abstract
In the last years, the increasing problems posed by waste
management have stimulated the interest in developing more
sustainable and bio-based solutions for the footwear industry,
including the use of biodegradable materials. As part of the
NEWALK project, the objective of this work consisted in
optimizing and implementing a respirometry system prototype.
Besides evaluating different variables, two different approaches
for measuring the evolved CO2 were assayed. Compared to
manual titration, the use of conductivity offers the advantage of
an automatic continuous monitoring.
