Hazardous Waste in India: Causes, Impact & 5 Easy Ways to Reduce It at Home

Rajkumari Sharma Tankha

A recent study titled “Waste Management in India: Shifting Gears” by ASSOCHAM in collaboration with PwC highlights a worrying trend—hazardous waste generation in India is increasing at a rate of 2–5% annually.

With rapid industrialisation and urbanisation, the country is facing a significant environmental challenge that demands urgent attention from both policymakers and citizens.

Major Sources of Hazardous Waste

The study identifies several industries as key contributors to hazardous waste in India, including:

• Petrochemicals

• Pharmaceuticals

• Pesticides

• Paint and dye manufacturing

• Petroleum and fertilisers

• Asbestos and inorganic chemicals

• General engineering industries

Waste generated from these sectors often contains toxic substances such as heavy metals, cyanides, pesticides, and complex chemical compounds. These materials are not only harmful to the environment but also pose serious risks to human health due to their flammable, reactive, corrosive, and sometimes explosive nature.

Hazardous Waste Statistics in India

According to the report:

• Total hazardous waste generated annually: 7.46 million metric tonnes

• Number of industries involved: 43,936

• Breakdown of waste types:

  • Landfillable waste: 3.41 million MT (46%)

  • Incinerable waste: 0.69 million MT (9%)

  • Recyclable waste: 3.35 million MT (45%)

These figures underline the urgent need for sustainable waste management practices in India.

What Can Individuals Do to Reduce Hazardous Waste?

While industrial reforms are crucial, individuals can also play a significant role in reducing hazardous waste. Here are 5 simple and effective eco-friendly practices you can adopt at home:

1. Avoid Chemical-Based Household Cleaners

Most commercial cleaners contain harmful chemicals that contribute to indoor pollution and environmental damage.

Switch to natural alternatives:

• Vinegar

• Lemon juice

• Baking soda

• Salt

These ingredients are safe, affordable, and equally effective for cleaning floors and surfaces.

2. Use Natural Compost Instead of Chemical Fertilisers

Chemical pesticides and fertilisers degrade soil quality over time and add to hazardous waste.

Better alternatives:

• Make compost using kitchen waste

• Use natural pest repellents like garlic, onion, and mild soap solutions

This not only reduces waste but also promotes healthier soil.

3. Choose Natural Mosquito Repellents

Most commercial mosquito repellents are chemical-heavy and harmful to both health and the environment.

Eco-friendly options:

• Neem oil

• Camphor

• Citronella oil

These natural repellents are effective and reduce chemical exposure at home.

4. Use Natural Methods for Polishing

Furniture polishes and metal cleaners often contain toxic chemicals.

Try these instead:

• Lemon juice and vinegar

• Olive oil mixtures

• Baking soda or salt-vinegar solutions

They are safer for both your home and the environment.

5. Avoid Chemical Drain Cleaners

Drain cleaners are highly toxic and contribute significantly to hazardous waste.

Safer alternatives:

• Use a suction pump to clear clogs

• Prevent blockages using strainers

• Pour boiling water into drains regularly

Prevention is always better—and safer—than chemical solutions.

Conclusion: Small Changes, Big Impact

The rise in hazardous waste in India is a serious environmental issue, but it is not beyond control. While industries must adopt sustainable practices, individual actions can collectively make a big difference.

By switching to natural alternatives and reducing chemical usage at home, we can contribute to a cleaner, safer, and more sustainable future.

Every small step counts—because reducing hazardous waste today means protecting our tomorrow.
