Rapid population increase and industrialization are the cause of the large use of disposable cutlery which in turn increases as solid waste. India is suffering from severe environmental contamination as a result of inappropriate trash disposal, particularly plastic waste. Many researchers are working on disposable methods for the safe disposal of plastic waste and also trying to find an alternative for disposable cutlery. From an environmental standpoint, we must abandon disposable tableware made of polluting plastic in favor of biodegradable and environmentally friendly alternatives. One such product which is popular these days is edible tableware but this project focuses on the material and its properties as well as on the process and mechanisms involved in making edible tableware that can be only eaten by livestock. To know more about the material 3d model of the tableware is made, it is assigned with different materials and properties then it is simulated on Ansys, and results are collected for comparing the material. This gives an idea for the artist working on making edible tableware for sustainable development. Edible plate with different materials serves a different purpose; wheat bran can be used in making edible plates that will be eaten by a human while plate which will only feed livestock can be made from wheat straw. Based on the analysis made through the study, wheat straw is the best material because of its raw material availability and cost-efficiency. By comparing how each material physical property is affected relative to the thickness of the plate, a 2.5mm thickened plate was the most efficient and produced optimal results in all the analyses from this we conclude wheat straw is the best option for making edible cutlery.

The objective of this project is to create biodegradable plastics for single-use and experiment with the different methodologies of production of biodegradable plastic and investigate its different properties of it. Central Pollution Control Board (CPCB) estimated the average plastic waste in India is around 6.92 percent of municipal solid waste. It is also estimated that by 2050, plastics could already be responsible for 15 percent of global carbon dioxide emissions. However, the main objective is to provide the methodologies to produce biodegradable plastics by using renewable biomass resources which will reduce the effects of plastic wastes in the environment. The project deals with various factors in the production of biodegradable plastics with a detailed survey on these factors. We hope to find an alternative to replace conventional petroleum-based plastics with biodegradable plastics which will be less harmful to the environment. [ABSTRACT FROM AUTHOR]

3D Printers produce physical 3D objects by printing layer by layer from digital data. The digital data in the form of CAD models can be obtained either from any advance CAD packages or scanned models from a 3D Scanner. Due to the extreme shortage of ventilators available in India and continues increase of corona virus patients' day by day there is a need of more ventilators. Five percent of patients who are suffering from corona virus need ventilator support for breathing. To overcome the shortage of ventilators, ventilator splitters were developed and it can be shared by many patients for oxygen supply. It can able to control flow of oxygen from the ventilator splitters to different patient's lung sizes. So in this research a ventilator splitter, design in CATIA software, Computational Fluid Dynamic (CFD) analysis was done using ANSYS16.0 and fabricated by process of Fused Deposition Modeling (FDM) using antimicrobial PLA material. Antimicrobial PLA is biodegradable plastic integrated with copper nano-particles, which will restrict the 3D printed parts contaminating bacteria's. So, copper nano-particles PLA can be used for producing ventilator splitters for splitting oxygen to the four patients at a time emergency situation in hospitals. From the CFD analysis it is observed that the oxygen maximum static pressure (1.058e +002Pa) is at inlet of the ventilator and minimum static pressure (-2.17e+002Pa) at outlet of the ventilator splitters. The maximum oxygen flow velocity is 2.121e+001m/s and there is no change of temperature of the flow. It is also seen that net mass flow rate and net heat transfer rate are 0.0032676226kg/s and -0.051416769w respectively. [ABSTRACT FROM AUTHOR]
