Technological Improvements

There are still large differences in process steam consumption, sugar recovery and plant availability when comparing sugar production from beet versus that from cane on a global scale. These are partly due to higher sugar contents and purities of sugar beet, but also due to more developed process technologies enabling a more efficient usage of steam and energy. Specific areas of a cane factory that can benefit from adaption technologies typically employed in European beet sugar production are: heat-transfer equipment especially evaporators and condensers, sugar-house work including seed magma systems by cooling and improved crystallizer designs, close monitoring and reduction of water input at all stages of the process, modern layout of the plant in order to reduce pressure drops and enable good supervision, and efficient electrical drives and automation systems. As a result, the improved factories have been able to increase significantly sugar yield and cogeneration power for sale to the national grid and have an increased profitability. Some specific examples of the technological improvements and benefits obtained in some cane factories as a result of the above measures are presented. A further example of the possibilities to process sugarcane and sugar beet in a highly efficient dual-use plant is also shown. Due to the low process-steam consumption of the plant, enough surplus bagasse is produced during the cane crop in order to be self-sufficient in fuel during the beet crop.

To get more insight in the environmental performance of the Suiker Unie beet sugar, Blonk Consultants performed a comparative Life Cycle Assessment (LCA) study on beet sugar, cane sugar and glucose syrup. The system boundaries of the sugar life cycle are set from cradle to regional storage at the Dutch market. For this study 8 different scenarios were evaluated. The first scenario is the actual sugar production at Suiker Unie. Scenario 2 until 7 are different cane sugar scenarios (different countries of origin, surplus electricity production and pre-harvest burning of leaves are considered). Scenario 8 concerns the glucose syrup scenario. An important factor in the environmental impact of 1kg of sugar is the sugar yield per ha. Total sugar yield per ha differs from 9t/ha sugar for sugarcane to 15t/ha sugar for sugar beet (in 2017). Main conclusion is that the production of beet sugar at Suiker Unie has in general a lower impact on climate change, fine particulate matter, land use and water consumption, compared to cane sugar production (in Brazil and India) and glucose syrup. The impact of cane sugar production on climate change and water consumption is highly dependent on the country of origin, especially when land use change is taken into account. The environmental impact of sugar production is highly dependent on the co-production of bioenergy, both for beet and cane sugar.

A Site

This article examines the contrasting evolution in sugar refining in Jamaica and Barbados incentivized by Mercantilist policies, changes in labor systems, and competition from foreign sugar revealing the role of Caribbean plantations as a site for experimentation from the eighteenth through mid-nineteenth century. Britain's seventeenth- and eighteenth-century protectionist policies imposed high duties on refined cane-sugar from the colonies, discouraging colonies from exporting refined sugar as opposed to raw. This system allowed Britain to retain control over trade and commerce and provided exclusive sugar sales to Caribbean sugar plantations. Barbadian planters swiftly gained immense wealth and political power until Jamaica and other islands produced competitive sugar. The Jamaica Assembly invested heavily in technological innovations intended to improve efficiency, produce competitive sugar in a market that eventually opened to foreign competition such as sugar beet, and increase profits to undercut losses from duties. They valued local knowledge, incentivizing everyone from local planters to chemists, engineers, and science enthusiasts to experiment in Jamaica and publish their findings. These publications disseminated important findings throughout Britain and its colonies, revealing the significance of the Caribbean as a site for local experimentation and knowledge.

In pot and field tests MnSO4 and the frits FTE Z 4 (13 % Mn), HZ 1 (15.9 % Mn) and HZ 17 (21 % Mn) increased reducible soil Mn for at least 1 1/2-2 years. Mn content of pasture increased four-fold in the first cut after application of 400 kg/ha MnSO4 but sharply decreased in later cuts and became negligible by the second year. 400 kg/ha HZ 17 did not affect pasture Mn. In peas 400 kg of soil- or foliar applied MnSO4 controlled marsh spot better than 800 kg HZ 1; spraying at the middle and again at the end of the blooming stage gave the best control. With sugar beet, soil dressings of MnSO4, HZ 1 and HZ 17 equally increased yield, sugar production and leaf Mn, and decreased incidence of Mn deficiency. When the rates of these fertilizers were increased from 100, 179 and 86 kg respectively to 400, 714 and 343 kg, sugar production was not significantly improved; leaf Mn and incidence of deficiency symptoms responded to the higher Mn rates. Soil application was rather better than foliar treatment. No treatment controlled Mn deficiency throughout the entire season. The % of Mn-deficient plants was related, negatively, to leaf and reducible soil Mn, but not to yield. Soil-applied Mn did not control gray spot in oats or increase yields but sprayed Mn did.

