Eco-innovations and sustainability in solid waste management: An indian upfront in technological, organizational,...

Technological interventions and eco-innovative solutions are necessary to cope with the adverse environmental impacts of waste accumulation. The notion to consider "waste as a resource and recycling of the same for getting the value of the waste" has truly transformed the approach towards solid waste management (SWM). Technological eco-innovations rely on the automation of waste segregation, collection, route optimization, digital apps for creating communication (enhanced efficiency by 40-85%) and treatment technologies. The regulatory framework with amendments in rules, new policies, schemes, smart city missions are responsible for the implementation of "Tech-innovations" at the ground level and has shown societal benefits. India has significantly shown progress in sustainable development goals (SDGs) score from 50.93 to 60.23 (year 2000-2019). The innovative and sustainable waste management practices in India have increased contribution to renewable energy (approx. 2554 MW/annum), 15-billion-USD business opportunity by the circular economy, 25-30% resale profit from processed E-waste, increased co-operative collaborations, trailblazing start-ups, improved SDG 3,7,8,9,11,12,13, improved market for green products and services, brilliant institutional and regional innovations addressing the issue of climate change. The present article critically reviews the exemplary eco-innovations (technological and non-technological) including resource recovery and viable technologies for SWM in India. The review also illustrates the lacunae (in awareness, bioproducts adoption and advanced technologies), recommendations based on findings and future research areas. The paper can also assist researchers, entrepreneurs and the policy makers for improving the status of SWM in India as well as other developing countries with the same societal and economic status.
