“…The Greek peaty lignite of the Megalopolis Basin, formed during the Quaternary period and comprising significant quantities of humic substances and inorganic content [ 7 , 8 ], may be an effective raw material for obtaining both humic substances and fly ash. During the last fifty years, Megalopolis lignite has been almost solely utilized for power generation producing solid wastes such as fly ash, bottom ash, boiler slag, and flue gas desulphurization materials, which have been commonly treated as wastes.…”

Fly ash superficially modified with humic substances from the Megalopolis lignitic power plant was prepared and evaluated for agricultural uses. UV-vis spectrophotometry and IR spectroscopy revealed that fly ash shows high sorption efficiency towards humic substances. Adsorption proceeds stepwise via strong Coulombic and hydrophophic forces of attraction between guest and host materials. Langmuir, Freundlich, BET, Harkins-Jura, and Dubinin-Radushkevich isotherm models were employed to evaluate the ongoing adsorption and shed light to the physicochemical properties of the sorbent-adsorbate system. Humic substances desorption and microbial cultivation experiments were also carried out to examine the regeneration of the humates under washing and explore the possibility of this material acclimatizing in real soil conditions, both useful for biofunctional agricultural applications.

“…En complemento a las fuentes tradicionales para la elaboración de enmiendas orgánicas, los carbones de bajo rango o carbones pobres, en algunos países ha sido considerado como una materia prima más homogénea y de oferta relativamente constante (Giannouli et al, 2009;Cubillos et al, 2017;Valero et al, 2018). Desde mediados del siglo XX es común la obtención de SH a partir de leonarditas, carbones pardos, lignitos e incluso carbones bituminosos, de tal suerte que en la actualidad los CBR se han considerado como fuente apropiada para la obtención de enmiendas orgánicas ricas en SH (Chassapis y Roulia, 2008). Se ha concluido que la posibilidad de usar materiales carbonosos como materia prima para el desarrollo de enmiendas y fertilizantes orgánicos para el sector agrícola, depende de las características particulares del material que se pretenda utilizar, puesto que existe una variación significativa entre carbones procedentes de diferentes yacimientos (Taylor y Francis, 2004).…”

ResumenEl objetivo de este trabajo fue identificar alternativas biotecnológicas para transformar el carbón en compuestos más simples en estado líquido. Se realizó una revisión bibliográfica actualizada relacionada con el uso de la materia orgánica humificada. El análisis documental mostró que la materia orgánica humificada en el suelo mejora las características físicas y químicas del mismo, estimula las poblaciones microbianas y promueve el crecimiento y desarrollo de las plantas. Los carbones de bajo rango se han considerado una buena fuente de sustancias húmicas. La extracción de estas sustancias se puede realizar mediante métodos químicos o a través de la solubilización de carbones de bajo rango utilizando microorganismos. Sin embargo, no ha sido posible el desarrollo de una tecnología eficiente y de bajo costo. En el suelo podría tener lugar un control natural de la transformación del carbón por microorganismos, similar a lo que ocurre con la descomposición de la AbstractThe aim of this work was to identify biotechnological alternatives for transforming the coal into simpler compounds in liquid state. An updated bibliographic review related to the use of humified organic matter was done. The documentary analysis showed that humified organic matter in the soil improves its physical and chemical properties, stimulates microbial populations and promotes plant growth and development. Lowevolved coals or low rank coals have been considered a good source of humic substances. Extraction of these substances can be performed by chemical methods or through solubilization of low rank coals using microorganisms. However, the development of an efficient and low-cost technology has not been possible. A natural control of coal transformation may take place in the soil in the same way as the decomposition of lignin.
