00:00:03
hi and welcome to this module my name is
00:00:05
logan hodgkiss i'm a member of green
00:00:07
labs austria
00:00:09
and today in collaboration with the
00:00:10
newly founded sustainable european
00:00:12
laboratories i'm going to be talking to
00:00:14
you about tackling the plastic problem
00:00:16
in the lab
00:00:18
so to give you a quick overview about
00:00:20
what we will be talking about in the
00:00:21
next few minutes
00:00:23
we'll first start our start off with an
00:00:25
introduction of why we think this is an
00:00:27
important topic to discuss
00:00:29
we'll then move into some of the
00:00:30
background research about plastic in the
00:00:32
laboratory followed by implementation of
00:00:35
recycling plastic in the lab and we'll
00:00:37
end with some concluding remarks on the
00:00:39
entire process
00:00:42
so to get started with the introduction
00:00:44
i think it's very evident in today's
00:00:46
world if you look at the different news
00:00:48
articles
00:00:49
online or in the newspapers that we have
00:00:51
a lot of environmental issues that we
00:00:53
need to address and so this can be
00:00:54
anything from the rising carbon dioxide
00:00:56
levels to the wildfires that we see
00:00:58
around the globe
00:01:00
and of course the vast amounts of
00:01:02
plastic that are being deposited not
00:01:03
only on land but also in the oceans
00:01:06
and so i think a lot of people would
00:01:07
agree that these are very pressing
00:01:09
issues but what is less intuitive is
00:01:11
what is the environmental impact of the
00:01:13
laboratories that a lot of us
00:01:14
consistently work in
00:01:16
and specifically what we want to talk
00:01:18
about today is the waste that these
00:01:19
laboratories produce
00:01:22
so to give you an idea of what we're
00:01:23
talking about here we can refer to an
00:01:25
article that came out in 2015 and this
00:01:28
article did some background research
00:01:30
into the plastic generated from a
00:01:32
specific bioscience department
00:01:34
and they found that out of 280 bench
00:01:36
scientists they produced approximately
00:01:38
267 tons of plastic in 2014
00:01:42
and this is the equivalent of about 5.7
00:01:44
million empty two-liter plastic bottles
00:01:47
now these numbers sound very very high
00:01:49
but we also have to remember that this
00:01:51
is one department in one university and
00:01:53
if we start extrapolating these values
00:01:56
to multiple departments and multiple
00:01:58
universities throughout the world we can
00:01:59
see that these numbers will add up very
00:02:01
very quickly
00:02:04
and while these numbers are kind of
00:02:05
daunting we also want to try to put this
00:02:07
into something that we can recognize a
00:02:09
bit more so within green labs austria we
00:02:11
actually did an internal study that i'll
00:02:13
talk more about later and based on the
00:02:15
study we found that the average resource
00:02:18
usage for microbiology lab per year
00:02:21
is about 13 times as high for plastic as
00:02:23
it would be for the average austrian
00:02:25
household
00:02:26
and now within this figure we also have
00:02:28
a comparative analysis for the energy
00:02:30
but what we're focusing on today is the
00:02:32
plastic
00:02:35
and so from this we think that there is
00:02:37
a problem and this is worth thinking
00:02:38
about a bit more how we can address this
00:02:40
problem and so from this point on in the
00:02:42
presentation i'm going to be talking to
00:02:44
you about how we decided to address this
00:02:47
within green labs austria and with our
00:02:49
members within austria
00:02:52
so our labs like mini labs around the
00:02:53
world go through lots of different types
00:02:55
of plastic and so of course this can be
00:02:57
anything from pipette tips eppendorf
00:03:00
tubes falcon tubes even a lot of the
00:03:02
chemicals that we order come in
00:03:03
single-use plastic containers
00:03:07
and so this is uh problematic and we
00:03:09
wanted to ask what can we do about this
00:03:11
and so we started researching
00:03:13
what we can find out about plastic and
00:03:16
what we quickly realized well hold on
00:03:18
back up for a second we wanted to ask
00:03:20
what plastic can be recycled and what
00:03:22
plastic can be replaced
00:03:24
and so now when we started looking into
00:03:26
that type of plastic we've quickly
00:03:27
realized that not all plastic is created
