Revision as of 08:28, 6 September 2012
Welcome to the TU Darmstadt iGEM 2012 page
Overview
The increasing contamination of our environment with plastic waste like bottles, textiles and moulded components leads to a serious risk for nature and humans. Over 150 million tons of plastics are produced per year. The majority of these plastics is the polymer polyethylene terephthalate (short PET). Most of the produced plastics is not disposed correctly, especially in the developing countries a huge amount ends up in rivers and finally in the oceans.
Ones arrived the plastic parts accumulate in ocean streams, swirl and erode or are washed back to the shores. PET is a non digestible plastic, so it stays in the environment. Under constant contact with salty seawater, UV irradiation and mechanical stress the PET is bruised into particles with a size spectra of micro and nano meters. These particles have a hydrophobic surface, where mutagenic substances and toxins can attach. These particles are taken up by fish and clamps and therefore enter into the food chain with unknown long-term effects.
At present there is no microorganism known which is able to digest synthetic plastics. In some sea territories plastic micro particles exceeds the plankton concentration. This is highly alarming especially since we do not yet know about the adverse effects of these particles.
Our mission
The declared aim of our project is to generate a genetically modified micro-organism, which will help us to decompose polyethylene terephthalate (PET, the main component of plastic bags, plastic bottles, etc..) in a way that it serves as raw material in microbial systems. Additionally this new raw material should provide a basis for further usable compounds for the chemical and pharmaceutical industry. The project is both environmental economics and industrial perspective of interest, because PET is not biodegradable and there is yet no way to recycle it completely. This leads to an increasing importance of PET waste as a component of global pollution.
More information concerning the how's and who's of this project can be found in the top section.
