Abstract: Plastics created from fossil fuels are quite widespread in our lives, and we cannot imagine our existence without them. At the same time, they are non-biodegradable and emit greenhouse gases, posing an environmental issue. Biodegradable bioplastic is the solution to this issue. Plastics created from renewable biomass sources, such as vegetable fats and oils, corn starch, pea starch, or microbiota, are known as bioplastics. Bioplastics can be made from a range of sources, including starches, cellulose, and other biopolymers. In this work, we will discuss the production of bioplastics from cellulose, with waste papers serving as our raw material and the pH sensor serving as our feedback control mechanism.
