Waste sorting is the process by which waste is separated into different elements. Waste sorting can occur manually at the household and collected through curbside collection schemes, or automatically separated in materials recovery facilities or mechanical biological treatment systems. Hand sorting was the first method used in the history of waste sorting.
Waste can also be sorted in a civic amenity site.

“Waste segregation” means dividing waste into dry and wet. Dry waste includes wood and related products, metals and glass. Wet waste typically refers to organic waste usually generated by eating establishments and are heavy in weight due to dampness. Waste can also be segregeconomic concern.

Waste is collected at its source in each area and separated. The way that waste is sorted must reflect local disposal systems. The following categories are common:

Cardboard (including packaging for return to suppliers)


(clear, tinted – no light bulbs or window panes, which belong with residual waste)

Scrap metal
Special/Hazardous waste
Residual waste

Organic waste can also be segregated for disposal:

Leftover food which has had any contact with meat can be collected separately to prevent the spread of bacteria.
Meat and bone can be retrieved by bodies responsible for animal waste.
If other leftovers are sent, for example, to local farmers, they can be sterilized before being fed to the animals.

Peels and scrapings from fruit and vegetables can be composted along with other degradable matter. Other waste can be included for composting, such as cut flowers, corks, coffee grounds, rotting fruit, tea bags, eggshells and nutshells, and paper towels.

Chip pan oil (fryer oil), used fats, vegetable oil and the content of fat filters can be collected by companies able to re-use them. Local authority waste departments can provide relevant addresses. This can be achieved by providing recycling bins.

Waste sorting is the core procedure that follows after the separately collected packaging waste from municipal, commercial and industrial waste collection has reached our recycling facilities. The aim is to minimize the amount of waste from businesses, local authorities and households that ends up in landfill and transform it into valuable resources.

Waste splitting stands at the beginning of the efficient waste treatment process. The unsorted communal waste is separated into different fractions and then moved for further treatment and waste recovery. Using a selective treatment process, fractions high in calorific value are separated off from commercial and industrial waste, creating a marketable product.

Sorted material is then shredded, pressed into tight bales ready to be delivered for reuse or further treatment. Balling presses are used to compress the material and minimize the volume, thus optimizing storage and transportation efficiency. In addition, pressed bales can be wrapped to protect the material from environmental influences, like sun and water and to prevent odor emissions and leachate.

Materials to be recycled are brought to a collection centre or picked up, then sorted, cleaned, and reprocessed into new materials bound for manufacturing. Collection yards are fenced, secured premises equipped with special containers for waste collection.
