Project EuRyDice launched

Friday April 10, 2015 12:04

“Energy-efficient valorization of components from process streams” is the full title of the new EuRyDice project that will be carried out by AkzoNobel, Corbion, DOW, Hexion, ECN, KWR, and VITO within the ISPT framework.

The goal of this joint industry project is to find economically and technically feasible solutions for the recovery of salts and organic compounds from process streams in order to raise the chain’s energy efficiency by at least 25 percent and lower its energy consumption by at least 10 PJ per year in the Netherlands. 

The project also targets the practical implementation and improvement of innovative processes for treating process water streams that will generate significant energy savings in the industry, reduced CO2 emissions, and more efficient use of both raw materials and products.

The process involves the separation, extraction, and monetization of products and raw materials that are currently discarded as waste or that disrupt processes and thereby cause unacceptably high energy consumption or low quality or both. Project innovation should generate energy savings in two ways: by replacing current energy-intensive separation processes and by efficiently managing raw materials and products. The ultimate implementation of the new process technology

should also lead to additional high-quality employment, creating an estimated 750–1250 jobs in the Netherlands at end-user and supplier companies within a period of ten years.


Countless process water streams in the process industry contain a full spectrum of valuable components that are currently discarded during wastewater treatment. Many companies would like to transition to a closed-loop system with as many zero-discharge processes as possible. AkzoNobel, Corbion, DOW, and Hexion share a common problem comprised of two generic situations: salt recycling and the extraction of valuable organic components.

Recent developments in process technology make it possible to selectively separate valuable components from process water streams using less energy. The companies hope to set up sound business cases in which the technology not only performs well in terms of selective separation, but also leads to a 25 percent energy savings within six years.


The project comprises four technical work packages. First, the process water streams will be further identified. This should result in a set of conditions and streams for which sufficiently attractive business cases can be defined. Next comes a broad inventory of the technology, guided by the need to prevent phase transitions (evaporation) and ensure suitability for very complex mixtures. Examples of technologies that will be included in the evaluation phase are nanofiltration,

electrodialysis, capacitive deionization, pervaporation, forward and reverse osmosis, adsorption, ion exchange, and electroprecipitation. New combinations of these technologies will also be investigated. The selected technologies’ technical feasibility will be tested through model experiments using real process water streams. The results will be fed into a techno-economic analysis and used to further refine the business cases in order to make a definitive technology selection for both generic situations. Finally, the project will kick-start a validation project on the pilot-demonstration scale in which all stakeholders will be closely involved, and the results of the example cases will be translated to related process water streams at other companies in other markets. 


The project should identify energy- and cost-efficient technologies that can achieve a breakthrough in monetizing the components present in process water streams by substantially reducing energy consumption and costs. The selected single and hybrid technologies should be broadly applicable to both salt recycling and the extraction of valuable organic components. The feasibility evaluation will use industrial cases that serve as a model for the two generic situations and should lead to positive business cases. The technologies will be brought to a readiness level sufficient to enable a

full-scale demonstration project within three to five years if the next step is taken (note this next step is not a project deliverable).
