Japan‘‘s NEC Corp. intend to use a new type of biodegradable plastic for their notebook personal computer parts. Japan for Sustainability report that this biodegradable plastic is made from polylactic acid with kenaf fiber as a reinforcing material.
Conventional biodegradable plastics, or bioplastics, made from polylactic acid derived from corn and other plants are said to have some shortcomings, such as the susceptibility to thermal deformation and cracking. The kenaf fiber-reinforced bioplastic, however, has more than 1.7 times the heat resistance and strength than conventional bioplastics. This improvement enables this bioplastic to be used as a material for "dummy cards" inserted into memory card slots.
NEC has been developing bioplastics containing flame retardants that do not contain harmful chemicals such as halogen and phosphorus, aiming to put them to practical use by 2006. Furthermore, the company intends to replace about 10 percent of the plastics currently used for PC cases with plant-derived bioplastics by 2010. The latest development will be the first step toward that goal

Waste management poses challenges, but could unlock major environmental and economic gains
Every day, the city of Rio de Janeiro, one of the largest metropolises in the Southern Hemisphere, generates 17,000 tonnes of waste, ranging from large industrial debris to candy wrappers bought innocently at newspaper stands. While this waste presents a serious and urgent environmental challenge, it also fuels an increasingly significant portion of the economy, with benefits extending beyond financial gains. - When we look at developed European countries, many are already recycling between 40% and 50%, with some reaching 60%. From an economic standpoint, both recyclable materials and organic waste hold tremendous value - stated Adalberto Maluf, National Secretary for Environment and Environmental Quality at the Ministry of the Environment (MMA), during the Methane Forum: Climate Emergency Brake, at the Rio Nature and Climate Week. Citing a 2025 report, Maluf mentioned that Brazil literally throws away R$27 billion annually, while municipalities spend significantly more - R$45 billion - managing all this waste, often overlooking the environmental impact or economic potential buried in landfills and dumps. - We spend R$45 billion to collect and dispose of waste in landfills, yet we manage to recycle less than a third of the potential. I believe it will be necessary to review contracts, create performance-based remuneration mechanisms, and pay for both effectively sorted materials and those diverted from landfills - he added. According to the IBGE, 60.5% of Brazilian municipalities adopt some form of selective waste collection, and several initiatives serve as examples of how to manage city waste. In his panel presentation, Bernardo Ornelas, Project Coordinator at the Rio de Janeiro Municipal Urban Cleaning Company (Comlurb), highlighted Ecoparque do Caju, a national benchmark in waste management and recycling. There, received materials are sorted and can be used for biogas production, organic compounds for urban gardens, or human consumption, in the case of still...
