In my experience of working in waste management, I believe without a stringent rule and public involvement waste management initiatives will be a complete failure. Also, you notice that, in low and middle-income countries there is growing concern about waste management. For inefficient waste management, all the blame can’t be pointed on to the government rather the society as a whole is also responsible. 

Many of you will say that we should shift towards sustainable products then the only question I have “Is currently available sustainable products affordable?” This will not be feasible for everyone rather segregation at source is a much more viable process.

India’s waste generation is a growing concern and is projected to reach a staggering 436 million tonnes by 2050 [1]. To combat overflowing landfills, Waste-to-Energy (WtE) plants are being proposed as a solution, but is this technology the answer or a potential pitfall?

The Allure of WtE: Power from Trash

WtE plants burn non-recyclable waste to generate electricity. Proponents highlight the benefits:

• Energy Production: India faces an ever-increasing demand for electricity. WtE can help bridge the gap by converting waste into a usable resource [2].
• Landfill Diversion: Landfills are reaching capacity and WtE reduces the amount of waste needing disposal.

The Reality Check: Challenges for Waste To Energy in India

However, WtE implementation in India faces significant hurdles:

• Segregation: WtE plants require well-segregated waste to function efficiently. Unfortunately, India struggles with waste segregation at source, leading to mixed waste streams that can damage WtE machinery and reduce efficiency [3].
• Technology Dependence: India often relies on imported WtE technology, making it vulnerable to price fluctuations and technical expertise limitations [4].
• Environmental Impact: Incineration in WtE plants can release harmful pollutants like greenhouse gasses and toxic ash, requiring stringent emission control measures [5].

Data Speaks Volumes for Waste To Energy Plant

• A 2023 study by Down To Earth reported that only 15% of India’s municipal solid waste is suitable for WtE plants due to high moisture content and low calorific value [4].
• There are currently 48 WtE plants in India, but many are under construction or are non-operational due to the challenges mentioned above [3].

The Road Ahead: A Multi-pronged Approach

WtE has the potential to be part of the solution, but it cannot be the sole strategy. India needs a holistic approach that prioritizes:

• Reduction: Public awareness campaigns and incentives to reduce waste generation at the source.
• Improved Segregation: Robust infrastructure and enforcement mechanisms for effective waste segregation.
• Composting: Organic waste, a major component of Indian municipal solid waste, can be composted to create nutrient-rich fertilizer.
• Recycling: Increased investment in recycling infrastructure to divert a significant portion of waste from landfills and WtE plants.

Conclusion: A Balanced Approach is Key

India’s waste crisis demands a multi-faceted solution. While WtE can play a role in managing non-recyclable waste, it should not overshadow the importance of waste reduction, segregation, composting, and recycling. By prioritizing these aspects, India can move towards a more sustainable waste management system.
