San Francisco International Airport 1-1 August 2013

Waste Characterization Study

SECTION 1

Background

At the request of South San Francisco Scavenger Company, ESA conducts this annual study to

characterize materials disposed from San Francisco International Airport. This report covers the

study that took place from July 16 through 22, 2013.

The methodology repeated that of previous studies (2008, 2011 and 2012) as closely as possible.

On each day, ESA staff recorded visual observations of garbage loads. Most were compactors,

but there were also several roll-off box loads (uncompacted) and one load, consisting of the

contents of several smaller containers, that was brought in by a front-end loading (FEL)

collection truck. A total of 22 sources were sampled. The results are organized in the same

manner as previous reports, for ease of comparison.

ESA appreciates the efforts of staff at South San Francisco Scavenger Company to provide the

necessary space and coordination for this study to occur.



SECTION 2

Methodology

2.1 Sample Sources

The sources were 16 compactors, five uncompacted rolloff boxes, and one load consisting of the

contents of several smaller bins, which are also known as front-end-loader (FEL) containers. All

of these sources are located around the Terminal complex as shown in Figure 2-1. The location

of each source is provided in Table 2-1 below.

2.2 Methodology

ESA observed the contents of each of the sources one time. Each load was placed on the floor of

the transfer building in a designated location where ESA staff could review the contents. Sample

areas were delineated in each load at the front, rear and middle, and were examined closely. Any

bags in the sample were opened and the contents spread out so that a visual characterization of

the material composition could be made. Taken together, the three samples from each load

contained a sufficient volume of material to be considered representative of all the material types

in the load. Through visual observation, and based upon experience with other waste

characterization studies, ESA estimated and recorded the percentage, by volume, of each material

type in the sample.



SECTION 3

Analysis of Data

3.1 Material Categories and Types

The primary materials category groups and material types (within each group) for the visual

observations were defined as follows:

Paper includes corrugated boxes, high grade paper, newspaper, magazines, mixed paper,

and multi-layer composite paper.

Plastic includes recyclable PET and HDPE containers, other plastic containers, plastic

bags and film, plastic cutlery, expanded polystyrene, mixed rigid plastics, and other

plastics. For the 2011 study, three material types were added to the Plastic group:

Compostable plastic containers, compostable bags and film, and compostable plastic

cutlery. These types continued to be used in 2012. For the 2013 study, recyclable (i.e.,

clean) plastic film was added to the Plastic group.

Glass includes glass containers such as bottles and jars, and other glass, such as plate

glass.

Metal includes aluminum cans, other non-ferrous metals, steel food and beverage cans,

other ferrous metal, and white goods (large appliances)

Plant Wastes includes leaves and grass, branches and stumps, and prunings and

trimmings.

Organics includes food scraps, other compostables, , untreated lumber, pallets, and

treated wood wastes. The previous study included diapers in this category. They are

now classified as Miscellaneous Materials.

Other Compostables includes all organic materials that are not separately listed above

(food scraps, untreated lumber, pallets, and treated wood wastes) and soiled paper (which

includes food soiled paper, paper towels from bathrooms, and paper based food

packaging or food service ware, such as plates, cups, and bowls).

Miscellaneous Materials includes textiles and leather, carpet and carpet padding, diapers

and tires. For the 2013 study, recyclable carpet padding was added to the Miscellaneous

Materials group.

C&D Waste includes crushable inerts (such as concrete, rock and asphalt, and toilets &

ceramics), gypsum board or drywall, dirt & fines, other demolition materials, and other

construction materials.



Hazardous Wastes (HW) includes paint and adhesives, vehicle fluids, universal wastes

(such as batteries and lamps), medical wastes and medicines.

Special Waste includes electronics and electrical items, multi-material composite items

and other wastes that are not identified in other material categories.

