Cargill process

A few complete process descriptions going from LA to polylactide can be found in the literature, for instance, the Cargill process [79], the Inventa Fisher process [80], and the Boehringer process [81]. However, most references are found on new scientific results and detailed process improvements, which will be discussed in the following sections. 

The impact of the complete Cargill process on the environment has been assessed, taking into account com production, monomer production and polymerisation. The energy consumption amounts to 54MJ/kg PLA, and produces 1.8 kg C02-equivalents/kg PLA (Vink, 2003). The Dow Cargill process consumes 20-50% less fossil fiiel compared to the production of comparable petroleum-based products. Finally, poly(lactide) is degraded into... 

Production of lactide from corn according to the Dow-Cargill process. 

Polyester chemistry is the same as studied by Carothers long ago, but polyester synthesis is still a very active field. New polymers have been very recently or will be soon commercially introduced PTT for fiber applications poly(ethylene naph-thalate) (PEN) for packaging and fiber applications and poly(lactic acid) (PLA), a biopolymer synthesized from renewable resources (corn syrup) introduced by Dow-Cargill for large-scale applications in textile industry and solid-state molding resins. Polyesters with unusual hyperbranched architecture also recently appeared and are claimed to find applications as crosstinkers, surfactants, or processing additives.

Based on the experience of those who have successfully implemented HACCP systems, this book will meet the needs of food processing businesses at all stages of HACCP system development. The collection is edited by two internationally recognised HACCP experts and includes chapters reflecting the experience of both major companies such as Cargill, Heinz and Sainsbury and the particular challenges facing SMEs. The scope of the book is truly international with experiences of HACCP implementation in countries such as Thailand, India, China and Poland. 

Economies of scale are important, especially as the big com processing companies such as A.D.M.Cargill and Staley are in close competition.

Much has been written about Cargill Dow LLC s polylactide (PLA) polymer, also known as NatureWorks PLA. PLA is a thermoplastic produced from biomass sugars by fermentation. The fermentation product, lactic acid, is converted into a lactide that is purified and polymerized using a special ring-opening process (18).

For the last 70 years or so the chemical industry has been based on crude oil (petroleum) and natural gas as basic raw materials, hence the name petrochemicals. This may not be so for much longer, however. The chemical industry is currently on the brink of a new revolution, based on the switch from fossil resources to renewable agriculture-based raw materials. From a distance the production facility of Cargill in Blair, Nebraska looks very much like a small oil refinery or medium-sized petrochemicals plant. However, closer inspection reveals that it is a corn-processing plant a biorefinery producing, inter alia, high-fruc-tose corn syrup, ethanol and lactic acid. As James R. Stoppert, a senior executive of Cargill pointed out, the chemical industry is based on carbon and it does not matter if the carbon was fixed 2 million years ago or 6 months ago [1]. 

Products. The valence tautomerization reaction (18), which gives rise to bicyclo [3.2.0] hepta-2,6-diene, was first reported by Dauben and Cargill. The reaction has a quantum yield of 0.01 or less in the vapor phase and is a minor mode of isomerization. In the condensed phase, this reaction accounts for much of the 1,3,5-cycloheptatriene that is photolyzed although the quantum yield is of the same order (0.03). A second isomerization process gives rise to toluene. The quantum yield... 

Cargill, Inc. contracted for and processed about 10001 of safflower seed in the U.S. northern Great Plains during 1947 and 1948 the company concluded that the crop was not sound at that time (34). Two men and one company provided the real imperns for getting safflower established as a crop in the United States Claassen, Knowles, and the Pacific Vegetable Oil Corp. (PVO). 

Polylactic acid is a biodegradable polymer. It can be made from lactic acid, which can be produced by fermentation of glucose. Because it is biodegradable and can be manufactured from agricultural products, polylactic acid is potentially a renewable material. US 6,326,458 assigned to Cargill Inc. describes a process for making polylactic acid from lactic acid. Estimate the cost of production of the purified polymer.
