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.

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.

Cane sugar production is an important industrial process. One of the most important steps in cane sugar production is the clarification process, which provides high-quality, concentrated sugar syrup crystal for further processing. To gain fundamental understanding of the physical and chemical processes associated with the clarification process and help design better approaches to improve the clarification of the mixed juice, we explore the fractal behavior of the variables pertinent to the clarification process. We show that the major variables in this key process all show persistent long-range correlations, for time scales up to at least a few days. Persistent long-range correlations amount to unilateral deviations from a preset target. This means that when the process is in a desired mode such that the target variables, color of the produced sugar and its clarity degree, both satisfy preset conditions, they will remain so for a long period of time. However, adversity could happen, in the sense that when they do not satisfy the requirements, the adverse situation may last quite long. These findings have to be explicitly accounted for when designing active controlling strategies to improve the quality of the produced sugar.

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.

By the end of the nineteenth century and beginning of the twentieth, two islands had come to dominate global cane-sugar production. For most of the sixty-year period between 1870 and 1930, around half of the world's internationally traded crop came from Cuba and Java. The two islands had many topographical similarities that made them particularly well suited to the establishment of sugar plantations: both are relatively large islands with fertile soils and semi-tropical climate. They were also situated in regions that had been drawn into the European sphere of influence in the sixteenth century but that had only been lightly exploited before the nineteenth, when they were both well placed to assume leading roles in the satisfaction of the escalating demand for sugar in the industrialising societies of Europe and North America.However, Cuba and Java existed within two very distinct sets of imperial and commercial networks: Spanish and Atlantic, and Dutch and Indian Ocean respectively. As a result of this, while there have been a plethora of studies about cane agriculture and the sugar industry in each of the islands, there has been little effort to compare their histories or explore the interconnections between them. Only recently has a start been made to study systematically the “convergence and divergence” of the sugar industry in the two hemispheres and to compare the differences and similarities to be found in the paths followed by the two islands.Although the sugar industries of Cuba and Java took different directions, these were inextricably linked. While Cuban planters could exploit the availability of large areas of underused land to overcome the relative scarcity of labour, planters in Java took advantage of the relative abundance of labour to maximise yields from the more limited land available to them. As a consequence of this, Javanese planters influenced by the work of Cuban agronomist Álvaro Reynoso paid considerable attention to the development of scientific methods in cane cultivation. Meanwhile, Reynoso's ideas fell on deaf ears in his home island, where most planters ignored the need for a more scientific approach in the fields in favour of technological advances in the sugar factory and what they saw as their immediate commercial interests.

In cane sugar production field, there are a few indexes should be highlighted, which are the product quality, refining efficiency, sugar boiling time and heat transfer performance. And those indexes are all related to the massecuite circulation flow. With the goal of better sugar production, this paper developed a model for optimal global coordination of all the sugar boiling facilities based on the multiple coupling synergies of the sugar boiling system. With a synergy solver developed by knowledge base and data base, the model solution was yielded. Emulation and experimental results showed that the higher synergy of all multiple fields, the better was the massecuite circulation flow. In other words, the optimal solution this paper yielded could result the higher production of sugar and more identical size of the sugar crystals.