3.2 Estimated Densities of Material Types

To convert the observed volumes into estimated weights, density factors were used for each of the

waste types. For consistency, the same densities were used as in the previous studies in this

series. These densities are shown in Table 3-1 below. TABLE 3-1

3.3 Conversion of Volumes to Weights

For a visual, volumetric characterization of mixed wastes such as this study, the analyst records

the amounts of various material types as estimated percentages of the total volume. For this

study, three samples were taken from each load1, and the percentages of each waste type were

estimated for each sample. The volume percentages were then averaged for each waste type. The

end result is a list of waste types, each associated with an estimated volume percentage, and with

all percentages summing to 100% for each load.

The following method was used in the 2008 and 2011 study to estimate the weight of each waste

type within the entire load, and the same method has been applied in the current study.

First, the weight of the entire load was obtained from records at the disposal site. Next, for each

waste type, the volume-percentage of that waste type was multiplied by its density, to obtain a

weight-percentage. Each of these weight percentages was then multiplied by the total load

weight to obtain the estimated weight of each component. The data sheets in Appendix A provide

these volume estimates and weight conversions.

3.4 Recyclability of Material Types

As noted above, this study is using methods that were developed for the first such study in 2008

and that were repeated in 2011 and 2012. Repeating the procedures and assumptions provides

consistency from year to year, which is helpful in identifying trends; but this approach also has

limitations. In particular, some of the assumptions about recyclability, made in 2008, may not be

realistic in the current situation.

For example, in-flight accessories given to international travelers, such as robes, eye masks and

slippers, have been classified as textiles in this study but are not generally durable enough for re-

use, and are often composite materials (partly paper or plastic) that do not have a ready market as

recyclables.

We recommend that as this study continues in succeeding years, the assumptions about the

recyclability of materials be re-evaluated and the estimates of recyclable and compostable

quantities in each load be re-evaluated. Since all of the data reside in a single Excel file, the

recalculations will be straightforward, after the assumptions are updated.

1 In 2013 there was one exception to the three-samples-per-load procedure. For the FEL (front-end-loader) sample,

there was much less material than from the compactor and rolloff box loads. A single sample, comprising more than half of the material in the load, was used. Its volume was similar to that of one sample from any other load.



SECTION 4

Field Notes From Waste Observations

4.1 Introduction

This section describes the material composition and relevant details for each of the loads

characterized in the study. Tables showing the data taken by the analyst when conducting the

characterization can be found in Appendix A of this report. The subsections below provide

specific information about each sample. Loads are listed alphabetically by source ID. Figure 2-1

in Section 2 (above) provides a map of the Airport that shows locations for most of the sources.

4.2 Sample Descriptions

4.2.1 Compactor A2 at the International Terminal Gate A-2

Compactor A-2 consisted of 94% recoverable materials (recyclable or compostable), with 46%

recyclable and 48% compostable. This contrasts with the previous year, which had

concentrations of 24% recyclable and 73% compostable materials. With construction occurring

nearby, the 2013 sample may not be typical for this location.

Materials found in this load in 2013 included:

Recyclable beverage containers, pre-sorted and bagged, apparently from aircraft or from

sources within the terminal.

Cardboard boxes and molded-pulp inserts that appear to have been generated by terminal

maintenance work.

Neck pillows, blankets and headsets that may have been discarded from aircraft.

The five most prevalent materials were:

Rank Material Weight percent Rank in 2012 Rank in 2011

1 Other Compostables 32% 2 1

2 Food 16% 1 2

3 Mixed Paper 10% 4 n/a

4 Corrugated Cardboard 10% 6 3

5 Newspaper 6% 5 6



4.2.2 Compactor D-2 at Terminal 2

This compactor consisted of 82% compostable material, mainly soiled paper products and food

scraps. Another 17% was recyclable material. Less than one percent of the contents of this

compactor would require landfill disposal.

Materials found in this load in 2013 included:

Source separated organics, including coffee grounds, some in compostable bags (also

seen in 2012).

Large brown paper sacks of old bread (also seen in 2012).

Some front of house wastes, mostly coffee cups and other compostable food containers.

