Debris is waste from construction and demolition.
The notion of rubble usually refers to debris and stones that result from the demolition, destruction or deterioration of a structure or the development of masonry work . Debris is remains of different materials.
When a building is erected, renovated or demolished, debris is generated. These may be waste materials that are made on the site itself (such as concrete ) or pieces of elements already manufactured previously ( pieces of bricks , ceramic fragments , etc.).
Crushing rubble
Once debris is generated, the need arises to dispose of it. It is common to use a crusher to reduce its size and thus facilitate its disposal or recycling .
The crusher, also known as a crusher in some regions, uses force to break down debris, resulting in smaller pieces. It is possible to differentiate between impact crushers and jaw crushers .
Minimize pollution
There are generally laws and regulations that indicate how to proceed with debris. The aim is, through regulations, to ensure that construction and demolition waste does not end up contaminating natural resources and threatening the health of the population.
When there are no controls and people are not aware of environmental problems, debris usually ends up in vacant lots, green spaces, rivers or even on any corner. In order to combat this contamination , dumpers or landfills authorized by the authorities are usually available for the final disposal of the debris.
Let's take the case of the City of Buenos Aires , the capital of the Argentine Republic . The municipal government established a free debris removal service , which residents can request by telephone or through the Internet . This is to ensure that no one throws debris on public roads.
It is important to clarify that this free collection service is aimed at home works. In addition, there is a limit of up to 500 kilograms of debris per work ; If this amount is exceeded, a specialized company must be hired.
Earthquakes and other disasters can generate tons of debris.
Debris recycling
Beyond landfilling, the current trend is to promote the recycling of rubble . This reduces the level of waste that reaches legal landfills or ends up in illegal places.
In any case, the main advantages of recycling are the ecological benefits (as materials are reused, the need to extract more natural resources is reduced) and economic benefits (the activity encourages the creation of jobs ).
How to recycle
The debris recycling process begins when the waste is transferred to the corresponding plant. Upon arriving at this site , a first selection of the debris is carried out, separating the most voluminous and those that cannot be recycled.
The rubble is then introduced into a drum that allows it to be screened and various separations are successively carried out. Then, after manual classification, crushing is carried out. The resulting products can be reused in the construction industry as aggregates , for example.
