Driving with sweet tires
Drivers could soon be traveling on more sustainable tires. A technology is being tested to replace some of the petroleum ingredients in tires with renewable feedstocks. Annually, seven billion gallons of crude oil go into producing one billion tires worldwide.
The new tire material will use sugars derived from switchgrass, corn, corn cobs or sugar cane to produce bioisoprene. The sugar-based isoprene may be used in other rubber products, such as diapers and surgical gloves, to replace petroleum-based isoprene.

Waste fuels the skies
Plants and fat are helping fuel our aircraft. Alaska Airlines recently announced that it is using 15,000 gallons of biofuel in an 80/20 blend with ordinary jet fuel for some of its flights. The biofuel is derived from chicken fat, algae oil, used fryer grease and plants.
Biofuel can be used in planes with no modifications. Researchers say that if just three dozen U.S. commercial airports use the biofuel blend, more than half the U.S. passenger jet traffic would fly with renewable fuels.

Plants surviving the ozone
USDA scientists are breeding more ozone-tolerant crops after finding that future ground-level ozone could reduce soybean yields by 23 percent. Researchers are testing plants under conditions predicted for 2050, when ozone levels could be 50 percent higher than today’s concentrations. Researchers are finding different ozone tolerances in plants, which could help determine breeding for more ozone-tolerant varieties.

Soy scrubbing in for surgery
A soy-protein isolate could potentially be used in surgical dressings for burns, in facial masks and for reducing wound inflammations, a China study shows. Researchers studied color, transparency and heat-sealing ability of the soy-protein films.

Omega-3 to fight nerve damage
Omega-3 may help protect and regenerate nerves, according to University of London research. Studies on damaged mouse nerve cells found that omega-3 fatty acids gave cells protection and decreased cell death. Another study found that the sciatic nerves of mice recover more quickly and fully with omega-3. Studies suggest the fatty acid could have a role in treating peripheral nerve injuries.

Malaysian plant could lower blood sugar
Extracts from a Malaysian plant, the Water Apple, may help diabetics. A research team from Monash University in Malaysia found that the plant’s leaf extracts contain flavanoids that can lower or stabilize blood sugar levels. Certain flavanoids were found to be more effective than some diabetes medications.
Along with being an anti-hyperglycemic agent, these extracts could potentially help control diabetes complications and are currently under further laboratory study.

Soda bottles made from plants
Coca-Cola recently announced it will have 100 percent plant-based bottles on the market within five years. Currently, the company’s recyclable PlantBottle is made from 30 percent plant materials. The company is evaluating molasses, sugarcane and plant-residual materials for its
