Experimental development of the biogas unit also serves CAPSO’s regional and national partners, enhancing its attractiveness and influence in the field of circular economy.

CAPSO will coordinate the progress of the demonstration workpackage “building decentralised wastewater installations for the recovery of energy from wastewater”. CAPSO will also contribute to test water and ressources recovery in its installations and to crossborder exchanges between partners on the WP strategy and technical solutions.


DuCoop is a sustainability cooperation that will invest in a decentral wastewater treatment system (“the ZAWENT technology”) and a 4th generation heating network in the new district ‘De Nieuwe Dokken’ in Ghent. ZAWENT will demonstrate a scalable design for circular recovery of energy, nutrients and water in sustainable urban districts.  Sanitary wastewater and shredded kitchen waste will be treated separately from the grey water commonly produced by i.e. showering, washing machines. Waste heat will be recovered from burning produced biogas and from the effluent wastewater with a heat pump. This heat recovery will be used for central heating and sanitary hot water demand for 400 housing units, offices and a city building. The remaining heat demand will be provided by recovering low-temperature (55-65°C) waste heat from a nearby industry. This industry will also reuse the effluent of the wastewater treatment plant as process water. To link all these technologies, DuCoop will also contribute to the development of new sustainable business models with smart energy management. This combination of innovative technologies will help cities and local communities abate challenges regarding climate change, sustainable energy production, global water stress and of depletion of natural resources.

Evides is a watercycle company. We produce drinking water, treat industrial and municipal wastewater and produce process water for industries. Our clients are active in the chemical and petrochemical, food and beverage industry in the Benelux and Germany. We are an innovative partner for the Dutch Waterboards. Together we develop sustainable solutions to treat wastewater and recover resources, for example in the Delft Blue Water project. Within this project we produced irrigation water for greenhouses from used urban water, Evides has set a goal to become climate neutral by 2025.

Within NEREUS, Evides will design, build and operate a pilot plant to recover water, energy and nutrients from municipal wastewater in Rotterdam.

HZ University

HZ University of Applied Sciences is based in Zeeland, the Netherlands. As a university of applied sciences, a great deal of practical research is conducted at HZ both by students and researchers, focusing on questions from the professional field. Any knowledge acquired from the research will result in new insights, which can lead to innovations and even new products for the work field as well as contributing to educating the next generation of water managers.

One of the research groups at HZ University of Applied Sciences; the Water Technology research group, works on research projects involving applicable technologies for sustainable water (re)use in a combined fresh/saline delta.

Research themes include:
1. Recycling of urban and industrial water;
2. Recovery of valuable content from wastewater;
3. Optimization of water treatment systems;
4. Fresh water availability for agriculture.

HZ has experience with the analysis of full scale systems for recovery of phosphate from industries with the aim of creating fertilizer and works on developing techniques for recovery of various other resources. Furthermore, HZ has much experience on reuse and recovery of water for industrial and agricultural applications in water stressed areas. 

In the NEREUS project HZ leads the Work Package investigating the technical feasibilities of available technologies and the monitoring of the technologies for their performance once they have been implemented by the pilot partners. HZ is responsible for the final reporting of the project; based on input from the pilot partners and data analysis, conclusions will be drawn and reported on the success of the technologies implemented regarding specific resource recovery goals.

Southern Water

Every day Southern Water treats and recycles 700 million litres of wastewater at our 368 treatment works after it has travelled through our 39,000 kilometres of sewers (that's six times as long as the entire UK motorway network).
Man-made technology and the power of nature are used to make wastewater safe to return to the environment.
One by-product of the process is 'bio-solids' (sewage sludge), which is turned into fertiliser and sold to farmers for use on crops. As Southern WateE already provide bio-solids to the agricultural community it is our aim to review the commercial and environmental impacts of recovering a more pure form of fertiliser in crystalline form. This supports the circular economy whilst also potentially improving the wastewater treatment and providing a more efficient service for our customers.
We recycle wastewater from almost two million homes before returning it to rivers and the sea.
