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

Making use of Sludge by Bacteria to produce Biodegradable plastics.

                                               

 Articles constantly spoke about the human kind's effort to heal our planet in its various issues. A sustainable raw material for bioplastics to heal the planet from Single-use plastics is one such search. What if the raw material is produced using the huge industrial wastes that get discarded mindlessly.  The researchers found these very significant results in Sludge wastes.  Industries produce tons of sludge wastes which was a major concern. Though the sludge wastes get recycled, tons of these wastes end up in landfills. 

 So what could be done with this sludge wastes?  The main process with sludge is done with microbes. The earlier articles spoke about microbes capable of producing polyhydroxybutyrate (PHB) an alternative biopolymer for single-use plastics. Zobellella denitrificans ZD1 are gram-negative, facultative anaerobe which was identified and isolated from the salt waters of Mangroves region is identified as an efficient polyhydroxybutyrate (PHB) producer. PHB is the energy reserve for the bacterium under controlled conditions.

Similar research with the byproduct of biodiesel showed the possible PHB production until when the fatty acids in the byproducts affected the microbial growth. So the researchers considered the possibilities of impure fatty acids in the sludge to negatively affect the growth of the microbes, but so far with the lab testings with these microbes and fatty acids only had a positive outcome with the PHB production. 

Using the Sludge and Zobellella denitrificans ZD1 can act as a waste management process also as the cost-efficient method for Bioplastics production.
