  • How Recycled Tires Can Save California Roads at Risk of Landslide

    Santa Barbara’s Ortega Ridge Road is no longer in danger of washing away thanks to 80,000 recycled waste tires. Like many paved pathways that curve and bend along with California’s rugged terrain, the ground beneath the road absorbed water in the rainy season - undermining its stability and causing the asphalt to crack, sink, and slide down the hillside. At one point, the road was reduced to just one safe lane.

    Now, thanks to an innovative new road repair technique, Ortega Ridge Road is stable, safe, and a model for what’s possible in areas prone to landslides.

     

     

    A First for California

    With grant assistance and technical guidance from the California Department of Resources Recycling and Recovery (CalRecycle), Santa Barbara County rebuilt Ortega Ridge Road in 2019 using more than 80,000 recycled tires that were shredded and processed into Tire-Derived Aggregate (TDA). The highly permeable fill material allows water to drain through it (unlike conventional soil)– avoiding excess weight that often causes these types of roadways to wash away.

    The Ortega Ridge Road repair was the first infrastructure project in California to use TDA material in this type of civil engineering application.

    CalRecycle Funding Stopped the Cycle of Failure

    Santa Barbara County spent decades on this problem. “We were looking for a solution for this continually failing road,” says Chris Doolittle, an engineer geologist with Santa Barbara County. “It had been failing for 20 years at a minimum.” Over and over again, crews tried the more traditional repair technique of laying down new asphalt – one layer after another - only to watch the road degrade again.

    “We had a good relationship with CalRecycle and determined this site would be a really good candidate for a pilot project,” Doolittle recalls.

    In March of 2018, CalRecycle awarded Santa Barbara County $158,241 in funding from its Tire-Derived Aggregate Grant Program to purchase the recycled tire fill material. Armed with research from the University of California San Diego, which provided engineering data for the project design, CalRecycle worked alongside the county and engineering contractor GHD Services to design and construct a more eco-friendly and long-lasting repair on a 225-foot section of Ortega Ridge Road.

    Tire-derived aggregate, made from 810 tons of California waste tires, was used to backfill a retaining wall composed of large, rock-filled welded wire baskets (called gabions) to replace failed soil and provide lateral support to the reconstructed embankment. The repair resulted in a more permanent repair, saved the county permitting time, money for easements, construction costs and expensive road materials.

    “CalRecycle provided expert support,” notes CalRecycle senior waste management engineer William Heung. “As a result, public works was able to open a safe, stable roadway to the public more quickly and inexpensively than traditional methods, with the environmental benefit of reducing the number of used tires buried in landfills.”

    There’s an Award for That!

    The Ortega Ridge Road repair earned the 2020 Outstanding Local Streets and Road Repair Project award from the County Engineers Association of California (CEAC).

    “What we want is to see something that is out-of-the-box thinking and innovative,” explained CEAC President Rick Tippett, also the director of transportation for Trinity County. “What this award is intended to do is share success, so other agencies will take those ideas back to their communities.”

    Project leaders are hopeful a recognition like this will encourage other local cities and counties to consider the use of TDA and this groundbreaking engineering technique to improve local infrastructure and protect public safety. “We would like to see more of this type of project around the state,” says Heung. “It is a superior alternative material to other products out there and a great use for California’s scrap tires.”

    Longer Lasting Roads with Little Environmental Impact

    Tire-Derived Aggregate is a smart, cost-effective way to repurpose some of the 51 million waste tires that Californians generate every year. Beneficial uses for this material include:

    • Lightweight, permeable backfill that’s lighter than gravel and more permeable than soil
    • A low-cost option to reduce train noise. When placed under tracks, TDA reduces the vibration and noise that is often a nuisance to those living nearby.
    • Retaining wall backfill, particularly in areas prone to landslides. Because of TDA’s lightweight properties, retaining walls can be designed using less reinforcing steel.
    • Landfill gas collection trenches. The high porosity of TDA makes it an excellent material for filling landfill gas collection trenches that transport methane, hydrogen sulfide, and carbon dioxide.

    CalRecycle’s Tire-Derived Aggregate Grant Program supports projects that use recycled waste tires in place of conventional construction materials for civil engineering applications such as retaining wall backfill, landslide stabilization, vibration mitigation, and various landfill uses. The unique engineering properties of shredded waste tires allow for free-draining, lightweight, and typically less expensive solutions for these types of projects.

