Waste handling, also known as waste management, refers to the discipline of collection, transport, recycling and/or elimination of waste. The term usually refers to materials resulted from human activity, and to minimisation of the adverse effects upon human health, environment, and general apparel of a human habitat. Additionally, waste management also has a goal to save natural resources, by using the recyclable components of products. Waste has many forms of appearance, such as solid, liquid, gaseous, having various properties (that might render them even hazardous), all of them requiring specific treatment methods.
Selective collection of waste refers to usage of various vessels, receptacles such as: waste bins, containers, all being capable to hold and protect the material from contamination or to prevent spilling into the environment. Collection of waste of recyclable materials is done in properly colour-coded recipients.
Recommended colour codes for various waste collection recipients are: orange for plastics, yellow for metals, green for biodegradables, blue for paper and cardboard, brown for glass and electronics, black for non-recyclables. These colour codes might differ from a region to another, it is important to have the bins properly marked.
For municipal waste collection from commercial and industrial sources, containers of 1,1m3 and respectively 4m3 are typically used.
