Zero waste sustainable Food systems: Scenarios for the cities of the future
Stephane Guilbert
Montpellier SupAgro, France
Wastes at household level constitute 53% of total losses
in EU and 60% in the USA. It is clear that that people
living in towns and large cities tend to produce more waste.
Prevention of food losses and bio-waste valorization are
quite inefficiently managed. Urban bio-waste, despite their
high nutriment value, are marginally recycled and returned
to farm soil and therefore, does not contribute to closing
biogas- chemical cycles and to supporting sustainable food
production. A foresight approach was used to i) identify
high potential socio-technological innovations in food
waste prevention and valorization and ii) extract research
questions contributing to fostering and accompanying cities’
breakthrough strategies towards zero waste sustainable food
systems, specific to different urban settings worldwide. The
exploration of three “food systems scenarios” in the context
of “three urban scenarios” allows to highlight requirements
and questions for the research which were grouped into
five broad categories related to issues or types of impacts
expected: i) society, ii) industries, food cycles and systems,
iii) health and the environment (animal health, health
public, safety and nutrition, environment), iv) technological
processes, looping cycles and associated business models
and finally v) the information and communications
technologies (ICT), data processing and applied mathematics.
High potential key measures and generic questions and
perspectives for research on the link between cities and Zero
waste sustainable food systems are discussed.
