“…The results show good performance of the product obtained. In general, however, much bioplastic research is focused on the use of starchy-rich and renewable plant materials such as maize [24], potatoes [25], wheat [26], manioc, and vegetable oils [27,28]. However, the production of bioplastics from food precursors, in addition to the fact that it can often be costly, poses a further problem: obtaining bioplastics from food crops means taking away land and water from food production, which should be used for human consumption.…”

Sustainable Management of Organic Waste and Recycling for Bioplastics: A LCA Approach for the Italian Case Study

et al. 2021

The collection of the organic fraction in Italy recorded significant growth in the decade 2010–2019 (+74%) due to both the increase in the spread of separate waste collection as well as the increase in the biological treatment plants of municipal waste. However, within the organic fraction there remains a share of non-compostable material (NCM) (plastic, glass, aluminum, etc.), equal to ~5% of the total, which affects the efficiency of composting practices as well as decreasing both the yield and the quality of the final compost, causing a portion of organic material to be subtracted from composting and ending up in landfills. Therefore, the purpose of this work is to evaluate how the sustainability of the organic fraction collection and the amount of compost obtained in the composting plants could improve, following the use of biodegradable and compostable bioplastic bags (shoppers), in replacement for conventional plastic ones. The Life Cycle Assessment (LCA) and Carbon Footprint (CF) methodology was used for the assessment, comparing two different scenarios based on data relating to the collection of the organic fraction in Italy in 2019. Scenario 1 relates to the composting of organic material that also contains plastics, bioplastics, and non-compostable materials, while in scenario 2 the share of plastic material in the first scenario has been entirely replaced by bioplastics. The results show that scenario 2 assumes the lowest values for 15 impact categories out of the 18 analyzed, and, among these, in three categories it assumes negative values: ozone formation-terrestrial ecosystems (−1.64 × 10−2 kg NOX eq), ozone formation-human health (−8.50 × 10−3 kg NOX eq), and fossil resource scarcity (−4.91 × 102 kg oil eq). Furthermore, scenario 2 has a negative carbon footprint (−3.80 kg CO2 eq) compared to scenario 1 (79.71 kg CO2 eq), and in general it is the most sustainable scenario as a direct consequence of the greater amount of compost obtained (307.4 kg vs. 269.2 kg).

“…Ghanbarzadeh et al found that the films made based on pure starch are brittle and fragile, especially compared to films made from cornstarch, which has a lower concentration of amylose content [16]. D. Amalia et al In (2020) He used cornstarch derived from corn and ground corn husk as base material and filler, respectively to improve the mechanical properties of bioplastic [17]. M. K. Maricela et al In (2019) studied BOP based on rice starch and cornstarch packaging applications, various bioplastic films are synthesized with diverse formulations such as starch, gelatin, citric acid, and glycerin.…”

Chemical-base polymers are mostly related to environmental pollution since their poisonous, non-biodegradable wastes, and negatively impact plants, animals, and people. In many locations where petroleum-based plastics are used, bioorganic polymers and biomaterials can play a promising role and are accepted. In one such attempt, glycerol was used as a natural plasticizer, and cornstarch was used to create bioorganic polymers and biocomposites. Resulting in a highly degradable bioorganic polymer in water and soil, display FE-SEM images of a BOP's top and cross-section views, flat surface and smooth, the inner structure of BOP does not demonstrate any bubbles, cracking, flipping, or splitting., estimate the optical band gap indirect of BOP of 3.69 eV that can absorb 96% of UV light and transmit 98 % of visible light. The FTIR assay detects the functional aggregates of the BOP as well as the presence of a hydrogen bond in the BOP matrix. Raman spectroscopy detection composition and scope distribution of the various components in a prepared BOP. The decay constants of BOP were gaged as 12.4 ± 1.8 and 3.49 ± 0.41 for the water and soil, respectively. The decay values show an acceptable variation due to the nature of the BOP on one side and the water and soil on the other side. These findings conclude diverse applications highlighting BOP as a candidate, e.g., UV screening or protective layer, food packaging, and replacing the chemical fertilizer with BOP agent to deliver the organic substances to the plants.

“…It can strengthen biopolymers, improve mechanical properties and reduce the high-water sensitivity of bioplastic layers [5]. Chitosan is usually used as a preservative and can increase the number of hydrogen bonds in the polymer chain, where these bonds contribute to the overall strength of the bioplastic [6]. Meanwhile, kaolin also plays a role in improving the mechanical properties of bioplastics based on increasing the barrier properties of CO2, O2, and moisture [7].…”

Characteristic comparison of cornstarch-based bioplastics using kaolin, microcrystalline cellulose and chitosan as fillers

2022

In the study, the basic material for making bioplastics was corn starch with the addition of kaolin, microcrystalline cellulose, and chitosan as filler variations, as well glycerol as a plasticizer. The method used was the blending method. The characterization included the absorption test for water resistance, biodegradation test, tensile and elongation strength test, and functional group analysis using FTIR. Among fillers, the best bioplastic characteristic bioplastic was obtained with filler kaolin with the water absorption value of 88.62%, a tensile strength value of 1.44 x10-3 MPa, and the elongation strength value of 5.04%. Nearly 80% of the material was degraded in 15 days. Spectra of FTIR showed the appearance of some functional groups from starch, filler, and plasticizer, which meant that the process of bioplastic manufacturing was physical mixing.
