Turning agricultural waste to treasure

New funding will help Berkeley Lab and partners improve how the diverse agricultural waste in California’s Northern San Joaquin Valley can be used to make sustainable bioproducts and biofuels.

• Agricultural residues and wastes from growing and processing crops can provide the raw materials needed to make bio-based products, materials, and fuels.
• A new award will help researchers build a publicly accessible database to guide farmers, biomanufacturers, and community leaders in the Northern San Joaquin Valley in building up a bioeconomy.
• The project will also investigate flexible conversion methods that can process mixtures of agricultural waste into the building blocks for bioproducts, biofuels, and biochemicals, making it easier for companies to use different kinds of plant matter.

In California’s Northern San Joaquin Valley, agricultural leftovers such as almond shells, fruit peels, and orchard trimmings can potentially be converted into sustainable bioproducts and biofuels – with the right technology. Today, Schmidt Sciences’ Virtual Institute on Feedstocks of the Future awarded new funding to a group investigating how to make better use of the diverse agricultural waste in the region.

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 Albany Agricultural Research Station.

“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.

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 […]
