Material works like plastic but composts harmlessly
Cortec® research chemists
have developed a new, biodegradable and compostable material that
provides plastic-like qualities during use and provides 100% biodegradability
turning into water and carbon dioxide during commercial composting.
Named Eco Works® 70, the new material does not contain polyethylene
or starch. It is based heavily on annually-renewable, biobased
polyester from American corn.
Eco Works® 70 offers properties
superior to traditional non-biodegradable plastics without sacrificing
biodegradability or compostability. During use, products fabricated
with Eco Works® 70 have excellent resistance to moisture and
heat. Unlike some compostable products, Eco Works® 70 products
are shelf stable. Eco Works® 70 can be fabricated into a wide
variety of products from flexible sheeting for carry-out bags
and protective wrap to rigid sheeting for “plastic”
credit cards, phone cards and identification cards. Suitable for
fabrication in a variety of film thicknesses and forms, it offers
the first universal, biodegradable and biobased replacement to
LDPE, LLDPE and HDPE for films, bags, and molded “plastic”
and polyethylene products that meets or exceeds performance specifications
of traditional plastics.
Cortec’s latest advancement
in biodegradable plastic technologies offers retailers, agricultural
users, municipalities, and institutions a better “plastic”
material that is not tied entirely to the price or availability
of oil. Less costly than many products based solely on petroleum-based
raw materials, Eco Works® 70 enables significant labor savings
for processors that receive organic material from schools, restaurants
and curb-side programs. For growers and gardeners, it replaces
plastic sheeting without leaving detrimental plastic residue to
slowly choke fertile ground. It allows users to present a more
environmentally positive image.
Eco Works® 70 conforms to
domestic and international compostability standards including
ASTM D 6400-99 and DIN V 54 900 and can carry logos issued by
DIN CERTO and BPI to give users confidence in the commercial compostability
of the products after use.
