Waste treatment and disposal encompasses the engineered processes and systems used to manage solid, liquid, and gaseous wastes to minimize environmental and human health impacts. It includes physical, chemical, and biological treatment methods such as sedimentation, filtration, adsorption, oxidation–reduction, incineration, composting, anaerobic digestion, and advanced thermal or physicochemical processes, often integrated with resource recovery (e.g., energy, nutrients, materials). Disposal refers to the final placement of residuals in landfills, deep-well injection, or other long-term containment systems designed with liners, leachate collection, gas management, and monitoring to control emissions, prevent groundwater contamination, and ensure regulatory compliance.
Certain detergent additives known as aminopolyphosphonates can be transformed into glyphosate and other problematic substances when wastewater is treated.
