Yuba County is home to the latest construction project to use recycled waste tires to patch up damaged roadways. Last month, 430,000 tires were utilized as filling material to repair multiple roads destroyed by recent landslides.
CalRecycle awarded the county $439,636 as part of the Tire-Derived Aggregate Grant Program, which funded both the purchase of the recycled tire material and the repair work.
Tire-Derived Aggregate (TDA) is made from shredded scrap tires and is used in a wide range of construction projects. These uses include retaining wall backfill, lightweight embankment fill, landslide stabilization, vibration mitigation, and various landfill applications.
The material is lightweight and cost-effective, and it drains well in wet conditions.
As an added bonus, recycling tires diverts them from landfills and illegal dumpsites. Currently, California generates more than 40 million waste tires per year.

On the UC Davis campus, a group of researchers is breeding lots of bugs. I mean, a lot.
“At any given time, we could have a million flies,” said Trevor Fowles, a graduate student in the Department of Entomology and Nematology.
The university researchers are exploring how to use black soldier fly larvae to break down organic waste—like almonds, wine waste, and tomatoes—and convert it into useful products.
“Fats from the soldier fly can be converted into machine lubricant and oils that you can put into animal feeds,” Fowles said. “Their frass (powdery white refuse) is rich in nutrients and can be added to composting operations.”
With SB 1383 requiring 50 percent reduction in the level of organice waste by next year and a 75 percent reduction by 2025, these little flies might end up playing a key role in greenhouse gas reduction.
“We need to keep these foods out of the landfills and reduce our carbon footprint,” Fowles said. “The black soldier flies are just one way we can eliminate this type of waste.”
In July, Fowles and a group of partners started their own business called Biomilitus, hoping to take the black soldier fly concept to businesses throughout the state.
“It (fly larvae) would be interesting to commodities groups who are trying to deal with their waste and trying to make an eco-friendly product,” Fowles said. “So, the almond board and tomato growers, they would be more interested if we had an insect that’s specifically bred to handle their waste products.”

When CalRecycle staffers met up for the recent annual summer picnics, it was not all about the food and fun. Bragging rights were also up for grab between the Sacramento and Southern California employees.
This was all about the zero waste competition to see which group of CalRecycle staffers created less waste at their picnic event.
The social committees and zero waste team coordinated the competition, asking attendees to bring their reusable plates, utensils, and cups. Those who forgot to bring those items were able the rent a mess kit for $1.
Each picnic event had stations for waste, compost, and recycling. Food waste was composted, excess food was donated to a local charity, and cans and plastic bottles were recycled.
The remaining waste was weighed and divided by the number of attendees to come up with a comparable metric for the two picnics: per capita disposal, or the amount of waste per person.
Now, on to the results. With a total of .011 lbs. of waste per person, the winner of the 2019 competition was … Southern California!
Sacramento came oh-so-close with .013 lbs. of waste per person.
In all, CalRecycle staff diverted 91.9 lbs. of waste from this year’s annual picnics, which is a major reduction from the 2018 total of 139.9 lbs. So, in many ways, everyone who participated was truly a winner.
