Collection & Processing
The recovery of resources from residues has been one of the key areas of involvement for CalRecovery. Key personnel have designed both labor-intensive and mechanical processes to recover materials and energy from residues. They have assisted public and private sectors in the planning and implementation of programs for both residential and commercial waste generators. The firm’s experience in solid waste collection has ranged from the evaluation of mixed waste and recyclables collection systems and redesign of routes, to technical assessment of curbside collection methods and equipment, and their effect on the quantity and quality of recyclables.
Assistance in curbside collection procurement, City of San Jose, California
CalRecovery assisted the City in the preparation of an RFP and bid documents for the purchase of wheeled refuse carts and recycling bins. A critical part of the RFP process was the definition of recordkeeping and reporting requirements necessary to allow the City to effectively monitor the collection and processing services. CalRecovery analyzed the impact of the program implementation on disposal rates, container sizes, and volume-based user fees; the analysis included developing various types and complexities of analytical models to reflect local conditions and parameters. As part of the work, CalRecovery conducted technical and economic analyses of the various options available to the City, including collection method, container type, and incentives to maximize recycling.
