Thermal Degradation and Mechanical Characteristics of Sugarcane Bagasse Reinforced Biodegradable Potato Starch Composites

Abstract

Global pollution due to the overwhelming usage of non-biodegradable plastics is getting severe nowadays. Hence, the aim of this paper is to develop an environmentally friendly composite material from potato starch and sugarcane bagasse. The composites were prepared by hot pressing at 145? for 60 min. The composites were characterize for their mechanical and thermal properties. In terms of thermal properties, thermogravimetric analysis shows that incorporation of sugarcane fiber has improved the thermal stability of the composites. Meanwhile, incorporation of sugarcane fibre form 0 to 15 wt.% has significantly improved the tensile and flexural properties of the composites. Scanning electron micrograph of the tensile fracture showed the fibre fracture and fibre “pull-out” from the composite. Overall, the biodegradable composites has shown improved functional characteristic than the origin material. This finding shows that this Sugarcane/Potato starch composites are potential alternative material for biodegradable product i. e biodegradable plastic packaging.

Effect of Cymbopogan citratus Fibre on Physical and Impact Properties of Thermoplastic Cassava Starch/Palm Wax Composites

“…In comparison to the TPCS/PW control sample, the sample containing 60% CCF content exhibited the lowest water uptake and thickness swelling after 2 h of immersion, decreasing by 54.24%. This finding can be attributed to the presence of fibre in the composites, which possesses a more rigid structure than starch, providing higher dimensional stability to the composites [ 65 ]. This study’s findings agree with those of a prior investigation into composites made of cassava starch and green coir fibres [ 66 ].…”

Microbial bioconversion of food waste to bio-fertilizers

“…83 Another biodegradable composite has been obtained from the waste of potato and sugarcane bagasse. 84 Cellulomonas sp., Klebsiella sp., Proteus sp., Enterobacter sp., and Salmonella sp. have been used to obtain organic compost.…”

State of Knowledge on Starch as an Alternative Solution to Petrochemical Resources—A Review

“…Jumaindain et al [5] Studied the composites made from the stems of banana leaves, the molding was done by thermo pressing to obtain biofilms 3 mm thick.…”

“…This is due to the fact that the creation of plastic-based products is very easy thanks to its characteristics of low cost, convenience, lightness and satisfactory elegance which make them very necessary materials. However, there are negative effects on the environment caused by the use of these non-biodegradable plastics generated from petroleum resources such as the depletion of fossil resources, the re-lease of carbon dioxide, environmental pollution, destruction of the ozone layer, the risk of human health toxicology and the increase in the price of oil [3] [4] [5]. To solve these problems, several avenues have been carried out to explore alternative solutions to materials plastics from petrochemicals.…”
