Glossary

ASTM Certified

 

ASTM International is an international standards organization that develops and publishes voluntary consensus technical standards for a wide range of materials, products, systems, and services.


Biodegradable

 

Capable of being broken down especially into innocuous products by the action of living things (as microorganisms)


Bisphenol A (BPA)

 

BPA is an industrial chemical that has been used to make certain plastics and resins since the 1960s. BPA is found in polycarbonate plastics and epoxy resins. Polycarbonate plastics are often used in containers that store food and beverages, such as water bottles.


Compost

 

A decayed mixture of plants (such as leaves and grass) that is used to improve the soil in a garden.


Corn Starch

 

Starch made from corn and used in foods as a thickening agent, in making corn syrup and sugars, and in the manufacture of adhesives and sizes for paper and textiles


Expanded Polystyrene (EPS)

 

Expanded polystyrene (EPS) is a rigid and tough, closed-cell foam. It is usually white and made or pre-expanded polystyrene beads. EPS is used for many applications e.g. trays, plates, bowls and fish boxes.


Gluten

 

A substance in wheat and flour that holds dough together


GMO

 

Genetically modified organism.


Oriented Polystyrene (OPS)

 

OPS is produced by stretching extruded PS film, improving visibility through the material by reducing haziness and increasing stiffness. This is often used in packaging where the manufacturer would like the consumer to see the enclosed product.


Oxo-biodegradable

 

Oxo-biodegradable is made from polymers such as PE (polyethylene) PP (polypropylene) and PS (polystyrene) containing extra ingredients (NOT heavy metals) and tested according to ASTM D6954 or BS8472 or AFNOR Accord T51-808 to degrade and biodegrade in the open environment.


Polyethylene Terephalate (PET)

 

PET is the most common thermoplastic polymer resin of the polyester family and is used in fibers for clothing, containers for liquids and foods, thermoforming for manufacturing, and in combination with glass fiber for engineering resins. Bottles made of PET can be “recycled” to reuse the material out of which they are made to reduce the amount of waste going into landfills.


Polylactic Acid (PLA)

 

PLA  is a biodegradable thermoplastic aliphatic polyester derived from renewable resources, such as corn starch  (in the US and Canada), tapioca roots, chips or starch (mostly in Asia), or sugarcane (in the rest of the world).


Polypropylene (PP)

 

Polypropylene is a thermoplastic polymer used in a wide variety of applications including packaging and labeling, textiles (e.g., ropes, thermal underwear and carpets), stationery, plastic parts and reusable containers of various types, laboratory equipment, loudspeakers, automotive components, and polymer banknotes.


Polystyrene (PS)

 

A hard, stiff, brilliantly transparent synthetic resin produced by the polymerization of styrene. It is widely employed in the food-service industry as rigid trays and containers, disposable easting utensils, and foamed cups, plates, and bowls. Polystyrene is also copolymerized, or blended with other polymers, lending hardness and rigidity to a number of important plastic and rubber products.


Post-consumer

 

Material that was used and recycled for reuse in another consumer product.


Renewable Resources

 

Restored or replaced by natural processes: able to be replaced by nature.


Sustainability

 

Able to be used without being completely used up or destroyed
