Environmental and Chemical Processes

Waste treatment is the process of converting hazardous waste into less hazardous or non-hazardous materials. It involves various technologies such as incineration, neutralization, and solidification.

Waste transportation is the process of transporting hazardous waste from one location to another. It involves the use of specialized vehicles and containers designed to prevent the release of contaminants during transport.

Waste disposal is the process of disposing of hazardous waste in a safe and environmentally sound manner. It involves the use of secure landfills, deep well injection, and other technologies designed to prevent the release of contaminants into the environment.

Recycling is the process of reusing or recycling materials. Upcycling is the process of transforming waste materials or unwanted products into new materials or products of better quality or for better environmental value. Downcycling is the process of transforming waste materials or unwanted products into new materials or products of lesser quality or for lesser environmental value. Composting is the process of breaking down organic matter into a nutrient-rich soil amendment.

Waste reduction, waste minimization, and source reduction are all terms used to describe the process of reducing the amount of waste produced. This can be done by reducing the amount of materials used, reusing materials, and recycling materials.

Sedimentation is the process by which suspended solids settle out of water due to gravity, allowing them to be separated from the water.

Phytoremediation is the process of using plants to remove contaminants from the soil. Plants can absorb, accumulate, and degrade contaminants through various mechanisms.

Soil prevention refers to measures taken to prevent soil contamination from occurring in the first place.

Biodegradation is the process by which microorganisms break down contaminants into harmless substances. Biotransformation is the process by which microorganisms convert one type of contaminant into another. Mineralization is the process by which microorganisms convert organic matter into inorganic matter. Humification is the process by which organic matter is converted into humus.

Bioventing is a bioremediation technology that uses air to stimulate the growth of microorganisms that can degrade petroleum hydrocarbons. Air is injected into the soil, which provides oxygen for the microorganisms and helps to volatilize the petroleum hydrocarbons. The volatilized petroleum hydrocarbons are then removed from the soil by a vapor extraction system.

Bioaugmentation is a bioremediation technology that involves adding microorganisms to the soil that are able to degrade chlorinated solvents. The microorganisms use the chlorinated solvents as a food source and break them down into harmless substances.

Solidification/stabilization is a bioremediation technology that involves mixing the contaminated soil with a binder, such as cement or asphalt, to immobilize the contaminants. The binder prevents the contaminants from leaching out of the soil and contaminating groundwater or surface water.

Waste reduction involves taking actions to reduce the amount of waste produced.

Recycling is the process of recovering materials from waste and reusing them in new products, reducing the need for raw materials and minimizing waste.

Water recycling refers to the process of reusing water after it has been used once, typically for non-potable purposes such as irrigation or industrial processes.
