This comprehensive review aims to elucidate the state of the art related to research trends regarding the use of brewer's spent grains (BSG), the main solid by-product generated in breweries. Its status, future opportunities, and emerging trends were evaluated by bibliometric analysis, which contributed to clarifying the knowledge and perspectives in the field. In total, 510 documents were obtained from the Web of Science© database in a timespan from 1900 to 2020. VosViewer software and R-bibliometrix package were used to investigate and map the most frequently cited papers, international collaborative networks, keywords, and the main countries and journals associated with this research. The results showed that, globally, 65 countries have been engaged in research related to BSG, and Brazil has been the most productive country, with up to 70 publications. Keyword analysis revealed that the studies on BSG are divided into four main knowledge areas: (i) pretreatment; (ii) nutritional quality; (iii) bioactive compounds, and (iv) pyrolysis. It was also found that a biorefinery can be designed for the complete utilization of BSG to obtain several valuable compounds. In this sense, different technological routes can be applied to produce arabinoxylans, proteins, ferulic acid, xylitol, xylose, lactic acid, butanol, biogas, fertilizer, and ethanol. In conclusion, BSG is a cost-effective and feasible raw material for the sustainable production of bio-based products and bioenergy and its valorization in a biorefinery is a powerful strategy to promote the circular economy transition of the beer industry.

“…Depolymerization, fragmentation, and cross-linking are chemical mechanisms that occur during the process at specific temperature points, resulting in a different product state for lignocellulosic components, including cellulose and hemicellulose (solid, liquid and gas). Biochar and bio-oil are the solid and liquid products, whereas CO 2 , CO, H 2 , (collectively known as syngas) are evolved as the gaseous by-products (C 1 -C 2 hydrocarbons) [3]. Biochar is made in a different type of reactors, such as paddle kiln, bubbling fluidized bed, wagon reactor, and agitated sand rotating kiln.…”

“…The earliest known purpose for creating biochar was specifically for soil application such as carbon storage or sequestration in soil; improvement of soil performance such as increase in nutrient availability, reduction of compactness in soil, soil pH improvement; soil water filtration. Recent applications involve energy production, biochemical process stability and improvement, climate change mitigation, and construction additive [1][2][3]. The raw material determines carbonized organic matter properties and the operational parameters used during it production.…”

Biochar, or carbon obtained from biomass, is a particularly rich source of carbon created by thermal burning of biomass. There is a rise of interest in using biochar made from waste biomass in a variety of disciplines to address the most pressing environmental challenges. This chapter will provide an overview on the methods employed for the production of biochar. Biochar has been considered by a number of analysts as a means of improving their ability to remediate pollutants. Process factors with regards to biochar properties are mostly responsible for determining biomass production which is discussed in this present chapter. Several characterization techniques which have been employed in previous studies have received increasing recognition. These includes the use of the Fourier transform infrared spectroscopy and the Scanning electron microscope which duly presented in this chapter. This chapter also discusses the knowledge gaps and future perspectives in adopting biochar to remediate harmful contaminants, which can inform governmental bodies and law-makers to make informed decisions on adopting this residue.

Quantitative Low‐Field ¹⁹F Nuclear Magnetic Resonance Analysis of Carbonyl Groups in Pyrolysis Oils

et al. 2023

Pyrolysis bio-oils, one of the products of lignocellulosic biomass pyrolysis, have the potential to be widely used as fuels. The chemical composition of bio-oils is very complicated as they contain hundreds, if not thousands, of different, mostly oxygencontaining, compounds with a wide distribution of physical properties, chemical structures, and concentrations. Detailed knowledge of bio-oil composition is crucial for optimizing both the pyrolysis processes and for any subsequent upgrading into a more viable fuel resource. Here we report the successful use of low-field, or benchtop, nuclear magnetic resonance (NMR) spectrometers in the analysis of pyrolysis oils. Pyrolysis oils from four different feedstocks were derivatized and analyzed using 19 F NMR techniques. The NMR results compare favorably with titrations for total carbonyl content. In addition, the benchtop NMR spectrometer proves able to reveal key spectral features, thus allowing the quantification of different carbonyl groups, such as aldehydes, ketones and quinones. Benchtop NMR spectrometers are typically compact, cheaper than their superconducting counterparts and do not require cryogens. Their use will make NMR analysis of pyrolysis oils easier and more accessible to a wide range of different potential users.
