Additional Materials

The goals of municipalities for establishing and maintaining curbside programs vary throughout the country. For

various reasons such as mandates, policies, plant capabilities, customs, local markets (i.e. access to ocean

export), and other factors, additional compatible materials may be collected in addition to the above materials

for separation at material recovery facilities. The following chart offers ISRI’s current guidance, which shall be

updated from time to time as markets and conditions change, on the current pros and cons for each material for

the majority of curbside programs in the U.S. ISRI reserves the right to change any opinion below as it receives

feedback from its members and others in the industry. The opinions expressed do not necessarily apply to all

circumstances and programs, but are guidelines in today’s market. Notwithstanding the below, to be acceptable

to material recovery facilities, all such materials, if accepted in a mixed recyclable curbside recycling program,

should be subject to the same standards as the ISRI Inbound curbside material “Standards” above, in terms of

Source-separation, Handling, Moisture, Health Size Suitability, Material Market Suitability, and Quality. A

material is not recyclable unless there is a secondary non-landfill use or market for its consumption. Use of ISRI

Scrap Circular specifications is recommended as a guide.

Material

Pros

Cons

#1 - #7 mixed

plastics

Markets do form regionally, locally,

or export for mixed plastic bales.

Markets also fluctuate and can

disappear with oil/resin prices

changes.

Allows curbside programs to be

permissive.

Only stable domestics markets are for

#1, #2, and #5 plastics.

#1 - #7 mixed plastic bales are

sometimes not marketable from

some locations.

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.

Must assure brokered #1- #7 mixed

bales, especially exports, do not go

through secondary processing
