Large quantities of volatile organic compounds (VOCs) are released from heat-treated bamboo during the manufacturing process of recombinant bamboo, which affects the environment and human health. In this study, bamboo was treated at 150 °C, 180 °C, and 210 °C for 3 h, and VOCs were collected every hour using a Tenax tube. The VOCs were analyzed with gas chromatography-mass spectrometry (GC-MS) to explore the effect of temperature and time on weight loss ratio, main components, and their relative proportions. The results showed that temperature considerably influenced weight loss ratio, and weight loss ratio increased rapidly at high temperature. Massive quantities of VOC were emitted during the first hour of treatment, and emissions decreased as the time and temperature increased. Terpenes were the primary component of the VOC emissions. Temperature and time exhibited minimal effects on the type of primary components, and the relative proportion of some components exhibited negligible changes over a range of temperatures and times.

“…The source of monoterpenes is the considerable amount of natural resin found in the studied species, which are resiniferous. Softwood contains terpenes from mono to tetraterpenes-except sesquiterpenes, which are rare [18,32,54]. Terpenes are the source of primary emission, as those compounds are emitted directly from wood [55].…”

The qualitative and quantitative composition of volatile organic compounds (VOC) emitted from furnishings from solid wood and all kinds of wood derivative materials depends on many factors, of which the most important is the wood species. The intraspecies and interspecies differences in VOC emission result from the differences in the chemical composition and anatomical structure of heartwood and sapwood of different species. VOC composition analysis was performed separately for heartwood and sapwood of Scots pine (Pinus sylvestris L.), Norway spruce (Picea abies (L.) Karst.) and European larch (Larix decidua Mill.) trees. The studies were conducted in a glass climatic chamber of 0.025 m3, equipped with a system for the monitoring and control of climatic conditions. Samples of air for analyses were collected after 3, 7, 14 and 28 days of exposure. The results provided evidence for interspecies and intraspecies differences in the qualitative and quantitative compositions of VOC. The concentration of total VOC (TVOC) released from heartwood of Scots pine was higher than that released from sapwood. For European larch and Norway spruce, the opposite relations were observed. The VOC emission from Scots pine heartwood was about 17 times higher than the emission from European larch and Norway spruce heartwood. The differences in TVOC emitted from the sapwood of samples from different species were smaller. For each of the species, the highest percentage contribution to TVOC was made by terpenes. The second highest percentage contribution in TVOC was made by compounds containing a carbonyl group, mainly aldehydes, while aromatic compounds made the third highest contribution.

“…Granstrom reported that the emission of tepenes per unit mass of ovendry weight increased with increased drying temperature and decreased wood moisture content. She further reported that sawdust dried in steam dryers emitted 50-70% of the initial monoterpene content when dried to 6-12% moisture content Granstrom, 2009).…”

Experiments were carried out to test the capacity for a laboratory-scale biofilter operated at an elevated temperature level (∼50°C) to remove an air stream containing β-caryophyllene, a naturally occurring sesquiterpene of environmental concern emitted from wood-related industrial facilities. A water jacket was used to maintain high temperatures in a laboratory-scale biofilter. Inocula, pollutant loading and nutrient supply rate effects were evaluated over 84 days of biofilter operation. The start-up process took over two months when citrus peels were used as inocula while a relatively short start-up period was achieved after introducing forest compost products. While using a sparged-gas bioreactor to cultivate an enrichment culture for 97 days, removal efficiencies in excess of 80% were observed after 18 days. At empty bed contact times of 50 s and at a pollutant loading rate of 3.05 mg C/L/hr, removal efficiency levels reached 90% and the elimination capacity level reached 2.29 mg C/L/hr, corresponding to an elimination capacity of 2.60 mg β-caryophyllene/L/hr. Collectively, these results demonstrate that β-caryophyllene can be successfully removed from contaminated air using a biofilter operated at a high temperature (∼50°C), expanding the temperature range within which biofilters are known to biodegrade sesquiterpenes.
