gaddemet. and so now, it`s again time for Science Investigatory Projects T_T we decided to make bioplastics from potato peelings [since we were told that any root crop is rich in starch (and that`s exactly what we`ll need) and secondly, bec the peelings are just waste products]
the prob is .. in our methodology. well, the teacher already and just corrected some technical errors but i`m guessing she didn`t have knowledge on the proper methods [or something] of course.
briefly, it`s like this:
1. Gathering of Potato Peelings
2. Extraction of Starch: making use of a blender?! is it just right?! T___T
3. Fermentation: using Lactobacillus *something*, from starch to lactic acid ? daaaaaaaaarn, and on a side note, how long does it actually take ? @_@
4. Filtration: bec the senior we consulted told us that the lactic acid is still unpure so we have to filtrate, is that correct?
5. Applying the *organic* plasticizer? .. yeah i think that`s it
daaaaaang u hafta help me with the detailed methodology T_T
