  • Fall Into Composting

    Dry leaves, twigs, paper, and branches are powerful sources of carbon for compost piles.

     

    Autumn is finally here, and the leaves are beginning to change colors. Pretty soon, people will be raking bright orange and yellow leaves from their lawns. It’s the perfect time of year to start composting – if you start now, you’ll have finished compost in time for your spring garden and flower beds.

    Compost is an organic material made from recycled green and brown materials (like landscape trimmings and branches). Pile these up in a mound or toss them into a compost drum barrel, and pretty soon you will have a robust soil amendment for your garden. You can find more information on our website about home composting.

    Compost has many benefits for homeowners. It retains soil moisture, which is especially helpful during the summer. It keeps weed growth down, which makes gardening much easier. Compost also provides nutrients to the soil, reducing the need for fertilizers. It even adds carbon to the soil, which directly combats climate change.

  • Managing Food Waste with Bugs

    Black soldier fly larvae

     

    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.”

    See the video below for a closer look at these bugs doing what they do.

  • California Resource Recovery Association: A Culture of Zero Waste

    CalRecycle staff speaking at podiums, speaking to conference members, and an outdoor group photo.

    Since 1974, the nonprofit organization California Resource Recovery Association has been working toward a more sustainable California through promoting product stewardship, waste prevention, and recycling. The group’s annual conference for which we are a sponsor, brings together cities, counties, councilmembers, businesses, nonprofit organizations, and industry professionals to network and discuss environmental issues. Every year, CalRecycle staff and guest speakers offer a cornucopia of information about policies, practices, and studies at comprehensive educational and plenary sessions.

    At this year’s conference, we participated in four panels on topics ranging from e-waste and grants to statewide recycling to educate attendees about upcoming regulations, funding programs, and waste management practices. We even got to meet Ryan Hickman, the 10-year-old mini-mogul who has taken the recycling world by storm by starting his own business at the age of 3! Other speakers included Timothy Bouldry of the International Solid Waste Association, which runs a scholarship program for children living in dumpsites across the world; and Froilan Grate, who is the executive director of GAIA Philippines, which educates and promotes community-based waste management and construction of material recovery facilities.