00:03:29
equally
00:03:30
so broadly speaking plastic is divided
00:03:32
into seven main categories
00:03:35
and these categories are primarily
00:03:37
defined about the different chemical
00:03:39
properties that pertain to these
00:03:40
different types of plastic
00:03:42
and if we look at what plastic can
00:03:44
usually be recycled it's very common
00:03:46
that we can recycle three main types
00:03:48
and so those types would include pet
00:03:51
which is what a lot of our drinking
00:03:52
water bottles are made out of
00:03:54
we have high density polyethylene and
00:03:57
also
00:03:58
polypropylene and so these are what we
00:04:00
want to look for if we are using these
00:04:02
types of plastics then theoretically
00:04:04
these are plastics that we could recycle
00:04:08
and so to address that question we
00:04:10
decided to take a look at our ordering
00:04:12
list for the year of 2019. so within
00:04:14
this list we would have all of the items
00:04:16
that our lab consumed for its regular
00:04:19
research activities
00:04:21
and so we were able to get that list and
00:04:22
try to compile and break it down into
00:04:24
the different materials that we commonly
00:04:26
go through
00:04:28
and so once we did that we found a chart
00:04:30
that looks like this and so to explain
00:04:33
this to you on the y-axis we have
00:04:36
roughly the number of items that we went
00:04:38
through in the year 2019 based off of
00:04:40
our ordering form and on the x-axis here
00:04:43
we have the different types of materials
00:04:44
so for example
00:04:46
one of the items that we ordered the
00:04:47
most was filter tips which were made of
00:04:49
polypropylene
00:04:52
and the color code here represents a
00:04:54
couple different things first of all we
00:04:55
marked green as plastic materials that
00:04:58
we order that theoretically can be
00:05:00
recycled
00:05:01
we marked items in blue such as paper
00:05:03
towels and paper tissues as items that
00:05:05
are not plastic but could still be
00:05:06
recycled
00:05:08
and finally in red we have several
00:05:10
different materials that are just a lot
00:05:12
more difficult to recycle either because
00:05:14
of cost or in the case of nitrile gloves
00:05:16
because of a nitrile component that
00:05:17
makes them very difficult to reuse
00:05:21
and so this was very eye opening for us
00:05:23
and this encouraged us to keep going
00:05:25
further
00:05:25
and to think about what would be the
00:05:27
next steps and while this is all good in
00:05:29
theory we can see this from the ordering
00:05:31
list what we really wanted to know is
00:05:33
how much do we go through in a week and
00:05:35
so we wanted to go into the lab and
00:05:37
actually do our own experiment to find
00:05:39
out
00:05:40
how much waste we produce
00:05:42
and so to do this we actually found 12
00:05:44
volunteers who collected all of their
00:05:46
waste for an entire week
00:05:48
and once we had all that waste collected
00:05:50
we then sorted through it and divided it
00:05:52
into different categories based on the
00:05:54
item
00:05:55
and so when we did that we get
00:05:58
a waste
00:05:59
group that looks something like this
00:06:02
which is very interesting to us for
00:06:04
several different reasons first of all
00:06:06
down here in the bottom we can see that
00:06:07
we go through a massive amount of gloves
00:06:11
and i think it's a good reminder that we
00:06:12
should be conscious about how many
00:06:14
gloves we actually use and while gloves
00:06:16
are a very important part of research
00:06:17
activities in a lot of cases maybe we
00:06:20
don't need to be grabbing a fresh pair
00:06:21
however in a lot of cases we do need to
00:06:24
but it's just good to think that through
00:06:26
another thing that became very obvious
00:06:28
to us was that we were using some
00:06:30
materials that were made of plastic that
00:06:32
could easily be replaced by other items
00:06:35
so one example of this would be plastic
00:06:37
plate spreaders that we use to spread
00:06:39
microbiological cultures onto auger
00:06:42
plates
00:06:43
and rather than using
00:06:45
one time use plastic plate spreaders
00:06:47
this was something that we could easily
00:06:48
replace with glass blade plate spreaders
00:06:51
that can easily be sterilized before
00:06:53
each use
00:06:56
another great example that we were going
00:06:57
