cessing of food & beverage products too. We are committed
to driving progress towards more sustainable manufacturing.
It is no secret that the dairy industry – which represents
around 13% of Europe's total food and drink sector – is
one of the largest users of energy and water. Dairies typically
focus on the reduction of greenhouse gases through
energy efficiency, reuse of energy and sustainable energy
generation. Generally, this is done by using efficient centrifugal
pumps in combination with highly efficient motors,
centrifuges with low pressure technology, water buffers for
heat recovery – and other plant-optimising technologies.
Separation is a key area that dairy processors can target
for emissions reductions – and an area where Tetra
Pak has spent decades innovating. For instance, our
Separator with AirTight technology – which has an inlet
at the bottom and an outlet at the top – cuts energy
use by 20 percent compared to other separator designs.
When combined with EncaptTM technology,
which lowers the atmospheric pressure around the spinning
bowl by using a low-pressure pump to reduce friction,
the energy saving is an impressive 40 percent.
eFOOD-Lab International: Are there new materials which
reduce energy consumption?
Ola Elmqvist: Tetra Pak is always looking for packaging materials
that reduce energy consumption. A particular breakthrough
in this area has been our work in development plantbased
plastics. Currently, we use plant-based plastics in our
caps, closures, film and neck of packages. In fact, we were the
first in the industry in 2011 to launch caps made from plantbased
polymers. Derived from Brazilian sugar cane ethanol,
they are functionally the same as conventional (oil-based)
plastic caps but have a significantly lower carbon footprint.
Importantly, recyclability is not impacted, as the plant-based
materials are processed together with conventional polymers
without restrictions. Since introducing them in 2011, we have
produced more than 12 billion plant-based plastic caps.
To date we have delivered more than 1 billion Tetra
Rex® Bio-based packages, the world's first beverage carton
to be manufactured entirely from plant-based materials.
Launched in October 2014, Tetra Rex® Bio-based is manufactured
solely from Forest Stewardship Council™ (FSC™) certified
and controlled sources paperboard,
together with plastics
derived from sugar cane, all traceable to their origins. We
are delighted to see the growing popularity of Tetra Rex Biobased
among customers. By using plant-based resources than
can be replenished naturally over time, offering the lowest
possible carbon footprint package to customers, we enable
a transition from fossil fuel-based materials, reducing the environmental
impact as well as improving resource efficiency.
eFOOD-Lab International: What is Tetra Paks view on a
more personalised nutrition?
Ola Elmqvist: In terms of nutrition, natural/organic is the
sweet spot that connects both health and the sustainability,
and consumption of such products is clearly seen by
consumers as a positive driver of change to address both.
Products with no additives or that are seasonal and/or minimal
processing also rate highly: examples include 100%
fruit juice, white milk, packaged water, coconut water and
plant-based drinks. Generally, there is a strong correlation
between health and sustainability for most products: consumers
already seem to think that what's good for them,
and what's good for the planet go hand in hand.
