Potential framework for fully resourced of peach pits by multi-recycling approaches.

The yield of peaches worldwide is approximately 21 million tons annually, with peach pits representing 10% of the waste generated, and the disposal of this quantity of biowaste into landfill or combustion is a common practice that has the potential to cause a number of adverse environmental impacts. To explore the utilization of peach pit as a biomass source, nano-catalysis and high-efficiency extraction were used for efficient recycling management. The findings of DSC-TG and Py-GC-MS indicate that the though nano catalyst exerts a minimal impact on the weight loss rate throughout the pyrolysis process, it is potentially able to influence the composition of the pyrolysis product. UPLC/Q-TOF MS results suggest that peach pits were rich in bioactive components, which have potential applications in biomedicines, food additives and bioenergy industries. Concurrently, the peach pits could be efficiently pyrolyzed into high quality biochar (approximately 39% recovery) at 400 °C. Moreover, the produced biochar exhibits a higher capacity for adsorption of the heavy metal Cd when compared with As and Pb. Therefore, suggesting a potential circular economic model for peach production industry.