through quite a lot of were plastic
00:06:59
serological pipettes
00:07:01
and again this was something that we
00:07:02
could easily easily replace with glass
00:07:04
pipettes that can be
00:07:06
washed and autoclaved each time we need
00:07:08
to use them
00:07:10
and so this is just a good reminder that
00:07:11
we're thinking about how we can deal
00:07:13
with our plastic problem in laboratories
00:07:15
it's always good to replace items
00:07:17
whenever possible
00:07:21
and while that is good we also wanted to
00:07:23
try to quantify the rest of our waste
00:07:25
and we decided to do that by separating
00:07:27
it by weight
00:07:29
and trying to determine
00:07:30
what proportion of the total waste by
00:07:32
weight
00:07:33
is made up of different materials
00:07:36
and when we do that we get a pie chart
00:07:38
that tells us a lot of interesting
00:07:40
information first of all about 10
00:07:42
percent of our waste by weight is made
00:07:45
solely of gloves
00:07:47
about 16.5 percent of that waste by
00:07:50
weight comes completely from paper
00:07:52
and uh the largest portion of our waste
00:07:54
about
00:07:56
58 or 24 kilograms comes entirely from
00:07:59
plastic
00:08:00
and of that 24 kilograms about 11
00:08:03
kilograms or 45.8 percent could be
00:08:06
recycled
00:08:08
and so again after the order list after
00:08:10
seeing this data we decided to keep
00:08:12
following this through
00:08:13
and to see if it would be worth trying
00:08:15
to recycle this plastic
00:08:17
now this data only came from one week of
00:08:19
collection and we decided in order to be
00:08:22
more producible that we wanted to repeat
00:08:24
this process and so within our own lab
00:08:26
we repeated this process for a total of
00:08:28
four times and tried to compile all of
00:08:30
that data
00:08:32
and so we get two interesting figures
00:08:34
from this
00:08:35
we'll start with the figure on the right
00:08:37
this donut chart
00:08:38
and this is again showing the amount of
00:08:41
plastic waste on average that we
00:08:42
produced in one week and the proportion
00:08:45
that can be recycled in austria
00:08:47
and this
00:08:48
verified what we saw on the previous
00:08:50
slide that we get approximately 24-26
00:08:53
kilograms of plastic waste and
00:08:55
consistently about half of that waste
00:08:56
can be recycled
00:08:57
[Music]
00:08:59
now on the left here this bar chart we
00:09:01
tried to break down some of that waste
00:09:03
and get some more information out of it
00:09:05
and so this very top purple bar here is
00:09:07
showing the total amount of waste
00:09:10
in kilograms per researcher per year
00:09:13
so what this is saying is that on
00:09:14
average one researcher in our lab
00:09:16
produces approximately 34 kilograms of
00:09:19
waste
00:09:20
now below that purple bar we try to
00:09:22
break down that waste into the various
00:09:24
types that would be included there
00:09:26
so of the total waste polypropylene
00:09:29
which is a plastic that can be recycled
00:09:31
makes approximately 10 kilograms
00:09:34
so each researcher in our group on
00:09:36
average is producing 10 kilograms of
00:09:39
plastic per year
00:09:40
and while that might not sound like a
00:09:42
lot if we try to put that into something
00:09:44
that we can imagine a little more
00:09:45
readily this would be the equivalent of
00:09:47
approximately 11 000 one milliliter
00:09:50
pipet tips
00:09:51
which i think it's very obvious that
00:09:53
that is a massive amount of pipette tips
00:09:55
and we try to go through all these
00:09:57
different categories and break that down
00:10:00
and so again this really encouraged us
00:10:02
to keep going with this process however
00:10:05
we also wanted to expand it beyond our
00:10:08
initial laboratory and so we were able
00:10:10
to collaborate with other members of
00:10:11
green labs austria who also volunteered
00:10:14
to collect all of their waste and then
00:10:15
separated it out just like we did
00:10:18
and again we weighed all of this waste
00:10:20
we tried to put some numbers on it to
00:10:22
see if we see a consistent trend across
00:10:24
these different laboratories
00:10:30
and
00:10:31
we do
00:10:33
so again to walk you through this
00:10:34
particular graph on the y-axis now we
00:10:37
have kilograms for researcher per year
00:10:39
and then on the x-axis we have it broken
00:10:41
