Beet Pulp

The sugar beet industry produces considerable amounts of organic waste and by-products. Sugar beet pulp (SBP) is the residue that remains after sugar extraction. SBP is a lignocellulosic by-product of the sugar industry and generally used as animal feed at relatively low price. Instead of cattle feeding, SBP can be used as a raw material for industrial applications because it is low-cost and available in large amounts. Biomass is a clean and renewable energy source. The use of SBP for the production of ethanol, methanol, single cell protein, biofuels etc. is economically very attractive. This literature review evaluates the use of SBP as biomass.

Liquefaction Process

Abstract Liquefaction of sugar beet pulp (SBP) was carried out using microwave irradiation as the heating source, ethylene glycol/glycerol at a ratio of 80/20 (w/w) as the liquefaction solvent and sulfuric acid as the catalyst at 160 °C. The effects of different liquefaction conditions, including two particle size ranges of SBP, liquefying solvent-to-SBP solids (LS/S) ratio and reaction time on the liquefaction yield, viscosity of the liquefaction products, chemical characteristics and morphology of residues were studied using viscometry, Fourier transform infrared (FTIR), X-ray diffraction (XRD), scanning electronic microscopy (SEM). The efficiency of liquefaction of SBP was found to depend on its particle size of SBP raw material and the LS/S ratio. The smaller SBP particles improved liquefaction efficiency and reduced the amount of solvent required. The crystallinity index of liquefaction residues indicated that crystalline cellulose was no longer the rate limiting factor of liquefaction process when the particle size of SBP was small (75–177 μm). A rugged and deformed surface of the liquefaction residue (observed through SEM) indicated that severe damage in the native fiber structure occurred during the liquefaction.

Over 8 million tonnes of sugar beet are grown annually in the UK. Sugar beet pulp (SBP) is the main by-product of sugar beet processing which is currently dried and sold as a low value animal feed. SBP is a rich source of carbohydrates, mainly in the form of cellulose and pectin, including d-glucose (Glu), l-arabinose (Ara) and d-galacturonic acid (GalAc). This work describes the technical feasibility of an integrated biorefinery concept for the fractionation of SBP and conversion of these monosaccharides into value-added products. SBP fractionation is initially carried out by steam explosion under mild conditions to yield soluble pectin and insoluble cellulose fractions. The cellulose is readily hydrolysed by cellulases to release Glu that can then be fermented by a commercial yeast strain to produce bioethanol at a high yield. The pectin fraction can be either fully hydrolysed, using physico-chemical methods, or selectively hydrolysed, using cloned arabinases and galacturonases, to yield Ara-rich and GalAc-rich streams. These monomers can be separated using either Centrifugal Partition Chromatography (CPC) or ultrafiltration into streams suitable for subsequent enzymatic upgrading. Building on our previous experience with transketolase (TK) and transaminase (TAm) enzymes, the conversion of Ara and GalAc into higher value products was explored. In particular the conversion of Ara into l-gluco-heptulose (GluHep), that has potential therapeutic applications in hypoglycaemia and cancer, using a mutant TK is described. Preliminary studies with TAm also suggest GluHep can be selectively aminated to the corresponding chiral aminopolyol. The current work is addressing the upgrading of the remaining SBP monomer, GalAc, and the modelling of the biorefinery concept to enable economic and Life Cycle Analysis (LCA).

The purpose of the work was to study the suitability of residue obtained during the methane fermentation process of sugar beet pulp for agricultural use in sugar beet plantations. Studies were performed with the sugar beet pulp fermentation residue and sugar beets (Beta vulgaris cv. Fighter) harvested from experimental plots. It was found that the by-product of sugar beet pulp digestion may be utilized in agriculture taking into account its chemical and microbiological standards. The nutrients in digestion residue were as assimilable for sugar beet plants as the nutrients in mineral fertilizers. The evaluation of technological parameters of sugar beet harvested from experimental plots based on standard technological criteria showed that irrespective of fertilization treatment, the raw material obtained met most of the requirements and can be used as a stock material for sugar production.

The primary objective of this paper is to identify the possibilities of using sugar beet pulp as feedstock to produce a variety of added-value products. Such an application of the sugar production byproducts contributes to implementing circular bio-economy, which is a source of many economic, social, and environmental benefits. Specific objectives of this paper are: (1) Presenting the concept and meaning of circular bio-economy. (2) Characterizing properties of the sugar beet pulp from the perspective of using them as feedstock. (3) Determining the volume of production of the sugar beet pulp and the current methods of using them. (4) Determining the methods of obtaining attractive bioproducts and renewable energy from sugar beet pulp. Special attention was given to the amount of sugar beet pulp produced in Polish sugar refineries. Poland is among the European countries in which the volume of produced sugar is especially high. Therefore, the problem of appropriate waste management in the Polish sugar industry gains significant importance. The conducted literature review demonstrated that sugar beet pulp might be used as a feedstock in the production of many bio-products produced using a variety of methods.
