A deceased infant was found on a conveyor belt amid trash and recyclables Friday morning at a waste-sorting facility in San Jose.

Workers called 911 at 3:31 a.m. to report the discovery, which happened at the GreenWaste Recovery facility located at 625 Charles Street, as KPIX reports. Arriving officers, crime scene investigators and members of the Santa Clara Coroner’s Office were all on the scene Friday, and the cause and manner of death has not yet been determined.

GreenWaste is the trash and recycling collector for the San Jose area, much as Recology is for San Francisco. The Charles Street facility appears to be one of two main sorting facilities — described on the company website as its "Dirty MRF" or materials recovery facility, where municipal solid waste from single family homes and multi-family complexes is sorted and separated, with organic materials getting sent for composting.

As the Mercury News explains, this facility "processes residential and commercial waste, as well as recyclable materials." The company says this facility processes 90 tons of waste per hour.

The identity of the child has not yet been determined, and will only be made public if and when the next of kin have been informed.
