Natural Additive for Reducing Formaldehyde Emissions in Urea-Formaldehyde Resins

open access: yesJournal of Renewable Materials, 2016
This work studies the use of soy protein as a natural formaldehyde scavenger in wood particleboard production. The protein is incorporated in two forms: a) as a powder, during the blending process of wood particles with urea-formaldehyde binder resin, and b) as an aqueous solution, added at different times during resin synthesis.

Seasonal and interannual variability of North American isoprene emissions as determined by formaldehyde column measurements from space [PDF]

open access: yes, 2003
Formaldehyde (HCHO) columns measured from space by solar UV backscatter allow mapping of reactive hydrocarbon emissions. The principal contributor to these emissions during the growing season is the biogenic hydrocarbon isoprene, which is of great ...
