Study Notes
Types of Solid Wastes
- Solid wastes are non-liquid and non-gaseous, including durable goods, nondurable goods, containers, packaging, food scraps, yard trimmings, and miscellaneous inorganic wastes.
Municipal Solid Waste (MSW)
- MSW is solid waste from residential, commercial, institutional, and industrial sources.
Garbage or Food Waste
- Garbage is the animal and vegetable residue resulting from food preparation, cooking, and serving, and is largely putrescible organic matter and moisture.
Rubbish
- Rubbish consists of old tin cans, newspaper, tires, packaging materials, bottles, yard trimmings, plastics, and so forth, but excludes garbage.
Trash
- Trash is the combustible portion of rubbish.
Waste Generation
- Waste generation = Materials recovered + Discards
Non-Municipal Solid Waste
- Solid wastes from mining, agricultural, and industrial wastes are produced in substantially larger amounts.
Hazardous Waste
- Hazardous waste is ignitable, corrosive, or reactive (explosive) or contains certain concentrations of toxic chemicals specified by the U.S. Environmental Protection Agency (EPA).
Pathogens in Solid Waste
- Human Pathogens: diapers, handkerchiefs, contaminated food, and surgical dressings
- Animal Pathogens: waste from pets
- Soil Pathogens: garden waste
- These pathogens include viruses, bacteria, protozoa, and helminths, and can spread diseases by attracting animals and insects.
Open Dumps
- Open dumps are the old method of solid waste disposal, now illegal due to environmental and health issues.
Sanitary Landfill
- Sanitary landfills are sites where waste is isolated from the environment until it is safe, with solid waste placed in a hole, compacted, and covered with a thin layer of soil daily.
Incineration
- Plastics that are non-biodegradable can be disposed of through incineration, but glass, food wastes, batteries, and other electronic wastes are not incinerated.
Solid Waste Management
- The system consists of storage, collection and transport, processing, and disposal, with materials recovery, composting, recycling, and energy recovery important in processing and disposal.
Reuse of Wastes
- Reuse is the action or practice of using something again, whether for its original purpose (conventional reuse) or to fulfill a different function (creative reuse or repurposing).
Conventional Reuse
- Conventional reuse is where the item is used again for the same function.
New-Life Reuse/Repurpose
- New-life reuse/repurpose is where the item is used for a different function.
Recycling
- Recycling is the process of converting waste materials into new materials and objects, an alternative to "conventional" waste disposal that can save material and help lower greenhouse emissions.
Composting
- Composting is the controlled biological process of turning organic waste into a soil conditioner, producing a nutrient-rich soil additive called compost.
Ecological Solid Waste Management Act of 2000 (RA 9003)
- RA 9003 provides a comprehensive ecological solid waste management program by creating necessary institutional mechanisms and incentives, appropriating funds, declaring certain acts prohibited, and providing penalties in the Philippines.
