E-Waste Management in India Quiz

Waste Management

• Waste is any substance, whether solid, liquid, or gaseous, for which no use can be found by the organism or system that produces it.
• Waste materials are the residues or leftovers from human activities.
• The amount of waste generated depends on economic development, standard of living, industrialization/urbanization, and population size.
• Traditional rural societies produce less waste compared to modern urban societies, with rural waste being mostly organic.
• Urban waste is often toxic and non-biodegradable.

Sources of Waste

• Domestic waste: Household garbage, spoiled food, vegetable waste, paper, old newspapers, plastic bags, cloth pieces, leftover medicines, broken glass, and metal pieces.
• Industrial and commercial waste: A variety of waste produced from diverse industries, including solid, liquid, and gaseous waste.
• Biomedical waste: Waste from hospitals, pathological labs, clinics, and nursing homes. Includes syringes, needles, cotton soiled with blood, leftover medicines, tablets, gloves, tubes, bottles, and surgically removed body parts/body fluids. Considered highly infectious and toxic.
• Agricultural waste: Plant residue (stalks, dried grass, leaves, husk, etc.), organic, and completely biodegradable.
• Nuclear waste: Waste from nuclear power plants, including traces of uranium, thorium, and other radioactive minerals/metals.
• Mineral waste: Heavy metal residue and toxic metals (lead, cadmium, arsenic, etc.) found in mining and quarrying areas.

Waste Classification

• By State: Solid, liquid, gaseous.
• By Moisture Content: Dry, wet.
• By Harmful Nature: Hazardous (toxic/harmful to humans, animals, plants, and environment/inflammable/corrosive/explosive) or non-hazardous (non-toxic/not harmful). Examples: household waste, municipal waste, construction waste.
• By Degradability: Biodegradable (organic waste, agricultural waste, vegetable waste, kitchen waste, animal waste) or non-biodegradable (synthetic materials like plastic, nylon, thermocol, rayon, etc).

E-Waste

• The electronic industry is a rapidly growing sector in India and worldwide.
• Maharashtra has the highest e-waste generation followed by Tamil Nadu, Andhra Pradesh, Uttar Pradesh, West Bengal, Delhi, Karnataka, Gujarat, Madhya Pradesh, and Punjab.
• Mumbai has the highest e-waste generation followed by Delhi, Bengaluru, Chennai, Kolkata, Ahmedabad, Hyderabad, Pune, Surat, and Nagpur.

Effects of E-Waste

• Lead: Found in circuit boards, glass panels, gaskets. Can damage the nervous & circulatory systems, as well as affect brain development in children.
• Cadmium: Found in chip resistors and semi-conductors. Accumulates in kidneys and liver, leading to neural damage and embryo/foetus malformations.
• Mercury: Found in relays, switches, and circuit boards. Can cause chronic brain damage, respiratory and skin disorders, and bioaccumulation in aquatic organisms (like fish).
• Hexavalent Chromium: Found in galvanized steel plates and decorators. Can cause DNA damage and asthma.
• Plastic waste: Synthetic materials (polyethylene, polyvinyl chloride, polystyrene) used to create plastic. Problem in the environment due to durability and non-biodegradability.

Plastic Waste Management

• Collect plastic waste separately.
• Reduce, reuse, and recycle plastics properly.
• Send collected plastic to recycling units.
• Discourage plastic use and promote paper or cloth bags.
• Develop innovative plastic recycling methods, such as plastic roads.
• Explore alternative substitutes to plastic.

Solid Waste Management

• Collection, transport, processing, recycling, or disposal of waste materials produced by human activities.
• Practices differ in developed/developing countries, urban/rural areas, and for residential/industrial wastes.
• Management of hazardous and institutional waste is the responsibility of local governments, while management of non-hazardous commercial and industrial waste is often the responsibility of the waste generators themselves.

Solid Waste Management Methods

• Landfills: A common waste disposal method involving burying waste in the ground. Can have environmental concerns related to hygiene, sanitation, and pollution.
• Incineration: Burning waste for thermal treatment. Can lead to air pollution, but heat generated can be used to generate electricity. Considered a practical method for disposing of hazardous waste.
• Recycling: The process of recovering value or resources from waste. Includes physical recycling (recycling waste in its original form)and biological recycling (biological composting).

Waste Management Concepts

• Reduce: Reduce the generation of waste by repairing, reusing, and sharing items.
• Reuse: Employ existing materials again and again in the same form.
• Recycle: Reprocessing waste to create usable items.
• Refuse: Reject the use of harmful materials.
• Rethink: Reconsider waste generation practices before discarding items, considering possibilities for reuse or recycling.
• Regulate: Controlling activities to limit waste generation.
• Research: Continuously investigating new approaches to waste reduction and recycling.

Effects of Improper Waste Management

• Unavailability of land: Land where waste is improperly disposed may no longer be suitable for other purposes.
• Land pollution: Toxic materials in improperly disposed waste can contaminate soil.
• Water pollution: Improper disposal can lead to the contamination of water bodies.
• Loss of biodiversity: Toxins can harm organisms, and the destruction of habitats can lead to a decline in biodiversity.
• Social impact: Improper waste disposal in populated areas can lead to poor hygiene, the spread of diseases, and unpleasant odors.

Functional Elements of Solid Waste Management

• Generation: Waste is produced from various activities.
• On-site handling and storage: Waste is prepared, handled, and stored on-site.
• Collection: Waste is gathered from its sources for subsequent processing.
• Transfer and transport: Waste is transported to processing facilities.
• Processing and recovery: Recovery and reuse of valuable materials from waste, and preparation for disposal.
• Disposal: Waste is sent to its final disposal site (landfills, incinerators).

Current Practices in Urban Solid Waste Management

• Collection from streets and households (in community bins).
• Transfer to transfer stations.
• Collection of reusable/recyclable materials by rag pickers.
• Recycling and transporting of collected waste to recycling facilities.
• Final disposal of waste in designated dumping grounds.

Role of Citizens in Waste Management

• Citizens are responsible for minimizing waste by avoiding littering and segregating waste.
• Understanding the effects of waste mismanagement on the environment, their homes, and communities.

Additional Waste Management Practices

• Biodegradable waste segregation for composting.
• Paper waste separation for recycling.
• Collection of reusable/recyclable materials (plastic, cans, metal) from rag pickers for recycling.
• Initiatives like clean-up drives, awareness campaigns, and education in schools/colleges/communities to promote responsible waste management.
