Civil Engineering: Solid Waste Management

Solid waste management aims to minimize waste generation, collect and dispose of waste safely, and recycle and reuse waste materials to reduce environmental impact.

Recycling is a process of converting waste materials into new materials and objects, while landfilling, incineration, and composting are methods of waste disposal.

Composting is the process of breaking down organic waste materials by microorganisms into a nutrient-rich soil amendment.

Recycling helps reduce the amount of waste sent to landfills, conserves natural resources, and reduces greenhouse gas emissions. It does not increase the cost of waste disposal.

Resource recovery involves extracting valuable materials from waste, such as metals, plastics, and glass, for reuse or recycling.

Hazardous waste is a type of waste that poses a threat to human health or the environment due to its toxic, corrosive, flammable, or reactive properties.

A sanitary landfill is a facility designed to dispose of solid waste in a safe and environmentally friendly manner, minimizing the risk of contamination to soil, water, and air.

Landfill collection is not a type of waste collection system. Landfills are facilities where solid waste is disposed of, not collected.

Waste-to-energy is the process of converting waste into energy, typically through incineration or anaerobic digestion.

Landfilling is a method of waste disposal, not a treatment technology. Incineration, recycling, and pyrolysis are all waste treatment technologies.

Waste reduction refers to the practices and strategies aimed at minimizing the amount of waste generated at the source.

A transfer station is a facility where waste is temporarily stored before being transported to a landfill or other disposal facility.

Sorting is the process of separating different types of materials from waste, such as paper, plastic, metal, and glass, for recycling or disposal.

Dispose is not a waste management strategy. The 3Rs of waste management are Reduce, Reuse, and Recycle.

Pyrolysis is the process of converting waste into a fuel by heating it in the absence of oxygen.
