Japan‘‘s Fujitsu Ltd, Fujitsu Laboratories, Ltd., and Toray Industries Inc. succeeded in joint development of a large case made of bioplastics, featured in Fujitsu‘‘s spring 2005 models of notebook computers, named FMV-BIBLO NB80K. Japan for Sustainability reports that this is the first time in the world that bioplastics made from corn starch were used in computer parts. The new technology can reduce by about one liter the consumption of petroleum in the production of a notebook personal computer.
In June 2002, Fujitsu and Fujitsu Laboratories jointly developed a plant-based material mainly composed of polylactic acid, to be used in the manufacture of notebook computer cases. Problems with durability and flame resistance were obstacles to further applications, however. Toray‘‘s participation made it possible to use this new material, a one-to-one mixture of durable petroleum-based resins and plant-based plastic, in about 60 percent of the computer casing, including the back of the display and the bottom of the main body, making the whole product more biodegradable.
Though the cost of the new material is about three times higher than that of conventional materials, there will be no substantial increase in manufacturing cost, as the cost of mass production, including molding, remains unchanged. This biodegradable plastic can be recycled after use. Its use can result in a reduction of carbon dioxide emissions by about 15 percent over the entire product life-cycle, compared to conventional petroleum-based resins.
The three companies intend to continue efforts to reduce their environmental burden and lower the consumption of petroleum resources by further expanding the application of bioplastics

Egypt reviews Red Sea waste management system – Dailynewsegypt
Egypt’s Minister of Local Development and Environment, Manal Awad, and Red Sea Governor Walid El-Barqi held an extensive meeting to review the performance of the governorate’s waste management system and discuss measures to improve environmental services and operational efficiency. The meeting, held during Awad’s visit to the Red Sea Governorate to mark World Environment Day, focused on assessing current challenges facing waste collection, sorting, recycling and disposal operations, as well as identifying priority actions to strengthen the system’s performance. Awad stressed that the government places significant importance on developing an integrated waste management system in the Red Sea Governorate, given its strategic importance as one of Egypt’s leading tourism destinations. She emphasized the need to comply with environmental and technical standards governing sanitary landfills, waste treatment facilities and environmentally sound disposal practices. During the meeting, officials reviewed the current status of waste management operations in Hurghada, including collection, transportation, sorting, recycling and final disposal activities. Discussions also covered the infrastructure upgrades required to improve system efficiency and ensure the proper operation of sanitary landfill facilities. Yasser Abdullah, head of Egypt’s Waste Management Regulatory Authority, presented updates on temporary waste collection and sorting sites and outlined measures to strengthen operational management and oversight. He highlighted the importance of improving monitoring mechanisms for waste handling activities and maximizing the recovery of recyclable materials while reducing informal and unregulated practices.
