The document discusses matching resource flows for competitive food production in cities. It notes that vegetables are often grown using finite fossil resources for heat, carbon dioxide, and nutrients. However, these resource flows from societal activities are mainly considered a problem. The session will feature presentations on innovative approaches being used in the Netherlands to develop greenhouse food production based on available resources not currently used. Speakers will discuss using waste heat and carbon dioxide from industrial processes to greatly reduce the carbon footprint of greenhouse tomatoes.

2. E. How to match resource flows for competitive food production in cities?
- Mats Eklund, Linköpings Universitet
Food consumption in cities depends on food production that is not always sustainable.
Vegetables are often grown using finite, fossil, resources. Some important inputs for
growing vegetables in greenhouses are heat, carbon dioxide and nutrients. They are
all generated by societal activities and mainly considered as a problem. How can
these resource flows be matched? In this session you will hear about innovative
approaches to the development of food production in greenhouses in the Netherlands.
There will also be presentations about ground-breaking initiatives aiming at
developing greenhouse industry based on available resources that are not used
today.