    • Since 2011, CalRecycle has awarded $5,582,126 in TDA grants to 28 projects statewide.  
    • Grants are funded through a portion of the $1.75 fee consumers pay on each new tire purchased in California.

  • New Statewide Commission Explores Ways to Adapt California Recycling

    In the wake of changing global markets for recyclable materials , California’s new Statewide Commission on Recycling Markets and Curbside Recycling is getting right to work on strategies to help boost waste reduction, reuse, and recycling. Launched virtually on June 24, the commission of 17 representatives of various stakeholder groups will spend the next six months developing policy recommendations to help clean up California’s recycling stream and strengthen markets for recyclable materials.

    “As the fifth largest economy in the world, we not only have a responsibility to be an environmental leader, but we also have an opportunity to change the national and global agenda when it comes to managing materials and resources,” California Secretary for Environmental Protection Jared Blumenfeld told the group of commission members. “While some point to National Sword policies and other import limitations as a ‘crisis,’ for me, it’s really an opportunity to make sure we clean up the global system and reinvest in California.”  

    The Commission Includes Recyclers, Haulers, Environmentalists, Jurisdictions, and More

    The California Department of Resources Recycling and Recovery (CalRecycle) selected the diverse group of commissioners from a pool of applicants representing a wide range of public agencies, private solid waste enterprises, and environmental organizations in large, small, urban, suburban and rural communities throughout California. Giving so many sectors a seat at the table will enable the commission to arrive at solutions that take various priorities and barriers into account.

    A Goal to Transform Waste into Resources

    Over the next six months, the commission will evaluate the current state of recycling in California and recommend policies to reduce contamination in the curbside recycling stream and improve markets for recyclable materials. By January 1, 2021, the commission will offer those policy recommendations to CalRecycle. The goal is to turn more of California’s waste stream into a supply source for California businesses to create new jobs, combat pollution, conserve natural resources, and make California healthier and more sustainable for future generations. 

    The commission will also provide regular feedback on public messaging and educational materials to encourage recycling and minimize the contamination of materials in curbside recycling programs.

    Addressing Domestic Materials Markets and Clearer Recycling Standards

    In addition to approving its charter and organizational structure, commissioners used their initial meeting to select Heidi Sanborn and Richard Valle to serve as chair and vice chair.  

    Sanborn has worked in the materials management industry for nearly 30 years in roles with the California Integrated Waste Management Board (which later became CalRecycle), industry consulting, and as founding director of the California Product Stewardship Council and the National Stewardship Action Council (NSAC).  Sanborn is currently the Executive Director at NSAC.

    Valle has worked in the recycling industry for forty years in roles that include Chairman of Alameda County’s Recycling Board, councilmember for the City of Union City, and CEO of Tri-CED Community Recycling. Valle currently serves as President of the Alameda County Board of Supervisors.

    Both Sanborn and Valle said they look forward to helping California clean up its recycling stream.  

    “I believe this Statewide Recycling Commission will be the forum from which a stronger domestic market for our materials will be born and uniform recycling standards will be created so California residents will have clear direction in their efforts to protect the environment,” said Valle.

    California’s Strategy to Rise from a Recycling Downturn 

    Right now, California is feeling the fallout from a global market disruption as well as declining prices for recycled materials.  

    Historically, about a third of California’s recyclable material was exported to overseas markets as the state largely operated under a “Collect-Sort-Export” model, with some domestic manufacturing, to manage its recyclable materials.

    Exports have been steadily declining since 2011, due in part to changes in foreign import policies that severely limited markets for recycled commodities. These policies, along with competitively lower costs of virgin (raw) materials, have contributed to a dramatic decline in value for some of California’s most commonly exported recyclables. The lack of available markets can sometimes result in potentially recyclable material discarded into California’s already overburdened landfills.

    COVID-19 made these problems worse. When the pandemic hit California, safety concerns translated to heightened demand for single-use plastics such as water bottles, personal protective equipment, and grocery bags. At the same time, the reduction in workers available to accept recyclables or process materials contributed to a decline in recycled feedstock.

    In combination, these global disruptions create a big challenge for California and its recycling industry, but they also provide the state with a new opportunity to innovate a new model that creates green jobs, supports new markets, reduces pollution, and conserves our natural resources.

    What Are the Next Steps?

    CalRecycle will continue to host the online commission meetings as it works to fulfill tasks set out by the California Recycling Market Development Act (AB 1583, Eggman, Chapter 690, Statutes of 2019), signed into law by Governor Gavin Newsom late last year.   

