Bay Counties Waste Services (BCWS) of Sunnyvale, CA, retrofitted the Sunnyvale Materials Recovery and Transfer (SMaRT) Station鈥檚 MSW system. The MRF was originally installed in 2009 and the retrofit was completed in May, 2015. The retrofit and phased installation took 6 weeks and was completed by equipment manufacturer, CP Group, of San Diego, CA. 聽The system currently receives approximately 760 tons of MSW, 126 tons of green waste, and 82 tons of residential curbside material per day. BCWS鈥檚 retrofit objective was to increase recovery of containers. 鈥淭he retrofitted system has increased our recovery rates dramatically for all of our commodities while maintaining our material quality,鈥� says Jeff Nabhan, Facilities Manager for BCWS at the SMaRT Station庐.
The results of the retrofit consist of a 65% increase in recovery of organics, 98.8% recovery of previously missed aluminum cans, and 97.9% recovery of previously missed PET. “Major retrofits are often more complex than new projects, clients place a lot of trust in us to get their system running with as little downtime possible,鈥� says Omneya Salem, Senior Manager of Project Management and Engineering, CP Group. 鈥淐onsidering material recovery goals are critical to a client’s economic pro-forma projections, Bay Counties placed a lot of trust in CP’s approach. I’m happy to be part of the team that met and exceeded those initial client expectations,鈥� Salem continues.
The system retrofit consisted of the installation of 2 new CPScreens on the MSW line for the separation of 2D paper, films, and residue from 3D containers and bulky waste. A new MSS CIRRUS optical sorter was installed on the container line for the identification and recovery of PET, HDPE, and other 3 -7 material. The operations interface was improved, and the new CPScreens integrated with the existing MSW line. All new controls were implemented on the container line by CP Group鈥檚 electrical division, Advanced MRF. 聽鈥淚 don鈥檛 think we could have partnered with a better company to complete our retrofit,鈥� says Nabhan. 鈥淔rom the initial planning, to the final testing, CP offered a complete solution to every issue we had. They came up with new ideas that we hadn鈥檛 thought of to improve our system. Hopefully we will get the chance to work with CP in the future with more expansions.鈥�
