You can make bioplastics from... (part 6)

A new publication, the Journal of Renewable Materials, will be coming out with its first issue in December (and it’s accepting unsolicited online submissions here). As a peer-reviewed journal of research, obviously it will be much more in-depth than the occasional coverage and links I present in this series of blogs on bio-based materials.


Still, the abundance of related news, like the items below, makes it clear why such a journal is needed. So much research is waiting to be done, and published, about the use of materials from relatively mundane renewable materials like these....


Bamboo: Along with the abbreviation for “WPC” for wood-plastic composites, perhaps we should get used to using “BPC,” for bamboo-plastic composites (or at least “GPC,” since bamboo is actually a grass). A 60% bamboo/40% HDPE formulation for decking has been developed – with both components reportedly being 100% recycled, using post-industrial bamboo from the company’s other products, and HDPE from recycled containers.


Meadow grass: In more grass-related news, a German company has created AgriPlastic, a lightweight composite that combines 40-75% meadow grass and 25-60% recycled plastic. The grass is produced during farmers’ crop rotations, according to the report. Injection-molded products for the material are said to include “spoons, brackets, machine cases, and protective caps” – quite a variety.


Weeds: Finally, the title “Rubber from Dandelions” says it all. Latex derived from cultivated dandelions serves as yet another form of bio-sourcing, and this cultivation, collection, and conversion into latex has actually been done in Europe since World War II. Moreover, a lot of other common plants also produce latex, according to the “wiki” cited above.


Watch for future parts to this series covering cellulose-based materials, and even developments in resins made from the greenhouse gas CO2.
