Stanford scientists make renewable plastic
from carbon dioxide and plants
STANFORD UNIVERSITY

STUDENT AANINDEETA BANERJEE AND ASSISTANT
PROFESSOR MATTHEW KANAN HAVE DEVELOPED A
NOVEL WAY TO MAKE RENEWABLE PLASTIC FROM
CARBON DIOXIDE AND ORDINARY PLANTS
...
Researchers say the new technology could
provide a low-carbon alternative to plastic bottles and other items currently made from petroleum
...
"If you could do that without using a lot of nonrenewable energy, you could dramatically lower the carbon footprint of the plastics industry

Worldwide, about 50 million tons of PET are produced each year for items such as
fabrics, electronics, recyclable beverage containers and personal-care products
...
Manufacturing PET produces significant amounts of CO2, a

greenhouse gas that contributes to global warming
...
6
For the Nature study, he and his co-workers focused on a promising alternative to PET called
7
polyethylene furandicarboxylate (PEF)
...
"PEF is an attractive replacement for PET, because FDCA can be sourced from biomass instead of
8 petroleum," Kanan said
...
"
9
Despite the many desirable attributes of PEF, the plastics industry has yet to find a low-cost way to
manufacture it at scale
...
One approach is to convert fructose from corn syrup into FDCA
...
But growing crops for
industry requires lots of land, energy, fertilizer and water
...
"It would be much better to make
FDCA from inedible biomass, like grasses or waste material left over after harvest
...
About
400,000 tons are produced annually for use in resins, solvents and other products
...
"That really defeats the purpose of what we're trying to do," Kanan said

The Stanford team's approach has the potential to significantly reduce greenhouse emissions, Kanan
