Gas waste
Causing Injury or death when Inhaled or Ingested.
Toxic
Can easily ignite and burn rapidly
Flammable
Can burn skin on contact and can erode away surface of materials

Contamination of water bodies and can cause harm to various aquatic creatures that depend on proper water conditions.
Water pollution
Happens when soil is stripped of its fertility and nutrition and caused by chemical such as pesticides and Insectisides.
Soil pollution
Occurs when metals such as thorium, radon, and radium release energy In the environment to achieve a more stable form.
Radioactive Pollution
Caused by poisonious gases and particulate matter In the air.
Air pollution
caused by a rise In environment temperatures
Thermal pollution
Caused by the Introduction of contaminants Into the environment.
Pollution
Involves the recovery and reprocessing of materials from products after they have been used by consumers.
Recycling
A diagram which can guide homes, schools, and communities, in making decisions regarding effective waste reduction and management.
Waste Hierarchy
Uses combustion or burning of wastes to recover energy and reduce the amount of wastes going to disposal
Incineration
A natural process of recycling decomposed organic materials Into rich fertile soils known as composts.
Composting
Dumping of waste In a designated area.
Landfill
• Known as Solid Waste Management Act of 2003
• This law aims to protect the public’s health and the environment through proper waste disposal and environment-friendly methods In utilizing our resources.
Republic Act 9003
The wastes from residential areas are commonly disposed of by the local government and sometimes referred to as
