CORN PLASTIC (PLA)
TECHNOLOGY
What are corn plastics?
Corn plastic products look and feel just like regular plastic,
but they are 100% biodegradable and compostable. Corn is
a renewable resource which makes corn plastics much more
sustainable than regular plastic. Did you know that regular
plastic is made from petroleum?
What is PLA?
PLA stands for Polylactide. PLA is made from lactic acid which
is made from cornstarch. PLA can be formed into several
different products such as cold drink cups, straws, deli
containers, sushi containers, cutleries, etc.
How long does PLA take to biodegrade or compost?
PLA is fully compostable and biodegradable. In commercial
composting conditions, PLA will compost in approximately . Composting may take longer in a home
composting bin.
What is the heat tolerance of PLA?
Normal heat tolerance of PLA is .
Remember to keep these products out of direct sunlight and
in a cool, dry place. Corn , but all other corn
plastic food containers and cups can only withstand
temperatures of 43 degrees (C).
If I throw PLA in the trash, will it biodegrade in a landfill?
PLA products react in landfills like other organic waste such
as food. PLA is fully compostable in a composting facility. In
addition, PLA is made from a renewable resource – corn –
instead of regular plastic that is made from oil.
Is PLA more or less expensive than regular plastic?
PLA is now competitively priced with regular (PET) plastic. For
some products, such as cold cups, PLA is less expensive
than PET. For other products, PLAis the same or slightly more.
What products are made out of PLA?
Products include cold drink cups, cutlery, food containers,
trash bags and more. Every day new products are being
produced and soon enough every plastic product will have a
PLA counterpart.
