Residual heat coupling Lamb/Weston Meijer and Wiskerke Onions now in operation

Opening restwarmtekoppeling tussen Lamb/Weston Meijer en Wiskerke Onions

The residual heat coupling between Lamb Weston / Meijer and Wiskerke Onions is now officially in operation. On Monday July 2nd , 2018, Ben de Reu, delegate of the Province of Zeeland, officiated the opening. He did this together with Chayenne Wiskerke, director of Wiskerke Onions, and Erik de Been, project manager on behalf of Lamb Weston / Meijer. The project is an initiative of the Smart Delta Resources platform, of which Lamb / Weston Meijer is a member.

From now on Wiskerke Onions will produce 35 million nets of onions by way of an energy-efficient system. This means that 1 in 5 onions consumed in the Netherlands is now being dried sustainably using 100 percent residual heat from Lamb Weston / Meijer. This flows via pipes as water with a temperature of 60 degrees Celsius from the potato processor to the adjacent plot of Wiskerke Onions. Here the heat is used to produce hot air with a temperature of 30 degrees Celsius.


This collaboration between two agro-food companies generates a saving of 500,000 m3 of natural gas each year, or the energy consumption of 300 households. Moreover, this reduces CO2 emissions by about 875 tons. That is just as much as the annual CO2 intake of fifty thousand trees.

Green deal

This project slots in with the policy of the Province of Zeeland to reduce the use of fossil fuels. To this end, the Province has concluded a Green Deal with the government which provides a subsidy to make this residual heat coupling possible. Smart Delta Resources - a joint venture of eleven energy and raw material intensive companies - also contributed to this.

"The price of natural gas will only increase in the coming years, so this is also financially sustainable", says Chayenne Wiskerke.

"Wiskerke Onions wants to be the most sustainable onion supplier on the world market. We produce a considerable percentage under the Planetproof label, and save over 10 thousand transport kilometers by carrying out our logistics via Vlissingen. We now also have 1600 solar panels on our roof. That's 2600 square meters of green energy."

Lamb Weston / Meijer is equally ambitious:

"We want to maintain a leading position in sustainable development in agrofood", says Lisette Jacobs, Director of HR & Communications. "That can only be achieved through collaborations like this. Less use of water, the prevention of waste and the minimization and greening of energy use is our sustainable top 3. The system of residual heat coupling fits in perfectly with this."

Erik de Been, project manager and responsible for the valorization of residual flows at Lamb Weston / Meijer, took the initiative to start this project together with Wiskerke Onions two years ago. "At that time there was no up-to-date energy agreement and there was no question of accelerating the stopping of the extraction of Groningen gas", says De Been. "A lot has happened over the past two years, making this system of residual heat coupling more current than ever."

Laurens Meijering (Smart Delta Resources) and Ben de Reu (Province of Zeeland) emphasize the involvement of companies:

"It is the companies themselves that are the drivers", says Meijering. "There is a lot of talk about CO2 reduction, but Lamb Weston / Meijer and Wiskerke Onions are working on it too!" De Reu: "I hope this is a good example for other companies - especially in SMEs - to also work on sustainable cooperation. "

About Provincie Zeeland and Smart Delta Resources

The project slots in with the policy of the Province of Zeeland, which is formulated in the 2017-2021 Economic Agenda. It fits in with the current social issues of a circular economy and energy transition. The project is an initiative of the Smart Delta Resources (SDR) platform, facilitated by the development company Impuls Zeeland, in which energy-intensive companies in the Delta region work together to exchange energy and raw materials to improve their competitive position. SDR makes the materials and energy flows of companies visible and develops business cases for the exchange of energy and material flows.