Large (#10) steel cans, and mixed-paper pasta boxes, both of which should be placed in

recycling service containers.

Compostable plastic water bottles.

Post consumer sushi containers from Wakaba or Sankaku; these are not compostable, as

they are made from polystyrene.




2 Food 34% 2 1

3 Mixed Paper 6% n/a n/a

4 Glass Containers 4% n/a 5

5 Steel Food and Beverage Cans 2% 3 8

4.2.3 Compactor D-3 at Terminal 2

This load consisted of 95% materials defined as recyclable or compostable. As in 2012, ninety

percent of these materials were compostable, including both front and back of the house

materials. Almost 5% were recyclable, and the remaining 5% would need to be landfilled.

Materials found in this load included:

Front of House (FOH) materials consisting largely of compostables (paper clamshells,

compostable cups and cutlery).

Back of House (BOH) café wastes including source separated paper towels and un-

separated coffee grounds, and recyclable bottles.

Source separated organics, some in Bio-bags.

A Styrofoam fish box was included in one sample; this also occurred in 2012.






2 Food 38% 1 2

3 Paper, Multi-material 3% 4 5

4 Mixed Paper 1% 7 4

5 High Grade Paper 1% 7 6

4.2.4 Compactor E-1 at North Terminal – Gate 73

Compactor E-1 was not sampled in 2013.

4.2.5 Compactor F-1 at Gate 81

Once again in 2013, this load was rich in food and consisted of BOH discards from food vendors

as well as FOH discards, also largely compostable. Some non-compostable items were also

present, as described below. There was a noticeable increase in recyclable non-compostables,

which suggests that janitors or restaurant workers need re-training or better access to a nearby

recyclables bin.


Source separated organics including old bread, produce trimmings, and BOH wastes from

food vendors, including Firewood Pizza and Boudin, among others.

Compostable FOH wastes: paper napkins, paper plates and cups, and pizza boxes were

among the prevalent materials found.

FOH non-compostable items, including bags of empty beverage bottles, as well as

recyclable food containers (“clamshells”, etc.) and eating utensils with the brand

Taterware, which are NOT recognized as compostable by the SF Department of the

Environment.

BOH recyclable (NOT compostable) materials including HDPE bottles and jugs, and

large #10 tin cans.


1 Food 50% 1 1



4 Steel Food & Beverage Cans 2% n/a n/a

5 Glass Containers 2% n/a 4



4.2.6 Compactor G-1 at Gate 93

Materials from this load consisted primarily of bags of discards that appeared to come from the

terminal passenger areas. The most unique aspect of this load was the wide variety of materials

present in fairly large proportions, and the small amount of food waste, compared to most other

loads sampled this year.

Noteworthy materials found in this load included:

Clean separated film, in plastic bags.

FOH bags from receptacles in the terminal, containing newspapers, magazines in several

languages, beverage containers (bottles, cans and cups) and various non-recyclables.

Discards from boarding activities: boarding passes, backing from luggage tags, etc.

Socks, pajamas, slippers, pillow covers and travel kits from various carriers.

Bags of paper hand towels, etc. from restrooms.

Discards from BOH areas in the terminal were not found.

3 Multi-material Paper 8% n/a n/a

4 Food 7% n/a n/a

5 Magazines 6% 2 5

4.2.7 Compactor G-2 at Gates 94-96

Some of the materials found in this load appeared to have originated from maintenance activity,

specifically, conveyor belt repair. Maintenance also may have generated the plastic sheeting that

was disposed in a large clear plastic bag. There was a substantial amount of food-soiled paper

products, and a relatively small amount of food scraps, consistent with this container serving

front-of-house and not serving back-of-house activities. Other materials found in this load

included:

Complimentary, branded slippers used by airline passengers.

Terminal restroom paper towels, mixed with beverage containers (apparently discarded

by passengers entering restrooms).

Small plastic drink cups and paper towels apparently from in-flight trash receptacles.