down into the different types of
00:10:43
material so pp for polypropylene
00:10:46
nitrile and mixed waste representing
00:10:49
items that are not plastic we have ps
00:10:51
for polystyrene and p e for polyethylene
00:10:54
and each of these
00:10:56
l1 l2 and l3
00:10:59
represents a different laboratory that
00:11:00
participated in this study and each of
00:11:02
these laboratories repeated this process
00:11:04
three to four times randomly throughout
00:11:06
the year
00:11:08
if we look specifically at polypropylene
00:11:10
we can see a couple of different colors
00:11:12
here the dark blue is representing
00:11:14
commonly used
00:11:15
polypropylene materials which would be
00:11:17
pipette tips eps falcon tubes and the
00:11:20
light blue would just represent other
00:11:22
items that are made of polypropylene
00:11:25
that aren't necessarily the commonly
00:11:27
used items
00:11:29
and while this is a lot of information
00:11:30
the big takeaway that we get from
00:11:32
looking at this data is that
00:11:33
consistently across different
00:11:34
laboratories
00:11:36
one of the biggest contributors to waste
00:11:38
is polypropylene which again is a
00:11:40
plastic that can be recycled
00:11:44
and so after seeing all of this within
00:11:45
our own lab within other labs that we've
00:11:47
been working with we decided that it was
00:11:49
worth our time and effort to develop a
00:11:51
recycling pipeline that we can implement
00:11:53
within our own labs and that we could
00:11:55
supply to other people
00:11:57
in case they wanted to do the same in
00:11:59
their own labs
00:12:04
so this brings me to the third part of
00:12:05
this presentation
00:12:06
which is discussing the implementation
00:12:08
of a plastic recycling pipeline
00:12:12
so to do this we tried to break it down
00:12:14
into three broad steps for plastic
00:12:16
recycling
00:12:18
step one would be the separation of
00:12:19
plastic materials very often when you're
00:12:21
recycling plastic it's very important
00:12:23
that you can separate it in a way that
00:12:24
makes it readily recyclable
00:12:28
so in lab materials we have two broad
00:12:30
types of plastic we have most of it is
00:12:32
being made of either polyethylene or
00:12:34
polypropylene
00:12:36
so in polyethylene we have things like
00:12:37
needle caps falcon tube lids and
00:12:39
polypropylene we have the eppendorf
00:12:42
tubes pipette tips the bodies of falcon
00:12:44
tubes
00:12:45
etc
00:12:46
and you'll see from this figure that we
00:12:48
also need to separate it into autoclaved
00:12:50
and non-autoclaved plastic
00:12:52
in almost every biological laboratory if
00:12:55
any waste has been in contact with
00:12:57
biological material it will need to be
00:12:59
autoclaved which is why we need to
00:13:00
separate it out
00:13:02
now a lot of people point out that
00:13:03
autoclaving is an energy-intensive
00:13:05
process
00:13:06
and they are absolutely correct
00:13:08
however we like to remind people that
00:13:10
regardless of whether or not you are
00:13:12
recycling this plastic it will need to
00:13:14
be autoclaved and so we're not
00:13:15
recommending to add additional
00:13:17
autoclaving steps we're just suggesting
00:13:19
that the plastic be separated ahead of
00:13:21
time and then autoclaved
00:13:25
other things to consider other than
00:13:27
the autoclaving and the separation of
00:13:29
plastic
00:13:30
is that of course if any of these
00:13:32
plastic materials have been in contact
00:13:34
with hazardous biological material or
00:13:36
toxic materials it simply cannot be
00:13:38
recycled
00:13:39
and this is not something that should be
00:13:41
new for any laboratory every laboratory
00:13:44
has protocols in place on how to deal
00:13:46
with any hazardous or toxic materials
00:13:48
and so that should always take priority
00:13:50
and none of those materials should go
00:13:51
into the plastic recycling pipeline and
00:13:53
i think that's a very important point
00:13:56
to remind people
00:13:58
but in summary for the first step it's
00:14:00
important to separate the plastic and
00:14:01
autoclave it if you need to if it has
00:14:03
been in contact with live cultures
00:14:07
step two after knowing how to separate
00:14:09
the plastic would be collecting the
00:14:11
plastic
00:14:13
the important thing we like to tell
00:14:15
people is that communication is key and
00:14:17
the idea here is to make sorting as easy
