Cassava starch as an effective component for Ideal Biodegradable Plastic

Inventions have evolved and continue to evolve such that after several years of study, research and experimentation reach great developments. With continuing efforts to investigate the constituents of Philippine plants, we have pursued investigation of starch of the cassava plant (Manihot esculenta). Cassava tubers were gathered, ground and squeezed to extract starch. Starch obtained was weighed and divided into three equal parts; 80 grams in T1, T2 and T3.

Treatments also consisted of 60 ml plastic resin glue and resin with 50 grams of flour catalyst for T1, 100 grams for T2 and 150 grams in T3. The components in every treatment were mixed, stirred and then poured in silk screen with oil and then sun-dried. Test for capacity to carry weight indicated T3 as the best. For its ability to hold water, all products passed but for biodegradability, T1 gave the best results. The tensile and bending properties had been tested using the Universal Testing Machine and Analysis showed that T3 had the greatest tensile strength while T2 had the greatest bending property. Using ANOVA single Factor, results showed that there was significant difference among the three treatments in bending and tensile strength. However, for biodegradability test there was no significant difference. The final phase of the study determined the effectiveness of cassava starch as component of biodegradable plastic. Results confirmed that cassava starch is ideal as tests proved its worth.

  1. Do you any contact to commercial manufacturing plant for cassava to biodegradable plastic production.
    We have raw material in abundance and wish to commercial produce plastic material.

  2. Hello, I am curious to as how you did this experiment and what had urged you to make this kind of project. Is it okay if I knew more about it and possibly try to use and add more to it as my practical research for school?

  3. Hi! Good day! Uhm, I would like to adapt this I.P for our school project. Can I contact someone who have a copy on this?

  4. Hi! I am fully interested in this IP. Would you please be kind enough to email me the full copy of your paper? We are going to use this for school. Thank you in advance. :))

  5. Hi…me and my fellow researchers are interested on your idea…
    We are looking for a new topic and it is the most interesting one.
    Will please send us a full copy of it via my email?
    Im looking forward for your kindness….

  7. Good day, can I ask for a full copy of this IP? I really need this for school as thesis reference and I will definitely give proper citation. Thank you in advance!

  8. Interesting science investigatory project! Can i have a copy of the scope and delimitation and recommendations for possible related research? Thanks

    Respectfully yours,

  9. Hello! Good day po! Can I please have the full copy of this investigatory project?? please we will give you credits naman po.. and we are reallyy interested in this I.P. Can u just email me?? Thank you po talaga!

  10. Good day!! I would like to ask for the full copy of your IP, if you permit! It interest me and gave me an idea related about your IP. Thank you! ?

  11. Good Day! I wish to be able to know more information about this investigatory project topic. Would you be kind enough to send the full copy of this topic to me. I would be grateful if you did.

  12. Good day! Can I have the full copy or the recommendation part, I just need it for school works, you will be fully credited, thank you.

  13. Good day!
    I am very interested with your SIP and hopefully, I can adopt it using different starch. Can I please have a copy of your project?
    Thank you so much!
