Edelman Berland:
Reusable Bag Study
May 2014
Methodology
2
Audience: Consumers who have received/purchased reusable
bags in the past year
Qualification Rate: From a national sample of 3,568 individuals, 2,566
terminated due to not having acquired a reusable bag
in the past year, resulting in a 28% incidence rate.
Sample Size: 1,002 National
MOE: ± 3.1%
Methodology: Online Survey
Timing: February 28 – March 7, 2014
Key Findings
• Our calculation indicates that non-woven polypropylene (NWPP) bags used for grocery
shopping are each used approximately 15 times.
– Additionally, many of these bags are infrequently or never cleaned.
• NWPP bags are forgotten on approximately 40% of grocery trips, leading many bag owners to
use plastic bags.
– Many NWPP bags are also used for other purposes, such as transporting items or storing items at
home.
• Low density polyethylene (LDPE) bags are reused by a much smaller percentage of the
population for groceries and have a reuse frequency of approximately 3 times.
3
NWPP Re-usage
The following process was used to compute the average number of bag
reuses per year.
Corrections/Exclusions
One outlier bag usage recoded to equal total number of bags (from
65 to 6), and individuals who do not own NWPP bags were
removed.
Those who do not own any NWPP bags that they use for groceries
were excluded (n=135).
Calculate Grocery
Trips Per Week
Based on trips in the
past week. Value is
capped at 7. Those
who did not report a
grocery shopping trip
in the last week are
assigned a value of 0.5.
Calculate NWPP
Bags Used Per Trip
Based on number of
NWPP bags at last trip.
Those who did not use
a NWPP bag were
assigned a value equal
to the population
median (1).
Calculate Freq. of
NWPP Use
Number of times in the
last 10 grocery trips a
person remembered to
bring NWPP bags,
divided by 10 so as to
be expressed as a
percentage.
Calculate NWPP
Bag Replacements
Values assigned based
on the frequency of
bag replacement.
Those who “never”
replace are assigned a
value equal to the bags
received in past year.
Calculate NWPP
Reuses
Divide the number of
bags used per year by
the replacement value
to arrive at the median
number of NWPP bag
reuses per person.
5
Assuming the number of shopping trips made in the last week and the number of
NWPP bags used in that trip are both typical and can be extrapolated to a full year…
First, the average number of bag reuses per year was calculated based on
grocery trips per week, NWPP bags used per trip and the frequency with
which NWPP bags are use for grocery trips.
6
NWPPR = NWPP bag reuses
52 = Number of weeks in a year
GTRIPSPW = Average grocery trips per week
NWPPPT = NWPP bags used per grocery trip
NWPPFREQ = Frequency of bringing NWPP bags on grocery trips
Among Consumers who Received/Purchased a Reusable Bag in Past Year
(52 x GTRIPSPW x NWPPPT x NWPPFREQ)NWPPR =
The following formula was applied at the individual level in the data set
to determine the average reuse rate per respondent
This value was then adjusted to account for the number of bags a person
cycles through per year. This value (U1) was assigned as follows:

44%
24%
20%
4%
5%

Never
Once a year
A few times a year
Once a month
Once every few weeks
Once a week or more
*If respondents “never” replace their bags AND did not acquire at least one NWPP bag over the past year, they are
assigned an implied rotation rate value based on half the age (in years) of their oldest bag, based on a midpoint value.
Q27: And how often do you discard and replace your non-woven polypropylene bags that you use for groceries?

Finally, the adjusted NWPP reuses per year was calculated using the
reduction factor identified by bag replacement.

The following formula was applied at the individual level in the data set
to determine the average reuse rate per respondent
When one additional exclusion is made removing individuals who shop for
groceries at warehouse clubs (their use of NWPP bags does not offset the
use of plastic retail bags) the overall reuse rate declines slightly.

Additionally, when looking at individuals in markets where a plastic bag ban
is legislated versus those in markets where a ban is not legislated, those in
legislated markets tend to use their bags slightly more frequently.*

Approximately 16.4 million
consumers in the U.S. are walking into
grocery stores each week with bags
that have NEVER been cleaned.
That’s more than the adult population
of New York.

87% of study sample use NWPP bags for groceries
28% of these consumers NEVER clean their bags
Low Density Polyethylene Bags
One-third of consumers who purchased/received a bag in the past year got
an LDPE bag, most of whom reused that bag.
Q32: In the past 12 months, have you purchased or received one of these bags?

Those who reuse LDPE bags claim to reuse the bag for groceries more than
five times; however, to calculate the average number of reuses overall, we
assume that for each non-grocery reuse the bag is only used once.

