gresses through the entire system to be recycled? We assume that
the steel container is separated by a magnet and makes it all the
way to a company that will smelt the steel so that new products
can eventually be produced. However, that may not be a correct
assumption as we have also heard anecdotally that smaller and
slimmer aluminum aerosol cans have the ability to “fall through
the cracks” during the sorting process and end up in a landfill. If
this is indeed true, we need to know what size container is necessary
so that an aluminum aerosol container makes it through the
entire sorting process and can be recycled into new material.
The goal of this project is to better understand the waste
disposal system for aerosol products and the technical barriers to
recycling more containers. Then, with this increased understanding
from research, the HCPA, CMI and other stakeholders will
embark on an effort to get more aerosol containers recycled and
make the system more circular.
Beyond the sorting of aerosol containers, why is it that more
of the end-market processors who purchase bales of scrap metal
don’t accept aerosol containers? At this point, we are not aware
of any market acceptance issues with steel aerosol containers,
although it’s certainly something that needs to be confirmed.
On the other hand, there are several end-markets where
aluminum aerosol containers don’t meet specifications. The
aerosol industry has always prided itself on the high quality of
its aluminum containers, so why aren’t they meeting these endmarket
specifications—and does that really matter when there are
other end-markets that will readily purchase aluminum aerosol
containers that are mixed with other aluminum scrap? Ultimately,
what is the capacity of these end-markets and if we were able to
get consumers and workers to recycle every single aerosol product
that they use, is there a stable market for these containers?
There are many other things we hope to learn within the initial
phase of this project. From there, we’ll develop a roadmap to
determine what the next steps are, with the ultimate goal of having
every aerosol container processed into new material for future
products.
I encourage every person in the aerosol industry to get involved
with this project. It is of the utmost importance that
every stakeholder provides input into this and future projects.
