4. The result of the polymerization is small pieces of raw material polylactic acid plastic which can be converted into an array of PLA plastic products. What are the benefits of PLA products? PLA requires 65% less energy to produce than traditional, petroleum-based plastics. It also emits 68...
The plastic paper is produced in a safe "clean room" at the Plastic Logic factory, which opened last month as the world's first plastic-electronics factory. Every part of the product, from the screen to the electronics, is made of plastic. And it is described by engineer Dean Baker as ...
. The average drinking water consumption in Italy has been estimated in 1.5 liters per day, corresponding to three 500 ml-plastic bottles and 1 refillable aluminum bottle. LCA has been firstly applied to a single bottle production and use, then to the daily and annual bottles consumption. PET...
PLA is made from ‘ingeo’ – which is a plastic pellet derived from corn by NatureWorks LLC. NatureWorks does not divert a significant amount of corn from the world food supply in making ingeo, but the company is still working to use other raw materials to create whatever the ‘next ing...

the brand new and improved PLA (Plastic-Lactic-Acid) Material. This green material, biodegradable PLA, comes from natural cornstarch which consists of normal plastic properties but without any negative effects from petroleum components. The carbon dioxide emission is 40% less than petroleum plastic!
3DThis may look like an ordinary plastic straw(吸管), but it is not made of plastic. Cameron Ross star-ted the Celise Bio-products company, to produce sin-gle-use plastic alternatives from plant materials likethese. They are made of poly lactic acid(聚乳酸)known as PLA from corn starch...
PLA (polylactic acid), for example, is made by adding enzymes to the endosperm of corn, which creates dextrose that is fermented into lactic acid, that is then converted to pellets of polylactic acid plastic. This is not a natural process, and the resulting material behaves nothing like the...
Unlike traditional plastics and bio-plastics such as PLA and PHA, CornNext-17 retains its natural polysaccharide structure, enabling rapid decomposition within 30 days in natural environments while maintaining the mechanical properties necessary for diverse applications. We all know that most plastics are...
