With the increasing demand for fruits, the waste generated from their production and processing is becoming a significant environmental challenge. A recent review in the Journal of Analytical and Applied Pyrolysis highlights the potential of converting fruit waste into biochar through thermochemical processes like pyrolysis and hydrothermal carbonization. Fruit waste, rich in moisture and nutrients, differs significantly from other biomassBiomass is a complex biological organic or non-organic solid product derived from living or recently living organism and available naturally. Various types of wastes such as animal manure, waste paper, sludge and many industrial wastes are also treated as biomass because like natural biomass these More sources like straw or wood, necessitating specialized methods for biochar production.

The review outlines the key factors influencing the production of high-quality fruit biochar, such as temperature, residence timeResidence time refers to the duration that the biomass is heated during the pyrolysis process. The residence time can influence the properties of the biochar produced.   More, and the composition of the raw materials. Fruit biochar has shown promise in various applications, including as electrode materials for energy storage, catalysts in chemical reactions, and adsorbents for pollution control. Additionally, fruit biochar can be used as a medium for anaerobic fermentation and as a precursor for biosensing materials.

Despite these promising applications, the industrial-scale production of fruit biochar is still limited due to gaps in comprehensive research. The review calls for further studies to optimize production methods and evaluate the full potential of fruit biochar compared to biochar derived from other biomass sources. By addressing these challenges, fruit waste can be transformed into valuable products, reducing environmental impact and contributing to sustainable resource management.
