process of new bottles. The technology used for the
purification of post-consumer PET was created by
the company United Resource Recovery Corporation
(URRC), from United States. The use of post-consumer
PET encourages the entire chain of collection of these
packages, generating income for the street collectors
(COCA-COLA INSTITUTE, 2012).

In order to facilitate transportation and the recycling
of post-consumer packaging, some innovations that allow
a volume reduction in these stages can be found in recent
years, as shown in FIGURE 7.19. One example is the PET
bottle for water Crystal from Coca-Cola brand with the
possibility of reducing the volume by 37% volume reduction
by twisting after use
,
and it is also being produced with 20%
less PET and a percentage of PET coming from renewable
source (QUARTIM, 2011). Another example of NNew Can
metallic packaging design, developed by Jiwoon Park and
Kwenyoung Choi, has a format that allows to reduce the
volume by one-third of the original after consumption of the
product by means of twisting and compression movements
(YANKO DESIGN, 2009).

The Taiwanese company Panorama SOY Ink Co.
Ltd. has developed inks based on recycled vegetable
oils. The inks contain 45% of post-consumer oil, 21%
of pigments and 34% of tar, do not contain organic
volatile compounds, have good resistance to abrasion,
high
gloss
and good color stability. They dry faster, have
sharp point higher than traditional paints and can be
applied on surfaces of paper or plastic (DENT, 2011).
Another important concept is the
Design for
Recyclability
, which is to rethink the package, designing
it to make its recycling easily performed in commercially
