“…Previous studies on crude bamboo PL have focused on phenolic compounds. Most phenolic compounds present an aromatic ring and a short carbon chain, including guaiacol, vanillin, and apocin, among others, whose antimicrobial activities and employment by food companies are widely known [14,[22][23][24][25][26]. Table 1 highlights the phenolic compounds whose qualitative identification by MS are comparable to those ones described by other authors.…”

Considering that the pyroligneous liquor obtained from pyrolysis of various types of biomass has antiviral activity, the main objective of the present study was to evaluate the antimicrobial action of the methanolic fraction extracted from bamboo (Dendrocalamus asper) pyroligneous liquor in relation to Escherichia coli and Staphylococcus aureus bacteria. The pyroligneous liquor was recovered by laboratorial bamboo pyrolysis at 350 °C and then fractioned by liquid-liquid separation with methanol and hexane. After solvent evaporation, we collected the methanolic extract, which was later diluted in methanol and used in the diffusion disc assay of E. coli and S. aureus at concentrations of 0.125, 0.500, 0.750 and 1.000 mg. Through GC/MS analysis, it was possible to qualitatively identify 92 chemical compounds in the methanolic fraction. Treatment with the methanolic fraction inhibited cellular growth and caused a variety of morphological variations in size as well as deformities in the bacterial cell walls, establishing an antimicrobial activity profile. This finding supports the National Policy for Incentives for Sustainable Management and Cultivation of Bamboo (PNMCB) and has benefits to the society and environment as a whole, as it demonstrates the possibility of adding value to a byproduct of pyrolysis.

“…Among their chemical properties, the phenols present a great versatility of use as starting material and as intermediates in the production of molecules of greater complexity, as well as in the production of phenolic resins (MIGLIORINI et al, 2013). However, in the concentration ranges detected and considering it to be an aqueous matrix, some studies have proposed its application as a fungicide (SUMANATRAKUL et al, 2015). Guaiacol (methoxyphenol) causes darkening in the sample when exposed to air and light and can be used as an indicator for enzymes, expectorant, antiseptic and anesthetic.…”

The peach stone is considered an agroindustrial residue originating from the industrial process of peach in halves in syrup. It does not have an adequate destination, its final disposal is incorrect and may cause contamination in the environmental compartments. In this way, the burning of this raw material as biomass enables its reuse, besides adding value to the residue. Among the processes used for the application of this residue is the carbonization process, which allows to obtain co-products with higher added value, such as pyroligneous liquid, which represents a fraction of organic compounds condensed from the smoke emitted during carbonization. The quality of the liquid depends on the process conditions and the biomass used. Therefore, the objective of this study was to characterize the sample of pyrolignous liquid obtained from the carbonization of the peach stone, on an industrial scale, qualitative and semi quantitative. Preliminary characterization (pH, conductivity, color, density and contents of tar, organic matter and acidity) and a chemical characterization by gas chromatography coupled to mass spectrometry (GC-MS) were performed. The liquid presented satisfactory results for the physico-chemical evaluations. Regarding the qualitative determination, it was possible to identify 49 compounds. Highlighting the phenols, with 44.90% of the number of compounds, mainly methoxyphenols. These are compounds with significant added value and industrial importance, indicating their use as raw material in the production of polymer resins, among other purposes.

“…Liquid smoke has well-known uses as antimicrobial. There was presented the use of liquid smoke as coagulating and antifungal agents for latex [27]. Therefore liquid smoke has the potential for use as a natural antimicrobial in industrial applications where the smoke flavour is desired.…”

This study aim is to explain the contribution of tobacco waste in the agricultural sector. Tobacco waste here limited to tobacco stems only. Tobacco stems are processed into bio briquettes, pellets, and liquid smoke. Biobriquettes and bio pellets can substitute the use of coal as fuel while liquid smoke can replace the use of chemical insecticides. The three products are eco-friendly and safe for the consumers. The production of these three products is a contribution manifestation of tobacco waste utilization to increase agriculture productivity, reducing fossil energy use, and minimizing tobacco stakeholders from chemical contamination both on tobacco plantation area and tobacco barns.
