“…Commercially coffee husks has been used as a fermented tea such as coffee cherry tea, cascara, sultana, qishrorbun, whereas coarse powdered coffee husks are used as food supplements in granolas, smoothies and juices. Although the reported applications of coffee husks includes, as an additive in animal feed, production of bulky chemical compounds, fermentation for production of numerous products [16], as an absorbents [17], as a fertilizers [18] and as a raw material for fuel production [19]. However, keeping in consideration the sizeable amounts generated and only a small portion of this solid residue is being used for practical applications, there is still need to find other alternative uses for this frequently produced solid residue.…”

The aim of present research work was to explore the constituents of the coffee husks oil obtained from Coffee arabica. L (Rubiaceae). Hydrodistillation extraction has been applied to extraction of volatile oil from coffee husks of C. arabica and the chemical constituents of the oil has been investigated by using by Gas Chromatography (GC), Gas Chromatography/Mass Spectrometry (GC/MS) and carban-13 Nuclear Magnetic Resonance ( 13 C NMR). GC and GC-MS analysis reveals the presence of fifty five components in a significant amount in the coffee husk volatile oil. The most abundant components present in oil were butylatedhydroxy (65.83%), 1, 2-benzenedicarboxilic acid (7.28%), phenylethyl alcohol (1.69%) and 2, 3-isopropylidene-6-decoxyhexo (1.63%). Essential oil as well as ethanol extract were screened for antimicrobial and antioxidant activities and were found active against both the assays.

“…HTAG was reported as a good way of utilizing plastic containing fuel [9]. This technology was also used in experimental studies that were conducted using tropical coffee husks under high temperature conditions [10]. It was found the positive influence of high temperature on increasing the gasification process.…”

Abstract. Combustion and gasification technology utilizing high-cycle regenerative air/steam preheater has drawn increased attention in many application areas. The process is to be realized at temperature level above ash melting point using highly preheated agent. The use of highly preheated media above 900 o C provides additional energy to conversion processes and results in considerable changes to the design of combustion and gasification equipment and its performance. This paper presents an advanced gasification system that utilizes high-temperature air and steam to convert biomass and municipal wastes into syngas production as well as selected results from experimental studies of high temperature air/steam gasification.

Thermal characterization of coffee husk (Coffea arabica) from Colombian coffee has been studied. Different products, mostly volatile and semi-volatile compounds, were analyzed paying special attention to 16 polycyclic aromatic hydrocarbon classified by Environmental Protection Agency (EPA) as priority pollutants, frequently used for checking toxicity in environmental samples. Fixed amount of raw material was