E-waste: several sets of headphones.





2 Food 12% n/a n/a

3 Multi-material Paper 10% n/a 9

4 Newspaper 10% 3 2

4 Magazines 10% n/a 8



Wrappings, labels and outdated deli items from in-terminal concessionaires. Most of this

material could have been recycled or composted.

Chipboard boxes2 and molded-pulp inserts3 for replacement light bulbs, probably

originating from maintenance activity.

Beverage bottles apparently from a bar within the terminal.



2 Food 29% 4 2


4 Newspaper 5% 2 1

5 High-Grade Paper 2% n/a 7


The materials in this load were almost entirely recoverable, with only about three percent landfill

wastes. Seventy-three percent was compostable but largely non-food.


A large amount and wide variety of beverage containers and cup lids.

Two bottom seat cushions from an aircraft.

A sizeable amount of restroom hand towels.

2 Similar to cereal-box cardboard. 3 Similar to paper egg carton material.

4 PET Bottles 4% 6 8

5 Newspaper or Mixed Paper 4% n/a 7

4.2.10 Compactor H-3 at Gate 68

This compactor is marked “Food Waste Only.” In 2012 this load consisted of 98% compostable

material; this year that was 78%, with all but 3% of the remainder being recyclable materials. In

the compostable materials there were front and back of the house wastes from food vendors.

Food and soiled paper products continued to be very prevalent in this compactor.


BOH food service consisting primarily of food but also containing recyclable HDPE and

PET bottles as well as #10 (large) steel cans.

FOH wastes containing mostly compostable paper products and some food.

Styrofoam boxes, used for shipping fish to food vendors.

At least one 5-gallon HDPE cooking oil container in a cardboard “jacket.”

A bundle of bright blue single-use rubber gloves that may have been used by security

personnel.


1 Food 50% 2 1



4 Glass Containers 3% n/a n/a

5 Other Plastic Containers 2% 5 n/a


This load was largely recoverable with 57% organics and 37% recyclable materials. There were

both front and back of the house wastes from food vendors.


Thin black dinner plates made of expanded polystyrene, origin unknown.

Empty wine bottles from a bar, and empty plastic milk jugs from a coffee vendor.

Some FOH wastes consisting mostly of compostable paper products.

A large number of receipts, in trash bags.



Also, nearly all of the material in this load had been collected in large black (opaque) plastic trash

bags.



2 Food 16% 3 3


4 Glass Containers 12% 2 2

5 HDPE Bottles 4% 4 5


This load consisted of 76% organic material and 18% recyclables, with the balance (6%) being

items made of unrecyclable plastics or mixed materials (typically, packaging made of paper and

plastics combined).


Numerous beverage containers (single-serving bottles and cans).

FOH compostables: food-soiled paper and unconsumed food, often commingled with

non-compostables such as glass bottles, straws, lids from beverage cups, etc.

Bags of paper towels from restrooms, which also included unused toilet paper.



2 Food 23% 1 2




4.2.13 Compactor IT-1 at Courtyard 4

Ninety-six percent of this load consisted of materials defined as recyclable or compostable.

Seventy-nine percent was compostable, but not food rich; and 17% was recyclable.


Rigid plastic non-compostable food service items, especially bowls.

Some food but mostly other compostable material, such as FOH bowls, coffee cups,

wood stirrers, chop sticks, etc.





2 Food 21% 8 2



5 Newspaper 2% n/a n/a


The contents of this compactor were 61% compostable and 30% recyclable. The landfill

materials consisted of passenger items (pillows, a child seat, clothing, etc.) and wastes from

security (blue nitrile gloves, and break-room discards). Although it is not reflected in the table

below, which ranks materials by weight, the volume of beverage bottles and cans made a strong

visual impression.


Beverage bottles and cans.

Restroom paper towels.

FOH post consumer wastes.



