The main types of agricultural waste are biological, solid, hazardous and used oil. Each category has different regulations regarding how waste can be disposed of, so it is important for agricultural establishments to understand the different types.
Solid waste includes any type of garbage produced by an agricultural establishment. This category also includes sludge from water treatment plants and any waste materials created during agricultural work. Many states allow land owners to dispose of solid wastes on their own property, as long as it isn't hazardous.
Hazardous wastes are made of materials that are corrosive, explosive or highly flammable. This category also includes chemicals that are dangerous to humans, animals or the environment. Hazardous waste needs to be disposed of correctly by an agricultural establishment. The method of disposal depends on state regulations and the type of material involved.
Used oil is often produced by agricultural machinery. When oil is used repeatedly, it gathers other materials such as water, chemicals or dirt. This reduces its performance, and eventually the oil needs to be replaced. If an agricultural establishment generates large amounts of used oil, it is required to store it in tanks to prevent the oil from leaking into the surrounding environment.
