Report of the 2nd RCM on development of radiation-processed products of natural polymers for application in agriculture, healthcare, industry and environment. Working Material

Abstract

Radiation processing offers a clean and additive-free method for preparation of value-added novel materials based on renewable, non-toxic and biodegradable natural polymers and natural polymer waste. The results of research work showed that depending on the irradiation conditions, natural polysaccharides (alginate, chitin/chitosan, carrageeneans, carboxylmethylcellulose, etc.) could be either degraded or crosslinked by radiation. This paved the way for development of many successful applications; some of them commercialized, for use in agriculture, health care and environmental protection. The inputs for the formulation of this CRP and the key issues that need to be addressed were provided by the Consultant’s Meeting on “Radiation Processing of Natural Polymers for Development of Finished Products for Health Care, Agriculture and Environment” held in Kuala Lumpur, Malaysia from 26 – 30 March 2007. The main objective was defined as wide-spread promotion and general application of radiation processed natural materials, by coupling radiation technology and end-users to derive additional benefits from these value-added natural materials. The first RCM of the CRP was convened in Vienna on 21-25 April 2008. The participants presented and discussed the status of the field, the needs for further research, and various application possibilities. The work plan formulated during the meeting focused on  More>>

The first RCM of the CRP was convened in Vienna on 21-25 April 2008. The participants presented and discussed the status of the field, the needs for further research, and various application possibilities. The work plan formulated during the meeting focused on harmonization of procedures for characterization of irradiated polymers, and protocols for investigation of the functional properties of degraded natural polymer products and their field testing. A network for collaboration was also proposed. The Meeting Report was published and is available for all Member States. The second RCM of this CRP was held in Reims, France, on 12–16 October 2009. The meeting was attended by 14 participants who reported their individual research results obtained since the first RCM, as well as their further plans. This meeting report contains all these reports, as well as the reports by participants from Algeria, Japan and Thailand, who could not attend the meeting, but sent their contributions. The leaders of the harmonization exercise of the characterization procedures (Poland and UK) presented a detailed evaluation of the results and lessons learned, as well as the further plans. The report of Poland contains the summary of these findings. The detailed protocol for the determination of viscosity for chitosan solution, which was used by all participants, is given in the Annex.}