2 Food 17% 2 3

3 High-grade Paper 10% 4 1

4 Newspaper 7% n/a n/a

5 Multi-material Paper 6% 3 n/a


In contrast with prior years’ characterizations, a substantial fraction of this load (22%) was

material that is defined as neither recyclable nor compostable. Signage on the compactor

indicates “Trash Only” so this may reflect some improvement in source separation. Nevertheless,

45% was compostable, evenly divided between food scraps and other compostables. Thirty-four

percent was recyclable, and by weight, most of that was paper, including corrugated cardboard,

newspapers, and office paper. In this and several other loads from the International Terminal, it

was evident that janitors are collecting discards by placing bags from small receptacles into larger

bags, then into even larger bags prior to disposal in the compactor.




Many film-plastic bags, as noted above.

FOH compostable wastes.

Several articles of clothing, as though someone had changed clothes and discarded the

clothing they took off.

Several corrugated cardboard boxes; not many, but more than in most other loads

surveyed this year.

4 High Grade Paper 10% n/a 3

5 Mixed Paper 5% n/a 1


This load was 88% compostable and 10% recyclable material. There was a substantial amount of

food waste, and it appeared that almost all of the material in these samples came from food

service businesses within the airport.


BOH wastes from retail food vendors, contaminated with film and recycling, some using

compostable bags.

FOH wastes consisting largely of compostable materials, but with beverage containers

and non-compostable plastic utensils in the mix.

4.2.21 30-Cubic Yard Rolloff Box at North Field Maintenance Area

This load was very different from most of the others. Several large components were probably

one-time-only occurrences. Sixty percent of the load was recyclable, and another 32% was

compostable.


Soil, apparently from landscaping work, and sand from a damaged sand-barrel traffic

control device. The sand-barrel, made of hard plastic, was also in this load.

Other large plastic items: trash cart, blue barrel, milk crates, pails, etc.

Several suitcases, damaged beyond repair.

4.2.22 Front-End-Loader (FEL) Bins at Multiple Locations

This load consisted of the contents of containers collected by a front end loading truck, ranging in

size up to 6 cubic yards and located at sites shown with the symbol "[B]" in Figure 2-1. The FEL

bin contents were combined into a single load, much smaller than the other loads described

above. This was sampled by extracting a longitudinal strip from one side of the pile, comprising

about 25% to 30% of the entire load. Taking a long strip of material was done to provide a blend

of material from various collection points at the airport. Almost all of the materials were bagged,

and they were relatively clean. Ninety-six percent of the contents consisted of materials defined

as recyclable or compostable.


Restroom hand towels collected in non-compostable bags.

Aircraft-size beverage cups, and single-serving beverage bottles.

Snack bags.

4.3 Summary of Observations

Table 4-1 below lists the potential maximum recovery rate for each of the loads based on the

composition of the materials observed at the transfer station. Materials have been categorized as

recyclable, compostable, or non-recoverable (trash), following the same classification scheme as

the 2011 study.

Based on 2012 findings, a material category was added for recyclable plastic film: not soiled trash

bags but clean stretch wrap as well as packaging from retailers. This material was found in

substantial quantities within some loads, and not at all in others. Source separation, accumulating

this material in large clear plastic bags, may be a viable recycling method where it is generated.

Common recyclable materials include all corrugated boxes, high grade paper, newspaper,

magazines, and mixed paper; PET and HDPE containers, other plastic containers, mixed rigid

plastics, clean plastic film; glass food and beverage containers; aluminum cans, other non-ferrous

metals, steel food and beverage cans, other ferrous metal.

Other recyclable materials include white goods such as appliances; electronic wastes; hazardous

materials such as paint and fluorescent tubes; carpet and carpet padding; tires; crushable inerts

(such as concrete, rock and asphalt, and toilets & ceramics), gypsum board or drywall, and dirt &

fines.

Compostable materials include food; paper or fiber based food service ware, soiled paper napkins

and towels, waxed paper and cardboard; leaves and grass, branches and stumps, prunings and

trimmings; untreated lumber, sawdust, wood scraps, and pallets.

