Construction or Demolition Waste or Rubble is the waste resulting from the construction or demolition of a building, regardless of its characteristics. In the Northeast of Brazil, the term shrapnel is used and in the South of Brazil, they use the term caliça. Waste recycling by the construction industry has been consolidating itself as an important practice for sustainability, either by mitigating the environmental impact generated by the sector or reducing costs. Civil construction waste is significant in the volume of waste in cities. In São Paulo (city), for example, 55% of the waste is produced by civil construction. A waste management (waste management plan) is essential during construction, where materials are separated and sent for recycling. This initiative reduces the production of waste to be deposited in landfills.

Classification of rubble

Construction waste is classified into 4 categories: A, B, C and D. Class A: masonry, concrete, mortar and soil - can be reused in the form of aggregates; Class B: wood, metal, plastic, paper, cardboard, plaster, [glass] waste - can be reused at the construction site or sent for recycling; Class C: waste without recycling technology; Class D: hazardous waste, such as paints, solvents, oils and others, or those contaminated from works in radiological clinics, hospitals, industrial facilities, etc. Construction waste in large quantities can be reused or recycled.

Plan for the Prevention and Management of Construction and Demolition Waste

In Portugal, in the execution of works it is necessary that the execution project is accompanied by a transversal plan called Plan for the Prevention and Management of Construction and Demolition Waste (PPG RCD). It must be included in the PPG RCD: The summary characterization of the work to be carried out, with a description of the construction methods to be used; The methodology for the incorporation of recycled CDW (Construction and Demolition Waste); The CDW prevention methodology, with identification and estimation of materials and reuse in the work itself or in other destinations; The reference to the methods of packaging and sorting CDW in the work or place assigned to it; Estimation of the CDW to be produced, the fraction to be recycled or subjected to other forms of recovery, as well as the amount to be disposed of, with identification of the respective code from the European Waste List.
