Study Notes

Wastes

Wastes are any material, substance, or by-product that is eliminated or discarded as no longer useful or required after a process.
They can be solid, liquid, or gas.
All human activities generate waste.
Developed countries generate more waste than developing countries.
Developing countries face challenges in waste management.

Pollution

Pollution is the introduction of harmful materials into the environment.

Waste Classification

Municipal Solid Waste (MSW): waste from households, businesses, and commercial establishments. Key components include food waste, plastics, metals, glass, and small amounts of construction and hazardous waste.
Industrial Solid Waste: byproducts of manufacturing industries, encompasses materials like paper, packaging, waste from food processing, rubber, leather, and wood.
Agricultural Waste and Residue: agricultural crop residues and agro-industrial by-products, like animal waste, husks, and straws.
Hazardous Waste: toxic waste from industrial, agricultural, manufacturing, nuclear, hospitals, and healthcare facilities. Contains chemical, petrochemical, petroleum, metals, wood treatment, solvents, dry cleaners, pesticides, and herbicides.

Wastewater (Sewage)

Also known as sewage water or dirty water.
Includes human waste, food scraps, oils, soaps, and chemicals. Home wastewater includes water from sinks, showers, bathtubs, toilets, washing machines and dishwashers.

Waste Management

Aims to manage and dispose of wastes. Methods include discarding, destroying, processing, recycling, reusing, or controlling waste.
The goal is to reduce the amount of unusable materials and prevent potential health and environmental hazards.
Methods include waste reduction, landfill dumping, recycling, incineration, composting, and sewage treatment.
In 2016, humanity produced 2.01 billion tonnes of waste, an amount expected to increase by 70% in the next 30 years.

Problems from Improper Waste Management

Landslides: waste dumps collapsing.
Water contamination: water supplies becoming polluted.
Flooding: clogged drains causing flooding.
Disease transmission: spreading illness.
Respiratory problems: exposure to air pollution from incineration.
Biodiversity loss: negative impact on ecosystems.
Decline in tourism: damaged landscapes negatively affects tourism.
Climate change contribution: waste contributes to greenhouse gas emissions.
Threat to food sources: contaminated land and water impacting food production

Microplastics

Tiny plastic particles (smaller than 5mm).
Annually, 100,000 marine creatures die due to microplastic pollution.
1.2 million tonnes of microplastic waste is generated yearly.
Difficult to clean up.
Enters the human food chain through contaminated marine creatures.