    With the commission expected to provide recommendations by January 1, 2021, its members agreed to meet every first and third Wednesday morning of the month. Its next meeting is scheduled for July 15th from 8:30 a.m. to 12:30 p.m.

    Hunger in California has doubled, and in some counties has tripled, since the state’s Stay-At-Home order went into effect, according to the California Association of Food Banks. A little-known climate law will soon direct supermarkets, food wholesalers, and other food businesses to send millions of meals to local food rescue organizations instead of dumping surplus food in landfills.

    The law’s new requirements come at a crisis moment for the state. “We’ve seen up to three times as many people showing up at our food banks since the coronavirus pandemic first began and overall hunger in the state has gone up 113 percent,” said Communications Director of the Association of Food Banks Lauren Lathan Reid. 
     
    Demand for Donated Food Has Recently Skyrocketed
     
    In communities across the state, the overwhelming demand translates to miles-long lines of cars of cars filled with thousands of people waiting to enter food banks or make their way through pop up, drive-through food distribution lines.
     
    Lathan Reid said the hardest-hit counties include Marin, Mono, Napa, San Francisco, San Mateo, and Sonoma, where food insecurity has tripled since the start of the pandemic. Hunger in Alameda, Los Angeles, and Santa Clara has increased more than 150 percent. 
     
    Cities and counties can help meet this historic surge in demand by proactively implementing local programs to meet the new statewide requirements, which include:
    • Requiring supermarkets, grocery stores, food service providers, food distributors, and food wholesaler vendors to donate their otherwise wasted food to neighbors in need starting January 1, 2022. 
    • Requiring restaurants of a certain size, hotels, health facilities, large venues and events, state agencies with cafeterias, and K-12 schools to donate otherwise wasted food to neighbors in need starting January 1, 2024.

    Lowering Climate Pollutants by Feeding Californians in Need
     
    As the public demand for government to take on climate change grew, Governor Jerry Brown signed SB 1383 (Lara, Chapter 395, Statutes of 2016), a law designed to lower climate super pollutants. The legislation aimed to curtail landfill methane emissions by reducing the amount of food, yard waste, and other organic waste landfilled in California each year. A component of the landmark legislation will redirect good food that is currently being thrown away to Californians who do not have enough to eat. 
     
    “Before COVID-19, one out of every eight Californians and one out of every five children didn’t have enough food to eat,” said Martine Boswell, a CalRecycle environmental scientist who advises communities and businesses on food waste prevention, edible food recovery, and overall food waste management. “That number has now gone up. At the same time that people are going hungry, hundreds of thousands of tons of edible food is annually thrown into the trash and ending up in landfills.”

    Organics Make Up Two-Thirds of Trash Dumped in Landfills
     
    In California, organic waste makes up about two-thirds of what we landfill each year. As these materials decompose without enough oxygen, they create methane, a heat-trapping gas more than 70 times more potent than carbon dioxide, and a major contributor to ground-level ozone and global climate change. 
     
    To reduce landfill methane emissions, SB 1383 requires a 75 percent reduction in organic waste disposal by 2025, as well as actions to ensure 20 percent of currently disposed edible food is redirected to Californians in need. 
     
    The term “edible food” means food intended for human consumption, but it must also meet the food safety requirements of the California Retail Code. 
     
    “This is one-of-a-kind legislation,” said CalRecycle Environmental Program Manager Kyle Pogue. “No other state or country has required this level of food rescue.” 
     
    California Needs Additional Space and Transportation to Rescue More Food
     
    Meeting the edible food rescue requirement of SB 1383 will require California to increase capacity with the state's food recovery network of food banks, pantries, soup kitchens and other food rescue organizations. Funding helps these groups save more food by growing their capacity to collect, transport, store, and distribute more meals to those in need.

    60 Food Recovery Grants Will Bring Millions More Meals to Californians Statewide 
     
    In the last couple of years, CalRecycle has awarded money to more than 60 food recovery projects all over the state through a series of grants. 
     
    “Supporting food rescue programs in California helps provide jobs and nourish communities by giving them the food they need to survive and thrive,” said Boswell. 
     
    CalRecycle’s Food Waste Prevention and Rescue Grant Program is part of California Climate Investments, a statewide initiative that puts billions of Cap-and-Trade dollars to work:
    • Reducing greenhouse gas emissions
    • Strengthening the economy
    • Improving public health and the environment—particularly in disadvantaged communities. 
     
    The program helps organizations establish or expand food rescue and food waste prevention projects to reduce the amount of food being disposed in landfills.