Non-recoverable materials include multi-layer composite paper; most textiles and leather goods;

soiled film plastics, other plastics; other glass; treated and composite wood; other composite

materials or items, including diapers.

Samples are listed in the same sequence as in the descriptions above. Percentages are by weight.

5.1 Waste Reduction: Immediate Opportunities

San Francisco International Airport is a hub of traveler activity with dozens of carriers, multiple

terminals and hundreds of staff across many operating companies. In comparing the results of

this waste characterization with those of 2011 and 2012, it is evident that most of the observations

and recommendations from those years continue to be worthy of consideration in 2013. They are

repeated below for reference.

More importantly, with three consecutive years of characterization, some shifts and trends are

becoming apparent in specific locations. In several compactors and rolloff boxes that are

intended for compostable organics, contaminants are increasing, and many of the contaminating

materials are recyclable. This appears to be occurring in the following containers: Gate 40, F1,

and H3. Also, the G1 container, which is designated for recyclables, went from 12%

compostables in 2012, to 53% compostables in 2013.

There were 11 locations where containers intended for trash (to landfill) have relatively little

trash, and a substantial amount of recyclables and/or compostables. Space constraints in these

locations may prevent adding containers, but the locations are: Maintenance, AirTrain, RAC, D3,

G2, G3, H4, H5, Gate 59, Courtyard 3, and the FEL bins.

Of the four containers at the International Terminal, IT-4 (compostables) was performing well in

2012 and continues to do so; IT-1 (Compostables) has improved from 60% to 79% compostable

material; IT-2 and IT-3 (Trash) contain roughly half compostables and 1/3 recyclables, with the

remainder, roughly 10 to 20 percent, unable to be reclaimed by recycling or composting.

The following are the prior observations and recommendations that remain relevant and will

result in further progress toward diverting materials from landfill.

1. Some food vendors appear to be source separating organics but others apparently are not.

The food vendor wastes are almost entirely recyclable or compostable.

2. Retail vendors produce largely paper and film plastic wastes. Working with them to

institute simple source separation and material custody practices will further reduce

material to landfill.

Implementation



3. Work with vendors and custodians to ensure that source separated recyclable and

compostable materials are a) identifiable by handlers and b) directed to the proper

collection containers.

4. Paper towels from airport restrooms are compostable. Restroom wastes were observed to

consist almost entirely of paper towel with only trace amounts of contaminants.

5. Many of the materials from plane clean outs can be recycled and composted. It appears

that some carriers are making efforts to collect recyclable/compostable materials in flight,

but these are sometimes being discarded as refuse.

6. Collecting clean film plastic for recycling would significantly decrease the amount of

material sent to landfill.

7. Increase opportunities for FOH separation. An increasingly ecologically conscious public

is becoming more willing to source separate their discards. They need to be provided the

infrastructure to do so.

8. Work with carriers and the administrative aspects of operations at SFO to increase

recycling and composting for their operations.

5.2 Waste Reduction: Best Practices

Prior reports in this series have described several waste reduction measures that could be

implemented more effectively at SFO. Based on our 2013 observations, we wish to reiterate a

few of them:

Capture materials that are already source separated such as paper towels, film plastics,

and recyclables.

Provide signage and receptacles to enable patrons of the airport to source separate their

wastes.

Give attention to all aspects of operations, including ticket counters, security checkpoints,

employee lounges, and maintenance yards. Very little of what is discarded has to go to

landfill. This idea should be reinforced for all employees, tenants and vendors.

Work with carriers to reduce the amount of materials produced in flight such as travel

kits, socks and pajamas. Also work with them and aircraft resuppliers to ensure that

recyclable materials are not sent to landfill when they are offloaded from an airplane.

Janitorial staff in the gate areas may also need to be trained in this regard.

For all of the above measures, periodic monitoring and retraining will be necessary for

these efforts to become ingrained in work practices at SFO.
