitors, ammonia volatilization
