Global value chains and world trade: Prospects and challenges for Latin America

Foreword by Alicia Bárcena.

Latin America and the Caribbean in the World Economy 2014: Regional integration and value chains in a challenging external environment

The 2014 edition of Latin America and the Caribbean in the World Economy: Regional integration and value chains amid challenging external conditions has four chapters. Chapter I examines the main features of the international context and their repercussions for world and regional trade. Chapter II looks at Latin American and Caribbean participation in global value chains and confirms that the region, with the exception of Mexico and Central America, has only limited linkages with the three major regional value chains of Asia, Europe and North America. This chapter also looks at how participation in value chains may contribute to more inclusive structural change, by analysing three core microeconomic aspects. Chapter III identifies various spheres in which regional integration and cooperation can help strengthen production integration between the economies of Latin America and the Caribbean. The fourth chapter explores the intra- and extraregional trade relations of the countries of the Caribbean Community (CARICOM) and considers how to strengthen production integration in the subregion by taking advantage of linkages beyond trade and building on commercial and production complementarities among the members. The chapter also reviews the differences between the countries in terms of income, population and production and export structure, in a context of marked macroeconomic vulnerability.

Efficiency: a key ingredient towards sustainable supply chains

This edition of the FAL Bulletin aims to help industry and policy makers see and embrace the direct link between sustainability and efficiency, so that action to make supply chains and businesses more efficient and sustainable can be taken.

Rising concentration in Asia-Latin American value chains: Can small firms turn the tide?

Dynamic Asia has overtaken the European Union as Latin America and the Caribbean’s second largest export market, after the United States. However, the region’s exports to Asia remain concentrated in few commodities involving a small number of large firms. This book explores the present and future scope for the participation of small and medium-sized enterprises (SMEs) in biregional trade and value chains and the measures that can be taken to make those chains more inclusive and sustainable. SMEs have a low direct presence in the region’s export flows and their participation in the supplier networks of multinational companies is weak. This volume reviews several supplier development programmes (SDPs) adopted in various countries in Asia and Latin America to increase SME linkages with multinational firms. These programmes, many of which are public-private initiatives, aim to boost SME productivity and enhance their participation in value chains.

Heavy mineral as a tool to refine the stratigraphy of kaolin deposits in the Rio Capim Area, Northern Brazil

Estudos de minerais pesados provenientes em depósitos cauliníticos da Formação Ipixuna na região do rio Capim (Brasil) revelaram uma mineralogia matura a supermatura, representada dominantemente por zircão e turmalina e, subordinadamente, rutilo, cianita e estaurolita. Os minerais encontrados não variam muito, entretanto cada unidade caulinítica apresenta uma assinatura particular definida por diferenças nasproporções entre os principais minerais, assim como em suas características texturais. Este trabalho demonstrou que asunidades de caulim soft (inferior) e semi-flint (superior) podem ser consideradas seqüências deposicionais distintas. As altas percentagens de opacos em relação aos minerais transparentes e altos teores de zircão são diagnósticos da unidade caulinítica inferior. O incremento no volume de grãos de zircão e turmalina arredondados a subarredondados na unidade caulinítica superior sugere que esta inclui grãos que foram submetidos a um grau mais elevado de retrabalhamento. O aumento no volume de grãos não alterados de estaurolita e cianita na unidade superior leva a concluir que, além da reciclagem sedimentar, uma fonte distinta deve ser invocada. Estes resultados também mostram que as características da assembléia de minerais pesados da unidade intermediária são comparáveis com aqueles da unidade superior, o que sugere mesmo posicionamento estratigráfico.

Application of bauxite waste from amazon region in the heavy clay industry

In this work, a method was developed for the application of red mud, an alkaline leaching waste, from a bauxite processing plant located in northern Brazil (Amazon region) as starting material for heavy clay products. Samples were prepared by pressing blends of red mud and clay, which were then fired at temperatures from 900 ºC to 1190 ºC. Characterization was carried out by chemical analysis, differential thermal analysis (DTA) and X-ray diffraction (XRD), and the following ceramic properties were evaluated: water absorption, linear shrinkage and flexural strength. In order to evaluate the Na⁺ stability in the dense ceramic, leaching tests were also carried out on the specimens after sintering process. Results indicated that samples with 50 and 70 wt% of red mud are proper for being used in the production of ceramic bodies, due to its excellent properties, mainly high mechanical resistance and low water absorption, showing thus, an option to minimizing the environmental impacts caused by the aluminum industry.

Desorption of heavy metals from ion exchange resin with water and carbon dioxide

Adsorption and regeneration of ion exchange resins were studied using a subcritical solution of a CO₂-H₂O mixture and a fixed bed column. The commercial Amberlite IRC-50/IRC-86 cation exchange resins and Amberlite IRA-67 anion exchange resin were tested for heavy metals (Pb, Cu, Cd) adsorption from a solution with different initial metal concentrations at different temperatures. After adsorption, the loaded resins were regenerated with water and carbon dioxide at different temperatures and a pressure of 25 MPa. The efficiency of the IRC-50 resin was lower than that of the IRC-86 resin for the adsorption of metals like Cd, Cu and Pb. Results obtained for desorption of these metals indicated that the process could be used for Cd and in principle for Cu. Sorption of metal ions depended strongly on feed concentration. Mathematical modeling of the metal desorption process was carried out successfully as an extraction process. For this purpose, the VTII Model, which is applied to extraction from solids using supercritical solvents, was used in this work.
