Solid Waste Management (EXAM PART 1) Flashcards
Solid waste management process
(CTRPD)
collection
transportation
recovery
processing- anaerobic digester, compost, incineration
disposal- sanitary landfill
Municipal solid waste does not include (IAS)
- industrial wastes,
- agricultural wastes, and
- sewage sludge.
TYPES OF SOLID WASTE (DBCIR)
Domestic hazardous waste & toxic waste: medication
Biodegradable waste:
Composite wastes:
Inert waste:
Recyclable material:
TYPES OF SOLID WASTE
Depending upon the source, they are classified as: (HST)
1) House refuse
2) Street refuse
3) Trade refuse
SOURCES of SOLID WASTE (RICICABE)
residential -food waste
industrial- packaging waste
commercial- thin and thick plastics
institutional- wood, paper
Construction and demolition - steel materials
agriculture- spoiled food
biomedical - syringes
ewaste- tv transistor

Advantages of solid waste management: (CFRPB)
- The sites appeared clean and attractive.
- The environment looks fresh.
- It can be recycled to get a new model of usable products like toys.
- It prevents the pollution of water resources.
- It prevents from blocking of water of the irrigational structure like a canal, drain, etc.
Disadvantages of solid waste management (EST)
- It is expensive to manage solid waste as it requires transportation,labor charge as well as pots to collect solid waste.
- It consumes space of the cities as solid waste collector pots.
- It is time-consuming for the safe disposal of solid waste management.

Methods of Waste Disposal (LICSR)
Landfills- Strict regulatory restrictions and high environmental and economic costs
* Incineration- Strict regulatory restrictions and high environmental and economic costs
* Composting
* Source reduction
* Recycling
Advantages landfill (IR)
- Serves to improve/reclaim poor quality land
- Raises the ground elevation. Completed landfills have been converted to municipal parks, play grounds, golf courses, community land use project
Disadvantages of landfill (SSPDP)
- Difficult to find suitable site within
economically feasible distance - It is not possible to build a
completely safe and secure SW
landfill. Some of the pollutants may
escape in the environment in the
form of leachate. - Potential harm to public health due
to air, soil, water and noise pollution. - Damage to local ecosystem.
- Public oppose
INCINERATION pros (RH)
Pros:
* Reduce volume 90%, weight 75%
* Heat from burning converted to electricity
incineration cons (ACC)
Cons:
* Create air pollution
* Concentrates toxins in ash
* More costly than landfills, as long as space available
