A globally unique project in Zeeland: Residual heat sharing to reduce energy consumption and emissions at Wiskerke Onions and Lamb Weston / Meijer

Wiskerke Onions and Lamb Weston/Meijer in Kruiningen, the Netherlands will realize a residual heat connection to reduce energy costs and consumption. Globally speaking, it is a unique collaborative project, which is an initiative by the industrial symbiosis platform Smart Delta Resources (SDR).


Through SDR, energy-intensive companies in the Delta region collaborate to exchange energy and materials, improving their competitive edge and reducing their dependency on the fossil industry. SDR identifies residual material and energy flows in companies and develops business cases to exchange these residual products.

Globally unique project in Zeeland

Using residual heat from a French fries producer to dry onions in the neighboring onion processing company is a unique project, just as two leading, international agro-food companies collaborating successfully in the area of sustainability.


Wiskerke Onions will cover the bulk of the 1.6 million euro investment and has been granted a subsidy of nearly 800.000 euro from the Province of Zeeland for this residual heat connection. Lamb Weston / Meijer will deliver her residual heat for free and will receive a subsidy of approximately 13.000 euro from the Province of Zeeland for the personnel and development costs. With these subsidies the business case becomes economically viable. Without these subsidies, the residual heat connection and the resulting energy reduction, would not be achieved.

Reduction by sharing

Sharing residual heat by these companies on the Nishoek industrial area in Kruiningen, Zeeland, has the potential to reduce their need for natural gas by 500.000 mᶟ per year and the potential to reduce annual CO₂ emissions by 875 ton. It is possible to extend this project to other companies in the future. The residual heat from the process in the French fries factory has a low temperature. Lamb Weston / Meijer cannot use this heat themselves, but Wiskerke Onions can dry the onions with it at a steady temperature of 25-30 degrees Celsius.

Green Deal subsidy

The Provincie of Zeeland has granted the 800.000 euro subsidy from a previous Green Deal with the Dutch government, intended to accelerate the transition to a sustainable economy. From this Green Deal the subsidies for the Sloe-warmth project in Vlissingen and the Mechanical Vapor Recompression project at Dow Benelux were granted.


Provincial executive Ben de Reu (Energy): "We are very excited for the start of this brilliant initiative and collaboration in Zeeland. It is a big step in the development of a future-proof, sustainable, economy in Zeeland. We are currently researching the possibility to help finance more projects like this in the future. For this purpose we hope to develop an industrial infrastructure fund.”

Policy in Zeeland

The residual heat connection project matches the policy the Province of Zeeland has set out in the Economic Agenda 2017-2021 and fits within their current social assignment ‘circular economy and energy transition’.