Reusable Bag Study

  • 2. Methodology 2 Audience: Consumers who have received/purchased reusable bags in the past year Qualification Rate: From a national sample of 3,568 individuals, 2,566 terminated due to not having acquired a reusable bag in the past year, resulting in a 28% incidence rate. Sample Size: 1,002 National MOE: ± 3.1% Methodology: Online Survey Timing: February 28 – March 7, 2014
  • 3. Key Findings • Our calculation indicates that non-woven polypropylene (NWPP) bags used for grocery shopping are each used approximately 15 times. – Additionally, many of these bags are infrequently or never cleaned. • NWPP bags are forgotten on approximately 40% of grocery trips, leading many bag owners to use plastic bags. – Many NWPP bags are also used for other purposes, such as transporting items or storing items at home. • Low density polyethylene (LDPE) bags are reused by a much smaller percentage of the population for groceries and have a reuse frequency of approximately 3 times. 3
  • 5. The following process was used to compute the average number of bag reuses per year. Corrections/Exclusions One outlier bag usage recoded to equal total number of bags (from 65 to 6), and individuals who do not own NWPP bags were removed. Those who do not own any NWPP bags that they use for groceries were excluded (n=135). Calculate Grocery Trips Per Week Based on trips in the past week. Value is capped at 7. Those who did not report a grocery shopping trip in the last week are assigned a value of 0.5. Calculate NWPP Bags Used Per Trip Based on number of NWPP bags at last trip. Those who did not use a NWPP bag were assigned a value equal to the population median (1). Calculate Freq. of NWPP Use Number of times in the last 10 grocery trips a person remembered to bring NWPP bags, divided by 10 so as to be expressed as a percentage. Calculate NWPP Bag Replacements Values assigned based on the frequency of bag replacement. Those who “never” replace are assigned a value equal to the bags received in past year. Calculate NWPP Reuses Divide the number of bags used per year by the replacement value to arrive at the median number of NWPP bag reuses per person. 5 Assuming the number of shopping trips made in the last week and the number of NWPP bags used in that trip are both typical and can be extrapolated to a full year…
  • 6. First, the average number of bag reuses per year was calculated based on grocery trips per week, NWPP bags used per trip and the frequency with which NWPP bags are use for grocery trips. 6 NWPPR = NWPP bag reuses 52 = Number of weeks in a year GTRIPSPW = Average grocery trips per week NWPPPT = NWPP bags used per grocery trip NWPPFREQ = Frequency of bringing NWPP bags on grocery trips Among Consumers who Received/Purchased a Reusable Bag in Past Year (52 x GTRIPSPW x NWPPPT x NWPPFREQ)NWPPR = The following formula was applied at the individual level in the data set to determine the average reuse rate per respondent
  • 7. This value was then adjusted to account for the number of bags a person cycles through per year. This value (U1) was assigned as follows: 7 44% 24% 20% 4% 5% 4% Never Once a year A few times a year Once a month Once every few weeks Once a week or more *If respondents “never” replace their bags AND did not acquire at least one NWPP bag over the past year, they are assigned an implied rotation rate value based on half the age (in years) of their oldest bag, based on a midpoint value. Q27: And how often do you discard and replace your non-woven polypropylene bags that you use for groceries? Value Assigned 52 17 12 3 1 # of NWPP bags acquired in past year* Frequency of NWPP Bag Replacement
  • 8. Finally, the adjusted NWPP reuses per year was calculated using the reduction factor identified by bag replacement. 8 15.0 NWPP Bag Reuses Among Consumers who Received/Purchased a Reusable Bag in Past Year (52 x GTRIPSPW x NWPPPT x NWPPFREQ) NWPPR = U1 NWPPR = NWPP bag reuses 52 = Number of weeks in a year GTRIPSPW = Average grocery trips per week NWPPPT = NWPP bags used per grocery trip NWPPFREQ = Frequency of bringing NWPP bags on grocery trips U1 = Number of NWPP bags a person cycles through annually The following formula was applied at the individual level in the data set to determine the average reuse rate per respondent
  • 9. When one additional exclusion is made removing individuals who shop for groceries at warehouse clubs (their use of NWPP bags does not offset the use of plastic retail bags) the overall reuse rate declines slightly. 9 14.6 NWPP Bag Reuses Among Consumers who Received/Purchased a Reusable Bag in Past Year and Do Not Shop at Warehouse Clubs (52 x GTRIPSPW x NWPPPT x NWPPFREQ) NWPPR = U1 NWPPR = NWPP bag reuses 52 = Number of weeks in a year GTRIPSPW = Average grocery trips per week NWPPPT = NWPP bags used per grocery trip NWPPFREQ = Frequency of bringing NWPP bags on grocery trips U1 = Number of NWPP bags a person cycles through annually The following formula was applied at the individual level in the data set to determine the average reuse rate per respondent
  • 10. Additionally, when looking at individuals in markets where a plastic bag ban is legislated versus those in markets where a ban is not legislated, those in legislated markets tend to use their bags slightly more frequently.* 10 17.3 NWPP Bag Reuses Among Consumers who Received/Purchased a Reusable Bag in Past Year and Do Not Shop at Warehouse Clubs (52 x GTRIPSPW x NWPPPT x NWPPFREQ) NWPPR = U1 The following formula was applied at the individual level in the data set to determine the average reuse rate per respondent * Note that legislated market results are based on a small sample size of 65 respondents compared to 733 in non- legislated markets. Additional sample could further validate these results. Legislated Markets 13.9 NWPP Bag Reuses Non-Legislated Markets
