What are Bioplastics? They've been around a while...

 Bioplastics are plastic materials made from biomass sources such as corn, starch, straw, woodchips and so forth. The first bioplastic was discovered in 1926 by Maurice Lemoigne. It is known as PHB (polyhydroxybutyrate). One hazard of bioplastics is the production on methane gas on decomposition.

Fiberglass (US) or Fibreglass (UK)

Fiberglass is a material also known as "glass reinforced plastic" i.e. plastic reinforced with glass fiber (extremely fine fibers of glass). It is cheaper and more flexible than carbon fiber. Fiberglass is manufactured using pultrusion.
