Petroleum and other nonrenewable fossil fuels are commonly used for fuels, energy, plastics, industrial chemicals, pharmaceuticals, cosmetics and other materials we use daily. But many of these products can be made using plant compounds, oils and fiber. Dedicated feedstock crops are an important source of biomass and bioproducts. They can also be derived from food and agricultural wastes like corn stalks, wood chips, and nut and soybean hulls.

Recycling agricultural wastes into bioproducts reduces the need for incineration, landfills and other disposal methods that contribute to global warming and harm human health and the environment. Creating bioproducts from agricultural wastes also conserves land for food production and other needs and provides farmers additional revenue streams.
Biofuels and other bioproducts offer a way to improve energy security, fod security and national security while also cutting back on fossil fuel-related pollution and climate change. Biobased industries can also generate new jobs and economic activity nationwide.
The multistate structure provides numerous benefits.
Collaboration allows scientists with diverse expertise and skills to share knowledge and resources. Coordination reduces unnecessary duplication of efforts, and regular meetings help scientists stay on top of innovations and emerging issues. Connection and support also keep project members engaged, facilitating long-term research and development.
The Land-grant University System has unique assets that boost this project’s capacity for impact. Land-grant Universities have state-of-the-art labs; experimental fields in various environments; a widespread network of Extension educators and communicators to share findings, technology and practices; and strong relationships with government agencies, nonprofits, farm and commodity groups, and the rivate sector.
Through university teaching positions, project members are able to develop future scientists, engineers, farmers and bioindustry professionals.
Research Highlights
Researchers enhanced existing biomass feedstock, identified new biomass sources and developed new bioproducts. For example:
Low-value lactose from large dairy manufacturing sites can be used to affordably produce PHA (a biodegradable, biobased plastic with a wide range of applications including packaging films and containers) at commercial scales. California
Pigments extracted from corn can be used as natural food dye that is safer than the commonly used petroleum-based Red 40 dye. Illinois
Researchers extracted and patented antimicrobial compounds from lignin bio-oil. Kentucky
Experiments could result in biobased nanocellulose that can be used to heal wounds. Virginia
Forest residues could be used to create aerogel biosorbents that remove toxic heavy metals from water bodies. Wisconsin
Genetically modifed camelina uses nitrogen more efficiently and is more suitable for biofuel production. Montana
Switchgrass and miscanthus can produce high biomass yields on low quality soils. New York
Industrial hemp can be used in numerous bioproducts and has the potential to be a major commodity crop in the southern U.S. Kentucky
Duckweed is economically viable for New Jersey farmers. New Jersey
Researchers developed technically feasible, cost-effective, sustainable technologies for converting biomass into useful materials and identified reliable, economical systems for producing, storing and transporting biomass. Specifically, researchers:
Patented a way to create syngas from municipal solid wastes and switchgrass produces more gallons per year than traditional technologies and would result in an estimated $33 million increase in a biorefinery’s annual net revenue. Oklahoma
Developed no-till production systems for sugar beets (commonly used for ethanol) that improve soil health and save farmers aout $110 per acre in fuel, machinery and labor costs. Montana
Identified a new co-fermentation strategy that drastically improves ethanol yield from cellobionate and glycerol. California
Developed a microwave-assisted process that improves the yield and quality of bio-oil and syngas made from biomass and plastic wastes. Minnesota
Identified gentler pretreatments that cost-effectively convert biomass into biofuels with fewer environmental impacts. Illinois
Developed a biomass pretreatment that reduces water, energy and chemical consumption. Kansas
Pioneered new pretreatment and manufacturing technologies to process biomass into jet fuel, bioplastics and carbon fiber. Washington
Designed a new horizontal reactor that minimizes the energy needed to mix biomass with the enzymes used to break it down for ethanol production. Oregon
Found a way to produce graphene from agricultural and biochar wastes that can be used to manufacture biobased capacitors, semiconductors, ink for 3D printers and ore. Texas
Designed a mobile biorefinery system to convert waste flare-off gas from coal power plants into liquid biofuel. Mississippi
Optimized processes and technologies for producing biosurfactants, which can be used as cleaning products, preservatives and more. Iowa
Developed novel methods to rapidly separate lignin from lignocellulosic biomass for production of aromatic chemicals. Louisiana
Developed techniques to modify lignin so it can replace petroleum in phenols and acrylates, which are used in antiseptics, resins and more. Tennessee
Identified a process for using plant oil extraction byproducts to create affordable, durable, biodegradable fast-food packaging. Kansas
Developed an algal-bacterial process to treat poultry processing wastewater so it is safe to use in hydroponic irrigation. Alabama
Discovered a process that efficiently isolates cellulose nanocrystal and nanofiber from sawdust, prairie cordgrass and corn stover so it can be used in biopolymers and “smart” fertilizr. South Dakota
Developed new bioprocesses for producing high value bioproducts from lipid feedstocks, organic wastes and microalgae. Hawaii
Outlined parameters for successful systems in which brine shrimp convert algae into higher value biomass for bioenergy production. Missouri
Pioneered research on the way brown rot fungi breaks down cellulose, which has been advanced and patented by other researchers at national institutes and labs. Massachusetts
Showed that biochar — the carbon and ash byproduct of heating biomass in the absence of oxygen — can be applied to land to improve soil health and sequester carbon in soil instead of releasing it as a greenhouse gas. Michigan
Showed ethanol biorefineries how to improve long-term profitability by creating allulose (which is used as a low-calorie sweetener) in addition to ethanol during fermentation. Illinois
Calculated that biogas made from anaerobic digestion of animal manure can be competitive with natural gas prices. Iowa
Demonstrated th potential for carbon-negative bioprocessing. North Carolina
Models, pilot tests, technical reviews, and other efforts are facilitating the adoption of biobased systems. For example:
Calculated the life cycle sustainability and costs of new biobased products and processes, which helps policymakers, farmers and processing companies make decisions. Michigan, Ohio
Helped establish startup companies to commercialize technologies that use agricultural and forestry wastes for bioproducts. South Dakota
Developed commercial-scale systems to help with adoption of gasification technology. Texas
Designed and modeled an algal pond system and a freshwater shellfish pond system that can sustainably produce biomass and biofuels while also capturing carbon; worked with Clemson University facility services to adopt the systems and reduce the campus carbon footprint. South Carolina
