There are market opportunities for raw materials from sewage, but for this the
sewage treatment plants and the industry need alignment. This calls for a transition: sewage
treatment plants need to switch from treating sewage to producing valuable materials. On the
other hand, market parties need to regard sewage as a valuable source instead of ‘dirty unsafe
water’. Last but not least, the policies should better fit this new circular practice. To realize
these opportunities WOW! aims to develop value chains for three different raw materials from
sewage: cellulose, PHA bioplastics and lipids
