Construction and Demolition Recycling Plans and Policies: A Model for Local Government Recycling and Waste Reduction

A major opportunity exists for meeting the State’s waste diversion goals by recycling construction and demolition (C&D) debris. Mixed C&D recycling facilities in the state are routinely recovering 60 to 90 percent of all the materials brought to them. Literally hundreds of reuse, recycling, and composting businesses are available to process source-separated materials from C&D throughout the state.

Overview

A major opportunity exists for meeting the State’s waste diversion goals by recycling construction and demolition (C&D) debris. Mixed C&D recycling facilities in the state are routinely recovering 60 to 90 percent of all the materials brought to them. Literally hundreds of reuse, recycling, and composting businesses are available to process source-separated materials from C&D throughout the state. 

The California Integrated Waste Management Board (CIWMB) recognizes the importance of C&D recycling in meeting the State’s 50 percent waste diversion goal. In November 1997, the CIWMB adopted C&D recycling as one of four major initiatives in its strategic plan to achieve the requirements of the California Integrated Waste Management Act of 1989 (AB 939, Sher, Chapter 1095, Statutes of 1989 as amended [IWMA]). 

C&D materials originate in the construction and demolition of buildings, roads, homes, tenant improvements, landscaping, hardscaping (nonorganic materials used in landscaping design), and site clearing activities. This waste stream includes, among other items: concrete, asphalt, soils, gypsum, wood, ferrous and nonferrous metals, brick, corrugated cardboard, soils, trees, shrubs, and many miscellaneous and composite materials. 

Approximately 11.6 percent of solid waste disposed in California is C&D debris. This amounts to more than 4 million tons of waste disposed every year.
