Study Notes
Solid Environment
- Solid waste is unwanted or useless solid materials generated from residential, industrial and commercial activities.
Sources of Solid Waste
- Waste can be categorized by its origin (domestic, industrial, commercial, construction or institutional) or by its contents (organic material, glass, metal, plastic, paper) or by its hazard potential (toxic, non-toxic, flammable, radioactive, infectious).
Types of Solid Wastes
- Garbage: Strictly animal or vegetable wastes, particularly food preparation products that decompose rapidly.
- Trash: Solid waste that does not decompose (packaging, cans, bottles, building materials).
- Hazardous waste: Waste that is ignitable, corrosive, reactive (explosive), or contains toxic chemicals.
Republic Act No. 9003 (Ecological Solid Waste Management Act of 2000)
- An act providing for an ecological solid waste management program, creating necessary institutional mechanisms and incentives, declaring certain acts prohibited, and providing penalties and appropriating funds.
Importance of Solid Waste Management
- Prevents hazardous outcomes of solid waste.
- Protects people and the environment.
Hazardous Materials
- Can be liquids, solids, gases, or sludges.
- Include cleaning fluids, pesticides, and by-products of manufacturing processes.
Classifications of Hazardous Materials
- Flammable/Combustible: Ignite easily and burn rapidly (butane, propane, hydrogen gas, acetone, gasoline, kerosene).
- Explosive/Reactive: Chemicals that produce sudden release of pressure, gas, and heat (black powder, flash powder, ammonium nitrate).
- Corrosive: Causes visible destruction of or irreversible alterations in tissue (bleach, ammonia, vinegar).
- Toxic: Poisonous when ingested, inhaled or absorbed (mercury, arsenic, petroleum).
Who Produces Hazardous Waste?
- Industrial sources are primary producers, users, and disposers of hazardous substances.
- Hazardous products are found in many household items.
Associated Risks
- No signal word: Non-hazardous.
- Caution or Warning: Mildly to moderately hazardous or toxic, causing temporary adverse health effects (skin irritation, vomiting).
- Poison: Highly toxic, fatal if ingested.
Treatment & Disposal
- Reduce: Modifying industrial production and product formulation to decrease waste.
- Reuse: Repurposing waste from one process/use as raw material for another
- Recycle: Converting waste into new materials.
- Composting: Turning organic waste into a soil conditioner.
- Emissions: Managing the gases produced from waste incineration to prevent air pollution.
- Landfills & Dumps: Traditional waste disposal method, waste compacted and covered with soil.