00:14:19
and sensible as possible for your fellow
00:14:21
lab members
00:14:23
so for our particular group we tried to
00:14:25
come up with some informative labels
00:14:27
that would demonstrate what items need
00:14:29
to be recycled where
00:14:31
and in our case this looked something
00:14:33
like these where we have high density
00:14:35
polyethylene over here we're trying to
00:14:37
clearly show what can and what cannot go
00:14:39
into this recycling container
00:14:41
and for polypropylene we did the same
00:14:43
thing
00:14:45
now not every lab is going to use the
00:14:48
same visuals and this is does not have
00:14:50
to be a one-size-fits-all approach a
00:14:52
great example of this from another one
00:14:54
of our member labs who started this
00:14:56
process
00:14:58
is here where they took our design and
00:15:01
the basic concept of our design but they
00:15:02
redid it in order to better communicate
00:15:04
with their own lab members because they
00:15:06
found that this worked better for them
00:15:09
and so it does not matter how you
00:15:10
communicate this whether it's visually
00:15:12
or with words as long as it's clearly
00:15:14
communicated for the people that you are
00:15:16
working with
00:15:18
once you have come up with a good way to
00:15:20
communicate this we then recommend
00:15:22
putting those labels onto individual
00:15:24
smaller containers and supplying those
00:15:25
containers directly on the lab bench of
00:15:28
the people working in the lab
00:15:30
by doing this it makes it very easy for
00:15:31
researchers to recycle pipette tips
00:15:34
eppendorf tubes etc
00:15:36
as they are going about their uh day in
00:15:39
the lab
00:15:41
at another location in the lab in a
00:15:43
spare corner that you may have we then
00:15:45
suggest to put larger containers where
00:15:47
you can then take the smaller containers
00:15:49
when they're full put them into or dump
00:15:51
them empty them into the respective
00:15:53
larger containers which then already has
00:15:55
the plastic that can be sent for
00:15:56
recycling or autoclaved and then sent
00:15:59
for recycling
00:16:00
and so this is a great way that has
00:16:02
worked very well for us in order to
00:16:04
accomplish this
00:16:07
the final step and arguably the most
00:16:09
important is the recycling of the
00:16:11
plastic
00:16:13
now not all municipalities have the
00:16:15
option of recycling plastic and
00:16:16
depending on what city you live in there
00:16:18
may or may not be different options on
00:16:21
how to do this
00:16:22
but this was a very important concept
00:16:24
for us because we wanted to know that if
00:16:26
we collect our plastic is there anyone
00:16:28
who will take it and importantly we
00:16:30
wanted to know what happens to it
00:16:33
unfortunately a lot of times when
00:16:36
plastic or trash is
00:16:38
collected it's either incinerated or
00:16:40
sent to another country to be someone
00:16:42
else's problem
00:16:43
we wanted to make sure that that was not
00:16:44
happening with our plastic we wanted it
00:16:46
to be
00:16:48
recycled so unfortunately sometimes
00:16:51
that's not always straightforward so in
00:16:53
a lot of municipalities they may have
00:16:55
plastic recycling containers but if you
00:16:57
try to follow where that plastic goes
00:16:59
it's typically sent to another waste
00:17:00
company that then has many
00:17:02
subcontractors that will take that
00:17:03
plastic and if you try to follow this
00:17:05
trail it becomes often very ambiguous
00:17:09
and people either don't know what
00:17:10
happens to the plastic that they are
00:17:11
using or they simply don't want to
00:17:14
answer your questions
00:17:16
and while this is unfortunate there are
00:17:18
ways around this and uh we highly
00:17:20
recommend that you look for
00:17:22
organizations uh businesses or companies
00:17:25
within your local area that you can
00:17:27
collaborate with that would take your
00:17:28
plastic
00:17:30
so an example for us in vienna we were
00:17:32
able to team up with an organization
00:17:34
known as stopsal salmon for iron
00:17:36
gutensvek
00:17:37
which is a group that collects plastic
00:17:39
bottle caps and recycles them while
00:17:41
donating the proceeds to sick children
00:17:43
in austria
00:17:45
and we were able to contact them and ask
00:17:46
them if they would be willing to also
00:17:48
