Study Notes

Concept of Solid Waste

Solid waste refers to unwanted or discarded materials that are not liquid or gas, originating from various human activities.
Common sources include households, industries, and institutions.

Environmental Impact of Solid Waste Disposal on Land

Contamination of soil and groundwater occurs due to leachate, which is liquid that drains or 'leaches' from waste.
Greenhouse gas emissions, such as methane, result from organic waste decomposition in landfills.
Loss of biodiversity can happen as habitats are altered or destroyed by disposal sites.

Categories of Solid Waste and Their Sources

Municipal Solid Waste (MSW): Generated from residential, commercial, and institutional sources.
Industrial Waste: Produced during manufacturing processes, including by-products and packaging.
Hazardous Waste: Contains toxic substances that can pose risks to health or the environment, such as batteries and chemicals.
Construction and Demolition Waste: Arises from construction activities, including concrete, wood, and metals.

Composition and Characteristics of Solid Waste

Organic Waste: Comprises food scraps and yard waste, typically biodegradable.
Inorganic Waste: Includes metals, plastics, and glass which have slower degradation rates.
Hazardous Waste: Characterized by its potential to harm human health or the environment, often requiring special handling.

Functional Elements of Municipal Solid Waste Management

Collection: Involves gathering waste from generators and transporting it to treatment or disposal sites.
Transportation: Movement of waste using vehicles from collection points to disposal facilities.
Disposal: The final placement of waste, including landfills, incineration, or recycling processes.

Objectives of Solid Waste Management

Protect public health by minimizing exposure to hazards.
Reduce environmental impact of waste disposal methods.
Promote recycling and recovery of materials to reduce the need for raw materials.

Principles of Solid Waste Management

Sustainability: Efforts should meet present needs without compromising future generations.
Integrated Approach: Combining various waste management strategies for efficiency and effectiveness.
Polluter Pays Principle: Those responsible for waste generation are financially accountable for its management.

Hierarchy of Waste Management Options

Waste Reduction: Minimizing waste at the source is the most effective strategy.
Reuse: Encouraging the use of items multiple times before disposal.
Recycling: Transforming waste into new products to extend resource life.
Energy Recovery: Converting waste to energy through various technologies.
Disposal: The least preferred option, involving landfilling or incineration.

Components of Municipal Solid Waste Management

Waste generation and segregation practices.
Collection systems for efficient waste pickup.
Transportation modalities for waste management.
Processing facilities for recycling and recovery.
Landfills and incinerators for ultimate disposal.

Steps in the Development of a Solid Waste Management System

Assessment of current waste generation and management practices.
Development of waste reduction strategies and educational programs.
Design and implementation of efficient collection and transportation systems.
Establishment of treatment and disposal facilities to accommodate waste types.
Monitoring and evaluation processes to ensure effectiveness and compliance.
