World's first bioplastic computer cases

  • In August 2005, Fujitsu and Toray industries jointly developed a large case made of bioplastics for Notebook "FMV-BIBLO NB80K".

  • This bioplastic is made from polylactic acid derived from fermented starches and sugars from corns and potatoes. This new technology can reduce by about one liter the consumption of petroleum in the production of a notebook personal computer.

  • For some people, using food for industrial material may not be justified while there is a full of hunger in the world. However, the quality of such corns and potatoes for producing bioplastics is so poor that they are not suitable even for feeding animals. In that sense, bioplastic production is a way of utilization of wasted agricultural produce.

  • About 50 percent of the newly-developed plastic consists of natural materials, and it can reduce the consumption of petroleum resources. When used in the case of notebook computers, it can reduce carbon dioxide emissions by about 15 percent over the entire product life-cycle, compared to conventional petroleum-based resins.

  • Fujitsu does not raise the price of the notebook computer made of bioplastics, even though the production cost increases by applying bioplastics. Keeping the same price as conventional notebook computers is the "investment for the future". By doing this, the company aims to increase the sales of bioplastic products and to bring the cost down accordingly.

  • It is expected that bioplastics will be applied to more products in the near future as more and more companies have launched polylactic acid production. In addition to computer cases, plant-based plastics have been introduced to some equipments including printers and ATMs.

  • Fujitsu focuses on developing computer cases to challenge the difficulties to apply plant-based plastics. Currently it is not possible yet to produce computer cases made of 100 percent of plant-based materials due to their insufficient durability as well as heat and flame resistance. Therefore the company uses the material which is half-and-half mixture of petroleum-based resins and plant-based plastics. Once succeed in developing the bioplastic durable for computer cases, Fujitsu is going to expand its application to other appliances.

  • In addition to environmental reasons, Fujitsu is engaged in bioplastic development to reduce oil dependency. Developing alternative resources to oil is a proactive approach to respond to possible oil depletion in the near future as well as to secure the business less susceptible to the fluctuated oil prices.

Electronic paper displays
  • On June 13th of 2005, Fujitsu has developed electronic color paper that can be used without requiring electricity.

  • Here are some features;

  • Substrate newspaper to E-paper, just download the day's news from the vending machine and read it on your ultra thin, film substrate newspaper.

  • Plays big role like old newspaper but except throwing it away after reading it, you just need to update the content next day (rewritable color e-paper)

  • Lightweight, flexible, low energy consumptions and color displays

  • Highly reflective cholesteric selective reflection technology, up to 50 percent of incident light in specific wavelength and color is reflected.

  • Maintains color without power.
