Solid Waste Management Overview

Study Notes

Characteristics of Solid Waste

Physical Analysis: Waste is categorized based on size, shape, and density.
Chemical Analysis: Focuses on the chemical composition, including hazardous materials like heavy metals and organic compounds.
Biological Analysis: Examines the presence of microorganisms, which can affect decomposition and disease transmission.

Collection of Solid Waste

Collection Systems: Include curbside pickup, drop-off centers, and centralized collection in urban areas.
Frequency: Varies depending on population density, waste generation rate, and local regulations.
Collection Bins: Strategically placed to ensure accessibility and minimize distance for collection. Design emphasizes durability, ease of handling, and volume capacity.

Disposal of Solid Wastes

Methods: Landfilling, composting, incineration, recycling, and anaerobic digestion are the most common disposal techniques.
Sanitary Landfill: Designed to minimize environmental impact by isolating waste in a controlled environment. Beneficial for managing large volumes of waste but faces concerns regarding long-term environmental risks.
Composting: A natural process that breaks down organic waste, producing nutrient-rich compost. Effective for reducing waste volume but not suitable for all types of waste.
Incineration: High-temperature burning of waste, yielding ash and emissions. Offers volume reduction but requires air pollution control measures and raises concerns about potential toxic substances.
