[8] Caroll Mortensen was the first director of CalRecycle appointed by Governor Edmund G. Brown Jr. in October 2011, confirmed unanimously by the state senate in May 2012, and served until July 2015.

[12] Director Smithline was appointed by Governor Edmund G. Brown Jr. and confirmed unanimously by the state senate in July 2015.

[15] Ken DeRosa is current chief deputy director of CalRecycle and was appointed by Governor Edmund G. Brown Jr. in November 2012.

[17] When the CIWMB was established, California diverted only 10 percent of solid waste out of landfills and into recycling and/or reuse projects.

The CIWMB's cooperative efforts with California's local jurisdictions (counties and municipalities) in furtherance of AB 939's mandate to reach 50 percent waste diversion contributed to the rise.

[citation needed] The CIWMB worked to implement programs to seek "a higher and better use" for an estimated 92 million tons of waste generated each year in California.

Specifically, the CIWMB provided grants and loans that helped California's recycling industry; used incentive grants and loans to help spur the private sector into developing new markets for recycled materials; cleaned up solid waste disposal sites; and cleared illegal waste tire disposal sites.

[18] By 2017, the recycling rates for bottles and cans in California had fallen to their lowest point in almost a decade, and critics alleged CalRecycle was not sufficiently adjusting its subsidiary processing payments to changing market conditions.

This regulation was adopted as a means of implementing the provisions of the California Waste Management Act of 1989 relating to composting.

The regulations prohibit the composting of unprocessed mammalian tissue unless used for researching pathogen reduction,[5] treated or untreated medical waste, and hazardous waste, and require minimization of odor, impacts, litter, noise, dust, and pathogens, as well as emissions of the permitted facilities.
