Round Table Environment Expert Zoom Meeting on “Importance of Circular Economy in Addressing Waste Management Issues”
June 18, 2023 (Sunday, 12 noon - 1 pm)
- Circular economy is an economic system of closed loop which keeps the product, material and services in circulation for as long as possible.
- Earlier the material is used to make product which when they reached end-of-life became waste and were dumped in landfills and were not re-used.
- In circular economy, resources are mined in such a way that they are made into products and reused for as long as possible and then they become waste. This reduces material use, redesigns material, products and services are less resource-intensive and recaptures waste as a resource to manufacture new material.
- Circular economy is based on 7 R’s: Rethink, Reduce, Reuse, Repair, Refurbish, Recover and Recycle. These form the basis to minimize waste and to gain wealth from waste.
- Circular economy is embraced within the sustainable materials approach.
- Benefits include improving security of raw material, boosting economic growth, job creation.
- Circular economy has the potential to address waste management issues, protect environment, reduce impact of climate change, improve economics and elevate social justice.
- The Government of India has brought in the concept of extended producer responsibility (EPR) in waste management. This reduces material consumption, use more of secondary material as much as possible and promotes ecodesign of products.
- Mission LiFE (Lifestyle for Environment) is a mass movement for “mindful and deliberate” use of resources instead of mindless and destructive consumption of resources. There are 75 action points in different sectors.
- Mission LiFE also gels with the circular economy; transition from throwaway culture to circular economy.
- The ultimate aim of circular economy is no waste. Maximum use of this concept will increase quantity of resources and reduce quantity of waste.
- Earlier waste was discarded, then came the term “waste is wealth” and now it is known as “displaced resource”. It is no more considered as waste.
- Bringing the waste into mainstream is circular economy.
- Niti Aayog has focused on 11 end-of-life products/recyclable materials or waste: Municipal Solid Waste and Liquid Waste, Scrap Metal (Ferrous and Non-Ferrous), Lithium Ion (Li-ion) Batteries, solar panels, gypsum, Toxic and Hazardous Industrial Waste, Used Oil Waste, Agriculture Waste, Tyre and Rubber Recycling and End-of-life Vehicles (ELVs).
- Waste generated in the domestic sector needs to be quantified.
- Landfill site should be the last option. Minimum waste should go to landfill site.
- Incineration of waste at high temperature converts waste to air pollution and if dioxides and furans are not checked, they are released in the enviornment.
- Nature-based solutions should be adopted. Attitude needs to be changed.
- We still do not have adequate infrastructure. Waste has to be connected with infrastructure.
- Until the cycles and systems are established, success will not be easy.
- Municipalities need to be strengthened.
- Circular economy has always been ingrained in our Indian culture. We are a conservation-based society and not consumption-based society.
- Revival of this idea is good and that it is pushed by the government is also a very welcome step.
- More important than recycle is to reduce.
- Recycling of industrial waste cannot be handled by the common man. This should be done by producers to their ultimate destruction without damaging the enviornment.
- Consumers should reduce their consumption based on their needs.
- Today, we don’t know how to reuse products. This may be due to lack of vocational training, which used to be imparted earlier.
- All our developmental indexes are consumption-based.
- Recovery of precious materials from e-waste is not as much as is being done in many European countries.
- Waste should be handed over only to authorized waste collector for scientific recycling of waste.
- PET plastic industry in India is estimated to be around 400 million US dollars, according to the National Chemical Laboratory.
- Municipal solid waste is the most serious issue mainly because of lack of segregation.
- All metro cities should have recycling plants. Delhi has no recycling plant for plastic.
- Lack of adequate infrastructure or funding or lack of will/intention could be the reasons for the slow progress.
- The Central Pollution Control Board (CPCB) portal is tracking the complete process of EPR in plastic waste management, which has become mandatory now.
- E-waste and battery waste rules also have provisions for EPR.
- The producers should draw up a complete process of recycling of product after end of life and educate the public about it. This should be mandatorily written on the package.

A new SARS-CoV-2 variant named “EU.1.1” has been detected in the United States. It is an XBB sublineage related to the XBB.1.5 variant and emerged in early June. The EU.1.1 currently accounts for ~2% of COVID cases in the United States. So far, detection of the new variant has not led to increase in hospital admissions. Although it is more transmissible than XBB.1.5, its parent lineage, there are no red flags so far… (Source: Medpage Today, June 27, 2023).
