A 2005 study by the California EPA indicated that new residential construction comprised about 10% of the C&D waste stream. Most residential construction waste is typically landfilled and effective waste management remains an elusive goal. Guided by the ADOP2T™ model for diffusion of innovation, this paper presents the results of a funded project to accelerate the adoption of waste minimization and pollution prevention (P2/recycling) practices by Illinois home builders. Key elements of the study were the identification of priority materials for recycling, local best management practices, and implementation of a demonstration project. The results of the study indicated that builders recognize the marketing value of being perceived as a “green” builder and reported their willingness to recycle if the process doesn't (a) cost more than traditional landfill fees, (b) increase supervision requirements, or (c) significantly change work procedures for trade partners. These criteria can most easily be satisfied by commingling all waste materials and sorting in a recycling facility. In absence of such facilities, onsite source separation of waste during a demonstration project necessitated some changes to production and management protocols. Implementation of the waste management plan required vigilant monitoring of the recycling procedures.
