The article "Food waste biochar: a sustainable solution for agriculture application and soil–water remediation" by Snigdhendubala Pradhan, Prakash Parthasarathy, Hamish R. Mackey, Tareq Al-Ansari, and Gordon McKay, explores the potential of biochar produced from food waste through pyrolysis as a sustainable agricultural amendment and environmental remediation tool. The review highlights the benefits of biochar in enhancing soil fertility, nutrient and water retention, microbial activity, plant growth, and yield, while also mitigating greenhouse gas (GHG) emissions. The study emphasizes that slow pyrolysis at low to medium temperatures can significantly improve biochar properties, such as carbon content, surface area, cation exchange capacity, and nutrient content, with minimal ash formation. Biochar is also noted for its role in carbon sequestration and its potential to benefit farmers and policymakers. The review identifies knowledge gaps and suggests future research directions to optimize the valorization of food waste into biochar, promoting sustainable practices in agriculture and environmental management.The article "Food waste biochar: a sustainable solution for agriculture application and soil–water remediation" by Snigdhendubala Pradhan, Prakash Parthasarathy, Hamish R.
