Higher estimated imports for 2019/20 result in higher carryout, also boosting 2020/21 supplies. The stocks-to-use ratio for 2019/20 is estimated to be 14.5 percent and 13.5 percent for 2020/21. Mexico sugar production estimates are raised for 2019/20, increasing exports to the United States. Lower forecasted domestic deliveries in both 2019/20 and 2020/21 allow for more domestic supplies to be exported, with most of the increase in 2020/21 expected to go to non-U.S. destinations.

  • Sugarcane Outgrower Schemes in Mozambique: Findings from the Field
    Proceedings of the International Society of Sugar Cane Technologists, volume 29, 434-440, 2016 Sugarcane outgrower schemes in Mozambique: findings from the field JGDB Leite1,3, MRLV Leal2 and FM Langa4 ¹Interdisciplinary Center for Energy Planning (NIPE), University of Campinas (Unicamp) – Rua Cora Coralina 330 Campinas, SP, Brazil 13083-896 ²Brazilian Bioethanol Science and Technology Laboratory/National Research Center for Energy and Materials CTBE/CNPEM – P.O.

Box 181, Chapecó, SC, Brazil 89802-112; [email protected] 4Gwevhane - Xinavane, Maputo, Mozambique Abstract Agro-industries have been widely acknowledged as a way to kick-start agricultural development in developing regions. A number of pro-poor organizations promote production models that include the engagement of smallholder farmers as potential enablers for employment generation, economic development and livelihood improvements. Initiatives such as this appear in Sub-Saharan Africa with a focus on food and bioenergy crops. However, the large-scale production of cash crops, such as sugarcane, also raises concerns. A critical aspect is the impact of land- use on food security, particularly if local communities are constrained in cultivating traditional crops. In this paper, we explore the relationship between a sugarcane mill and smallholder farmers in Maputo province, Mozambique. Our main goal was to investigate some key characteristics of sugarcane outgrower schemes and the implications for sustainable local development. We also complemented local findings with lessons learnt from other regions, such as Brazil. In August 2015, a field assessment examined the interplay between the sugarcane industry and local communities in southern Mozambique.

The objective of this work was to perform a techno-economic assessment of vinasses treatment alternatives for valorization of this waste through process simulation with Aspen Hysys v10.0. Methods Four alternatives were studied: (A_1) incineration and electricity generation, (A_2) desalinization, (A_3) anaerobic digestion and electricity generation and (A_4) drying. The selected packages for the evaluation and prediction of properties were: Lee-Kesler-Plöcker and NBS Steam, NRTL-Ideal, Peng-Robinson-Stryjer- Vera and NBS Steam and NRTL-Ideal respectively; the validation in these cases was carried out with data reported in the literature. The economic evaluation was carried according to the changes that each alternative determines in each one of the elements of effective cash ow comparing with the actual condition.

Received: 15 May 2014; in revised form: 6 August 2014 / Accepted: 27 August 2014 / Published: 10 September 2014 Abstract: Worldwide energy policies are moving towards a reduction of fossil fuels’ share in the energy mix and to invest in renewable and green energy sources. Biomass is one of these, and it represents, in the form of sugarcane, a strategic source in Colombia, especially in the Valle del Cauca. In this region, the sugarcane industry is able to convert the energy content of the cane into different energy products, such as ethanol, electricity, and high-pressure steam, which are cogenerated via bagasse combustion. In this work, the case of a sucrose and ethanol production plant, which mills ten thousand tons of sugarcane per day, is considered. A tailor-made computational model was developed to assess the energy and material process balances in order to estimate the effect of different operating conditions on cogeneration boilers and turbines, and to optimize the overall process efficiency.

  • SUGAR CANE and RUM ROUTE of MADEIRA Madeira Island Porto Da Cruz ©Francisco Correia
    SUGAR CANE AND RUM ROUTE OF MADEIRA Madeira Island Porto da Cruz ©Francisco Correia Sugar cane is an agricultural product cultivated in Madeira since its colonization and which contributed for the exponential economic, social and cultural development of the island and of the then kingdom of Portugal, through the exports of one of its by- products – the sugar. HISTORICAL FRAMEWORK By order of Prince Henry, the Navigator, in the first quarter of the 15th century, the first sugar cane stalks (Saccharum officinarum), from Sicily, reached Madeira. Here they found fertile soils and abundant water, brought by the small levadas from the sources of the main streams. The places with a greater production of sugar cane and where most of the engenhos (sugarcane mill) could be found were located on the Southern slope of the island, namely in the municipalities of Funchal, Ribeira Brava, Ponta do Sol and Calheta. The first reference to Madeiran sugar dates back to 1433 and, two decades later, it was already produced in sufficient quantities for exportation, being considered the most refined sugar on the market. The Madeiran sugar was successful in the European market due to its quality, competing with the sugar from Sicily, Egypt and Morocco, and was exported to England, Flanders, France, Italy, Constantinople, among other markets. The sugar, also called “White Gold”, was exported inside a type of “cone” made out of clay, called “Pão de Açúcar” (Sugar Bread) or “Cones de Açúcar” (Sugar Cones).
