Machinex Upgrades West County California Resource Recovery

May 26, 2022 – Machinex is pleased to announce the recent start of a major upgrade at West County Resource Recovery’s municipal single-stream recycling facility, located in Richmond, CA. This project is the result of an effective collaboration between Machinex and its client, Republic Services, to modernize the existing installation in order to increase sorting capacity. This upgrade was specifically designed to address the challenges of the existing building while completely improving the system.

This plant already had an older system designed and installed by another equipment supplier. The client was using around 15 TPH and some of the older equipment was no longer working and as a result had been taken offline. Machinex was asked to upgrade the system to increase processing capacity without increasing the current number of sorters and to eliminate rubber disc screens. Indeed, new system features include a three-tier MACH OCC screen with a fines screen below to remove fines from the system early in the process. The new OCC screen features improved disc spacing and larger shafts to reduce daily cleaning. Two MACH ballistic separators have been installed to handle primary and secondary (finish) 2D/3D separation and, as they have no rubber discs or shafts, they help reduce downtime and maintenance costs. global maintenance. Machinex was chosen for this upgrade due to its ability to supply and deliver a turnkey solution that increases tonnage while having the same number of sorters.

This major upgrade required additional automation to meet this challenge. A MACH Hyspec® double ejection optical sorter has been incorporated to remove both PET (#1) and HDPE (#2) at the start of the container line. A new magnet and eddy current separator were also installed for the recovery of ferrous and non-ferrous metals. The characteristics of this system make it reliable, efficient, flexible, with a limited footprint. The new MRF will be able to process more recyclable materials with a sorting capacity of 22 to 24 tonnes per hour.

Ddesign challenges included working with the existing feed pit as well as setting up a design using the existing baler and storage bunker setup. “We needed two ballistics to achieve the throughput targets set by the customer. We used their existing drum feeder for system power and also reused many of the existing bunkers on the front of the system, such as pre-sort bunkers and commodity bunkers, as these were all of living background bunkers already in place. We had to add a new moving floor bunker for ferrous metals because they didn’t have enough bunkers to accommodate all the salvaged materials. Says Rusty Angel, regional sales manager for Machinex Technologies Inc.

Machinex worked alongside Republic to provide creative design expertise for the renovations. The customers’ requirements were to select a partner who would be able to guide them through this major system upgrade, while providing them with an easy-to-maintain system that could increase the recovery of recyclables.
