India generates over 62 million tonnes of waste yearly, with lower than 60 % collected and solely 20 % handled. As urbanisation accelerates, tens of millions migrate to cities yearly, adopting city existence that drastically enhance waste technology. This development has created an alarming legacy of waste—landfills encroaching upon metropolis borders and rendering huge swaths of land uninhabitable. In the present day, India has over 3,000 legacy waste dumpsites, and projections point out that by 2030, municipal strong waste might attain a staggering 165 million tonnes.
The legacy waste disaster: A mounting problem
Delhi alone struggles with three towering dumpsites—Ghazipur, Bhalswa, and Okhla—and generates greater than 11,000 tonnes of strong waste every single day, in line with an estimate by the Municipal Company of Delhi (MCD). Almost 6,400 tonnes of this waste leads to town’s overburdened landfills. Regardless of a number of authorities initiatives, waste continues to build up and, ultimately, the peak of those landfills continues to develop. As an example, the Ghazipur landfill, operational since 1984, now stands tall at a staggering 65 meters. Makes an attempt to remediate these websites have largely failed as a result of simultaneous addition of contemporary waste.
The environmental and well being affect of those landfills is extreme. Fires brought on by methane emissions are widespread, contributing considerably to air air pollution. Residents dwelling close to these dumps report larger incidences of respiratory illnesses, pores and skin allergy symptoms, and water contamination. Research by organisations such because the Coronary heart Care Basis of India have proven that the air high quality close to these websites comprises hazardous ranges of PM2.5 and PM10, making it troublesome for residents to guide wholesome lives.
Waste-to-energy: A possible game-changer
Globally, waste-to-energy (WTE) expertise has emerged as a promising resolution to the dual issues of waste disposal and vitality technology. By changing non-recyclable waste into electrical energy, warmth, or gas, WTE vegetation scale back the amount of waste and assist mitigate environmental air pollution whereas unlocking the land. Latest studies steered that India can generate 65 GW of vitality yearly from waste.
India has taken preliminary steps in the direction of adopting WTE expertise. Delhi at present operates 4 WTE vegetation that course of round 4,500 tonnes of waste day by day. Nevertheless, the dimensions of operations stays insufficient in comparison with the entire waste generated. Consultants recommend that scaling up WTE vegetation might assist deal with each contemporary waste administration and legacy waste remediation.
Challenges in Implementation
Whereas WTE’s potential is simple, a number of challenges hinder its widespread adoption in India. Establishing WTE vegetation requires important monetary funding, and the expertise calls for common upkeep and expert manpower. Moreover, in contrast to in developed nations, Indian waste has a excessive natural and moisture content material, lowering its calorific worth and making it much less appropriate for combustion-based WTE applied sciences. Furthermore, WTE vegetation, if not operated with stringent controls, can emit dangerous pollution, together with dioxins and furans, elevating environmental and well being considerations.
Socio-economic components additionally play an important position. 1000’s of ragpickers rely upon landfills for his or her livelihood. Any transfer in the direction of mechanised waste processing must account for his or her rehabilitation and alternate employment alternatives.
The best way ahead: A multi-pronged method
A holistic method combining WTE expertise with different waste administration methods is crucial to successfully tackling the legacy waste disaster. Correct waste segregation on the family degree can considerably enhance the effectivity of WTE vegetation. Natural waste may be directed towards biomethanation vegetation to provide bio-CNG, whereas non-recyclable waste can gas WTE vegetation.

Given the excessive natural content material in Indian waste, investing in bio-methanation presents a viable resolution for processing moist waste. Cities like Indore have efficiently carried out decentralised bio-methanation items, which might function a mannequin for different city facilities.
Upgrading present landfills by means of scientific closure and putting in leachate therapy techniques can stop additional environmental degradation. Concurrently, bioremediation strategies might help get better land and scale back landfill peak.
Encouraging non-public sector participation by means of public-private partnerships (PPP) can usher in much-needed funding and technical experience. Profitable PPP fashions in nations like Sweden and Singapore show how collaboration can drive sustainable waste administration. Moreover, selling recycling and composting on the neighborhood degree can scale back the load on landfills. Insurance policies that incentivise waste discount, reuse, and recycling can create a extra sustainable ecosystem.
Turning disaster into alternative
India’s legacy waste disaster presents a formidable problem, but it surely additionally presents a chance to rethink and revolutionise waste administration practices. By leveraging WTE expertise and adopting a complete method to waste segregation, processing, and disposal, India can rework its rubbish dumps into sources of vitality and financial worth.

Cities like Delhi can paved the way by setting formidable targets for landfill remediation and contemporary waste processing. With the suitable coverage framework, technological innovation, and neighborhood participation, the imaginative and prescient of a cleaner, greener India can develop into a actuality. Because the adage goes, the place there may be waste, there may be potential—it’s time to harness it.
