Question

Hello,
This platform of research is very engaging and the project video was informative and flowed fluently!
Just a couple questions because I am curious.
How did the team decide on cutting the straw 2-3 cm? Is this for a certain structural design or does the straw adhere to each other better at this length?
Also, does the team see any issues with how the wheat straw panels are biodegradable? For example, the panels may degrade and collapse at a higher rate than conventional drywall, creating an issue with the lifespan of buildings, homes, etc.
Thanks so much!

Hello! Thank you for your comment, as far as the choice for straw size we believe that this length is the most suitable in terms of a starting material that can then be converted into pulp through the Kraft process. Smaller straw lengths are the result of our primary steps to blend down the raw materials into uniform lengths, and any smaller than the sizes chosen would be more difficult to control in terms of uniformity. As for your second question, we have created a suite of tests to determine if the panel boards that we created will be able to handle the application that they are intended for. In this regard, we look to test the panel boards using the suite of tests above. We have included several tests to evaluate certain parameters, like creep resistance, to see how time will play a factor in the performance of our panel boards with a load application, as well as the degradation of the performance of the boards over time.
