    Path to Zero Waste

    In orderto facilitate an interactive community engagement process to obtain input into the development of a living Zero Waste Strategic Plan, 16 meetings with public agencies, stakeholder groups, solid waste service providers, three public workshops, presentations to and discussion with the Board and Solid Waste Committee, and three tours were conducted in 2014.  Participants in the community engagement process were instrumental in asking challenging questions, offering suggestions and solutions, and representing the Castro Valley community.  CVSan adopted a goal of Zero Waste (90%+ diversion) by the year 2029.  CVSan’s Zero Waste Strategic Plan may be viewed at

    CVHS student and Environmental Commissioner, Esiason Rodriguez, spearheaded the task of organizing Castro Valley High School’s fourth waste audit held on Saturday, February 7th.  The audit was conducted as part of CVSan’s Green Ribbon Schools Program.  The results of the audit revealed what materials could have been placed in the recycling or organics carts. 

    The CVHS team of 75 high school students from Leadership, the Smart Energy Club, and others, along with two teachers, and CVSan staff took on the challenge to sort through an entire day’s worth of garbage produced by 3,000 CVHS students and staff. 

    The determined and enthusiastic group of students sorted through 91 bags of garbage in one hour!  In this hands-on learning experience, students found out that of 1,729 gallons of garbage generated from CVHS the Friday before, only 21% was actually garbage, and therefore a total of 79% could have gone in the recycling (30%) or organics (49%). 

    The waste audit also showed that CVHS reduced the overall garbage produced on campus by 25% compared to last year’s data!  This is a successful step in the right direction for a school the size of CVHS and a great opportunity for students to determine additional ways to reduce the amount of garbage, organics, and recycling going into the landfill.

    Great job Castro Valley High School for committing to see what’s in the garbage and continuing to reduce waste at school!  

    Below, are a few photos of the day’s activities, including two special volunteers!



    In the photo above (lower right), CVHS Seniors Alejandro Gonzalez and Jenna Sparks have participated in the CVHS Waste Audit for the past four years since they were freshmen!

    In order to make it easier and more convenient for businesses to reduce waste and save money, CVSan is now offering free short training movies online!  The recently published movies from CVSan offer helpful instructional tips in the following areas: Organics, Recycling, Zero Waste, and the 4R Business, 4R Planet Program.

    What is the best way to utilize the training movies?  The short movies (approx. 2 to 3 minutes each) can be used as introductions, tips, or refreshers for your business recycling and/or organics programs.  In CVSan, collection rates for organics cart service are less than the cost of garbage cart service, which can add up to a lot of savings.  So, the more you and your staff know about reducing waste, the better! 

    For more information, and to watch the movies, please visit the CVSan website at  To inquire about CVSan Technical Assistance to reduce waste and cost at your business, please contact CVSan at (510) 537-0757 ext. 112.

    As a part of CVSan’s Green Ribbon Schools Program, on Thursday, December 18th, Castro Valley Adult School completed the first waste audit of the school year.  CVSan staff and the Castro Valley Adult School team of 9 students and 3 teachers had a great time sorting through 1 day’s worth of garbage from the school to see what could actually have been placed in the recycling bin or organics carts. 

    In this hands-on learning experience, students found out of 96.25 gallons of garbage from the day before, only 11% was actual garbage and therefore a total of 89% could have gone in the recycling or organics cart.  The students learned there is still work to be done to educate fellow students, teachers, and staff how to sort their waste on campus.  Last year, Castro Valley Adult School reduced their garbage service by 1 cubic yard and added outdoor recycling, organics, and garbage containers in the campus courtyard.  Nice job Castro Valley Adult School for continuing to reduce your waste at school and keep up the good work!

    Below is a photo of the students who participated in the waste audit.
