RESEARCH AND DEVELOPMENT In the early 1950 s, amylomaize (>50% amylose content corn) was successfully bred and commercial bioplastics applications started to be explored. In 2004, NEC developed a flame retardant plastic, polylactic acid, without using toxic chemicals such as halogens and phosphorus compounds. In 2005, Fujitsu became one of the first technology companies to make personal computer cases from bioplastics, which are featured in their FMV-BIBLO NB 80 K line. Later, the French company Ashelvea (also listed on EU Energy Star registered partners), launched its fully recyclable PC with biodegradable plastic case "Evolutis", reported in "People Inspiring Philips", a series of 3 minidocumentaries to inspire Philips employees with some examples from the civil society. In 2007 Braskem of Brazil announced it had developed a route to manufacture high density polyethylene (HDPE) using ethylene derived from sugar cane. In 2008, a University of Warwick team created a soap-free emulsion polymerization process which makes colloid particles of polymer dispersed in water, and in a one step process adds nanometre sized silica-based particles to the mix. The newly developed technology might be most applicable to multilayered biodegradable packaging, which could gain more robustness and water barrier characteristics through the addition of a nano-particle coating.
