Requires contractors in certain large cities to recycle 50% of the waste generated on construction and demolition sites

This bill requires contractors working on qualifying construction or demolition projects in cities with over 1 million residents to recycle at least 50% of the waste generated (by weight), measured after the law takes effect. It applies specifically to projects like multi-unit residential buildings, larger commercial structures, and major demolitions, excluding hazardous materials like asbestos or lead-contaminated waste. Contractors must document compliance within 30 days of project completion and face fines for non-compliance, with a phased approach starting at 25% for projects permitted within one year of enactment. The law aims to reduce landfill use by integrating recycling requirements into existing waste management systems for large urban projects.
