What opportunities for training and professional development has the project provided?Two postdocs were trained by the company PerkinElmer to use chemometrics software to analyze data and perform multivariate modeling for packaging applications. How have the results been disseminated to communities of interest?We demonstrated results at a Forest Products Society Conference and webinar event. We reached an audience of more than 100 people from at least 10 manufacturers in the target market group.We also published these manuscripts in peer-reviewed journals. What do you plan to do during the next reporting period to accomplish the goals?We plan to continue to apply for funding to a) addition ofsoy flour to wood composite adhesives and b)develop sensors to detect formaldehyde in food-based packaging.
Impacts
What was accomplished under these goals?
Obj. 1. Identify potential packaging markets for wood composite materials. Determine the specifications and needs important for that market. During this project period, we met with 2 wood composite manufacturers and 2adhesive suppliers to discuss market needs.Because of nondisclosure agreements, we cannot provide their names. We continued to reach out to other wood composite manufacturers. We also determined the needs and specifications for each company and then tried to provide or collect data to see if we could meet their needs. Each company has a different target market and often has different preferences beyond the minimum engineering standards/codes. Obj. 4 Develop patents for new technology and/or leverage findings for external funding A second patent was awarded on January 26,2021, utilizing soy for wood composites and a patent numberwas given by the U.S. Patent and Trademark OfficePatent No.: US 10,899,039 B2. The present invention provides adequate bonding at reduced costs due to lower soy flour prices than petroleum-based adhesives. Methods were provided to formulate binders for wood composites comprising neat soy flour mixed with petroleum-based adhesives. These soy formulations were prepared by mixing with the adhesive and then sequentially adding to the composite. We were also able to leverage external funding to assist with the soy adhesive component of htis project. The following sources of external funding were secured during 2021: 2021 Soy Flour Based Resins For Hot And Cold-Pressed Wood Products Via United Soybean Board 1 year $146,000 2021 Use of Soy Flour in Engineered Wood Products in Alabama Via State Alabama Farmers Federation Soybean Producers 1 year $13,900

What was accomplished under these goals?
Obj. 1. Identify potential packaging markets for wood composite materials. Determine the specifications and needs important for that market. During this project period, we met with wood composite manufacturers from 3 different companies. Because of non-disclosure agreements, we cannot provide their names. We continued to reach out to wood composite manufacturers.We also determined the needs and specifications for each company. Each company has a different target market and often has different preferences beyond the minimum engineering standards/codes. Obj. 2+3.Develop wood composites for keypackaging markets that is light weight, cost effective, and environmentally friendly while usingvalue added nano-cellulose for high value packaging This study explored the possibility of making a lighter and cheaper oriented strand board (OSB) through the addition of lignin-retained cellulose nanofibers (LCNF). The main novelty of this study was that we created a standardized "cost ratio" table, which allows for a company to take their confidential adhesive and LCNF costs and easily determine if there is a projected increase or decrease in panel material costs (%) for lighter weight panels.A factorial design was deployed to understand the effect of resin amount, density, and nanocellulose amount would have on strength, moisture resistance, and internal bond. Based on the outputs of a multiple linear regression model, alightweight wood composite was developed that was equivalent in cost per pound and strength and required less petroleum-based adhesive.Our models revealed that a maximum density reduction of 0.05 g/cm3 might be possible if the cost of LCNF (solid basis) is equivalent to pMDI (1:1 ratio); conversely, it was determined that LCNF was not cost effective if it was 7 times more expensive than pMDI (7:1 ratio). Obj. 4Develop patents for new technology and/or leverage findings for external fundingA new products patent applicationwas submitted utilizing soy for wood composites and notice of allowance was given by the U.S. Patent and Trademark Office. The final patent will be issued during the next reporting period. In the notice of allowance, the claims were allowed that defined the scope ofthe protection for the invention.The allowed claims are directed to methods of preparing pressed wood composites where the synthetic resin comprises MDI. Independent claims 22 and 33 further require that the binder have a viscosity of less than about 1000 cp while independent claim 29 does not require a particular viscosity it does require the steps be performed sequentially. Additionally, independent claim 33 includes spraying as the application step.

Impacts
What was accomplished under these goals?
1. Pallets that use wood composite packaging were identified. We found companies want lower density wood composites for pallet decking if it performs equally and at a lower or equivalent cost. 2. The composite material that we have developed so far was indeed lighter weight. 3. Nanocellulose was applied to make a lighter weight composite. 4. An invention disclosure will be submitted during the next period that examines the process to making lighter weight panels that use lignincontaining nanocellulose.

Progress 10/01/17 to 09/30/18
Outputs
Target Audience:Oriented strand board (OSB) and adhesive suppliers to the packaging industry. Packaging applications such as crates and pallets could benefit from lower adhesive costs from bio-oil or value added nanocellulose. Industry also could use lower formaldehyde adhesives for applications where packaging might be confined to tight spaces. Changes/Problems:There has not been any changes to the project. There were two challenging problems that were encountered that we will work on in 2019. First, we were able to successfully make bio-oil out of lignin to manufacture OSB and use less petroleum based adhesive. However, the lignin is hard to break down resulting in low bio-oil yields. Second, for application of nanocellulose into OSB, we are having trouble applying the nanocellulose without adding too much water to the system. This is a common problem within the literature and we are working toward solving this issue in 2019. What opportunities for training and professional development has the project provided?Two post docs went to a weeklong free industry training session about the fundamentals of packaging at Printpack's Packaging Institute. This training helps for them to both apply to this research project as well as to train graduate and undergradute students in the lab and classroom. How have the results been disseminated to communities of interest?
Nothing Reported
What do you plan to do during the next reporting period to accomplish the goals?Application to grants and continued data collection in the lab to support the objectives and goals above.
Impacts
What was accomplished under these goals?
Industrial partners have been identified for support in using nanocellulose in oriented strand board (OSB) that could be used for packaging applications to crates and pallets. A graduate student successfully removed extractves to not only lower the weight but improve the interaction between flake and adhesive during bonding. Additionally, ways to disperse nanocellulose into OSB was achieved. This was a difficult task because the addition of nanocellulose increases the viscosity (thickens the solution) which makes it hard to apply. The impact of this project was such that we were able to gain interest from an oriented strand board and nanocellulose manufacturer. This collaboration with industry is important because they can provide the constraints necessary for a product to commercialize. Industry can also identify problems that prevent commercialization so that we can work to solve these problems in our laboratory.
