Food, energy, and water resources are intricately interconnected, and nexus provides a holistic approach for addressing these complex links to minimize inefficiencies and waste. Nexus approach and circular economy are considered as effective solutions for sustainability. Quantification of these relations is the first step towards incorporating nexus modeling which helps sustainable production and consumption.

Article Synopsis
  • The study investigated the use of Pleurotus ostreatus (PO) fungi to pre-treat a mix of agro-wastes (wheat straw, rice straw, and pearl millet straw) combined with varying percentages of biochar to speed up the pre-treatment process for anaerobic digestion.
  • Results showed that the highest lignin removal (40.4%) occurred in the mixed agro-waste group, significantly improving pre-treatment efficiency compared to untreated samples, while biochar reduced the pre-treatment duration.
  • The combination of these methods led to a 83.33% increase in biomethane yield from spent mushroom substrate, demonstrating the potential for enhanced energy and food production with reduced reliance on single biomass sources.

The exponential generation of municipal solid waste (MSW) and landfill disposal without any treatment has increased the continuous generation of landfill leachate. Improper MSW and leachate management are contributing to environmental degradation and water and soil pollution, which must be treated. Numerous works have been conducted on leachate treatments for energy and resource recovery.
