Recognized for diverting more than 26,000 pounds of batteries in 2022, the company is more committed than ever to help educate customers on safe and effective battery recycling habits.


Cal-Waste Recovery Systems, the leader in waste collection and recycling in Northern California, has been recognized for its efforts in diverting more than 26,000 pounds of batteries in 2022 by Call2Recycle, the country’s largest consumer battery stewardship and recycling program.


Sean Finney, Program Manager for Call2Recycle, states, “California Waste Recovery Systems is a recipient of the Call2Recycle Top 100 Leader in Sustainability Award. The annual Leader in Sustainability Award is given to top performing organizations and businesses that demonstrate a notable commitment to battery collection and recycling.”

Cal-Waste is honored to receive this award for stewardship in sustainability and preserving the environment, and the company hopes it will bring more awareness to an ever-increasing need for recycling education, especially as it relates to batteries.


Cal-Waste’s Material Recovery facility (MRF) is an industrial plant that processes single stream recycling; comingled paper, cardboard, plastic, glass, metal, and anything deemed recyclable by Cal-Waste’s MRF’s explicit standards.  The MRF receives truckloads of recycling from waste collection companies from all over Northern California, as well as the recycling that Cal-Waste collects from the communities it serves.  Batteries are arriving to the MRF at a staggering rate in commercial and residential recycling.  The level of battery contamination in the company’s recycling has been so high that Cal-Waste has created a battery collection system in their MRF to handle the high volume of contamination.


Cal-Waste Quality Control Team Member, Rodrigo Acosta, is shown sorting alkaline and lithium batteries that have been mechanically separated in the Materials Recovery Facility.  Rodrigo removes all batteries from other smaller metals and discards them in the blue barrel (shown on the right) to be processed and recycled by Call2Recycle’s stewardship partners.


In 2022, Cal-Waste diverted 26,721 pounds of batteries that would have otherwise gone to the landfill.  This amounted to over 500 pounds of batteries per week, a staggering amount that Cal-Waste hopes to see decrease as waste generators continue to learn about proper recycling habits. Example sentence: With more than 500 pounds of batteries coming into the Cal-Waste MRF each week, the company is committed to helping educate its customers on how to properly dispose of batteries within the counties they serve. The company also works with other suppliers like CalRecycle to continue to petition for better disposal programs for batteries and other hazardous materials.

Cal-Waste is always looking to the best practices to protect and preserve our environment and our communities.  The proper collection and handling of batteries is critical to the preservation of our environment and the overall safety of our communities.  Batteries present hazards when not handled correctly.  Because of lithium batteries’ ability to start fires, Cal-Waste must be extremely vigilant with their collection vehicles and their MRF operations.  Cal-Waste drivers are trained on the potential for fires from batteries being present in recycling and trash loads.  Additionally, a state-of-the-art fire suppression system that’s monitored 24/7 has been installed in Cal-Waste’s MRF to prevent any fires erupting from improperly disposed of batteries.


Sean Finney of Call2Recycle closed his message of recognition stating, “Your involvement with Call2Recycle’s consumer battery recycling program–especially during a global pandemic with logistical and organizational challenges–reflects the virtues of an environmental changemaker.”

Year of Innovation
June, 2020

“We saw the need to grow with the expanding recycling market with some contracts that came up around us,” says Casey Vaccarezza, director of operations. “We reached out to CP a second time to build our second version.”


“It’s a new concept that CP put together,” says Vaccarezza. “We’re happy with the results. It’s something new in the industry.”


The setup helps Cal-Waste with challenges in material recovery and labor, notes Casillas. “You don’t have people on the pre-sort tearing bags or grabbing heavy stuff,” says Vaccarezza. “It separates material right out the gate before it gets to a sorter’s hands where they have to handle something bulky in a bag and not know what’s in that bag.”

A Principled Approach
April, 2020

CP Group recently completed a total system upgrade at Cal-Waste, Galt, California, that involved adding a Primary Auger Screen, a GlassBreaker Screen, an AWScreen, a CPScreenTM, a Scalping Auger Screen and five MSS optical sorters.


Dave Vaccarezza, owner of Cal-Waste says the Primary Auger Screen, “Takes the burden depth down to a much more manageable level and does a great job of spreading everything out so there are no big lumps and clumps.” It also has allowed Cal-Waste to reduce the number of sorters on the presort line from eight to four. Even with the reduction in workforce, the MRF increased its capacity from 11 tons per hour (tph) to 30 tph.


The Scalping Auger Screen further splits the material into homogeneously sized streams. “I think it is working very well there,” Vaccarezza says. To read more, click here.

May 13, 2018

“The U.S. recycling industry is breaking down. Prices for scrap paper and plastic have collapsed, leading local officials across the country to charge residents more to collect recyclables and send some to landfills. Used newspapers, cardboard boxes and plastic bottles are piling up at plants that can’t make a profit processing them for export or domestic markets.” To read more, click here.
