“…Brewer's spent grain has recently been used with a maximum adsorbed amount of methylene blue of 284.75 mg/g at pH = 11.0. A possible adsorption mechanism involves electrostatic interaction, electron donors and electron acceptors, hydrogen bonds and π-π dispersion [133]. Biomass obtained from weeds (Cyanthilium cinereum and Paspalum maritimum) was also evaluated to eliminate this dye, the maximum absorption capacities obtained were 56.18 and 76.34 mg/g, respectively [134].…”

“…Thus, the removal of tartrazine yellow was evaluated using brewer's spent grain as biomass; the maximum adsorbed amount was 26.18 mg/g at pH = 2.0. This adsorption involves electrostatic attraction, π-π interaction and multilayer formation of dye [133]. Reactive Blue 19 using dead biomass of the brown marine alga Bifurcaria bifurcata, with a maximum adsorbed amount of 88.7 mg/g in only 15 min at pH = 1.0.…”

Biosorption is a variant of sorption techniques in which the sorbent is a material of biological origin. This technique is considered to be low cost and environmentally friendly, and it can be used to remove pollutants from aqueous solutions. The objective of this review is to report on the most significant recent works and most recent advances that have occurred in the last couple of years (2019–2020) in the field of biosorption. Biosorption of metals and organic compounds (dyes, antibiotics and other emerging contaminants) is considered in this review. In addition, the use and possibilities of different forms of biomass (live or dead, modified or immobilized) are also considered.

“…Research shows that BSG after saturation of the active sites with hydrogen cations could, with good effectiveness, adsorb the copper [ 45 ] or other heavy metals [ 46 ] cations from water solutions. Dyes could also be removed by using a BSG as a cheap and eco-friendly biosorption material [ 47 , 48 ]. Moreover, It could be transformed into a magnetic form by a treatment, using perchloric acid stabilized magnetic fluid containing iron oxide nanoparticles [ 48 ].…”

Brewer’s Spent Grains—Valuable Beer Industry By-Product

et al. 2020

The brewing sector is a significant part of the global food industry. Breweries produce large quantities of wastes, including wastewater and brewer’s spent grains. Currently, upcycling of food industry by-products is one of the principles of the circular economy. The aim of this review is to present possible ways to utilize common solid by-product from the brewing sector. Brewer’s spent grains (BSG) is a good material for sorption and processing into activated carbon. Another way to utilize spent grains is to use them as a fuel in raw form, after hydrothermal carbonization or as a feedstock for anaerobic digestion. The mentioned by-products may also be utilized in animal and human nutrition. Moreover, BSG is a waste rich in various substances that may be extracted for further utilization. It is likely that, in upcoming years, brewer’s spent grains will not be considered as a by-product, but as a desirable raw material for various branches of industry.

“…According to recent reports [ 6 ], the worldwide annual production of beer is 1.9 billion hectoliters and considering that about 20 kg of BSG is produced for every beer hectoliter, a production of around 39 million tons of BSG is esteemed, 3.4 million tons of which are from the European Union. In the last few years, the upcycling of BSG has become a widespread practice for the multiple possibilities of reuse as a sorption material [ 7 , 8 , 9 , 10 ], and as a fuel after proper treatments [ 11 ] for use in animal [ 11 , 12 , 13 , 14 ] and human nutrition [ 15 , 16 , 17 , 18 ]. The high interest in these by-products is currently making BSG a profitable raw matter for several industrial fields [ 19 ].…”

Brewer’s spent grains are one of the principal by-products of the brewing industry. For protein and fibre content, this by-product represents an interesting raw material to be reused for manufacturing many other products. To maximize the nutritional characteristics of this by-product, in this study, ingredients derived from brewer’s spent grains were included in the design of innovative dry pasta. Two brewer’s spent grains derivative ingredients, one enriched in proteins and the other in fibre were blended with semolina. Based on the rheological evaluation, the optimal amount of the two ingredients for producing pasta was determined. In particular, pasta responding to the claims “High Protein” and “High Fibre” was realized using the formulation enriched with 15% of protein-rich ingredient and the claim “High Fibre” and “Source of proteins” using the formulation enriched with 10% of fibre-rich ingredient. The final products were compared to 100% semolina and 100% wholegrain semolina pasta for composition, color, texture, and cooking quality, revealing excellent quality characteristics. The newly formulated pasta represents a successful match of technological aptitude, nutritional/sensorial quality, and sustainability.
