“…Pyrolysis is one of the thermochemical conversion methods of biomass carried out in the complete or near complete absence of an oxidizing agent (air or oxygen) typically at 500-700 °C to provide complex fractions of gases, condensable liquids (tars), and char (solid residue) (Alén 2011b). It has been established that during pyrolysis, each constituent shows a unique thermochemical behavior (Alén et al 1996(Alén et al , 2002; Anca-Couce 2016; Bai and Kim 2016;Kan et al 2016;Kawamoto 2017;Lappi 2012;Lédé 2012;Patwardhan 2010;Piskorz et al 1986;de Wild 2015;Yang et al 2007;Zhou et al 2017). In previous experiments, for developing novel biorefinery concepts, the fast pyrolysis of hotwater-extracted and pulped hardwood sawdust was studied (Ghalibaf et al 2017).…”

The thermochemical behavior of Norway spruce (Picea abies) sawdust as such and after various chemical treatments (hot-water extraction, delignification, and hotwater extraction followed by delignification) was investigated by analytical pyrolysis-gas chromatography-mass spectrometry. In each case, the yields of major GC-amenable condensable products were semi-quantitatively measured, and the individual compounds were classified into several compound groups. The formation of these groups from feedstock samples with varying mass portions of their structural constituents (carbohydrates and lignin) was determined at 500 °C and 700 °C with a residence time of 5 s and 20 s. The formation of pyrolysis products was shown to be characteristically dependent on feedstock composition as well as on pyrolysis conditions. This kind of approach was of practical importance with respect to efforts not only to develop rapid characterization tools for lignocellulosics, but also to uncover new biorefinery possibilities to produce bio-oils, for example, enriched either with aliphatic or aromatic constituents.

“…Pyrolysis is a well-known method for converting woody biomass into charcoal. At the beginning of the twentieth century, this process was utilized for the commercial production of a wide range of fuels, solvents, chemicals, and other products from biomass feedstock (DE WILD, 2015). Recently, due to the global problems associated with the intense use of fossil fuels and waste generation, the interest in pyrolysis-based biorefineries (in modern varieties) is renewed (PRINS; PTASINSKI;JANSSEN, 2006).…”

“…The bio-oil is feedstock for a subsequent biorefinery approach that aims to further process the bio-oil into a spectrum of value-added products. Nonetheless, the interest in slow pyrolysis technology (both carbonization and torrefaction) is growing rapidly again because of the need for renewable fuels from biomass (DE WILD, 2015).…”

Waste to energy and materials through pyrolysis: a review

Waste biomass, such as agricultural waste, is emerging as a promising renewable energy resource because of its abundance and carbon-neutral nature. It has a high potential to be used as an alternative source of energy by employing thermochemical conversion techniques. Pyrolysis is the most efficient technique for the conversion of biomass-based waste in manufacturing renewable fuels and chemicals. However, despite pyrolysis being a well-known method to provide solid fuel (charcoal) and chemicals, the technological pathways for producing chemicals and liquid fuels at an industrial scale are not fully developed. This review addresses the relevance of pyrolysis for waste-to-energy and materials, the fundamentals of pyrolysis, different reactors, process conditions, and its products from the perspective of energy and materials recovery. Accordingly, the purpose of this review is to analyse the current application level of pyrolysis for waste management, identify gaps in our current understanding, and recommend future research directions.

“…Las biorrefinerías transforman la biomasa en bioproductos y energía mediante diferentes procesos y tecnologías, para el aprovechamiento integral de la materia prima y minimización de los residuos (Sadhukhan et al, 2014;Hassan et al, 2018;Temmes y Peck, 2020) De acuerdo con Moncada et al (2014), existen algunas clasificaciones para la biorrefinería, una de estas atiende a la materia prima que se emplea, y así clasificarlas de primera, segunda y tercera generación. La primera, emplea cultivos destinados a la alimentación, la de segunda generación emplea materiales lignocelulósicos foresto y agroindustriales, además de cultivos no comestibles (Cherubini, 2010), y por último, la de tercera generación, que utiliza algas y microorganismos (de Wild, 2015). El aprovechamiento de los residuos agroindustriales aporta soluciones enfocadas en problemáticas ambientales, generalmente causadas por la generación y disposición final de los mismos (Vargas Corredor y Peréz Pérez, 2018).…”

Los residuos agroindustriales presentan un alto potencial de aprovechamiento gracias a su composición química variada, lo que se evidencia en la diversidad de alternativas existentes para su posterior reutilización. En el presente estudio se propone el diseño de una biorrefinería con el empleo del bagazo de caña de azúcar como biomasa para la obtención de productos de segunda generación, planteándose alternativas que consideran el aprovechamiento del licor y residual sólido. Se empleó el programa SuperPro Designer® v.10e para realizar las simulaciones correspondientes y determinar los subproductos de mayor interés económico, con base en una comparación de indicadores, como: valor actual neto (VAN), tasa interna de retorno (TIR), período de recuperación de la inversión (PRI) y retorno de la inversión (ROI), proporcionados por el simulador. Los resultados obtenidos demostraron que la configuración xilitol-pellets es la más viable, considerando que a partir de una inversión inicial de USD $52.145.000, la biorrefinería obtuvo un VAN de USD $122.612.000, una TIR de 34,14 % y un PRI de 2,1 años. Además, se realizó un análisis de sensibilidad considerando los diferentes indicadores dinámicos, mediante la variabilidad del precio de venta unitario del xilitol. Finalmente, el análisis económico mostró la viabilidad de la producción de xilitol y pellets con bagazo de caña de azúcar
