Waste characterization is a manual process carried beside waste management plants in a process that consists of taking 1 tone from a garbage truck, dividing the sample into 4 parts, mixing them, dividing again into 4 parts and take one of them (250kg) to analyze them manually. This is a process that takes around 3-4 hours to complete the ...
LD50 is the concentration required to produce a lethal effect on 50 percent of the exposed population. Daphnia magna, a good example of a primary member of the food chain, is a small planktonic crustacean, about 0.5 mm (0.020 in) in length, having an LD50 of about 10,000 ppm TDS for a 96-hour exposure.

Turbidity is the cloudiness or haziness of a fluid caused by large numbers of individual particles that are generally invisible to the naked eye, similar to smoke in air. The measurement of turbidity is a key test of both water clarity and water quality. Fluids can contain suspended solid matter consisting of particles of many different sizes.
Airborne particulate matter is a Group 1 carcinogen. [ 6 ] Particulates are the most harmful form (other than ultra-fines) of air pollution [ 7 ] as they can penetrate deep into the lungs and brain from blood streams, causing health problems such as heart disease, lung disease, cancer and preterm birth.

Definition. Food loss and waste occurs at all stages of the food supply chain – production, processing, sales, and consumption. [13][12] Definitions of what constitutes food loss versus food waste or what parts of foods (i.e., inedible parts) exit the food supply chain are considered lost or wasted vary. [12]

A big part of waste management deals with municipal solid waste, which is created by industrial, commercial, and household activity. [4] Waste management practices are not the same across countries (developed and developing nations); regions (urban and rural areas), and residential and industrial sectors can all take different approaches.
