Researchers hope to use tree sap to create ’eco’ plastic

Researchers at the University of South Carolina are hoping to develop safer plastics out of the sap of evergreen trees.

Plastic is everywhere -- from food packaging, to children’s toys, to computer keyboards and mouses, it’s hard to imagine a world without it.

It’s estimated that 1 billion tons of plastic has been discarded since the 1950s. Research suggests it will take up to 500 years for some forms of the material to biodegrade.

While it can be recycled, most winds up in the landfill: according to the U.S. Environmental Protection Agency, only 8 percent of the total plastic waste generated in 2010 in the U.S. actually made it to the recycling plants.

Now, an assistant professor at the University of South Carolina is hoping to make this omnipresent material a little bit safer for the environment.

Chuanbing Tang is working to develop a new form of plastic derived from the sap of evergreen trees, instead of oil.

“Most plastics from non-renewable resources are generally not biodegradable,” Tang said in a statement.

“With a polymer framework derived from renewable sources, we’re able to make materials that should break down more readily in the environment.”

Tang collaborated with the Chinese Academy of Forestry to identify tree resins that could be used to make plastics.

There’s no word on when the material will be ready for commercial production, but the research can be read online in Macromolecular Rapid Communications.

Satellite images Kiev published as ‘proof’ it didn’t deploy anti-aircraft batteries around the MH17 crash site carry altered time-stamps and are from days after the MH17 tragedy, the Russian Defense Ministry has revealed. The images, which Kiev claims were taken by its satellites at the same time as those taken by Russian satellites, are neither Ukrainian nor authentic, according to Moscow’s ...

A graduate student in innovation design engineering at the UK’s Royal College of Art has created a synthetic leaf that mimics the functions of its real counterpart. "I have the first photosynthetic material that is working and breathing as a leaf does," said Julian Melchiorri. The synthetic leaf uses photosynthesis to produce oxygen, by absorbing light, water and carbon dioxide. The artificial ...
The £11 billion Government plan to put ’Smart meters’ in every British home

The UK government plans to put smart meters into British homes, and the costs of this program will naturally be passed on to reluctant customers. Critics of the plan suggest that this would make homes and the national grid vulnerable to terrorists, but as it’s been confirmed that government agents are most often involved in terror plots, it’s not the ...
