Republic Services Inc. is investing $20 million to modernize its single-stream sorting system at its Anaheim, Calif., material recovery facility (MRF).

The investment will feature a new sorting system featuring patented screens and optical detection technology designed by Bulk Handling Systems to improve operations and recovery, the company said in a press release. The system is designed to increase capacity to 50 tons per hour from 20 tons at the CVT Regional Material Recovery Facility.

The system features a comprehensive Supervisory Control and Data Acquisition (SCADA) electrical control package, which provides Republic with advanced capabilities in operating and managing the process.

“These improvements are the first of a two-phased modernization project intended to further advance Republic’s mission to improve the environment and help its customers reach their sustainability goals,” said Jim Ambroso, Republic area president. “The advanced technology will play a critical role in the management of solid waste and recyclables in Southern California.”

The first phase of the two-phase project is scheduled for completion by the end of the year. The second phase should begin in 2012 and will include a complete retooling of the facility’s commercial sorting lines.

The MRF covers more than 250,000 square feet and is permitted to process 6,000 tons per day.
