Finals | U2: Waste Management Flashcards
Classification of Wastes based on Sources
- Residential
- Industrial
- Commercial
- Institutional
- Construction and Demolition
- Municipal Services
Most common residential wastes
Dry non-infectious waste (ex. papers and biodegradables such as leftover foods)
What wastes does the industrial sector produce?
Byproducts that cannot be used anymore (ex. chemical wastes by manufacturers)
Wastes produced by markets
Commercial waste
Ex. of Commercial waste
Pineapple peels
Coconut husks
Fastfood wastes
Commercial vs Residentian waste
Commercial: more waste is being produced (bulk)
Residential: individual waste
What are institutional wastes?
Waste produced by schools, hospitals, laboratories, etc.
Ex. of institutional waste
Needles, bandages, agar for microbiology
What are Construction
and Demolition wastes?
Wastes resulting in debris, cement, pieces of metal
Ex. of municipal services wastes
- Nuclear waste from nuclear powerplants
- Waste from garbage collection
Majority of wastes acc to Global Waste Generation
Organic waste (46%)
Despite contributing majority of waste, why are organic wastes (46%) and paper wastes (17%) not really a problem?
Organic wastes decompose and go back to the earth as nutrients. Papers can also easily disintegrate when cut
If organic and paper wastes are not the main problem, what is/are?
Glass, metal, and plastics whcih are hard to decompose and can clog waterways
Most problematic waste resource
Plastic
What is told by the Waste Generation by Income?
The higher the income of an individual, the more amount of waste they produce. As they purchase more, more waste is generated
MSW
Municipal Solid Waste
Ex. of residual waste
Plastics, papers that can NO longer be recycled
Ex. of special waste
More on hazardous wastes
Recyclable wastes despite being recyclable can become a problem if —
improperly disposed
More waste produced; more economic in nature
Residential
LEGAL BASES OF WASTE MANAGEMENT IN THE PHILIPPINES
- RA 9003: Ecological Solid Waste Management Act of 2000
- RA 6969: Toxic Substances and Hazardous and Nuclear Wastes Control Act of 1990
Role of RA 9003
Control
Create
What does RA 9003 control?
Generation
Storage
Collection
Transfer and transport (Ex. garbage collection = ⬇ Carbon footprint)
Processing
Disposal
What does RA 9003 create?
Mechanisms
Incentives
Funding
Prohibitions
Penalties
Waste Management Heirarchy
Most preferred options:
Avoidance
Reduction
Reuse
Recycling
Recovery
Least preferrd options
Treatment
Safe Disposal
Ex. of AVOIDANCE
Not buying products that will generate waste (Ex. coffee in styrofoam cups)
Ex. REDUCTION
Reducing consumption
Ex. of RECOVERY
Ex. Garbage collection
Where waste is stored, processed, and distributed
Material Recovery Facility
Recovery flow of solid waste (Barangay level)
Compostable Waste –> Composting (MRF) –> Gardens/ Farms
Recyclable Waste –> Sorting Area (MRF) –> Compartmentalized Area for the different types of SW (MRF) –> Junkshops/ Stores/ Factories
Recovery flow of solid waste (Collection by municipality/ city)
Special Waste–> Drop-off Center (MRF) –> Treatment Plant
Non- Recyclable Waste –> Residual Management –> Dumpsite
Role of RA 6969
Regulate hazardous wastes including:
- Nuclear and radioactive
- Pathological
- Chemical
- Infectious
- Pharmaceutical
Type of waste in Black bag
Non-infectious dry waste
Type of waste in Green bag
Non-infectious wet waste (kitchen, dietary etc.)
Type of waste in Yellow bag
Infectious and Pathological waste
Type of waste in Yellow with black band bag
Chemical waste including those w/ heavy metals
Type of waste in Orange
bag
Radioactive waste
Type of waste in Red bag
Sharps and pressurized containers
Reminds everyone to become a mindful consumer
