A different type of waste is generated at each stage of the construction process. Brick and concrete blocks are produced at the initial stage of demolition of facilities, which will be replaced with a new investment, while old bitumen or track ballast constitutes waste produced after the removal of the road and tracks. The most commonly generated waste types include soil and rubble, rocks and waste from renovation and disassembly of construction facilities and road infrastructure.1 Many of them can be re-used at subsequent stages of conducted works. Removed soil is a valuable material and can be applied for finishing works. Bushes or branches from clearance, which often cannot be avoided, may be used as the biomass fuel or gardening material after so-called chipping, i.e. grinding to produce small parts. Detailed information on the amount of waste may be found in tables at the end of the report.
Waste management on construction sites is regulated by the Waste Management Plan contained in the BIOZ Plan. If hazardous waste is to be generated in the course of works, prior to the commencement of works the contractor must include this in the "Safe Work Performance" Instruction and respond to emergency situations and environmental incidents during their performance. Proper waste management on construction sites and monitoring of potential residuals of hazardous substances is coordinated on an ongoing basis, on the project completion site by laboratories located on its premises.
