scientists create alternative plastics using just sugars and co2  -  polycarbonate plastic
One problem with social addiction to plastic is that the main components of ubiquitous materials come from fossil fuels that are dirty, difficult, and expensive.
According to the British Plastics Federation, about 4% of global oil production is used to make plastics.
It doesn't seem to be a lot, but it's equivalent to about 3.
According to the total global oil output of 8 million barrels, 95 million barrels per day.
But scientists at the University of Bath's Center for Sustainable Chemical technology say we have a better way to make polycarbonate.
This is the type of plastic we need, from glasses, water bottles to scratches --
Coating resistance for mobile phones and dvd.
In the lab, they were able to synthesize alternative versions of polyester using only sugar and carbon dioxide at low pressure and room temperature.
Polyester made of sugar has many advantages.
In addition to not requiring oil as an ingredient, they also do not need BPA, a chemical that may have a harmful effect on the fetus and children.
It also does not need to use light gas, a highly toxic chemical used as a toxic gas in World War I.
Another benefit is that using the enzymes found in soil bacteria, these new polyester is biodegradable. "With an ever-
The population is growing and the demand for plastics is growing, "Antoine Bouchard, a researcher at the university's chemistry department, said in a press release.
This new plastic is a renewable alternative to fossils.
Fuel-based polymers are potentially cheap, and since they are biodegradable, they do not contribute to the growth of oceans and landfill sites.
It is also a replacement for existing bioplastics made using plant materials.
One of the most interesting parts of the study was that scientists used a kind of glycaptin found in DNA, as a construction block that can be adjusted to allow human cells to stick to the polycarbonate plastic above.
This will make it a scaffold for tissue engineering that can eventually produce manufactured human organs for transplant purposes.
