<!--An impressive 214,364,825 tons of paper were recycled in 2013 worldwide. The most relevant step for the quality of recycled paper is the removal of ink (deinking).  Although chlorine has been widely banished from deinking, the process remains environmentally and economically challenging. In particular, the production of chemicals employed for deinking is energy intensive and the by-products are environmentally harmful. We want to tackle this issue by using enzymes instead of chemicals.

Enzymes have already been shown to efficiently deink paper. However, application of enzymes in industry requires a highly optimised procedure. For this, it would be ideal to develop a cheap and easy to use system based on continuous secretion of various enzymes, which could be then used to test their deinking efficiency.

Our approach relies on gene expression in Bacillus subtilis, as this species naturally secretes large amounts of proteins into its surrounding. Using B. Subtilis allows us to purify or even use our enzymes directly from the supernatant. We have developed a reliable expression plasmid for B. subtilis for the iGEM parts registry, which allows replication in Escherichia coli, as well as in B. subtilis. Finally, bacterial supernatants containing the expressed enzymes will be tested in the deinking process.

We aim revolutionize paper recycling by integrating all of the above aspects into one procedure that is simple enough to be applied not only in centralized recycling facilities, but also for implementation on a smaller scale. This would dramatically reduce the distance paper waste needs to be transported, thereby reducing the carbon footprint of the entire process.

Our system is the prerequisite to improve enzymatic deinking to a level where it is not only industrial feasible, but outperforms chemical deinking on this scale.-->

<h5> Styling your wiki </h5>

<p>Prior research has identified a number of enzyme classes that can efficiently replace the chemicals currently used in paper recycling. Despite their ability to facilitate the separation of ink particles from paper fibers, a process called deinking, enzymes have not been widely used industrially due to insufficient knowledge about efficiency and costly production and purification methods.</p>

Enzymatic Whitewashing - the ecological approach to paper recycling


iGEM Silver Award

Giant Jamboree Results

  • Won Silver Award
  • Nominated for Best Poster


Our project in a nutshell

Recycling of printed paper has made an indisputable contribution to conserving our environment.
However, current recycling methods consume vast amounts of energy and release toxic byproducts.

Dead Fish

Prior research has identified a number of enzyme classes that can efficiently replace the chemicals currently used in paper recycling. Despite their ability to facilitate the separation of ink particles from paper fibers, a process called deinking, enzymes have not been widely used industrially due to insufficient knowledge about efficiency and costly production and purification methods.

Fibers

In our project, we tackled these issues and took significant steps towards catalyzing research in the area and applying enzymatic paper recycling on an industrial scale. We developed a high throughput system which not only allows us to quantify deinking efficiency, but also to cheaply mass produce enzymes using a Bacillus subtilis secretion system.
