Cal-Waste believes in providing its local communities with a clean, safe and healthy environment. To aid in that effort, it operates a recycling processing center known as a Materials Recovery Facility, or MRF.
Opened on June 1, 2013, the MRF is helping communities meet a state requirement that 75 percent of all commercial waste is recycled. This unique facility includes our call center, administrative offices, repair and maintenance facility, the MRF system (for sorting recyclables) and a classroom with a viewing gallery.

In late 2019, Cal-Waste will be expanding it’s facility to incorporate a new state-of-the-art MRF to handle more recyclables and make cleaner products from them as required by the stricter standards being imposed by recycling markets.
In The News
‘Tis the season for way more cardboard! During the month of January, Cal-Waste sees a huge influx of cardboard being processed at it’s MRF Facility in Galt due to extensive online shopping during Christmas. CBS Sacramento’s Call Kurtis discussed this on a 2018 televised news segment on Channel 13, featuring our Community Outreach Coordinator MaryBeth Ospital and Chief Operations Officer Jack Fiori.

How It Works
The recycling facility, or MRF, is housed in a 100,000 square-foot tilt-up concrete building on a 6-acre campus in the City of Galt, California. It processes as much as 200 tons of recyclables per day, totaling nearly 65,000 tons per year.
MRF operations include receiving, screening, sorting, baling, marketing and shipping of recyclable materials from both residential and commercial customers. Below is a look at what these processes look like in practice.
Receiving and Screening
In years past, customers were responsible for separating their own recyclables. Now, the Cal-Waste MRF handles the entire process.
Once inside the MRF, all items are deposited onto the concrete floor for initial screening and sorting. The facility sorts 15 commodity types in all, including paper, glass, plastics, metals, and electronics.
While much of the MRF’s operation involves automated, mechanical elements, people are crucial to its success. The facility houses a team of workers who sort and examine incoming materials to make sure no hazardous materials—such as hypodermic needles, household hazardous wastes, scrap metal, bags or plastic wrap—cause damage to the machines or personnel.
Acceptable recyclable items proceed up a conveyor belt, angled at 30 degrees, under a continual mist that reduces the amount of dust that becomes airborne. Gravity also plays a role in the process, as heavier, glass objects crash into a cleaning machine that vacuums off up to 96 percent of the dirt and labels.
After workers hand sort plastics into one of four categories, a 3,000 psi hydraulic ram is used to bale the separated cardboard, newspaper, mixed paper, plastics, tin and aluminum items. On average, Cal-Waste workers are able to sort up to 44 items per minute.
Tin cans are separated along the way by a giant magnet that lifts them off one of the 50 conveyer belts and deposits them into a special container for baling. Aluminum cans are also separated to create their own bales.
Marketing and Shipping
Once baled, all of the recyclable items are stored locally and prepared for sale to national and international brokers. Demand, government policies and restrictions, determine where the recycled commodities go. Currently, Cal-Waste ships to both domestic and foreign recycling processors.
Although the MRF is highly efficient, contamination is a reality that Cal-Waste must deal with. Contamination levels very by community and by program, and varies from 18-42%. Ongoing community outreach and education are critical to the success of reducing these contamination levels, which are on the rise.
The MRF is more than a cutting-edge recycling center. It’s also a place where community members and school children learn about the recycling process and helping the environment.
The facility’s on-site classroom gives Cal-Waste a very special opportunity to team up with area educators and teach students of all ages about the power and process of eco-friendly waste processing and recycling. It’s a program Cal-Waste is proud to provide to the communities it serves, and there’s nothing quite like it in Northern California.
