Inbound Curbside Recyclables for MRFs

manually from other thermoforms

and can contaminate bales.

Thermoform PET

food or bakery

containers

(clear top, black

bottom)

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 together

with PET bottles

In MRFs where hand-sorting occurs,

sorters cannot distinguish PP from PS

or polyethylenes

Some optical sorters cannot

distinguish black bottom thermoform

Downgrades for premium plastics

occur in some markets

Aluminum Foil

Is acceptable in some export bales

and very limited quantities in UBC.

Some programs on MRF residual

recover Al foil

Hard to generate in a clean form from

residential sources.

Many restrictive export countries will

not take foil which has been used

with food and could reject bales.

Foil disintegrates and flakes with age.

If in small pieces, foil flashes in an

aluminum furnace.

Foil can contain high moisture

food/household oil waste, which can

explode when introduced into a

furnace.

Domestic markets can be less

tolerant than export

Before accepting check with market.

Shredded Paper

<1” diameter loose

Is acceptable in some of curbside

programs

Can be captured with some later

technology MRFs through light

fraction separation and optical

sorting.

May be acceptable in Kraft bags in

some mixed paper producing

MRFs.

Does not get captured because of size

recognition limitations at some MRFs

and leaves MRFs as residue or in fines

products like glass.

Holds moisture and raises content of

moisture in paper bales and in glass.

Size of fiber strands makes it less

recyclable.
