A basic component in the environmental strategy of Fujitsu is supporting product recycling so as to protect the environment. This report describes the use of biodegradable plastics in the shipping materials of electronic parts. It is essential for Fujitsu's strategy that shipping materials, such as LSI trays, can be reused to complete the recycling system, which consists of the following stages: production, distribution, usage, collection, and waste. Biodegradable plastics for LSI shipping materials were developed for the case where these materials might drop out of the recycling system. These materials have to be suitable as shipping materials and also have to maintain their biodegradability.
