[http://en.wikipedia.org/wiki/Hydrotalcite Hydrotalcite] is a [http://en.wikipedia.org/wiki/Layered_double_hydroxide layered double hydroxides] which is a natural mineral. It is used for the following:
* [http://en.wikipedia.org/wiki/Fire-retardant Fire-retardant] additive.
* Heat stabilizer.
* [http://en.wikipedia.org/wiki/Polyvinyl_chloride PVC] stabilizer.

 One such a technology is a procedure for intercalation of clays and a degradable polymer technology. Such degradable polymer technology has been put forward as a possible litter reduction strategy. IAM developed degradation enhancing additives based on nanostructured anionic clays. The idea is to accelerate the natural sunlight mediated degradation pathways of a littered plastic object, e.g. shopping bags. The technology was patented locally and licensed to Evergreen. Commercialization of this new nanotechnology route for controlled lifetime plastics is being investigated.

 A local patent by one of the researchers in the group revealed a novel synthesis method for layered double hydroxides from inexpensive run-of-the-mine raw materials.  Of late, layered double hydroxides synthesised from other run-of-the-mine and recycled raw materials have successfully been prepared by applying the technology.  These materials show a significant cost advantage compared to current commercial materials.  Work is currently being done to optimise the synthesis method and develop mew markets and applications for the materials.
