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 / Meyer in Kruiningen will establish a residual heat coupling and through this they will save on energy cost and consumption. Globally speaking, this is a unique project, which is an initiative by the industrial symbiosis platform Smart Delta Resources (SDR).
Within SDR, energy intensive companies collaborate in the Delta region to exchange energy and feedstock, in this they aim to improve their competitive edge and reduce their fossil footprint. SDR helps the companies by mapping their residual flows and identifying business cases to exchange these products. SDR is facilitated by Economische Impuls Zeeland.
Globally unique project in Zeeland
Globally speaking it is a unique collaboration to use the residual heat from a potato manufacturer to dry the onions of the adjacent onion processing company, not to mention two leading international food companies collaboration successfully towards a more sustainable future. Wiskerke Onions will cover the bulk of the 1.6 million euro invest for the residual heat coupling. They have also received close to 800.000 euro in subsidy from the Province of Zeeland to realize this project.
Lamb Weston / Meijer will provide the residual heat free of charge and has received a 13.000 euro subsidy for personnel and design costs. With these subsidies the business case becomes economically viable, without a subsidy the coupling would nog be realize and the resulting energy reductions would not be achieved.
Reduction by sharing
Sharing residual heat between the international companies on the Nishoek industrial complex in Kruiningen, Zeeland, has an annual natural gas reduction potential of 500.000 mᶟ and an annual 875 ton CO₂-emission reduction. The project has the potential for expansion to include other companies in the future. The low temperature, residual heat is produced in the potato manufacturer’s baking process. Lamb Weston / Meijer cannot use the residual heat in her process, but Wiskerke Onions can use it to dry onions at a temperature of 25-30° 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 pleased with this initiative and this collaboration in Zeeland. It is a big step towards a more sustainable economy here in Zeeland. We are currently investigating if we can support more project like this one in the future from an industrial infrastructure fund we hope to establish.
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 directive ‘circular economy and energy transition’.
