Biodegradable waste is a type of waste, typically originating from plant or animal sources, which may be broken down by other living organisms. Waste that cannot be broken down by other living organisms may be called non-biodegradable. Biodegradable waste can be commonly found in municipal solid waste (sometimes called biodegradable municipal waste, or BMW) as green waste, food waste, paper waste, and biodegradable plastics. Other biodegradable wastes include human waste, manure, sewage and slaughterhouse waste.
Solid waste is any garbage, sludge, or other trash. Examples are household garbage, scrap metal, old tires, furniture, discarded appliances or cars, used oil, antifreeze, sewage, empty aerosol and paint cans, construction debris. Solid wastes from humans is called feces.
Solid waste refers to materials that are in a solid state, such as paper, plastic, or food scraps, while liquid waste refers to materials in a liquid state, like wastewater or oils. Solid waste is typically easier to manage and transport, while liquid waste may require specialized treatment due to its potential to contaminate water sources.

Yes, ducks do excrete waste. Like other birds, they excrete both solid and liquid waste, which typically comes out as a semi-solid droppings that contain urates, a form of uric acid. This waste is a natural part of their digestive process and is expelled from their bodies through the cloaca. Duck droppings are commonly found in their habitats, especially near water sources.

Improperly disposed waste in landfills can release harmful chemicals and toxins into the soil and groundwater. Littering and illegal dumping of solid waste can contaminate the land and harm wildlife. Industrial activities and mining can lead to the accumulation of toxic substances in the soil. Improper disposal of electronic waste, such as old batteries and appliances, can release hazardous materials into the environment.
Solid waste is eliminated through the anus.
The largest portion of municipal solid waste is typically comprised of organic materials, which include food scraps and yard waste. This category often constitutes around 30-40% of total municipal solid waste, depending on the region and its waste management practices. Other significant contributors include paper and cardboard, plastics, and metals, but organic waste generally leads in volume. Reducing organic waste through composting and other methods is a key focus in waste management initiatives.
Solid waste can be classified into different types depending on their source:a) Household waste is generally classified as municipal waste, b) Industrial waste as hazardous waste, and c) Biomedical waste or hospital waste as infectious waste.
The solid waste produced by sewage is called sludge. It is a semisolid material that contains a mixture of organic and inorganic matter, as well as bacteria and other microorganisms.
The entire digestive system is involved in the production of solid waste, but the rectum is the orifice through which it exits the body. Incidentally, the term "solid waste" also has applications other than those relating to the digestion of food. It often refers to garbage that people throw out.
