PREFERRED

All plastic dispensers, pumps, and valves are considered preferred when:

  1. Made with PP, HDPE, LDPE, and/or PE copolymers including TPO’s and EVA, TPE elastomers
  2. All plastic material floats in water after granulation per APR O-S-01.

APR Design® for Recyclability Recognitions

All plastic dispensers, pumps, and valves with density > 1.0 g/cm3 that sink in water per APR O-S-01. and do NOT contain PVC materials

Materials with densities greater than 1.0 g/cm3 are expected to sink in the float-sink tank, thereby separating from the HDPE. They also do not damage or wear cutting machinery in the recycling process. Small amounts of these materials, with the exception of PVC materials, that make it through the float-sink process can be melt filtered from the recycled HDPE in the extrusion step. However, these materials are lost to the waste stream in the recycling process and are considered less preferable than an alternative floating attachment that is compatible with HDPE.

DETRIMENTAL

All plastic dispensers, pumps and valves with density > 1.0 g/cm3 that sink in water per APR O-S-01 and contain PVC materials

PVC is relatively easy to remove in the float-sink tank since it sinks while the HDPE floats. However, the float-sink tank is imperfect and even a very small amount of PVC with the recycled HDPE renders large amounts of it unusable as the PVC degrades at lower temperatures than those at which HDPE is processed.

RENDERS NON-RECYCLABLE

None specified

REQUIRES TEST RESULTS

All plastic dispensers, pumps and valves with density > 1.0 g/cm3 that float in water per APR O-S-01.

Spray dispensers, pumps or valves may be made of plastics with densities > 1.0 g/cm3 as an alternative to metals. While polymers are generally preferable to metals, the composition of a the polymers may cause it to be incompatible with HDPE recycling.

Companies that are considering such components and are unsure of their compatibility with recycling should ask their suppliers to provide APR test results

SCREENING TEST

DEFINITIVE TEST

Valves or Springs made of Metal

Sortation testing for metal components will result in either a Detrimental or a Renders Non-Recyclable ruling.

Metal contamination is highly undesirable in the HDPE reclaiming process. Metals create wear in process machinery, and increase operation costs and yield loss. While metals sink in the float/sink tank and are therefore easily separable from HDPE flakes, they contribute wear to size reduction machinery. MRFs and HDPE reclaimers use magnets, eddy current separators and metal detectors to keep packages with metal components out of the process stream. Any metal components, such as pump springs, valves, safety seals, or lidding that trigger these devices will cause the entire plastic item to be removed from the stream and not recycled.
