Lee and Kim (2011) reported that the fixed carbon was 79.3% from Q. acutissima and 80.2% from Q. serrata. Shin and Kim (2013) found that the fixed carbon of charcoal from Q. phillyraeoides ranged from 86.31% to 85.97%.…”

A modified charcoal kiln was developed for both thermal therapy and charcoal production. The design of a modified kiln for thermal therapy focused on safety and cleanliness, plus the production of good quality charcoal. Two entrances in the kiln were designed for convenient charcoal production and thermal therapy. A barrier wall designed for noxious gases was installed between the adjoining charcoal kilns for safe thermal therapy. Additionally, a fine dust collector was installed to remove the fine dust generated during charcoal production. To verify the safety of the kiln, fine dust and harmful gases, such as carbon monoxide (CO), carbon dioxide (CO2), nitrogen dioxide (NO2), and radon (Rn), were measured after the charring process. The quality of the charcoal produced in the thermal therapy kiln was also examined. To evaluate charcoal quality, some physical properties and results from a proximate analysis were evaluated using Korean standards. The measurements of harmful substances and fine dust in the modified charcoal kiln met the criterion of the Ministry of Environment Clean Air Conservation Act in Korea. In addition, there were no noticeable differences in the monthly charcoal characteristics prepared from the thermal therapy kiln, and the charcoal characteristics also met the reference values of the Korea Forest Service.

“…When this process is performed at high temperature, it produces solid (charcoal), liquid (water and organics), gas (CO, CO 2 , CH 4 , H 2 ), carbonaceous aerosol pollutants (Organic Carbon or OC, Elemental Carbon or EC, etc. ) and particular matters (PM2.5 and PM10) and those compositions are strongly dependent on the nature of feedstock, the process conditions, kiln types, carbonization temperature and the adopted technologies (FAO, 1987;Madani et al, 1992;Jo et al 2005;Lee and Kim, 2010 a;Lee and Kim, 2011;de Carvalho et al, 2013;Chidumayo and Gumbo, 2013;Jeong et al, 2016;Magnone et al, 2016;Yang et al, 2017;Kang et al, 2018).…”

Herein, a case study discussing the effect of carbonaceous aerosol pollution, which is emitted during the charcoal kiln manufacturing processes or carbonization processes, on the atmospheric environment is presented . In South Korea, in situ analysis of different charcoal production plants specialized in the production of charcoal sauna indicate that the emitted organic carbon (OC) and elemental carbon (EC) aerosols are significantly influenced by the nature of the biomass and technological processes, i.e., treatment or emissions abatement systems for the exhaust effluent gases. In detail, total carbon (TC), which is calculated as the sum of OC and EC emission factors, varied widely from a charcoal production site to another ranging from 21.8 to 35.8 gTC/kg-oak, where the mean value for the considered production sites was approximately 28 gTC/kg-oak (N = 7 and sum = 196.4). Results indicate that the emission factors from a modern charcoal production process in South Korea are quantitatively lower in comparison with the traditional kiln. This study aims to propose advanced wood processes for the production of charcoal from the viewpoint of environmental protection policy and green engineering.

“…According to Lee and Kim (2011), higher specific surface area had higher moisture absorption capacity. In general, black (soft) charcoal which made at lower temperature (below 600℃) has 0.1-13.7 m 2 /g of specific surface area, and white (hard) charcoal which made at higher temperature (above 800℃) has 53.2-372.6 m 2 /g of specific surface area .…”

Increases of public attention on healthy environment lead to the regulation of indoor air quality such as Clean Healthy House Construction Standard. This standard covers emission of total volatile organic compounds (TVOCs) (e.g., formaldehyde, benzene, and toluene), ventilation, and use of environmentally-friendly products or functional products. Moisture absorption and desorption abilities are a recommended functionality for improving indoor air quality. In this study, moisture absorption and desorption capacities of carbonized board from wood-based panels and other materials were determined by using UNT-HEAT-01 according to ISO 24358:2008. Pine had higher moisture absorption and desorption capacities (49.0 g/m 2 and 35.3 g/m 2 , respectively) than hinoki cypress, cement board, gypsum board, oriented strand board, and medium density fiberboard (MDF). The moisture absorption and desorption capacities differed considerably according to the wood species. After carbonization process at 400℃, the absorption and desorption ability of MDF increased to 38% and 60%, respectively. However, moisture absorption and desorption capacities decreased with increasing carbonization temperature, but they were still higher than original MDF.) Therefore, it is suggested that carbonization below 600℃ can improve moisture absorption/desorption capacities.
