Al. Spongberg et al., LABORATORY-SCALE IN-VESSEL COMPOSTER DESIGNED FOR VOLATILE EMISSIONS ANALYSIS, Journal of environmental quality, 25(2), 1996, pp. 371-373
Airtight laboratory scale in-vessel composters equipped to capture gas
eous emissions were constructed from modified portable cement mixers.
Any compounds that are volatilized during composting can be collected
from the exiting air stream and quantified using gas chromatography. M
easurements of the amount of each compound vaporized and its residual
concentration can be used to determine air quality impacts and degrada
tion rates.
