Recycling postconsumer PVC bottles: Technology and market development

The drive to recycle individual polymers in a “closed-loop”—that is, bottles-to-bottles—began in the late 1980s. Technology and market streams for high-volume packaging plastics like HDPE and PET evolved first. Smaller-volume packaging plastics have followed. This article describes technology development and the state of the market, including general economics for vinyl recycling. Recycling of PVC packaging, to say nothing of recycling of other plastics, continues to evolve and should be viewed as a work-in-progress; still, closed-loop recycling of PVC bottles is a commercial reality.

Market evolution of the soap and detergent industry within the past five years in western europe

Members of the Association Internationale de la Savonnerie et de la De’tergence (AIS) have furnished statistical information on various products showing growth in volume in total and in each of the countries. On the whole, the situation is favorable. In general, the global growth of the market of synthetic detergents is about 6% in volume per year, but it may vary greatly from one country to another. There is some doubt, however, that this growth rate will continue at a similar pace in the future. Although soaps have continued to decline in favor of detergents, we observe a certain stability of this type of product as a whole. As for detergents, they are increasing with respect to synthetic liquid products and washing powders. Such is not the case for cleaning products and auxiliary products. It is true, however, that the greater part of the market is presently taken by fabric washing and dishwashing products. In several countries, an important market for fabric softeners is developing recently; however, we do not yet have detailed statistical data concerning this market. While the greater part of synthetic detergent consumption has to do with household uses, there are at present many other applications. Products designed for indus trial uses are not in the AIS statistics and therefore are not covered in this study. Because the soap and detergent industry sells its products to the public, it pays close attention to the demands of the consumers, and we may expect it will continue to innovate and create new products. Within the framework of the AIS, we try to study market trends by presenting each year the statistical data of the preceding financial year (available from the AIS, 49 Square Marie Louise, Brussels). A retrospective study covering five years seemed to us interesting, and we venture to hope that the conclusions provided will serve to foresee the future.

Current status and future trends for disposable technology in the biopharmaceutical industry

Single use technology (SUT) is in widespread use throughout the biopharmaceutical industry where it is replacing traditional stainless steel plant particularly for the manufacture of small volume, high value products. The key drivers for SUT uptake include reduction of regulatory risk, lower capital and energy costs and increased facility flexibility. Disposable technology is now well established for cell culture, liquid handling and storage but its application to some downstream operations is proving more intractable. Single‐use chromatography resins are generally uneconomic at process scale and there are limitations on large‐scale tangential flow filtration capacities. The development of disposable sensor technology is lagging behind that of bioreactors and capacities for microbial culture are presently limited to 2000 litres. Concerns regarding compatibility of equipment from different suppliers and extractable and leachable testing are being addressed but continue to influence uptake of SUT by traditional manufacturers. Complete ‘plug and play’ disposable process trains, however, are becoming increasingly available and are being embraced by Contract Manufacturing Organisations (CMOs) with multiproduct facilities. © 2013 Society of Chemical Industry
