Drinking ten bathtubs of water a day
Published in Arjen Y. Hoekstra, The Water Footprint of Modern Consumer Society, 2019
A widespread problem related to sugar beet cultivation is eutrophication of water bodies due to the overuse of fertilizers (WWF, 2004). The nutrients in the fertilizers are not entirely taken up by the crop but partly leach to groundwater and flow into streams. The runoff of nitrate and phosphate into lakes and streams can contribute to a eutrophic status and the proliferation of toxic microalgae. In the Seine-Normandy Basin in France, irrigation has little quantitative impact on the resource, but does, however, have an indirect impact on its quality because it favours intensive farming techniques and spring crops, which leave the soil bare for long periods of the year and increase the chemical load in the rivers by leaching and draining (UNESCO, 2003). This has a harmful effect on both the environment and other water uses. Improving water quality is still a major concern for the basin, where non-point source pollution from farming and urban areas is still a major problem as nitrate, pesticides and heavy metals concentrations continue to increase.

Sugar beet, a biennial root vegetable, contains a high concentration of sucrose in its root. Although sugar beet can be grown in a wide variety of climates, it is most commonly grown in regions with temperate climates (Draycott, 2006). The average sugar (sucrose) content of sugar beet is around 17% of the total raw biomass, and the percentage can vary depending on the specific variety and growing conditions. In addition to sucrose, sugar beet also contains 75% water, 5% lignocellulosic materials, and 3% glucose and fructose (Cheesman, 2004). As of 2014, the world’s four largest sugar beet producers were France (37.6 million tons), Russia (33.5 million tons), Germany (29.7 million tons), and the US (28.5 million tons). Approximately one million acres of US cropland was used for sugar beet production (FAO, 2015).

Discovery of sucrose in sugar beets and the process for making sugar from sugar beets occurred in Europe in the 1700s, but its cost was not competitive with imported sugar from sugarcane. Napoleon, when cut off from sugar imports by the British blockade, banned sugar imports (interesting timing), which provided the economic impetus for advancing the technology to convert sugar beets to sugar. Sugarcane is grown in tropical and subtropical regions, whereas sugar beets are grown in temperate regions of the Northern Hemisphere. Sugar from sugarcane is cheaper than from sugar beets, even though sugar beets have a higher sucrose yield, because the process of separating sugar from sugar beets is more complicated. Sugar production is estimated to be 173.4 million metric tons for 2015/2016, down from a peak of 177 million metric tons in 2012/2013. Over 100 nations grow sugar, of which about 80 percent come from sugarcane and the remainder sugar beets. Figure 3.2 shows the world’s top 11 producers, accounting for 78 percent of world sugar production.
Simulation of mass transfer during sucrose extraction from sugar beet using a combined analytical and semi-empirical model

The root of the sugar beet plant (Beta vulgaris L.) contains a high content of sucrose, one of the economic products of sugar beet. For the past two centuries, sugar beet has been included in the human diet as a sweetener due to its high sucrose content (Trebbi and McGrath 2004). Moreover, sugar can be used as an additive in various foods and industrial products such as beverages, confectionery, detergents, and ethanol. Regarding the ever-increasing global sugar consumption, the demand for this ingredient has grown, making it one of the most popular international products (Asadi 2007; Dodić et al. 2012; Duraisam et al. 2017; Ellerton 2019; Mhemdi et al. 2014; Peris 2015). Sucrose is extracted from sugar beet tissues as one of the main stages of sugar production. The sugar extraction from beets relies on mass transfer from the solid matter to the liquid, due to the difference in the sugar concentrations of the solution and the plant cells (Duraisam et al. 2017).
Better Lime Purification of Raw Sugar Beet Juice by Advanced Fenton Oxidation Process

Conventional technology of sugar production from sugar beet processes consists of the next subsequent stages: thermal denaturation of the sliced beet roots followed by diffusion in hot water (70–75 °C), clarification of extracted juice by lime-carbon dioxide, several filtrations stage, sulfitation, concentration of purified juice and crystallization (Loginova et al. 2012). The purpose of the purification operation is to produce a clear juice with a low quantity of non-sugar impurities and dense mud from which most of the sucrose of a specified purity level can be extracted (Mhemdi et al. 2015).
Assessment of potential biomass energy production in China towards 2030 and 2050

AR include straw and stalk, which are the byproducts of agricultural cropping practice (cultivation of farms and harvesting activities) and the byproducts of processing agricultural crop products like food or feed production process. The crops cultivated on arable land can be classified into five categories, which are grain crops, oil content crops, cotton, fibre crops, and sugar crops. The grain crops include cereal crops (wheat, corn, and rice), beans, and tubers. Oil-containing crops include peanuts, rapeseed, sesame, and other oil crops. Sugar crops include sugarcane and sugar beet.
