The partners within the WOW! team excecuted a market potential study. The objective is to identify viable value chains for 5 carbon based products (CBE) from sewage water: PHA-bioplastic, biodiesel, bio-oil, biochar, and acetic acid. In Figure 1-1 a simplified scheme of the recovery of the 5 CBEs is shown. The full report is finished and can be downloaded! Read More
Partners within the WOW! team wrote a report that describes critical success factors for the recovery of raw materials from sewage and bringing these resources to the market based on lessons learned in EU subsidy projects. Why have some recovery techniques been successfully implemented while others are still in the pilot phase or did not succeed? Information was gathered via literature, an online questionnaire and interviews. Read More
At the beginning of 2021, the first pyrolysis plant in the Netherlands will be opened in Ede, which orders usable raw materials from sewage water. Namely the cellulose pilot of the WOW! project. In the installation that Pulsed Heat has built together with Waterschap Vallei en Veluwe and Cirtec, the cellulose in sewage water is upgraded to oil, acid fraction, gas and coal. Pulsed Heat is responsible for upgrading the residual flows, they are happy to tell you more about their role in the WOW! project. Read More
The decision support tool (DST) developed as part of the Interreg WOW! project by Avans Hogeschool (NL) has been tested by Severn Trent Water (UK). This tool has been designed to provide water industry employees with an easy to use screening tool to assess the viability of carbon-based material recovery options (PHA, lipids and cellulose) at sewage treatment plants. The first testing period got us some nice results! Read More
On the 6th of November Coos Wessels from CirTec, partner in the WOW! project, presented the WOW! project to the North Sea Commission (NSC). The NSC is one of the six geographical commissions of the Conference of Peripheral Maritime Regions (CPMR) and a cooperation platform for regions around the North Sea. Their mission is to strengthen partnerships between regional authorities which face the challenges and opportunities presented by the North Sea. In line with the NSC work on protection of the sea from marine litter and harmful substances, the Annual Business Meeting on 6 November 2020 adopted a resolution on circular economy and the reuse of resources from sewage.

In the upcoming month, the lipid-team from the WOW! project will launch the pilot installation at the wastewater treatment plant in Audun-le-Tiche (France). Carefully determined key parameters in the lab-scale experiment will now be tested on site. Read More
Sewage contains about 25-30% of the particulate fraction in the form of cellulose fibers. The source of these fibers is mainly toilet paper due to its increased consumption. Utilizing these valuable materials could reduce the use of natural resources and subsequent carbon dioxide (CO2) emissions and hence, realizing a circular economy. In the WOW project, a techno-economic assessment of the use of these cellulose fibers for bio-based products is performed at a pilot scale. Read More
Sewage water and sludge are raw materials for the production of PHA: biodegradable biopolymers made by bacteria. These polyhydroxyalkanoates can offer an interesting alternative to fossil plastics. The number of research projects in this field is therefore increasing. Reason for the Biobased Economy Lecturers Platform to organize the webinar "Recent results in PHA development" at the end of November. Read More
Last week the WOW! webinar took place during the Aquarama Trade fair 2020. Three of the project partners from the WOW! project presented the results so far. Read More
Sewage and industrial wastewater often contain many valuable substances that can be used as raw materials for biobased products. However, this potential is currently not or hardly used, resulting in loss of valuable materials. The INTERREG NWE project WOW! looks into the possibilities to create sustainable value chains from sewage water using these valuable substances. One of the value chains under investigation is the production of PHA (polyhydroxyalkanoates), a fully biodegradable bioplastic. Read More
