Solid Waste Disposal Methods Quiz

Study Notes

Pulverization Method

The main advantage is the reduction in waste volume, making it easier to manage and dispose of solid waste.
It allows for easier transportation and potential recycling of materials.

Insecticides in Land Filling

Insecticides like DDT can leach into soil and groundwater during landfilling, posing environmental and health risks.
They can persist in the environment, accumulating in ecosystems and potentially impacting wildlife.

Refuse in Land Filling

Refuse decomposes slowly in landfills, generating methane gas and leachate that can contaminate surrounding areas.
Over time, weight from overlying waste compresses lower layers, altering refuse characteristics and affecting decomposition rates.

Demerit of Land Filling

Landfills require large areas of land and can lead to soil and groundwater contamination.
They also contribute to greenhouse gas emissions, particularly methane.

Disposal into Sea

The purpose is to manage large volumes of waste, particularly those that are non-biodegradable or unsuitable for landfilling.
It helps in mitigating pollution on land but raises concerns about oceanic ecosystems.

Demerit of Composting

One demerit is that it can attract pests and vermin if not managed properly.
Improper composting conditions can lead to odor issues and greenhouse gas emissions.

Incineration Method

The main advantage is significant volume reduction of solid waste, often by up to 90%.
It allows for the recovery of energy from waste materials through the combustion process.

Pyrolysis Purpose

Pyrolysis is used to convert organic materials into useful byproducts like biochar, oils, and gases.
It reduces waste volume while also producing energy and raw materials for other uses.

Solid Waste Disposal into Sea

Solid waste undergoes dissolution, degradation, or sedimentation in marine environments, depending on the material's nature.
It can disrupt marine ecosystems and affect marine life through pollution.

Merit of Land Filling

Landfilling can serve as a controlled environment for waste management, providing a systematic approach to waste disposal.
It can be an effective way to reclaim land, with proper management and engineering practices.
