“…With an increasing carbonization temperature, the volatile matter contents of the bio-char gradually decreased while the ash content of the char increased [39]. Biochar yield decreased with increasing pyrolysis temperature due to biomass decomposition and thermal degradation of lingo-cellulosic structures [11,40].…”

Background Ethiopia’s energy relies mainly on biomass sources, residues of crops and animal dung collections. Over 90% of domestic energy needs in Ethiopia are met by biomass, which contributes to deforestation and climate change. This study investigates the usage of water hyacinth and country’s largely produced agricultural waste (groundnut shells) for the production of briquettes using potato peels as a binder. Methods Water hyacinth, groundnut shells, and potato peel waste were used for production of briquettes. Briquettes were prepared using three parameters; temperature (350 ℃, 450 ℃ and 550 ℃), particle size (0.5, 1 and 1.5mm) and mixing ratio (25%, 50% and 75%). Physical properties and calorific values for the developed briquettes were determined using FTIR machine and bomb calorimeter. Central composite design by the design expert was used to design the experiment, and response surface methodology was used to optimize the calorific value of the produced briquettes. Statistical analysis tool such as analysis of variance was employed to show whether the process variables were statistically significant on the response variable (P < 0.05). Results The developed briquettes had the highest calorific value, 25.52 MJ/kg. The maximum bulk density and durability of the produced briquettes were 0.553% and 97.86%, respectively. The moisture content, volatile matter, ash content, and fixed carbon content of water hyacinth biomass were 8.14%, 68.49%, 10.3% and 13.06%, respectively. The moisture content, volatile matter, ash content, and fixed carbon of the groundnut shells were 9.2%, 66.84%, 3.615% and 20.34%, respectively. The produced briquettes had a moisture content ranging from 8.470–11.760%, and ash content ranging from 5.850–8.750%. Temperature, particle size and mixing ratio were statistically significant on the calorific value of the briquettes (p < 0.05). The optimised briquettes have a calorific value of 24.544 MJ/kg, at a temperature, particle size and mixing ratio of 453.380℃, 0.999 mm, and 50%, respectively. Conclusion The produced briquettes had good calorific value, bulk density and durability, and were suitable for cooking and heating purposes. This revealed that agricultural wastes could be used to augment the energy sources pool to protect the environment and create social stability in the community.

“…The need of large‐scale production of biochar is a general requirement for continuous production. However, during pyrolysis, quality control is a crucial issue that needs for appropriate design of reactor and further proper operation (Li et al., 2022). In general, 6 different types of pyrolysis reactors are used, namely, earthen kiln, fixed bed, fluidized bed, rotary kiln, spouted bed, and auger reactors (Mohan et al., 2014).…”

The generation of sewage wastewater is unavoidable due to the continual increase in the global population that paves the way to appropriate disposal management. Sewage wastewater treatment and consequent generation of sewage sludge (SS) are well connected with global environmental issues. Upon risk assessment on different SS disposal methods, converting SS into biochar, that is, sewage sludge biochar, can be recommendable management. It is well‐proven for excellent positive impacts, such as nutrient enhancement, and healthier plant growth, and mitigates the emissions of greenhouse gases while amending with agricultural soil. However, the outcome features of SSB significantly vary with pyrolysis temperature and its elemental constituents. In addition, many studies revealed that the process temperature is key to responsible for the desirable properties and functioning of SSB. In this context, many countries support to the development of a futuristic strategy for SS management toward producing SSB and its utilization in agriculture. This review compiles studies into SSB's ability to promote a sustainable effect on the total worldwide output volume. Furthermore, the generation of SSB is also analyzed from a socioeconomic standpoint in relation to other common SS disposal management strategies.

Soil amendments may enhance crop yield and quality by increasing soil nutrient levels and improving nutrient absorption efficiency, potentially through beneficial microbial interactions. In this work, the effects of amending soil with straw-based carbon substrate (SCS), a novel biochar material, on soil nutrients, soil microbial communities, and maize yield were compared with those of soil amendment with conventional straw. The diversity and abundance of soil bacterial and fungal communities were significantly influenced by both the maize growth period and the treatment used. Regression analysis of microbial community variation indicated that Rhizobiales, Saccharimonadales, and Eurotiales were the bacterial and fungal taxa that exhibited a positive response to SCS amendment during the growth stages of maize. Members of these taxa break down organic matter to release nutrients that promote plant growth and yield. In the seedling and vegetative stages of maize growth, the abundance of Rhizobiales is positively correlated with the total nitrogen (TN) content in the soil. During the tasseling and physiological maturity stages of corn, the abundance of Saccharimonadales and Eurotiales is positively correlated with the content of total carbon (TC), total phosphorus (TP), and available phosphorus (AP) in the soil. The results suggest that specific beneficial microorganisms are recruited at different stages of maize growth to supply the nutrients required at each stage. This targeted recruitment strategy optimizes the availability of nutrients to plants and ultimately leads to higher yields. The identification of these key beneficial microorganisms may provide a theoretical basis for the targeted improvement of crop yield and soil quality. This study demonstrates that SCS amendment enhances soil nutrient content and crop yield compared with conventional straw incorporation and sheds light on the response of soil microorganisms to SCS amendment, providing valuable insights for the future implementation of this material.
