What’s happening? How does it happen?
Green Mills is a processing plant for second generation
biofuels that uses residual fats and oils (which
are imported on a global scale), food waste from supermarkets,
and grey water as resources. The combination
of different treatment processes provides
clean water and gas (which provides electricity,
heath and steam), and stands in direct contact and
exchange with companies Simadan, Cargill and a
juice making company via pipelines. The digestate
is transformed into fertilizers.
Why is this an interesting circular initiative for
circular ports?
It is exemplary for new technologies that allow to
process waste into new ressources, in connection
(industrial symbiosis) with different activities inside
the port area. However, where the logic is gathering
large volumes to be processed, a friction occurs as
now oils and fats are imported on a global scale. It
raises the question on what scale what materials are
collected and processed.
