US municipalities and many other places in Europe have taken
recycling to the next level and accomplished a huge percentage of
remanufacturing and reuse of some materials. Most of these high numbers
apply to paper and cardboard (or the proper corrugated fiberboard name
often seen just as corrugates) and Plastic boxes
from the types of PET (polyethylene terephthalate) and HDPE (high
density polyethylene). In addition, metal beverage cans have also
reached a successful reuse with chances that next time someone opens a
soda can in the US, it would most likely be its sixth or seventh use
after initial manufacturing from virgin raw materials.
Not all plastics are from PET and HDPE tough. While these two
categories represent the bulk of the used plastics in households and
industry, there is still a good number of other products derived from
petroleum or bio-based materials which fall outside this category of
highly recycled percentage. This disparity is largely due to the fact
that plastics have different requirements and features and as a result
they have varying properties which are crucial in recycling processes
such as melting point for example. While this might seem trivial at
first, material recycling facilities are not always equipped to handle
such variety of recyclates which drives the price of the final recycled
resin up to levels which make it uncompetitive with other sources of raw
materials.
These facts, rather reasonably, raise the question of whether
biodegradable or oxy-based plastics are really as good as their
marketing and advertising campaigns promise. Surely, use of such
products sounds good, pro-environmental and encouraging green packaging
and eco-friendly products. The truth, however, could be buried in the
economics. Most municipal facilities are not equipped to handle these
newer types of packaging which cause them to end up in the general
stream of recyclates. This leads to contaminants in the mixture driving
overall product quality down.
One step consumers could take, to alleviate the situation and help
collection facilities, is to collect the biodegradable packaging
separately. PET bottles would normally be identified by the number 1 on
the bottom of the plastic bottle etc. If this number is for example 7 –
for other, this could designate a bio-based material which is best off
with the commingled or mixed type garbage – its properties should allow
it to degrade in a landfill.
