The Gaia Project is a charitable organization whose mission is to empower youth to make informed deci-
sions about energy and its impact on the environment.
We develop projects, provide professional development, technical support and ongoing project support for
teachers and students. Our projects aim to incorporate three key principles, which symbolise our focus on
realistic environmentalism.
1. Data-Informed Decisions – We want students to be able to explain why, and quantify the effect of
each decision they made along the way to their final solution.
2. Economic Assessments – We expect students to be able to assess the cost effectiveness of their so-
lutions, and be able to optimize their projects with limited budgets.
3. Environmental Impact and Lifecycle Assessments – We need students to take a holistic view to their
projects. This means looking at their projects from cradle to grave, as opposed to just examining the
use phase, and acknowledging that greenhouse gas reduction is not the only environmental issue at
stake.

Overview
The Gaia Project and Florenceville Elementary
School collaborated on an audit of the schools’
waste on May 8th, 2014. Florenceville
Elementary School’s “Gaia Club” students,
along with Ms. Poirier and Ms. Carmichael,
have been working on firstly examining the
school’s waste and subsequently looking for
ways to reduce the school’s overall waste
footprint.
An initial audit of the school’s waste was done
on October 18th, 2012—approximately one
and a half years earlier— and this audit was a
follow-up. The process and results are detailed
within this report, including a comparison of
the results from October 2012 to May 2014.

The Process
For the current waste audit, the custodial staff
collected all of the garbage at the school on
May 6th, bagged it and placed it outside for us.
Sorting categories We decided on 6 sorting categories:
Paper & Cardboard
Recyclable plastics
Milk Cartons
Compost
Garbage
Returnable Drink Containers
The waste audit done in October 2012 included
a category for metals, which the Gaia Club
students decided to change to Milk Cartons for
this audit. The reason for this was because very
little metal was observed in the 2012 audit, and
students thought that milk cartons would be
more abundant in the garbage.
Weighing and Sorting After deciding on our 6 sorting categories, Gaia
Club students were provided with gloves,
divided into teams and provided with a kit of
supplies.
Before any bags were opened, the weight of
each bag was recorded so that the starting
amount of waste was known and could be
checked against the final amount.

Groups then opened the bags and sorted its
contents.
We subsequently weighed the contents of each
sorting category at the end of the audit. The
data from each group was entered into an excel
spreadsheet so that we could build a picture of
how much waste the school produces in a day
from each of the 6 sorting categories.
Results
The total weight of waste collected from 1
typical school day was approximately 10 kg.
The estimated total weight from one day in
October 2012 was 19 kg, representing a 9 kg or
46% reduction over the year and a half since
the initial audit. While there are many
variables that haven’t been controlled for, this
46% reduction in overall waste may indeed
represent a significant overall reduction in
waste at the school!

October 2012: 19 kg total waste
9 kg, or 46% reduction when comparing
October 2012 to May 2014
You can find the actual weight from each
sorting category (our raw data) in Table 1 in the
Appendix. The proportion of waste in each
category can be seen in the pie chart below.
As a comparison, the percentage per category
from October 2012’s waste audit is included
below (you can find the data in Table 2 of the
appendix).
Included below is a comparison graph, which
compares the amount of total waste per
category from October 2012 to May 2014 and
highlights the categories that have increased or
decreased.
Finally, the amount of waste collected and
sorted into each category has been projected
forward to provide an estimate of the waste
produced on an annual basis. Assuming 190
school days in a year, Florenceville Elementary

School produces approximately 1,900 kg of
waste annually.
Assuming 220 students that regularly attend
Florenceville Elementary School, each student
produces approximately 0.05 kg of waste per
day, and 10 kg annually.
Summary
Through the process of measuring how much
and what type of waste Florenceville
Elementary School produces, it was discovered
that on May 7th, 2014:
36% of the waste could have been
recycled. This includes paper, cardboard,
milk cartons & other drink containers,
and recyclable plastic.
34% of the waste was compostable
material.
30% of the waste was actual garbage that
needed to be there.
Paper Comparing the amount of paper in the garbage
from October 2012 (3.8 kg) to May 2014 (1.7
kg), there has been a 55% decrease in the
amount of paper put into the waste stream.
From this waste audit comparison, we can
assume that, on average, between 15-20% of
the total waste is paper.
Recyclable Plastics Comparing the amount of recyclable plastics in
the garbage from October 2012 (2.5 kg) to May
2014 (0.7), there has been a 72% decrease in
the amount of recyclable plastics put into the
waste stream.
It would be safe to conclude that approximately
5-15% of Florenceville Elementary’s waste is
recyclable plastics.
Compost Comparing the amount of paper in the garbage
from October 2012 (8.8 kg) to May 2014 (3.5),
there has been a 60% decrease in the amount
of compost put into the waste stream.
Compost represents a large share of the total
waste generated at Florenceville Elementary
(35—50%). The school’s composting program,
initiated since the last audit in October 2012,
has reduced the amount of compost being put
into the waste stream by over 60%.
Garbage There was not much of a change from the
October 2012 waste audit and the May 2014
waste audit in terms of the amount of actual

garbage produced (3.1 kg and 2.9 kg
respectively). Between 15% and 30% of the
school’s total waste is garbage, and actually
needed to go to the landfill. If the school was
to continue to reduce, recycle and compost,
there is still potential to reduce the school’s
overall annual waste from 1,900 kg to ~600 kg.
Through this audit, we observed a great
improvement from the 3,700 kg produced
annually in 2012! With further reductions, each
student would only generate 3kg of waste at
the school annually, compared to the ~10kg
produced per student per year currently, or the
17 kg produced per student annually from the
2012 audit.
Recommendations
After the waste audit was completed, the Gaia
Project along with the “Gaia Club” and Ms.
Poirier, brainstormed ideas around reducing the
amount of waste produced at Florenceville
Elementary School. These recommendations
are presented below:
Composting:
Conduct another student led
presentation to re-introduce the compost
bins and system to the rest of the school.
Place compost bins in the staffroom,
kitchen and office.
Recycling:
Place a full set of bins in each classroom
covering all categories.
Create signs with pictures detailing what
can be recycled to make it easy and fun.
Create generally bigger signs.
Paper:
Place paper recycling bins in each
classroom.
Encourage the re-use of paper by
finishing any stories you’ve started (or
saving them for later), using both sides,
using scraps to draw on, and saving
printer mistake paper.
Milk Cartons:
Designate an appropriate place where
excess chocolate milk can be disposed.
Have announcements about how milk
cartons can be re-used such as for
planting seeds, making bird feeders, or
other crafts.
General:
Place a bin in each classroom for pen/
pencil re-use.
Encourage people to bring their lunch in
re-usable containers.
Conclusion
The Gaia Project was very impressed with the
sustainability initiatives under way at
Florenceville Elementary School, especially its
highly effective composting program that has
helped reduce the amount of waste generated

daily by 46%! We consider the school to be a
model in data-informed decision making to
reduce the school’s overall environmental
footprint.
Congratulations on a job well done Florenceville
Elementary School!
Contact Us
The Gaia Project is very interested in supporting
waste reduction and other energy-related
initiatives at Florenceville Elementary School in
any that we can. The students, staff and
administration at Florenceville Elementary
School are leaders, and I look forward to seeing
what the school does next!
