Theme: Environmental Science

Summary of the Day:

We began our field day with an introduction to Cal Waste from MaryBeth Ospital. She told the group about the history of the company. Cal Waste is a family owned business who just welcomed the 5th generation into the world a couple weeks ago. Cal Waste is also the largest, locally-owned waste collection and material recovery operation in the region, providing residential, commercial and industrial services to areas throughout Sacramento, Calaveras, Alpine and San Joaquin Counties.

We began our day in the Outreach and Education room at Cal Waste and on the far side of the room was a large window that over looked the MRF, which is the Materials Recovery Facility. This is where all of the recycling and garbage is brought in, processed, and sorted by material type. After our introduction we took a tour of the facilities. The San Joaquin FARMS Leadership students were able to get up close in personal with the trucks, the shop and even get a closer peak into the MRF which is currently be renovated and upgraded to a more technology based system. This new system will allow for the waste being processed to be more thoroughly sorted and cleaned of any contaminated materials.

After our tour we met back in the Outreach and Education room. The group was then met by Dr. Kevin Williams and Dr. Peter Kerr from the California Department of Food and Agriculture. Both Kevin and Peter work in the Plant Pest Diagnostic Center at the CDFA in Sacramento, CA. They presented on Plant Health and Pest Prevention. They also shared with the students some insect displays as well as some pest traps that they use for insect collections.

“They say a picture is like a thousand words. Well looking at a specimen is like looking at 1,000 pictures” – Dr. Kevin Williams, CDFA

After the conclusion of our CDFA presentation we took a lunch break before introducing our next guest speaker, Chris Vicense. Chris is the Equipment Manager at Cal Waste and started with the company when he was 16 years old. He has been with the company for over 25 years and was an inspiring testament to what it is like working or a family owned business. He also spoke to the students about the importance of trade schools and apprenticeships and the different opportunities in which they can get involved at Cal Waste.

Our final speaker for the day was Dave Vaccarezza the Owner of Cal Waste. He shared with the students more insight on the family history of the business and told the students how true the saying is “If you love what you do, you’ll never work a day in your life”. With the MRF currently down for 6 weeks while it is being upgraded, there are 54 employees who are out of jobs. Rather then letting them go and trying to refill positions in 6 weeks Dave found positions as well as made new positions for all of his employees! Thank you Cal Waste for the hospitality and hosting the San Joaquin FARMS Leadership Program for a field day!

Boggs Tract Community Farm is managed by the Puentes organization and their goal at Boggs Tract is to connect the community with the land and help provide them with a space to grow farm fresh produce. We began our day with a tour of the farm by Clifton Maxwell, the Farm Manager. Clifton showed the students the different garden plots that can be rented by the community, the outdoor education area, the chicken coop, compost site, bee hives, and tree nursery. Following our tour Clifton lead the students in different farming activities where the students were able to get their hands dirty and plant seeds, spread mulch and create a new garden bed. The students worked for about an hour and then we took a break for lunch.


Following lunch, the students were introduced to Jessica Bryant. Jessica not only works at Boggs Tract but is also an incubator farmer and leases the land across the street which is where she has her farm Corn Poppy Produce. Jessica provides farm fresh produce to the Stockton community and sells at farmer’s markets, her farm stand, and has also done work with the local culinary program. The FARMS Leadership students helped weed her garden beds, prep beds for new crops, and plant winter crop seeds. This is where we concluded our day in Stockton learning about urban agriculture and getting a lot of hands on experience at Boggs Tract Community Farm.

Cleaning Up The Trash At Cal Waste!

Summary of the Day:

Our final field day of the 2018-2019 program year with the SJ FARMS Leadership Program was a little different this year. We visited and toured Cal Waste and Galt, CA. The FARMS students learned about sustainable management practices and how to be more effective and efficient in their recycling habits.

We began our day in the Outreach and Education room at Cal Waste. We were welcomed by Mary Beth who gave us an introduction to the company and an overview about what Cal Waste is all about. Cal waste is a family owned business and is the largest, locally-owned waste collection and material recovery operation in the region, providing residential, commercial and industrial services to areas throughout Sacramento, Calaveras, Alpine and San Joaquin Counties. On the far side of the room was a large window that over looked the MRF, which is a materials recovery facility. This is where all of the recycling and garbage is brought in, processed, and sorted by material type.

Mary Beth then took us on a tour of the facilities. We were able to check out the different types of vehicles up close. We also toured the mechanic shop where the trucks are worked on and maintained. Then we checked out the MRF from the ground floor. After we finished our toured we headed back to the Outreach and Education room. Cal Waste hosted us for lunch and the students presented their Community Action Projects. These are the projects the students worked on within their school groups to better their community and teach others about what they have been learning about this year in FARMS. After the students were done with lunch and their presentations we played Cal Waste’s versions of jeopardy and bingo to conclude our day!
