Residual Heat coupling Lamb Weston / Meijer & Wiskerke Onions

Lamb Weston Meijer in Kruiningen fabriek aardappelproducten

At 300 meters from each other, on the industrial terrain Nishoek in Kruiningen in the province of Zeeland, the main offices and production locations of two leading agro-food sector companies are housed: Lamb Weston/Meyer and Wiskerke Onions.

Lamb Weston/Meijer: search for reductions

Lamb Weston/Meijer, the number 2 in the world of potato processing, has a clear sustainability ambition for 2020. As of 2011, a 20% per ton finished product reduction in energy and emission has been realized. Lamb Weston/Meijer (LWM) sees more opportunities for the residual heat from the baking process, which cannot be reused at LWM.

Wiskerke Onions: need for heat-based energy

Wiskerke Onions, a world-wide player in the innovative onions processing and export, has a great need for heat-based energy for their intensive business process. The volume of the onions that need drying creates a great need for energy, in part due to the required temperature of 30°C. The LWM residual heat is ideal for this process. By transferring the heat from LWM to Wiskerke Onions (JWK), the heat can be used in the onion drying process, but also generates warmth for the company.

Residual heat coupling  

By transferring residual heat from LWM to JWK an annual reduction of 600.000 – 800.000mᶟ natural gas can be saved. An additional annual reduction of 800-900 ton CO₂ can be realized. To realize this LWM and JWK have signed an intention to collaborate for the design and building of a network, which makes the sharing of residual heat possible. Through this special partnership, considerable financial and social gain can be made. It is an excellent example for other industries where a residual heat coupling is potentially also a possibility .

Transition to a circular economy

There are potential results which can be gained in the Dutch (agro) industry in the area of cost and CO₂ emission reduction. This resonate in the Zeeuwse Economic agenda, and in the international climate targets for the realization of the sustainability targets in the area of CO₂-reduction. This project contributes to the total transition process towards a circular economy.

  • Annual natural gas reduction of 600.000 – 800.000mᶟ

  • Annual CO₂-reduction of over 800-900 ton

Smart Delta Resources

This business case is the result of a unique collaboration between energy & feedstock intensive companies in the Delta region: West North Brabant, Zeeland and the Flemish part of the Gent-Terneuzen Canal Zone. Together they form the Smart Delta Resources (SDR) platform.
 
Companies nor consumers produce 'waste'. The residual substance of the one is after all valuable raw material for the other. Only so can we produce sustainably, take steps towards the circular economy and gain or retain a competitive advantage in countries or regions that have relatively low-cost raw materials.
 
The affiliated companies develop business cases through the SDR platform for the exchange of energy and material flows. The professional literature refers to the industrial symbiosis. This type of cooperation aims at three goals:

  1. The exchange of waste that serves as a raw material from another company creates economically attractive business cases that strengthen the international competitiveness of the companies concerned.
  2. SDR contributes to the sustainable growth of industry and to achieving climate goals. This should include, among other things, the reduction of greenhouse gas emissions such as CO₂ and the reduction of fossil fuels.
  3. The close cooperation also offers opportunities for (yet) affiliated companies in the region and / or for companies that are looking for a location, it is attractive to settle in our cross-border Delta region.
  • Besparing van 600.000 – 800.000mᶟ aan aardgas op jaarbasis
  • CO₂-besparing van ruim 800-900 ton per jaar
