Abstract:This study evaluated the modification of bioplastics production by various ratios of sorghum starch and cellulose from red seaweed eucheuma spinossum, and the use of glycerol as plasticizer and sorghum stalks as filler. Solid-liquid matrix transition should be far over the operating temperature of gelatinization and extracted at 95 o C in order to avoid the loss of conductivity. The analyzed variables were starch and cellulose seaweed eucheuma spinossum and the addition of variation of filler. Sorghum stalk ad… Show more
“…8 ) with powdered potato peels and wood dust as filler respectively presented similar results where samples with no filler added (except control) demonstrated the lowest absorption of water capacity whilst addition of filler demonstrated a steady increase in the water absorbance capacity. In a study by Darni et al, ( Darni et al, 2017 ), similar results were also noticed in which absorption of water was seen to increase when sorghum stalks filler was added into a sorghum starch based bioplastic. This can be attributed to sorghum stalks comprising of cellulose, and cellulose being hydrophilic.…”

“…Pretreatment of fillers was done using slightly modified two similar methodologies of Darni et al, ( Darni et al, 2017 ) and Moro et al, ( Moro et al, 2017 ). Both the potato peels and wood shavings were reduced in size using scissors, followed by drying in oven at 90 °C for 5–6 h and then powdered in a blender.…”
With the ever-increasing demand of plastics in the world and their consequent disastrous effects on environment, a suitable environmental-friendly substitute like bioplastics/biodegradable plastics is the need time. This study centers on green-production of a variety of bioplastic samples from (1) banana peel starch (BPP) and (2) a composite of banana peel starch, cornstarch and rice starch (COM) with varying amounts of potato peel powder and wood dust powder as fillers, respectively. Two different plasticizers – Glycerol and Sorbitol – have been utilized separately and in a 1:1 combination. A total of 12 samples of each of two types of bioplastics were made using multiple amounts and combinations of the fillers and plasticizers, to test the differences in the physical and chemical characteristics (moisture content, absorption of water, solubility in water, solubility in alcohol, biodegradation in soil, tensile strength, Young’s modulus and FT-IR) of the produced samples due to their different compositions. The differences in the properties of the bioplastic samples produced make them suitable for usage in many different applications. All 24 of the samples produced were synthesized using natural and environmentally safe raw material and showed biodegradation, thus proving to be a good alternative to the conventional plastics.

“…Bioplastic production using raw materials for empty bunches has been successfully carried out using modified cellulose, composites with plasticizers and compatilibizer [2]. The results of studies conducted by bioplastics were produced using starch and cellulose of seaweed eucheuma spinosum and the addition of sorghum stem fillers, which are thought to affect the mechanical and physical properties of bioplastics [8].…”
The purpose of this research is to obtain bioplastics that are biodegradable and safe if disposed of in the environment. This bioplastic is made using Empty Bunches and white rice and plasticizer. White rice flour as a source of starch with variations in the addition of chitosan additives and glycerol plastilizer. The analysis of the biodegradable plastic products produced was tested for physical and mechanical characteristics such as thickness, water resistance test (%), biodegradation rate (%), and tensile strength (MPa). The method used is by mixing the starch from the mixture of empty bunches and white rice and adding glycerol and chitosan plasticizers. The mixture is heated at a temperature of 70 -80 0 C for 60 minutes. Data from the analysis of Biodegradable plastics products showed that the more glycerol and starch added, the greater the tensile strength and the percentage of elongation. Bioplastics produced From the data, it can be seen that 1.2 grams of chitosan has the best water resistance compared to the others, which is valued at 78.02%. This is due to the hydrophobic nature of chitosan and insoluble in water. So, the greater the chitosan concentration, the greater the % water resistance and the better the plastic resistance to water.
“…Several research groups are making efforts to replace petroleum-based polymers by natural, biodegradable, and abundant products synthesized from renewable biomass [10,11]. Various biomacromolecules are present in nature, which could be utilized as renewable biomass for the production of nanohybrid materials such as starch, cellulose, lignin, polylactic acid (PLA), and other polyesters for the development of "greener" materials [12,13]. Their blends with natural inorganic materials, for example, nanocellulosic-clay and carboxymethylcellulose, provide enhanced biodegradability and biocompatibility among matrix molecules.…”
This chapter presents a broad overview of the current advancements in bioplastics and bioinspired nanocomposites with nanoscale reinforcements that are being applied for a broad range of applications, that is, biomedical, electronics, durable goods and packaging materials. The production of nanocomposites by completely and/or partially renewable and biodegradable materials has helped in a range of different applications. Several drawbacks of conventional materials such as hydrophilicity, low-heat deflection, poor conductivity, and barrier properties can be efficiently overcome using biohybrid nanomaterials. Nano-reinforcements in composite materials deliver remarkably improved properties such as decrease in hydrophilicity and increase in mechanical properties as compared with neat biopolymer, which fails to exhibit these properties on its own. This approach can be used for other natural polymers to induce desired functionalities. This chapter covers the recent trends in nano-functional materials, renewable materials that are being applied for the production of nanobiocomposites and their applications especially in biomedical and healthcare sectors, which are discussed in detail. This emerging concept will definitely enhance the scope of nanohybrid materials for sustainable products development with improved properties than previously applied synthetic polymer-based or natural polymer-based materials.