accept the plastic that we collect from
00:17:50
our laboratories
00:17:52
and they not only agreed but they also
00:17:54
put us in contact with the facility
00:17:56
where they recycle their plastic
00:17:58
and we were able to send two of our
00:17:59
members there
00:18:00
and confirm that all the plastic that we
00:18:02
recycle does get broken down into small
00:18:05
granules and then reuse to make new
00:18:07
plastic materials and this is a company
00:18:09
known as pre-zero which i believe also
00:18:11
exists at least in germany
00:18:15
and this was very important for us this
00:18:16
really closed the loop for recycling and
00:18:18
we were able to confirm
00:18:20
that everything we're doing would uh
00:18:22
lead to the recycling of plastic
00:18:26
and so this can be a challenging part
00:18:28
but
00:18:29
with a little effort i think that almost
00:18:30
any larger city within europe it should
00:18:33
be possible to find at least one
00:18:35
organization or
00:18:37
uh business that you would be able to
00:18:39
work with
00:18:42
so to give a broad overview of this
00:18:43
entire process we of course recommend
00:18:45
that you replace any unnecessary plastic
00:18:47
consumables and then you break this down
00:18:50
into three steps first identifying and
00:18:52
separating the plastic secondly
00:18:53
collecting the plastic and finally
00:18:55
making sure it gets recycled responsibly
00:19:00
so to wrap up this entire presentation
00:19:02
and give some concluding remarks i again
00:19:04
want to come back to the important point
00:19:06
that communication is key
00:19:09
if you're thinking of trying this out in
00:19:10
your laboratory what we would recommend
00:19:12
doing is working with a smaller group
00:19:14
first if you can find two or three
00:19:16
people who are willing to give this a
00:19:17
try
00:19:18
and see how it goes they will be able to
00:19:20
give some feedback on what works and
00:19:22
what doesn't and i think that's an
00:19:24
important step before trying to roll it
00:19:26
out to a much larger lab group that's
00:19:28
what we tried and it worked very well to
00:19:30
work out some of the kinks
00:19:32
and of course it's always good to be
00:19:33
adaptable if you identify any areas
00:19:36
where you can completely remove plastic
00:19:39
that's always the primary goal
00:19:43
and while this can be a very daunting
00:19:45
process we also try to give as many
00:19:47
resources as possible
00:19:49
for labs that want to start doing this
00:19:51
so on our website
00:19:52
www.greenlabsaustria.et
00:19:56
we have a resources tab at the top of
00:19:57
our page and under those resources we
00:19:59
have an entire section devoted just to
00:20:02
plastic recycling
00:20:04
so we try to supply all the information
00:20:06
that we have found as we did this
00:20:07
process
00:20:09
and importantly we also have a section
00:20:11
for frequently asked questions
00:20:14
and so these are questions that we often
00:20:15
get from our own members and we have
00:20:17
tried to compile all of those and put
00:20:19
those on the website to make it
00:20:20
available for anyone who wants to check
00:20:22
it out
00:20:29
with that
00:20:30
that is a quick overview of our plastic
00:20:32
recycling pipeline of course if you have
00:20:33
any questions at all you can always
00:20:35
email us at info greenlabsaustria.et
00:20:39
we'll do our best to answer any of your
00:20:40
questions
00:20:41
and i have to say a big thank you to all
00:20:43
of the core members of green labs
00:20:45
austria who really made this possible it
00:20:47
was a lot of work and research to bring
00:20:49
all of this together and there's no way
00:20:50
any one of us who could have done it on
00:20:53
our own
00:20:54
we'd also like to thank our
00:20:56
group leaders for being so supportive of
00:20:58
this process and allowing us to
00:21:00
implement this within our own labs
00:21:03
um of course you can always follow us on
00:21:04
twitter
00:21:05
for greenlabs austria the sales network
00:21:07
also has a twitter account now and so
00:21:10
this is a great way that we use to
00:21:12
communicate a lot of new information
00:21:13
that we get
00:21:14
so we
00:21:15
love to have you follow us and
00:21:16
communicate that way as well
00:21:20
and uh with that again thank you and uh
00:21:22
we look forward to hearing from you if
00:21:23
you have any questions
