Preparation of Foamed Packaging Materials from Domestic Garbage

A research team formed by the Faculty of Engineering at Fukuoka University in Japan and nine other companies has successfully manufactured foam packaging materials using household waste and food waste discharged from factories as raw materials.
The raw materials for preparing such foam packaging materials include tea residue, beer slag, bean curd residue and the like. By drying and pulverizing the waste residue, adding polylactic acid and water, and applying pressure, a foamable packaging material that can replace foamed styrene can be produced, as well as a buffer material for transporting articles.
The use of foamed styrene as a foam packaging material makes it difficult to decompose even if it is buried in soil after disposal. This kind of polymer foam can not only be completely decomposed into water and carbon dioxide in the soil, but it will not produce toxic gas if it is burned, and its cost can be reduced to the price level of ordinary foamed styrene. Therefore, there is a wide range of Application prospects. (Today to)
