WHAT IS THE BIOPLASTIC ?
2 There are several types of bioplastics, they can be agrosourced or biodegradable or both. Agrosourced polymers are not made from petroleum but from renewable biological raw materials such as vegetable matter. Biodegradable polymers can be derived from petrochemicals or biomass. Generaly the production and use of bioplastics are considered as a sustainable activity compared to the production of petroplastic. Bioplastic relies less on fossil fuels and also rejects less Greenhouse gases during biodegradation. The polylactic acid called PLA is the most commercially available bioplastic. It’s a biodegradable bioplastic obtained from the fermentation of corn starch. PLA is used in various sectors, from packaging to surgery and especially in the area of 3d printers. Compared to petroplastic, the PLA is more expensive to produce, twice the price and its technical properties are lower for now. That’s why PLA didn’t take the all market of plastic industry yet, its requires investments and biotechnologies advances.
Samples of bioplastic made with foam (gelatin base recipe)
In this book we are going to explain how to create his own bioplastic, a type of agrosourced bioplastic made from gelatin base. But there are many bioplastics make from renewable ressources like wheat, cornstrach, potatoes, milk...
