Inbound Curbside Recyclables for MRFs

practices, or causes any

environmental damage (i.e. open

burning of residuals).

Yield from these bales may be limited

after all costs of shipping and sorting

are applied to #’s #1, #2, and #5

plastics.

#3 - #7 Plastics

Markets do form regionally, locally,

or export for mixed plastic bales.

Allows curbside programs to be

permissive.

Most volatile material baled in a

MRF. While this grade is often sold

as bales for secondary processing,

usual materials recovered are #1, #2,

and #5 plastics not recovered at the

MRF. Some polystyrene resins are

also being recovered.

#3- #7 mixed plastic bales are not

often marketable in down markets.

Generally, bales are made from all

plastic materials entering the MRF,

not just bottles (i.e., plastic

tableware, straws, etc.) which may

make them more difficult to sort for

re-use, especially after baling.

Sellers must assure brokered #3- #7

mixed bales, especially exports, do

not go through secondary processing

utilizing child or unfair labor practices

or causes any environmental damage

(i.e. open burning of residuals).

Yield from these bales may be very

limited after all costs of sorting and

shipping are applied.

Generally, bales are made after the

separation of #1, #2, and #5 bottles

from all plastic materials entering the

MRF, not just remaining bottles (i.e.,

plastic tableware, straws, etc.) which

may make them more difficult to sort

for re-use.

#6 Polystyrene and

Expanded

Polystyrene (PS)

Some states and local govt.’s target

this material.

New extruding technologies and

processes, like air-classification to

optical sorter, to PS extruder may

offer better recovery than in the

past at MRFs.

Outside of rare pilot program

instances, markets are scarce to non-

existent for MRF-derived #6;

The lightweight properties of EPS

take long period of storage time to

get to truckload quantities

Test programs have high degree of

failure so far.
