The sugar beet pulp from the sugar production is, thanks to the easily assimilable carbohydrate content, an important source of feed, especially for polygastric animals. Its efficiency in terms of assimilation and biological effect can be substantially improved by the addition of macroelements (Ca, Mg, P) and microelements (Zn, Co, Fe, Mn, Cu). These elements react with the sugar beet pulp compounds to form specific chelates. In order to preserve and maintain the nutritional value of the premix, the realization process involves a drying operation. In view of this, experiments have been carried out to determine the maximum moisture content that ensures preservation and optimum drying conditions. This paper presents how the percentage of micro-and macro-elements used and the drying temperature influence the drying speed of the premix

The Uk

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).

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.

In accordance with Nordzucker’s energy policy, Nordzucker has launched two projects to exploit the energy potential in side streams from sugar production: 1 Enhanced biogas production from anaerobic wastewater treatment with enzymatically hydrolyzed sugar beet pulp 2 Biogas production from tops and tails Before the two projects were started, the biogas potential in beet pulp and tops and tails was tested at Teknologisk Institut, Aarhus, Denmark. The biogas potential in both beet pulp and tops and tails was almost at the same level namely 324 and 313m3 (S.T.P.) CH4/t VSS (volatile suspended solids) respectively. The test also showed that app. 90% of the biogas was realized after app. 9 days. After 35 days, the degradation was completed.

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.

Lactic acid is a high-value molecule with a vast number of applications. Its production in the biorefineries model is a possibility for this sector to aggregate value to its production chain. Thus, this investigation presents a biorefinery model based on the traditional sugar beet industry proposing an approach to produce lactic acid from a waste stream. Sugar beet is used to produce sugar and ethanol, and the remaining pulp is sent to animal feed. Using Bacillus coagulans in a continuous fermentation, 2781.01 g of lactic acid was produced from 3916.91 g of sugars from hydrolyzed sugar beet pulp, with a maximum productivity of 18.06 g L−1h−1. Without interfering in the sugar production, ethanol, or lactic acid, it is also possible to produce pectin and phenolic compounds in the biorefinery. The lactic acid produced was purified by a bipolar membrane electrodialysis and the recovery reached 788.80 g/L with 98% w/w purity.

Beet Pulp

An effective and ecological method for liberation of pectin-derived oligosaccharides (POS) from sugar beet pulp (SBP) was developed using enzymatic and microorganism-mediated biomass conversion. The POS may be applied in the production of prebiotic feed additives. Various yeast strains were screened for their capacity for protein synthesis and monosaccharide assimilation. Combined yeast cultivation and pectin hydrolysis were found to be an effective method of producing prebiotics. Separate enzymatic hydrolysis and fermentation of SBP resulted in the release of 3.6 g of POS per 100 g d.w., whereas the yield of POS acquired after the combined process was 17.9% higher, giving 4.2 g of POS per 100 g d.w. Introducing the yeast into the process improved hydrolysis performance due to lower enzyme inhibition by mono- and disaccharides. The prebiotic effect of the POS was assessed by in vitro fermentation using individual cultures of gastrointestinal bacteria. The POS in the SBP hydrolysate effectively promoted the growth of lactobacilli and bifidobacteria. A large increase in adherence to Caco-2 cells in the presence of POS was noted for beneficial Lactobacillus brevis strains, whereas pathogenic bacteria and yeast (C. albicans, C. lusitanie, C. pelliculosa), responsible for infections in breeding animals, showed much weaker adhesion.
