INTRODUCTION TO THE ORGANOTIN ENVIRONMENTAL PROGRAMME (ORTEP) ASSOCIATION Click here to read the German language version of this document

International non-profit organization of producers of organotin compounds
Registered January 18, 1978
Chamber of Commerce
The Hague, The Netherlands

Aims
To promote and foster the dissemination of scientific and technical information on the environmental effects of organotin compounds and to provide greater appreciation of the available scientific and technical information on environmental aspects of organotin compounds.

History
In 1972, the International Tin Research Institute, in cooperation with global major producers of organotin compounds, set up at the Organic Chemistry Institute of the University of Utrecht in The Netherlands, an environmental research program to establish analytical methods for detecting trace amounts of organotin compounds. This work was published and enabled the first studies of mechanisms of degradation under laboratory and environmental conditions. At the conclusion of this research in 1978, companies from America, Europe, and Japan whose operations involved production of organotins founded the ORTEP Association. This organization established a database of technical and environmental information relating to organotin compounds, currently maintained in England.

Principal Objectives include:

  • To collect and disseminate all published data.
  • To collect data that may be available from member companies as unpublished and proprietary information.
  • To determine on what basis such data could be used to inform agencies throughout the world (EPA, EEC, MITI, WHO, etc.) that are studying aspects of organotin compounds.
  • To develop safety and environmental standards or procedures for safe manufacturing and use.
  • To review and develop packaging, labeling and transportation standards with the goal of achieving international uniformity.
  • To fund, co-fund and support future research efforts where specific needs are identified.

Working Groups
There is one major working group covering the use of di- and mono-alkyltin as a
stabilizer in polyvinyl chloride (PVC).
