Automated Compact Biodigester for Anaerobically Transforming Kitchen Waste to Biogas and Organic Fertilizer: Impact Analysis for Various Sustainable Development Goals

Anaerobic Digestion (AD) technology has emerged as a viable and universally adaptable solution for managing household kitchen waste (KW), with twin benefits of pollution reduction, and at source generation of biogas and organic fertiliser to support three sustainability pillars i.e., economic, environmental, and social. This study is an attempt to implement this technology at household level through “Automated compact biodigester” (ACBD) developed and patented specifically to convert KW into biogas and fertiliser as responsible household KW management that contributes to health and safety, improving quality of life in urban areas, and meeting some of the 17 SDGs. The findings reveal substantial progress, such as poverty reduction through job creation in entire ecosystem of ACBD from fabrication till final scrapping, bolstering economic growth (SDGs 1, 8, 10, 12) by reducing burden of KW management on municipal corporations, enhancing agricultural productivity (SDG 2) via promoting use of ACBD’s effluent as bio fertiliser, advancing renewable energy usage and diminishing reliance on fossil fuels (SDG 7), fostering inclusive education and gender equality (SDGs 4, 5, 9), combating climate change (SDG 13), transforming cities into sustainable and harmonious environments (SDGs 11, 16, 17), and curbing environmental pollution (SDGs 3, 6, 12, 14, 15).
