What is it about?
This study examines the volatile organic compounds (VOCs) produced during hot-pressing and subsequently with time (as in use) of plywood bonded with renewable components. A range of VOCs are produced when wood furnish (veneer) is hot-pressed with some of these VOCs also prominent in panel emissions obtained from chamber testing. Use of each renewable can contribute additional VOCs and/or reduce VOCs evolved during panel manufacture. Soy flour and gluten meal contributed additional VOCs whereas as lignin and particularly tannin act to reduce key VOCs such as formaldehyde.

Why is it important?
These results have implications as to how VOCs generated in panel manufacture can be managed or reduced during panel production (worker health/exposure) as well as longer term, in use (indoor air quality)
