Question

So we are designing a product which can replace plastic straw. We are proposing keratin based bioplastic film from chicken feathers since its biodegradable as an alternative of current plastic straws. Ill send you my report from phase 2 where I mentioned more about it. (there are 3 phases and now im working on the third phase. Below I have attached report from last year which is phase 3 and also attached my report from phase 2. I need the following from you:

Also, I have attached lecture slides which explains more about it. If you have any questions, feel free to message me. Thanks

Process flow diagram for Keratin Process
The process flow of producing keratin protein based bio straw is schematically represented below,
The chicken feather from local storage unit are transferred to mixer unit through conveyor belt and 1 N sodium hydroxide an base is added along with chicken feather in reactor cum mixer unit. Through reactor jacket hot water system is used for maintaining the temperature of process at 50oC and stirred/mixed at 1.5 m/s tip speed for 4-5 hours for complete separation of keratin protein from feather. The mixture is drained into stainless steel grade filter for separation of protein solution from aqueous phase by maintaining the mixer tip speed at 0.3 m/s for complete suspended drain.
The filtered keratin protein is stored locally momentarily for next process and rest of content from SS filter are drained / discharged. In other hand the PA granules are dissolved completely in mixer using distilled water (or) milliQ water since milli Q water is not economical at industrial scale we will be using in-house distilled water for this dissolution step. The dissolved PVA are added with 10% glycerol solution and mixed continuously to attain virtually no layer separation i.e., complete dissolution. From Arun et.al journal it was shown that by adding microcrystalline cellulose at minimum amount of 2% doubles the strength of product mechanically.
