Effective strategies include: (1) Accurate site planning: Plan waste reduction efforts from the outset, taking into account local waste management regulations and available resources. (2) Assign responsible personnel: Designate specific team members to oversee waste reduction efforts, ensuring they understand their roles and responsibilities. (3) Implement recycling programs: Establish recycling programs for materials such as paper, plastic, and glass. (4) Use correct materials and practices: Only use materials and practices approved for the project, and follow guidelines for environmental protection. (5) Monitor and report waste: Track and report waste generation, identifying areas for improvement and optimizing waste reduction strategies.

1-Prioritize deconstruction over demolition: Where possible, deconstruct instead of demolish existing structures to salvage reusable materials such as bricks, wood, or metal fixtures.

Main root cause for waste generation at construction site is Rework due to modification,plumbing , electrical and elevation as well, excess materials like concrete blend, 10 to 15% of steel material wastage after cutting, the can be controlled by adopting effective waste elimination practices like lean , tpm and effective training to all levels.

Reduzir a geração de resíduos em um projeto de construção é uma medida importante tanto em relação à redução dos impactos ambientais quanto também para diminuição dos custos. Posto isto, algumas estratégias podem ser adotadas no intuito de reduzir a geração de resíduos, como: - Implementar de sistemas de separação e reciclagem dos resíduos; - Reutilizar materiais de outras obras ou peças de madeira e metal, por exemplo; - Supervisionar as atividades construtivas para garantir o correto gerenciamento dos resíduos gerados; - Assegurar que os materiais que não possam ser reciclados e reutilizados sejam destinados corretamente.

Start by planning for minimal waste from the design phase, using durable, reusable, or recyclable materials. Ensure accurate measurements and precise cutting to minimize off-cuts and surplus materials. Implement a just-in-time delivery system to reduce material overstocking and prevent storage-related waste. Promote modular or prefabricated components to streamline assembly and minimize on-site waste. Establish a waste sorting and recycling program on-site, ensuring materials like metals, plastics, and concrete are appropriately separated for recycling. Train workers on sustainable practices and monitor waste regularly to identify areas for improvement and optimize resource use.
