C&D Materials Recovery
CalRecovery has worked extensively in the design and evaluation of construction and demolition wastes (C&D) processing, including characterization of C&D wastes; estimating quantities and types of wastes produced by residential, commercial, and industrial C&D projects; identification and securing of markets for recovered materials; development of testing protocols for characterizing wastes produced by C&D contractors; methods of certifying recycling rates of C&D recycling facilities; utilization of waste stream data for planning; design and optimization of processing systems; and economic analyses.
Market study for C&D-derived and drop-off materials (private recycling firm)
CalRecovery performed an analysis of markets for potentially recoverable materials from processing of construction and demolition (C&D) debris and from drop-off of recyclables at a proposed C&D facility in Virginia. The processing capacity of the facility is nominally 250 tons per day. The market analysis provided information that could be used to develop markets for a number of material types targeted for recovery and recycling. Materials included grades of aggregate, paper, aluminum and tin cans, plastics (PET, HDPE), glass containers, wood, gypsum, concrete, and asphalt shingles. The report described the methodology utilized in the study, results of the market contacts and demand, and conclusions and recommendations.
Analysis of C&D processing alternatives, RethinkWaste (previously South Bayside Transfer Station Authority), Redwood City, California
Technical and financial analysis of processing alternatives for C&D debris delivered by self-haulers and by open-top roll-offs to the transfer station. Work included preparation of conceptual processing configurations and estimations of capital and operating costs. Also, strategies to improve diversion of C&D materials (such as wood waste) were recommended, including the use of differential tipping fees for clean loads of materials.
