The unregulated discharge of untre”ted ’IE Into the environment can promote eutrophication processes, ecosystem imbalance, and pose detrimental effects to humans, animals, and plants. Therefore, SDG 12’s target 12.5 for this goal highlights waste management as a worldwide concern. Thus, when released without receiving proper treatment, the effluent poses a serious threat to the environment. The treatment of these effluents presents an environmental challenge because of the high pollutant load, vast volumes produced, and seasonal fluctuation. They include a significant number of organic compounds with high COD and color values, which have the potential to result in serious pollution issues. Although their physicochemical characteristics are quite diverse, even among those of the same origin, they generally consist of organic and inorganic pollutants present in high concentrations, nutrients (nitrogen, phosphorus, and potassium), toxic compounds (including heavy metals), pesticides, phenols, and components that may influence air, water, and soil quality. The raw materials’ source, products’ nature, operations, and the phases in the processing all affect the composition and quantity of AIE. The produced AIE include fruit, cassava, potato, vinasse, coffee, dairy, cheese whey, beverage, palm oil, winery, elderberry juice production effluent, slaughterhouse effluents, and olive mill and pulp and paper mill wastewaters. Consequently, considerable amounts of solid waste and effluents with major pollution-causing qualities are produced. Large quantities of energy, water, and soil are needed for these processes. Sugarcane, grains, oilseeds, cassava, milk, and animal slaughter are the primary sources of products from the agro-industrial sectors. Thus, it leads to the generation of agro-industrial effluents (AIE) at high rates and volumes. Modern trends have seen a drive toward waste transformation into useful resources rather than simply treatment to create a more sustainable society. Their primary structural elements contain significant amounts of lignin, hemicelluloses, starch, and cellulose. ![]() Considering the rapid rate of population development, excess utilization of natural resources, and rising energy consumption per individual, it is frequently unavoidable that highly sophisticated, renewable, and affordable wastes from agro-industries will increase. They are also a significant contributor to the issue of environmental contamination on a global scale. ![]() The industries produce much biomass, which is a key component of the bioeconomy. Agro-industries are one of the largest contributors to the global economy, producing an estimated mean value of 23.7 million tonnes of food every day, particularly in developing countries that frequently rely on subsistence farming and income from formal and/or unofficial agro-industries. Thus, this study proves that the HWSB made from biomass waste can potentially help preserve nonrenewable resources and promote zero-waste attainment and principles of circular economy.Īgro-industries have increased more than thrice over the past five decades as a consequence of improved agricultural soil, technical advancements brought about by the green revolution, and growing population that was expedited. Maximum contaminants elimination was attained at 30% AIE and 2-day HRT. During biokinetic studies, the modified Stover models were found to be perfectly suited for the observed measurements with R 2 values 0.9741 attained for COD. Findings indicated 76.52% and 66.97% reduction in COD and color, respectively. The performance of CFBS was analyzed in terms of COD and color removal. AIE concentration and HRT were optimized using response surface methodology (RSM) as the process variables. The use of a bioreactor with hydraulic retention time (HRT) of 1–3 days and AIE concentrations of 10–50% was used in experiments based on a statistical design. Therefore, the effectiveness of a continuous flow bioreactor system (CFBS) in the treatment of AIE using hybrid waste sludge biochar (HWSB) was investigated. Thus, the AIE from these biorefineries requires treatment prior to discharge. Agro-industrial effluent (AIE) from biorefineries that contain high concentrations of COD and color are discharged into the ecosystem. Agro-waste management processes are evolving through the development of novel experimental approaches to understand the mechanisms in reducing their pollution levels efficiently and economically from industrial effluents. ![]()
