Environmental Impact on Biodegradation Speed and Biodegradability of Polyethylene and Ipomoea Batatas Starch Blend

Abstract

All over the world, even in developing countries, plastics have quickly become one of the most common things found around. Unsurprisingly, this has caused a major waste management problem, particularly because synthetic polymers do not break down and degrade like organic waste. As a result, an alternative is being sought out in biopolymers. This study explores the suitability of a biopolymer blend;Ipomoea batatasmixed with low density polyethylene (LDPE) at various compositions. Biodegradation of this biopolymer blend was observed periodically when produced samples ofIpomoea batatas/LDPE were buried in loamy sand over a period of 28 days. Results show that produced biopolymers are environmentally compatible and bio-degradable. It was also observed that the sample blend with equal portions by weight ofIpomoea batatas(50%) and LDPE (50%) showed the most optimum pattern of degradation. There was steady degradation over the study period and the rate of degradation observed showed sustainability.

Effects of Plasticizers on Mechanical Properties, Oxygen Permeability, and Microstructural Characteristics of HPMC/Beeswax Composite Film

“…Glycerol films decreased the TS values from 9.63 MPa to 3.81 MPa, meanwhile, the EB values increased from 10.61% to 24.63%. The results are similar to other publications on different biofilms [10][11][12][13][14][15][16][17][18][19][20][21]. Besides, when the content of PG was increased, the EB values also rose from 9.82% to 19.21% and the values of TS reduced from 10.12 MPa to 4.25 MPa.…”

“…As a result, free volume was formed to allow the oxygen easily transmit through the films. Therefore, it is able to evaluate the impact of plasticizers on the oxygen barrier properties of HPMC/BW composites [5,[7][8][9][10][11]. Additionally, plasticizers improve films homogeneous to produce smoother films that have the surface roughness, adhesive failures, and fractured surfaces of composite films detected by scanning electron microscope (SEM) before and after adding plasticizers [11].…”

Green Cosmetic from Natural Colorant of Anthocyanin Extracted from <i>Ipomoea batatas</i> L.

“…The green cosmetics are natural original products containing compositions from botanicals and fruit-based materials [12]. Natural colorants are widely used not only in the food and beverage industries, but also in the pharmaceutical and cosmetic industries [13][14][15][16]. Natural colorants are extracted or processed from naturally occurring organic (plant or animal) materials.…”
