DEMOCRATIZING SIMULATION
Empa, Switzerland
FORECASTING FRUIT
FRESHNESS WITH
SIMULATION APPS
Swiss research organization Empa built models and compiled a
simulation application that feeds results into a smartphone app used by
farmers and traders to predict the shelf life of fresh fruits and vegetables.
The work is in support of a multinational coalition whose goal is to
improve the use of refrigerated food storage in developing countries.
by RACHEL KEATLEY
The post-harvest journey of fresh
produce is a notably weak link in the
global food supply chain. Each year,
approximately one-third of the food
produced for human consumption
worldwide is lost or wasted. Refrigerated
distribution and storage problems play
a major role in these losses, especially in
developing countries like India, where a
mere 6% of food production enters the
refrigerated " cold chain " - leaving it
vulnerable to decay. Currently, the scarce
refrigerated space, such as small, solarpowered
cold storage rooms (Figure
1), may be occupied by crops that are
already past their peak, even as other
shipments decay while waiting for access
to a cold room.

6a COMSOL NEWS
As part of a multinational consortium
of food supply chain stakeholders, the
Swiss Federal Laboratories for Materials
Science and Technology (Empa) and the
Basel Agency for Sustainable Energy
(BASE) developed Coldtivate to help
alleviate these problems. Coldtivate is a
mobile app that informs its users of the
cooling and decay process of different
types of fruit in real time. It was rolled
out to cold storage operators in three
regions of India in late 2022 and in
Nigeria in 2023, and it is powered by
multiphysics simulation. The farmers
who use the app do not actually see
the underlying multiphysics models or
interact directly with the simulation app:
they get the results delivered in a way
that is actionable to them through the
Coldtivate mobile app.
