New project aims to use farm waste to fuel bioeconomy
UC ANR to help create database, support technology for sustainable bioproducts and biofuels
In California's Northern San Joaquin Valley, crop leftovers such as almond shells, fruit peels and orchard trimmings can potentially be converted into sustainable bioproducts and biofuels – with the right technology. The philanthropy Schmidt Sciences' Virtual Institute on Feedstocks of the Future, which supports replacing fossil feedstocks with renewable biomass sources, has awarded new funding to a group investigating how to make better use of the diverse agricultural waste in the region.
“This is an important project for California as it quantifies the diverse ‘ingredients' in the North San Joaquin Valley available to fuel the emerging biomanufacturing industry in the state,” said Gabe Youtsey, chief innovation officer for the University of California Agriculture and Natural Resources. “This foundational work will kickstart a completely new innovation bioeconomy in the Central Valley that will create new high-paying jobs for our communities and support a resilient food and agriculture industry through circular biomanufacturing.”
Circular biomanufacturing is a process that uses waste streams as raw materials to create new products.
“Circular means taking waste streams from agriculture such as almond shells or grape pomace, forest waste or food processing waste and using that material as the ‘feedstock' in a fermentation tank to create new bioproducts,” Youtsey explained.
The group, “Building the Circular Bioeconomy in the North San Joaquin Valley” or BioCircular Valley, is co-led by the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab), UC Berkeley, and BEAM Circular, with partners at UC Merced, UC Agriculture and Natural Resources, the Almond Board of California and USDA Agricultural Research Station in Albany.
“California has this incredible diversity of materials, but they aren't well understood – and this makes it difficult to know how to extract the most value out of them,” said Corinne Scown, a senior scientist at Berkeley Lab and UC Berkeley and one of the project leads. “We want to characterize them and make that information available so companies can more easily figure out which feedstock is a good match for them, and then use that agricultural residue to make everything from bio-based polymers and chemicals to sustainable materials and aviation fuels.”
One of the group's goals is to build a publicly accessible database and user-friendly map full of information about different feedstocks, the raw plant materials and biomass that can be broken down and used to make bioproducts. That includes where feedstocks are located, when they are available, how they are currently disposed of, how they perform in different bioreactors, how much sugar or lignin they contain, whether they can be processed with other feedstocks, their greenhouse gas footprint, the potential cost, and much more.
UC ANR's role is to collect data on available feedstocks from forest, agricultural and food processing byproducts, as well as municipal waste streams through sampling and observation.
“We will do this through the extensive knowledge and relationships we have with the California agriculture industry in the North San Joaquin Valley,” Youtsey said. “UC ANR will also support industry outreach as new ‘conversion' technologies are developed, to pilot them with California growers and processors.”
The project will also test ways to improve the flexibility of the conversion process, which breaks down feedstocks to prepare them to make bioproducts. Researchers will apply artificial intelligence to their lab-generated data to improve predictions of how feedstocks can be processed most efficiently or blended together. Being able to use the same technique on different (or mixed) kinds of plant matter would open up ways for companies to make bioproducts more easily.
“Our region has a fantastic combination of diverse and large-scale agricultural activities alongside manufacturing expertise, making this a great place to scale up bioeconomy innovation,” said Karen Warner, CEO of BEAM Circular. “This project will allow us to reduce barriers to using our region's abundant waste streams in more sustainable and valuable ways, so that we can create the products that people need with renewable inputs that are better for the planet.”
The project builds on ongoing efforts to establish biomanufacturing capabilities in the northern San Joaquin Valley, which includes San Joaquin, Stanislaus and Merced counties. Providing better data on how to convert the valley's millions of tons of agricultural waste into valuable products may spur biomanufacturing companies to build facilities nearby, minimizing how far the raw materials have to be moved and generating new jobs.
“This project is designed to benefit a region that has massive potential, but so far has been economically left behind, and to develop a new industry that can provide improvements in air quality, water quality and greenhouse gas emissions as well as significant opportunities in economic equity and the creation of new jobs,” said Blake Simmons, director of Berkeley Lab's Biological Systems and Engineering Division and the BioCircular Valley project lead.
“This kind of research started as basic science, and now we're bringing information and solutions to people who can use them. And the knowledge generated through this project will advance not only the ability of the NSJV to make use of its own regionally available future feedstocks, but will also accelerate the understanding of feedstocks relevant across California and across the U.S.”
The new funds for the project come from the Virtual Institute on Feedstocks of the Future, a partnership between Schmidt Sciences and the Foundation for Food & Agriculture that supports collaboration on research to transform biomass into alternative feedstocks for biomanufacturing. The award is one of five announced today, which total $47.3 million over five years. It is expected that the five teams will collaborate to share best practices and knowledge to boost the bioeconomy at the national level.
“We are grateful for Schmidt's generous support that will help deploy advanced technologies on the ground,” said Alicia Chang, interim president of Berkeley Lab Foundation. “The foundational research and expertise developed through work for the Department of Energy sets the stage for this team to apply their capabilities to bring jobs and lift the community and the economy in the Northern San Joaquin Valley.”

