Inbound Curbside Recyclables for MRFs

Flexible Packaging

Material over 1% of inbound flow

at some MRFs.

May be recovered for energy value

as a pellet.

May be recovered in bag-in-bag

programs.

New technologies and processes

are emerging for both sorting and

emulsifying to separate polymers.

Not acceptable as a recyclable grade

because of laminate properties and

bounded chemistry of different layers

presently. Only use is conversion.

Contaminates paper.

High food waste content.

Do not include in programs without

tackling these issues.

Mixed household

film (bagged in

bag)

A number of programs throughout

the U.S. have added this

commodity where residents stuff a

plastic bag with household film

(“bag in bag”)

Can be used as pelletized or RDF

fuel

Markets can be negative or

prohibitive to non-existent with

oil/resin fluctuations.

In most cases, cannot be exported.

Contamination can often be high.

Do not include in programs without

tackling these issues.

Mixed household

film in mixed

recyclables

(‘pick-line film’)

Required by some programs and

contracts

Can be used as pelletized or RDF

fuel

Bags can store recyclables in some

collection programs, i.e. New York

City

Markets are marginal at best and can

be non-existent for long periods.

Take back programs at grocery stores

allow full recycling.

In most cases, cannot be exported.

Contamination is inherently high.

Residents often put good recyclables

in bags causing belt to stop or loss of

recyclables to occur.

Causes major screen wrapping,

downtime and maintenance in

material recovery centers.

Contaminates paper.

Do not include in programs without

tackling these issues.

Clean, dry double-

polycoat food

packages

May be acceptable in limited

quantities in mixed paper grades

Often contains high moisture and

contaminating materials, i.e. ink,

plastic caps, straws, etc.

Some mills will reject if quantities are

too high in mixed residential grades.

Thermoform food

or bakery

containers

(delicatessen,

fresh food) clear-

i.e. ‘clamshells”

Some markets limit the amount of

#1, #2, and #5 thermoforms

allowed. Check with local markets

for limits or restrictions.

Some programs may not take them

or be able to market them with PET

bottles

Optical sorters cannot distinguish

thermoform from bottle PET, HDPE,

and PP, making QC difficult.

Downgrades for premium plastics

occur in some markets

Some thermoform polystyrene

containers cannot be distinguished
