Waste Management Concepts and Practices

The video discusses the challenges and impacts of construction waste, emphasizing the importance of proper management to reduce economic losses, improve productivity, and minimize environmental harm. It explains the classification of construction waste into hazardous and non-hazardous categories and outlines strategies for effective waste management, including prevention, recycling, and valorization. The video also highlights the need for a comprehensive waste management plan, involving all stakeholders, to achieve better outcomes in construction projects.
