Methods Of Disposal Flashcards
Methods (7)
Unregulated
Recycling
Incineration
Recovery
Landfill
Submergence
Trade
Unregulated - what
Dumped in unofficial disposal sites
Unregulated - problems (4)
Damage to ecosystems
Contamination of ground + surface water
Air pollution - burning
Insects, vermin, scavenging animals = air + water borne diseases
Recycling - what (2)
Waste is reprocessed into new products
1% of urban pop (15m) survive by scavenging recyclables
Recycling - good (3)
Less waste disposed
Reduced demand for raw materials = decreases environmental impacts
Priding recyclable products = less energy
Recycling- bad (2)
Requires separate collections
Build new facilities to process the waste
Recovery- what (2)
Selective extraction of disposed materials for a specific next use
Use waste instead of producing new products
Recovery - good (3)
Less landfill
Fewer natural resources exploited
Material ps returned to the economy
Recovery - bad
Informal recycling + processing the materials for reuse or sale = GHG emissions is burned improperly
Landfill GOOD (6)
Proper regulations
Capacity = sealed = recreational usage
Good use of abandoned quarries
Easily managed
Methane = vented = fuel
Relatively safe
Landfill BAD (5)
Ugly + smelly
Attracts vermin, flies and scavenging birds
High transport costs = congestion = air pollution
Leaching
Wind blows = litter
Incineration good (4)
Volume reduced by 90%
Used to produce energy
Reduces toxicity of waste
Inactivate disease agents
Incineration bad (5)
Expensive
Air pollution = co2
Incinerator creates ash = has to be disposed
Capacity limitations
Unpopular with locals
Submergence - what
Illegal dumping of waste in oceans
Submergence (2) - UNITED NATIONS REPORTEDβ¦.
Companies dumped radioactive waste off the coast of Somalia - taking advantage of weak governance
Damages oceans ecosystems
