This document prepared under contract from the California Integrated Waste Management Board reports the results of a study of ammonia and volatile organic compound emissions from greenwaste compost windrows that was conducted at Tierra Verde Industries in 2002. Researchers compared air emissions from a high-nitrogen windrow made up of grassy materials against a high-carbon windrow made up of primarily woody materials. Researchers also compared air emissions from windrows which were mechanically turned against windrows which were allowed to sit without mechanical aeration. Researchers also attempted to correlate readings from a hand-held gas analyzer with readings taken using a surface isolation flux chamber.
