Global Waste Management Outlook 2024

GS Paper 3

Syllabus: Environment Conservation

 Context:  Global Waste Management Outlook 2024, published by UNEP and ISWA (International Solid Waste Association), assesses global waste management trends and costs.

Key findings:

1. Municipal solid waste is predicted to grow from 2.3 billion to 3.8 billion tonnes by 2050.
2. The global direct cost of waste management was estimated at USD 252 billion in 2020, expected to nearly double by 2050 without urgent action.
3. Barriers in waste management: Lack of urgency recognition, incomplete data, and climate impact underestimation; Gendered aspects and informal sector undervaluation; Inadequate legislation, weak enforcement, and lack of enabling environment.

Recommendations:

1. UNEP: Redefine waste as a resource
2. By adopting circular economy models, which decouple waste generation from economic growth, there’s potential for a net gain of over USD 108 billion annually by 2050
3. Utilize data and digitalization to enhance the waste management value chain.
4. Replicate and scale up zero waste
5. Implement producer responsibility fees to prioritize waste reduction and prevent greenwashing.
6. Utilize behavioural science to engage people in waste reduction efforts.
7. Harness the expertise of informal waste workers and recognize the influence of women in waste management.

Role of Innovative Waste Management Solutions

1. Recycling Technologies: Advanced recycling technologies, such as chemical recycling, break down waste into its basic components which can be used to produce high-quality raw materials for new products.
2. Robotic Waste Sorting: Artificial intelligence and machine learning are being used to improve waste separation efficiency.
   1. For instance, ZenRobotics has developed a robotic waste sorting system.
3. Biodegradable Materials: The development of biodegradable and compostable materials helps reduce waste generation.
   1. g. Innovations in eco-friendly packaging, such as edible food containers and biodegradable plastics, are gaining traction.
4. Biotechnology: The use of biotechnology, such as the development of fungi-based packaging materials, is on the rise.
5. Circular Economy Principles: The implementation of circular economy principles in waste management keeps materials in use for longer periods, reducing waste generation and promoting resource efficiency.
6. Zero Waste Strategies: The promotion of zero waste strategies helps reduce waste generation and minimize environmental pollution.
7. Smart Solutions: Companies are developing smart solutions for waste management, transforming waste into energy and reusable products.
   1. g. companies like Ecube, and Enevo focus more on technology.
8. Consumer Education: Companies also need to educate end users about sustainable and innovative solutions for waste management. This increases awareness and encourages responsible waste disposal.
9. Government Regulations: Government regulations and policies can encourage the adoption of innovative waste management solutions. These can include incentives for recycling and penalties for improper waste disposal.
10. Collaboration Across Value Chains: Phool, an Indian start-up, collects floral waste from temples and transforms it into charcoal-free incense sticks and biodegradable packaging material.

Importance of Waste-to-energy (WtE):

WtE refers to a group of technologies that convert non-recyclable waste into usable forms of energy, primarily electricity and heat. This is often done through direct combustion using waste incinerators i.e. burning the waste or the production of a combustible fuel from a gas such as methane.

WtE plants play a vital role:

1. Energy generation: Waste-to-energy (WtE) plants contribute to electricity generation by harnessing the calorific value of solid waste.
   • Eg: India has a total installed capacity of over 554MW from WtE plants.
2. Waste reduction: WtE helps in reducing the volume of solid waste, minimizing the burden on landfills and improving overall waste management.
   • Eg: Incineration reduces the volume of waste by up to 90%, aiding in efficient disposal.
3. Remote and rural energy solution: WtE plants can play a crucial role in addressing energy deficits in remote and rural areas. They can produce electricity from waste generated locally, reducing reliance on centralized grids and expensive diesel generators.
   • g.: Biogas plants at the village level supported by the National Biogas programme.
4. Resource utilization: WtE facilities recover valuable resources from waste, such as metals and certain chemicals, promoting resource conservation.
5. Environmental benefits: Properly managed WtE can contribute to reducing methane emissions from landfills, thereby mitigating greenhouse gas effects.

Government Initiatives:

What is Extended Producer Responsibility (EPR)?

 It is a policy approach and environmental strategy that places the responsibility for the entire lifecycle of a product, including its disposal, on the manufacturer or producer rather than on the end consumer or local government.

The fundamental idea behind EPR is to encourage producers to minimize the environmental impact of their products by considering their entire lifecycle, from the design and production phase to the end-of-life phase.

Conclusion:

The key to sustainable waste management lies in a holistic approach. Prioritizing source reduction and waste minimization through awareness campaigns and responsible consumption patterns should be paramount which is also an emphasis under SDG Goal-12.
