Brief Project Summary:
This project will continue the development of soy-based bailing twine to expand the use of soy material from soy meal to soy hulls. Because soy hulls are cheaper, stronger, and easier to grind into finer particles than soymeal, it is thought that PLA/soyhull twine will be cheaper and stronger than its PLA/soymeal counterpart. In this project, researchers will test this hypothesis and demonstrate the advantages and disadvantages of the two types of soy-based twine. Optimum processing conditions and formulation will be determined through this process. Actual use of the twine on bailers and the potential fabrication of a soy-based bailing net will also be considered.

Project Summary

This project is intended to continue the development of soy-based bailing twine to expand the used
soy material from soymeal to soyhull. Currently, we are developing twine based on PLA and
soymeal. Because soyhull is cheaper, harder/stronger, and easier to grind (into finer particles) than
soymeal, we hypothesize that PLA/soyhull twine will be cheaper and stronger than its
PLA/soymeal counterpart. We plan to test this hypothesis in this new project and demonstrate the
advantages and disadvantages of the two types of soy-based twine. We will use the same
processing and formulation methodology in the current project to develop the new PLA/soyhull
twine. Properties of the twine samples obtained under different conditions/formulations will be
tested and the results will be used as feedback to tailor the conditions. Optimum processing
conditions and formulation will be determined through this meticulous iteration process. The best
soy material (soymeal or soyhull) and the most suitable processing conditions for soy-based twine
production will become clear after completing this project. The actual use of the produced twine
on bailers and the potential fabrication of a soy-based bailing net will also be considered in this
project.

Project Objectives

Develop the formulation and processing conditions of PLA/soyhull twine and compare its
properties with those of PLA/soymeal twine to identify the most suitable soy material and
conditions for twine production.

Project Deliverables

• Optimal formulation and processing conditions for PLA/soyhull twine production
• Properties of the produced twine including mechanical characteristics and digestibility
• Clear understanding of the most suitable soy material and processing conditions for making
soy-based twine.
• Initial consideration on actual twine use and bailing net development

Final Project Results

Benefit To Soybean Farmers

• New industrial uses for soymeal and soyhull
• Increased soybean value and additional income source for soybean farmers

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
