Enzymatic Whitewashing - the ecological approach to paper recycling
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.
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.
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 B. subtilis secretion system.
