A classified dustbin, also known as a trash can or waste bin, is a container used for the storage and disposal of waste materials. The term "classified" generally refers to a trash can that has been designed to sort or classify different types of waste materials for more efficient disposal or recycling.

In some cases, classified dustbins may include separate compartments for different types of waste, such as recyclables, food waste, and general trash. This allows for easier sorting and separation of waste materials, which can make recycling and disposal more efficient and environmentally friendly.

Some classified dustbins may also be equipped with sensors or other technology that can help automate waste sorting and disposal. For example, some smart dustbins can use sensors to detect the type of waste being thrown away and sort it accordingly. This technology can help reduce the amount of waste that ends up in landfills and promote more sustainable waste management practices.

Overall, classified dustbins are an important tool in the management of waste materials, helping to reduce pollution and environmental impact while promoting more sustainable and efficient waste management practices.
