What is PLA Plastic material?

Today’s serious environmental problem has generated in our society the need to find a new model of production and consumption that is more responsible with the planet. Among others, waste generation has been one of the causes that has led to the fact that today we have to face the problems of climate change.

In response this situation, alternative materials to conventional plastic have appeared that can play a fundamental role in the transition to a circular economy. PLA plastic is produced by the polymerization of lactic acid, which can be obtained through anaerobic fermentation of carbohydrates or by chemical synthesis.This acid is obtained in two consecutive steps: Lactic acid synthesis, Polymerization. Primarily, commercial lactic acid is derived from the fermentation of sugars by bacteria. This, therefore, means that the first step for carbohydrate fermentation is the extraction of sugar (glucose, lactose and maltose) or starches produced by corn, sugar beet and potatoes by a milling process.
