“…Windrow composting is the most common form of composting, and at all scales it has been extensively developed and evaluated, with numerous reports in the literature (Campos et al, 2014). Recent research has demonstrated success in the cigarette tobacco composting process in a reactor, which is an efficient technology to reduce tobacco toxicity and produce matured compost (Kopcic et al, 2014;Zittel et al, 2018).…”

“…Different models of reactors were developed and adapted for the treatment of different organic residues as vertical and horizontal, aerobic, anaerobic and facultative (Karnchanawong;Suriyanon, 2011;Kopcic et al, 2014;Jeonga et al, 2017;Zittel et al, 2018). Reactors are systems that usually protect the composting process from environmental factors such as humidity and temperature.…”

“…Reactors are systems that usually protect the composting process from environmental factors such as humidity and temperature. Research has evidenced that these biodegradation pro-cesses are efficient, using reactors systems in pilot and domestic scales, with forced and natural aeration system (Karnchanawong;Suriyanon, 2011;Jeonga et al, 2017;Zittel et al, 2018).…”

“…The treatment does not require the composting compound to be stirred and provides sufficient ventilation for the process, it does not produce unpleasant odors, leaching or even the formation of pollutants. In addition, it provides physical-chemical parameter control and can be used in different weather conditions (Campos et al, 2017;Zittel et al, 2018). Studies about stability and maturity of composts produced by physicochemical analyzes (temperature, humidity, pH, C/N ratio) associated with spectroscopic techniques (FTIR and UV-Vis) have been demonstrated that this process is efficient.…”

“…Researchers have shown that DOW and SCT composting in 200 L volume facultative reactors from different initial C/N ratios yielded matured, stabilized and non-toxic composts (Zittel et al, 2018). The initial C/N ratio is an important point for the composting process, since these elements are sources of nutrients for decomposing microorganisms, which throughout the composting process tend to reduce.…”

Organic waste is among the solid waste produced worldwide. When such residue is improperly accumulated and disposed of, it generates environmental impacts, polluting soils, rivers and the air. The objective of the present study was to investigate the use of a 2000 liter capacity reactor for composting domestic organic waste, wood chips and smuggled cigarette tobacco. Physicochemical analyzes (pH, temperature, humidity and C/N ratio), biological (germination test and pathogens) and spectroscopic (UV-Vis and FTIR) analyzes were performed to monitor the process. In addition, the influence of two different C/N ratios was investigated. C/N ratio analyses and phytotoxicity tests showed that the compound reached maturity over a period of 120 days. Spectroscopic analyzes of UV-Vis and FTIR showed efficiency, indicating the degradation of compounds of simpler structure and the formation of humified compounds. The microbiological and heavy metal analyses of the final compounds revealed that the results are in accordance with the legislation. The different C/N ratios showed very close results, not affecting the composting process. Thus, the proposed treatment of domestic organic waste and smuggled cigarette tobacco in facultative reactors of 2000 liters was seen to be efficient and produced mature compound in the different C/N ratios studied.
