The valorization of coffee cherry waste through hydrothermal carbonization (HTC) was investigated using various organic and inorganic acid catalysts to produce platform chemicals. This study aimed evaluate the effectiveness these for enhancing reaction rates, improving yields, promoting selectivity. results showed that sulfuric adipic were most effective, each resulting in a 20% increase total yield, demonstrating potential acids as efficient HTC. Other catalysts, such benzoic phenylacetic acid, also promising results, while butyric significantly decreased yield. abundantly produced chemicals sugars, followed by formic levulinic HMF, furfural. These findings highlight valuable resource producing key chemicals, feasibility sustainable approach biomass valorization. emphasizes importance selecting appropriate optimize conversion process maximize extraction environmental economic implications are significant, they can contribute development utilization technologies could transform agricultural into high-value products reducing circular economy.

Biochar, a carbonaceous material prepared from diverse organic waste, has gained substantial attention due to its excellent attributes, like carbon content, CEC, abundant specific surface area, structural characteristics, plant nutrient contribution, water and retention etc. Incorporating biochar the soil system introduces supplementary matter, thereby augmenting comprehensive composition microbial dynamics within ecosystem for long time that completely fit perennial crops cultivated in acid prone areas coffee production. Biochar producing materials are easily accessible production husks pollute river streams generally create environmental pollution. However, as advantages too aged technology solve general fertility problems, there is no research recommendation generated application area specially countries Ethiopia. Therefore, this systematic review attempts gather more available empirical on google scholars by using clearly defined, terms obtain answers question ‘how use nursery media preparations. More than 70 papers written different authors project were searched gets. Through investigation, we obtained critical information may suggest sustainable effects of enhancing improving both productivity coffee, while simultaneously preserving ecological integrity system. Applying enhancement technic boosts physical, chemical, biological contents mitigating greenhouse gas methane emission sequestering stalk systems.
