Overview
The increasing environmental pollution with plastic waste, like bottles, textiles, and injection-molded components, has created a serious risk for nature and humans. Currently over 150 million tons of plastics are produced per year, the major share being polymer [http://en.wikipedia.org/wiki/Polyethylene_terephthalate polyethylene terephthalate] ([http://en.wikipedia.org/wiki/Polyethylene_terephthalate PET]). With annual global production exceeding 100 million tons in 2010, [http://en.wikipedia.org/wiki/Polyethylene_terephthalate PET] on its own has created a serious waste issue. While in Western countries less than 70% of [http://en.wikipedia.org/wiki/Polyethylene_terephthalate PET] production are recovered through conventional recycling, a huge amount of [http://en.wikipedia.org/wiki/Polyethylene_terephthalate PET] in developing countries is disposed of as unprocessed waste in the environment. This often makes it into rivers and thus finally ends up in the world’s oceans.
Recently it was discovered that erosion of [http://en.wikipedia.org/wiki/Polyethylene_terephthalate PET] in a maritime environment ultimately leads to the creation of nanoparticles with undesired characteristics, as these particles tend to accumulate toxic substances on their surface. There are already some areas in the world’s oceans where measurements have found the concentration of plastic micro-particles to be higher than those of plankton. This is highly alarming, especially since the adverse long-term effects of these particles are yet unknown.
In view of this growing environmental threat and serious health risk, developing new methods for [http://en.wikipedia.org/wiki/Polyethylene_terephthalate PET] degradation has become an urgent issue. So far, biological processes play no role in recycling, as its chemical properties make PET inert to biological degradation. At present there is no microorganism known which is able to digest synthetic plastics.
Our team from TU Darmstadt designed a bacterial recycling system employing [http://ecoliwiki.net/colipedia/index.php/Escherichia_coli E. coli] that uses PET waste as a resource for synthesis of new chemical compounds. The proposed solution pursues PET decomposition into its monomers, transportation into [http://ecoliwiki.net/colipedia/index.php/Escherichia_coli E. coli] and leading via terephthalic acid (TPA) to a high-value end product (e.g catechol or amino acids). The latter’s specification is determined by the inserted enzymes to build new metabolic pathways.
Our mission
The declared goal of our project is to generate a genetically modified micro-organism, which will decompose PET (Polyethylene terephthalate, the main component of plastic bags, plastic bottles etc.) into useful monomers. So far, PET is deemed non-biodegradable and there is yet no known way to recycle it completely. The respective process has to be designed in such a way that the outputs produced can subsequently serve as useful raw material input for other microbial systems. Preferably, these materials should become an economically attractive basis for further useful compounds applicable in the chemical and pharmaceutical industry.

03/05 First media response
We've got our fist media response. Our project was published in [http://www.laborundmore.de labor&more] (in German) a monthly laboratory journal. Want to take a look inside? Feel free to [http://www.igem.tu-darmstadt.de/media/igem/material/laboremore.pdf read] (in German).
03/31 iGEM 2012 registration closes
Now it's official! The [http://www.tu-darmstadt.de/index.en.jsp TU Darmstadt] participates in the [http://en.wikipedia.org/wiki/International_Genetically_Engineered_Machine iGEM] competition for the very first time. Together with 11 teams from Germany and a total of 193 teams that registered for 2012.
04/20 We've got ourselves a logo
Inessa Popova did an amazing job creating a plushy mascot based on our scrawly sketches and PET.er is its name.
04/26 First Sponsor(s)
Our iGEM Team was able to gain its first sponsor. We persuaded the people of BRAIN, a local (Zwingenberg) biotechnology company to supply us with lab equipment and consumables. For more information take a look at our sponsors section.
05/02 Laboratory work in progress
The first iGEM lab of the [http://www.tu-darmstadt.de/ TU Darmstadt] is ready to go. We would like to thank Prof. Simon, Prof. Warzecha and Tamara Hess who gave us advise on the material requirements for the targeted experiments and provided us with the necessary working space. A second lab, a 7th floor space with a breathtaking view on the city of Darmstadt and skyline of Frankfurt, will be available soon.
05/03 BioBricks
The [http://partsregistry.org/Help:An_Introduction_to_BioBricks BioBricks] arrived and we're already running out of pipette tips, We are excitedly anticipating the first colonies to grow.
05/08 Donation of Eppendorf AG
With great joy and pleasure we received a generous donation of the Eppendorf AG, presented to us by Dr. Cora Burmeister. Now that we're high on tips we can go right back at work.
06/15 Project description online
We've got it on black and white. Our team is developing a microbial recycling system called PET.er that is able to degradate and use PET for its metabolism.
