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. [less ▲]

By adopting a Circular Economy Package in 2015, European Commission aimed at stimulating transition towards a stronger and more circular economy where waste (including sewage) is no longer recognized as waste, but as a valuable resource of raw materials. This review study assesses the existing methodologies to produce biodiesel from wastewater-derived lipids. Depending on the stage of wastewater treatment where biodiesel would be extracted, it may cover up to 20% of the current European biodiesel demand. Further studies in regards to the biodiesel quality, legislative conditions and techno-economic assessment towards respective transition are needed. [less ▲]
