Constant change and a tiny step.

                   Finally a breathing space, realization during these period is that changes are constant , changes never change.  Little steps taken for a healthy environment can also make a better difference. Milk packets:          Recently I came across few articles and posts , that opening the milk packets without cutting off the tip  and just having a slit without separating  the small piece can reduce the number of small plastics entering the soil which never gets decomposed. Karnataka has encouraged citizens in this method. This can be used in any plastic covers we use in our day to day lives.           I hope we could implement this small step.            Comment on if you got any more ideas

From Food wastes to Biodegradables!

                Soil waste management, industrial waste management approaches for biodegradable plastics were the topics that were discussed in small parts. To add more sugar, many articles spoke about the use of  Kitchen wastes as Carbon and Nitrogen sources for biopolymer production. With the PHA production from Bacillus subtilis, Watermelon peel and pulses peel were used as the basic Carbon and Nitrogen sources.

              Fruit wastes generated also processed to produce powders that can act as bioactive compounds like polyphenols. anthocyanin, pectins which are the significant sources for biodegradable plastics. The very first article gave Banana peels with Corn starch is also a major byproduct.

               The winemaking wastes which are the sugary bases are experimentally verified as a significant source of producing biodegradable plastics. Another important food waste is the Potato juice extract said to be a suitable product for biofilm extract.

Before getting into more exemptional food byproducts, some common food byproducts are  rice, soya beans, cassava husks residues as the source of starch, shrimp husks for chitin

Lists of some Valuable food wastes:

  • Meat and fish wastes from slaughterhouses and fisheries.
  • Sugar wastes from sugar manufacturing industries.
  • Coffee husks, edible oil, grains wastes from processing units.
  • Dairy factory wastes.
  • Beverage industrial wastes, both alcoholic and non-alcoholic.
Significant characteristic extracts from the wastes:
  • Favorable amount of Lipid content.
  • Nitrogen and Carbon source. 
  • Carbohydrates, minerals, water contents, cellulose, fatty acids, etc.
The increasing bioplastic raw materials sources and manufacturing approaches provide very high hopes. If yes, then what is the delay?.  Are all these manufacturing processes cost-effective?
