Hi Chris,
I am particularly keen on agricultural waste / by-product materials, in large part because the negative impacts of forestry can be avoided. Compressed straw board looks like a great option that doesn’t use adhesives, and presumably the process to bind lignin can be applied to other feedstock. Are you aware of any structural sections made this way, e.g., purlins?
In terms of the sequestered carbon I’m keen to look into this - in my opinion there needs to be a time value of keeping carbon out of the atmosphere, but what this inflation rate should be is a curly question!
Regards,
Will