Economic Criteria

Sugar is an important economic commodity that is produced and consumed around the world. The impacts of different production methods differ on social, economic and environmental aspects. This research focuses on the economic trade- offs in conventional, organic and Fairtrade sugarcane production in India and sugar beet production in the Netherlands. Previous research provides insights into single production methods, but a complete comparison between different production methods is currently lacking. Data was collected using both literature research and interviews in the Netherlands and India. After developing a Multi-Criteria Analysis, it is concluded that organic sugarcane and Fairtrade sugarcane rank slightly higher than conventional sugarcane on the economic criteria. However, conventional sugar beet and organic sugar beet rank higher on all economic aspects, with conventional sugar beet ranking the highest. The main differences between the production methods can be seen in the innovation, and to a lesser extent the in the production.

Introduction. Technological aids play a special role in sugar production technology, but their complex effectiveness requires a comprehensive and in-depth study. The research objective was to establish the patterns of change in the technological indicators of semi-finished products obtained from bacterially infected sugar beets with the combined use of an enzyme preparation, antimicrobial agent, and defoamer. Study objects and methods. The study involved such semi-finished products as juice (diffusion, pre-defecated, first and second saturation) and syrup, the quality of which was determined according to standard methods. The laboratory experiment was carried out on the basis of the second-order D-optimal Box-Behnken plan for three factors at three levels. Results and discussion. The research revealed positive dynamics of the following technological indicators: sucrose content, deposition rate, turbidity, chromaticity, and general purification effect. The sugar beet had the second degree of infection with mucous bacteriosis. Purified juice underwent lime-carbon dioxide purification and thickening under the combination of enzyme preparation Dextrasept 2, antimicrobial agent Betasept, and antifoam agent Voltes FSS 93. The greatest increase in sucrose at the level of 1.1% by DM weight was confirmed by a higher overall effect of purification of diffusion juice (2.2 %). The values of turbidity of the purified juice and syrup were below the threshold values. The low values resulted from the increase in the sedimentation rate of the pre-defective juice and the juice of the first saturation by an average of 4.1 and 3.2 times, respectively, due to the effective removal of high molecular weight compounds. The share of the enzyme preparation was 40–71%, antimicrobial agent – 19–49%, defoamer – 1.6–6.5%. The values of the multicriteria optimization parameter corresponded with technological indicators. The optimal combination (per 1000 tons of beets) included 6–8 kg of Dextrasept 2, 1.5–2.0 kg of Betasept, and 15–20 kg of Voltes FSS 93. As a result, the yield of white sugar increased by 0.25%. Conclusion. The regression dependencies can be recommended for predicting the main technological indicators of semi-finished products. The resulting data makes it possible to determine the effectiveness of the combined use of an enzyme preparation, antimicrobial agent, and defoamer in sugar production. Further research will identify the patterns of multifactorial interaction of these preparations.

Beet sugar production is one of the material-intensive industries, where the volume of raw and auxiliary materials used in production is several times higher than the output of finished products. It is also a source of multi-tonnage secondary resources, i.e. by-products and production waste, the main ones beingAbeet pulp, molasses and filtration sludge. Against the background of the implementation of the Sectoral Program of Beet Sugar Production Development in the Republic of Kazakhstan for 2018-2027, there is a need to create a concept of ecologization of production, which will provide for the development of fundamentally new technologies to ensure minimum waste, combining environmentally friendly methods with cost-effective production of sugar beet and by-products. The bet should be made on low-cost technologies that will minimize production costs and environmental impact. In this article possible variants of sugar beet processing technologies with complex deep processing of waste are offered. The comparison of traditional technology and various variants of progressive technologies of sugar beet processing and production of new products from secondary resources was carried out, which allowed to determine revenue from complex processing of 1 ton of sugar beet.

First Time

The first research project in medieval industrial archaeology in Cyprus originated with the investigation of the Lusignan cane sugar production centre at Kouklia (Stavros Project); it became an incentive for the exploration of the establishments of the Hospitallers at Kolossi and the Cornaro family at Episkopi. Excavations at Kouklia-Stavros (1980–82 and 1987–91) recovered a sophisticated structure of milling and refining installations, and revealed new economic and technological aspects of this important, but thus far hardly explored industry of the island in Lusignan and Venetian times. The wealth of new information gained made it possible to understand for the first time thoroughly how Levantine cane sugar refineries actually worked. The contextual approach of the Stavros Project, interrelating archaeological evidence and written information, suggests further interesting research topics such as the repercussions of the sugar industry on social structure, settlement patterns, and environment, or the transfer of the methods and technology of sugar production from Islamic lands to the western Mediterranean, and finally to the Americas.
