Research and Development

USE OF SCRAP FOR THE DEVELOPMENT OF BIOLOGICALLY DEGRADABLE POLYMERS (PHA) FOR AGRICUTURE AND AGRAR-INDUSTRY

Description

The aim of the project is to make use of innovative systems for the micro-throughflow irrigation with biologically purified wastewater. For this two new filter systems and four trickle arms have been developed. The quality of the used water was tested on two plant varieties (tomatoes and paprika). Results: lowering of the contamination by faeces impurities by 99,9% and by pathogenic microorganisms by 100%. Thereby the quality of he test plants could be preserved.

Aim

Two biologically degradable foils were produced and tested, which are usable for different purposes. Both products were investigated in field trials for their abilities regarding air perviousness and water resistance, their fatigue life and the versatility in use. Thereby what was examined was whether they match traditional foils emanating from the petro-chemical industry and whether they are superior to the other already tested biologically degradable materials. New test series were started, which ranged from the manufacture of PHA from plants via the gene transfer of PHA synthase to the investigation of use possibilities in new areas requiring plastic foils. The currently most important aim is the testing of plastic bags for bio-waste disposal and for shopping bags.
