Question
Divide the wastes generated from your house into biodegradable and non-biodegradable categories. Suggest methods for their disposal.

Answer

Materials having properties that do not breakdown or decay are called Non-biodegradable.Examples include:
• Glass. • Metals. • Plastics. • Electronic devices. • Medical waste. Biodegradable materials are composed of waste from living organisms and the actual plant, animal or another organism when its life ends. Examples of Biodegradable materials often referred to as “bio-waste”, include the following: • Human and animal waste. • Plant products, wood, unwanted paper, unused food waste, leaves, grass clippings, clothes. • Remains from the death of living creatures. Best way to Disposal Non-biodegradable: There are a few methods to help non-biodegradable waste Recycling: Recycling is the process of converting waste materials into reusable objects to prevent waste. The materials from which the items are made can be reprocessed into new products. Recycling such material saves product and it also reduces the amount of manufacture to make new products. It also helps in energy saving and reducing global climate change. Combustion: is a chemical process in which a substance reacts rapidly with oxygen and gives off heat. Waste like plastic and rubber tires can be burned using this combustion process. These make use of the heat energy generated by the combustion & incineration process to electricity. It reduces the demand for non-renewable energy sources. Landfills: Landfill refers the disposal of waste material by burying it.Landfills is extended storage area for non-biodegradable waste. Landfill is an area, which prevent contamination from the waste entering the area surrounding by soil and water and it also helps to reduce odour and pests. Disposal of Hazardous Waste: Hazardous waste is waste that poses substantial or potential threats to public health or the environment. Hazardous waste is waste that is dangerous or potentially harmful to our health or the environment. Hazardous wastes can be liquids, solids, gases, or sludge’s.
  • Ignitability means that the waste can easily catch on fire.
  • Corrosive wastes are acids/ bases that are capable of corroding metal containers.
  • Reactive wastes are unstable under normal conditions. They can cause explosions, when heated.
  • Toxic wastes are potentially harmful when absorbed. They can pollute water if not disposed of properly.

There were lot of organisms A in the crop fields in an area. These organisms used to feed on organisms B also present in the crop fields but which damaged the standing crops. One day some people arrived in the fields and killed all the organisms A so that they could remove their C for making fancy items which were in great demand. Due to large scale killing of A, the population of B increased too much damaging all the crops in the area and causing a famine-like situation. Apart from A, there is another organism D which can also kill and eat B. Name A, B, C and D.
