White Sugar

The main aim of this paper is to discuss the current state of knowledge on the chemical composition of floc isolated from acidified sugar solutions and explain the mechanism of its formation. The literature data shows that depending on the raw material used for the production of white sugar, i.e. sugar beet and sugarcane, the chemical composition of floc is different. The presence of polysaccharides i.e. dextran or levan in floc is a consequence of microbial activity. Therefore, it cannot be explicitly assumed that the origin of individual ingredients of floc is only the raw material, i.e. beets or sugarcane. Taking into account the literature data concerning the chemical composition of floc, it seems reasonable to link the direct impact of microbial biofilms present in sugar industry installations to the tendency of the final product to create floc. Currently, the basis for assessment of the proneness of sugar to create floc is the result of a 10-day test (ICUMSA Method GS2/3-40A). From the perspective of both producers and consumers of sugar, there is a need to develop and validate quick methods for assessing the tendency of sugar to create floc. This task is only possible to complete, when the mechanism of floc formation is fully explained.

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.

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.

With the liberalization of the European sugar sector, the industry is free to export sugar to the world market, competing with other sugarcane producing countries. To understand competitiveness, it is imperative to compare total production costs, including both raw material (farm) and processing costs (mill). Therefore, farmlevel production costs from agri benchmark combined with an engineering approach to calculate processing costs were merged to calculate sugar production costs in Germany and Brazil. The necessary data related to investment costs and technical coefficients was obtained in collaboration with BMA. Results show that processing one ton of white sugar (excluding raw material costs) from sugarcane in Brazil is more than USD30/t cheaper than processing sugar beet in Germany. Including raw material costs and the sales of byproducts, white sugar production in Brazil has a total cost advantage of USD112/t over German factories. Key differences in production costs are associated with labor (20%), depreciation (20%) and energy costs (40%). The findings indicate that even with equivalent raw material costs, the lower net processing costs are a major competitive advantage for Brazilian sugar producers. The combination of the typical farm approach and the dynamic engineering model can be applied to other regions, allowing for the estimation of regional production and shifts in global sugar supply.

Poland is one of the leading producers of sugar from sugar beet in Europe. However, the production of sugar generates large amounts of lignocellulosic waste, in the form of beet pulp and leaves. Currently, this waste is not reutilized in the chemical industry, but is only used as food for farm animals. This paper assesses the potential of using bio-waste from the sugar industry as a raw material for the production of furfurals via acid hydrolysis. Further processing of furfural into derivatives such as furfuryl alcohol (FA) or tetrahydrofurfuryl alcohol (THFA) could increase the economic profitability of the initiative. Furfuryl alcohol can be used as a fuel additive in sugar factories. Tetrahydrofurfuryl alcohol can be used as a component in agricultural fertilizers, increasing the yield of sugar beet. This approach reduces the amount of post-production waste and brings the sugar industry closer to the concept of a circular economy.

The relevance of the topic of the article is related to the need to develop agricultural markets at the regional level in order to increase the export potential of agricultural products. The purpose of the article is to find out the reasons for the decrease in the market price for sugar beet processed products, in particular white sugar, as well as to develop recommendations for optimizing the production and sale of sugar beet. The novelty of the study is to identify trends in the development of the market for raw materials for sugar production from sugar beets at the regional level and justification of the necessary priority measures to increase economic efficiency in the beet industry. The article presents the results of an analysis of the level of development of the commodity market for sugar producers. Priority directions for increasing production volumes and increasing the efficiency of sugar beet production as the main raw material for the production of white sugar and granulated sugar have been identified; recommendations have been given on ensuring sustainable growth in income from the sale of sugar beet root crops. The practical significance of the research results lies in the possibility of their use in the development of programs for the development of regional food markets, organizational, economic, technological measures to improve the efficiency of beet production in individual municipal areas to achieve high target indicators.

Pulp Production

The use of recovered paper as a raw material for paper production is by far the most economical and ecological strategy for the disposal of waste paper. However, paper production from recovered paper furnish generates a great amount of residues, and the higher the demand requirements for the end product, the higher the amount of rejected material. The reason for this is that the selectivity of the deinking process is limited; therefore, some valuable components are also lost in reject streams. The rejection of usable components affects the economics of recycled paper production. As the cost of waste disposal continues to increase, this issue is becoming more and more severe. This paper summarizes the current state of the resource efficiency in recycled pulp production and provides information on the volumes of rejected streams and the usable material within them. Various means to use these reject streams are also discussed, including the main findings of a recent thesis by the main author. This review summarizes current internal and external use of reject streams generated in the deinking operations.

In this research paper, development of a procedure of isolation of exopolysaccharides from frost-damaged beet and an analysis of structural and chemical composition of polymers isolated from sugar beet of different origin are presented. Total acid hydrolysis degradation integrated with HPAEC-ED analysis has been utilized to confirm the monomeric composition of the separated polysaccharides. The implementation of NMR spectral analysis and SEC chromatography of the structure of exopolysaccharides has been investigated. The results demonstrate that the chemical composition and structure of exopolysaccharides depend on their origin. Typical exopolysaccharides from Central European beet roots consist mainly of glucose monomers – and they have low branched structure – about 90% of α-1,6 linkage which is typical for dextran. The exopolysaccharides isolated from Swedish beet are characterized by 50–60% fructose monomers. They contain only about 65% α-1,6 linkages. Exopolysaccharides extracted from various origin beet differ in average molecular mass. The molecular distribution is not normal.

White Sugar

The bought sugar in the processed raw material (either beet or cane) comprises a high financial value and may contribute to somewhere around 50% of the white sugar production costs. It is therefore of the utmost importance to minimize sugar losses along the process and produce as much white sugar as possible from the raw material. This paper explains the principle of technical accounting as tool to control sugar extraction and losses in beet sugar manufacture. The sugar mass balance used to calculate the overall sugar extraction yield, as well as several simple calculations proposed for estimating the different sugar losses (like e.g. extraction (diffusion) losses, infection losses, sugar losses in molasses, etc.) in the subsequent process steps will be explained in detail. Proper technical accounting is considered indispensable for continuous process control and process improvement in pursuit of best-practice operation and cost-leadership.

AbstractThe effect of marine calcite, a mixture of ortho- and polysilicic acid as well as orthosilicic acid applied as a foliar spray on the chemical composition of sugar beet leaves in the critical phase of nutrient supply (beginning of July) but also leaves and roots during harvest time in 2015–2016, was studied. The content of silicon in the leaves ranged from 1.24 to 2.36 g kg−1 d.m. at the beginning of July, 3.85–5.34 g kg−1 d.m. during harvest and 2.91–4.20 g kg−1 d.m. in the roots. The foliar application of silicon caused a significant increase in the content of magnesium and calcium in leaves (in July) as compared to the control. The sugar beet consumes approx. 75 kg Si ha−1, which is almost 3.5 times more than P and 20% more than Mg thus proving its importance for its species. About 70% of the silicon taken up by sugar beet is stored in roots and 30% in leaves. The pure sugar yield is most favorably influenced by two- and threefold foliar application of the product containing silicon in the form of orthosilicic acid stabilized with choline, and a threefold mixture of ortho- and polysilicic acid. The increase in the pure sugar yield is not the result of a change in the chemical composition of sugar beet plants, but their more efficient functioning after foliar application of silicon under stress conditions caused by water shortage.
