Waste produced during construction may adversely affect the local biosphere. They usually come from demolition and refurbishment works. Their quantity depends on a number of contracts and the level of their progress. We guarantee that waste is removed with utmost care and hazardous waste is appropriately disposed of so that not to pose a threat to people and environment. 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 emergencies 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 investment site by laboratories located there.
A different type of waste is generated at each construction stage. Bricks and concrete waste are produced during demolition of facilities, on the site where a new investment is to be established, while old asphalt or track ballast constitute waste produced after the road and track removal. The most commonly generated waste types include soil and rubble, rocks and waste from renovation and disassembly of construction facilities and road infrastructure. Many of them can be re-used at subsequent stages of conducted works. Removed soil is a valuable raw material that may be applied for finishing works. Bushes or branches from clearance, which often cannot be avoided, may be used as a biomass fuel or gardening material after the so-called chipping, i.e. fine grinding.
Most of waste generated on construction sites may be recycled only in a limited way. Nevertheless, more and more often a lot of waste is used economically (e.g. crushed concrete from demolition may perform a role of aggregate, as well as the removed bituminous mass – crushed asphalt, is 100% re-used, etc.). At the demolition of buildings, metal, wood, glass, rubble, breakstone, etc. may be used.
In turn, Mostostal Kraków activities are mainly related to works using steel and other construction materials. Production starts with the process of the so-called fastening them and forming sub-groups. Next, welding is performed, usually with the MIG method. Finally, the entire structure is subject to finishing processes (e.g. to shot blasting). Waste, mainly steel fragments, dust and mill scale, is generated at various stages of processing.