Food waste, nutrition in prison focus of webinars Feb. 22, 29
Free webinars about food waste and nutrition in correctional systems will be presented by the University of California Agriculture and Natural Resources.
The UC ANR Sustainable Food Systems Emerging Issues Webinar Serieswill first cover food waste on Feb. 22.
“The Sustainable Food Systems strategic initiative panel aimed to highlight innovative solutions to emerging issues within the food system from field-to-fork,” said Danielle Lee, UC Nutrition Policy Institute director of communications and research engagement.
“Over one-third of all available food in the U.S. is uneaten through food loss or waste – totaling up to over $160 billion – which has negative impacts on food security and the climate,” she said. “Households could save over $370 per person each year by reducing or preventing food waste. Additionally, when uneaten food ends up in the landfill, it generates greenhouse gases, and landfills are now the third largest producers of methane in the U.S.”
“California's adoption of SB 1383 aims to solve these problems,” Lee said. “You'll meet experts who are implementing consumer education and organic waste recycling programs aligned with SB 1383.”
The second 90-minute webinar, on Feb. 29, will focus on nutritious foods for residents of correctional facilities.
“We chose incarcerated people as our case study population for two reasons – the California Department of Corrections and Rehabilitation is the single largest public purchaser of food in the state and studies have shown that 63% of incarcerated individuals rarely or never have fresh vegetables and 55% rarely or never have fresh fruit.”
California has two policies that can support institutional procurement of fresh produce – AB 822 and AB 778.
“The Harvest of the Month program is an innovative solution to implementing these policies while supporting improved nutrition security for incarcerated individuals,” Lee said. “Prison gardening programs can not only provide therapeutic benefits to residents, but also reduce recidivism rates and serve as workforce development opportunities to better prepare residents for returning to their communities post-incarceration.”
Part 1 - Harvesting Solutions: A Trio of Perspectives on Addressing Food Waste from Field to Fork
Thursday, Feb 22, at 10-11:30 a.m. PT
To minimize food waste, three experts explore factors influencing food loss and waste, delve into innovative recycling techniques, and explore statewide initiatives targeting household food waste. Experts in postharvest handling, food waste recycling and community education will share research findings and strategies.

UC Master Food Preservers turn food scraps into gifts Dec. 1
Free online class offers recipes for using food scraps, answers questions about food preservation
“Putting food in our bellies instead of landfills is good for the planet,” said Sue Mosbacher, University of California Master Food Preserver Program coordinator. In landfills, decaying food releases methane, a greenhouse gas that contributes to climate change.
“We can reduce food waste and save money by creating new foods from food scraps,” Mosbacher said. “Instead of throwing away a lemon peel after squeezing out the juice, use the lemon zest to make lemon curd or citrus salt. They make wonderful homemade gifts for the holidays.”
UC Cooperative Extension Master Food Preservers, a program of UC Agriculture and Natural Resources, provides ideas for using leftovers and advice for safely preserving food.
On Dec. 1, 6:30 to 7:30 p.m., UCCE Master Food Preserver volunteers of Amador and Calaveras counties will host a free online class to show samples of apple honey, citrus salt, strawberry vinaigrette, sugared walnuts and lemon curd. Recipes will be emailed to participants.
“Many of these gifts are inexpensive to make because you're using food scraps – such as lemon rind or apple peel – and a few other ingredients. You can put the citrus salt in jars you've saved,” Mosbacher said. “It is easy to make and there's no special equipment needed.”
After the “show and tell” session, the UCCE Master Food Preserver volunteers will answer participants' questions about freezing, dehydrating and canning foods and food safety.
Because the class is online, anyone can participate, regardless of their location. Register for the one-hour Zoom workshop at https://mfp.ucanr.edu/Events/?calitem=516566.
The UCCE Master Food Preserver Program extends UC research-based information about home food safety and preservation to the public throughout the year. UCCE Master Food Preserver volunteers are located in 19 counties of California, most recently certifying volunteers in Modoc County, where they are offering pressure canner testing.
UCCE Master Food Preserver volunteers host monthly workshops on the first Wednesday of each month, with hosting duties rotating between Sacramento, El Dorado, Amador and Calaveras counties.
For 2022, the UCCE Master Food Preservers of Sacramento County are planning to offer the following workshops via Zoom:
- Jan. 19 – Citrus for Super Bowl
- Feb. 16 – Dehydration for Soups
- March 16 – Soups & Roots
- April 20 – “Night of Fermenting” Cheese/Yogurt/Sauerkraut
- May 18 – Jams & Jellies
- June 15 – “Ready for BBQ Season” Condiments & Beverages
- July 20 - Red, White & Blue
- Aug. 17 – “Tomato Mania” Salsas, Sauces & Peppers
- Sept. 21 – Sausages & Mustards
