This thesis investigates the topic of construction waste management, with a special emphasis on waste disposal strategies after the reconstruction of construction buildings. Waste is defined as a material or product that is no longer needed by the owner, and can be classified according to its aggregate state into gaseous, liquid, sludge and solid, and according to its hazardous properties into dangerous, non-hazardous or inert. The company SANAC d.o.o. from Zagreb successfully applies modern strategies for construction waste management, including separation, recycling and safe waste disposal. SANAC implements systems for sorting materials such as concrete, wood, metal, glass and plastic at the construction site, which facilitates the subsequent recycling process. It uses its own fleet of vehicles to transport waste to specialist recycling centres, ensuring that the materials arrive in good condition. Cooperation with certified recycling centers enables the reuse of materials such as concrete, wood and metal, which reduces the amount of waste in landfills and preserves natural resources.
