Coffee Husk Waste for Fermentation Production of Mosquitocidal Bacteria

Journal of Economic Entomology, 2011
Coffee husk waste (CHW) discarded as bio-organic waste, from coffee industries, is rich in carbohydrates. The current study emphasizes the management of solid waste from agro-industrial residues for the production of biopesticides (Bacillus sphaericus, and B. thuringiensis subsp. israelensis), to control disease transmitting mosquito vectors.

Chemical Nature of Spent Coffee Grounds and Husks

Australian Journal of Chemistry, 2020
Waste coffee husks and spent coffee grounds (SCGs) are produced in large qualities worldwide. Characterisation of these waste streams from Australian commercial outlets in terms of lipid, caffeine, and polyphenol content was undertaken giving values up to 10 % lipids and 23 mg g−1 phenols from SCGs, consistent with reports from other parts of the world.

Development of fiber-reinforced polypropylene with NaOH pretreated rice and coffee husks as fillers: Mechanical and thermal properties

Journal of Thermoplastic Composite Materials, 2020
Incorporation of agricultural wastes as fillers in fiber-reinforced plastics is gaining momentum in plastics engineering research. In this study, fiber-reinforced polypropylene (PP) with rice and coffee husks as filler material were developed. The effect

Coffee Husk Briquettes: A New Renewable Energy Source

Energy Sources, 2003
In the rural region of Segundo Frente, in Cuba, due to the present rate of deforestation, the local authorities have carried out severe restrictions over the fuelwood collection, and it is necessary to introduce other sources of cheap and available fuels.

Coffee Husks Characterization for the Fast Pyrolysis Process

Materials Science Forum, 2017
The lignocellulosic biomass is a renewable alternative for fossil fuels. The extensive cultivation of coffee grounds in Brazil generates a large amount of residues, as coffee husks. The work aimed at performing the coffee husks characterization, investigating the viability for fast pyrolysis application.

Study on the biogas potential of anaerobic digestion of coffee husks wastes in Ethiopia

Waste Management Research, 2020
The poorly controlled discharge of coffee husks in Ethiopia causes severe environmental pollution and is a waste of resources. The volatile solid and carbon content in coffee husks waste indicates that it is rich in organic matter and has huge potential ...

Biochars obtained from arabica coffee husks by a pyrolysis process: characterization and application in Fe(ii) removal in aqueous systems

, 2020
In this work biochars were synthesized from arabica coffee husks and were used for Fe(II) adsorption by a pyrolysis process at 350 and 600 °C. The in natura material before and after pyrolysis exhibited an amorphous structure, showing C, H, and N levels,

Gibberellic Acid Production by Solid-State Fermentation in Coffee Husk

Applied Biochemistry and Biotechnology, 2002
Five strains of Gibberella fujikuroi and one of Fusarium moniliforme were screened for the production of gibberellic acid (GA3) in coffee husk, and based on the results, one strain, G. fujikuroi LPB-06, was selected. The comparative production of GA3 by solid-state fermentation and submerged fermentation indicated better productivity with the former ...

Adsorption of Ni(II) on spent coffee and coffee husk based activated carbon

Journal of Environmental Chemical Engineering, 2018
Abstract Adsorption of Ni(II) on low cost activated carbon (AC) from spent coffee (SAC) and coffee husk (HAC) has been studied. Porous textures of adsorbents were characterized by N2 and CO2 sorption measurements. Batch adsorption experiments were performed as a function of adsorbent dose, Ni(II)-concentration and pH.

Detection of adulterations in processed coffee with cereals and coffee husks using capillary zone electrophoresis

Journal of Separation Science, 2009
AbstractThe proposed method for the identification of adulteration was based on the controlled acid hydrolysis of xylan and starch present in some vegetable adulterants, followed by the analysis of the resulting xylose and glucose, which are the monosaccharides that compose, respectively, the two polysaccharides.
