“…However, discovering biodegradable alternatives that meet specific property criteria, such as optical transparency, fire retardancy and mechanical resilience, presents substantial challenges. Current approaches rely on trial-and-error experiments and probe a broad range of parameters in a scattershot manner 4 , 5 . As more plastics are needed to be replaced, the time and cost required to find suitable biodegradable substitutes will increase.…”

One possible solution against the accumulation of petrochemical plastics in natural environments is to develop biodegradable plastic substitutes using natural components. However, discovering all-natural alternatives that meet specific properties, such as optical transparency, fire retardancy and mechanical resilience, which have made petrochemical plastics successful, remains challenging. Current approaches still rely on iterative optimization experiments. Here we show an integrated workflow that combines robotics and machine learning to accelerate the discovery of all-natural plastic substitutes with programmable optical, thermal and mechanical properties. First, an automated pipetting robot is commanded to prepare 286 nanocomposite films with various properties to train a support-vector machine classifier. Next, through 14 active learning loops with data augmentation, 135 all-natural nanocomposites are fabricated stagewise, establishing an artificial neural network prediction model. We demonstrate that the prediction model can conduct a two-way design task: (1) predicting the physicochemical properties of an all-natural nanocomposite from its composition and (2) automating the inverse design of biodegradable plastic substitutes that fulfils various user-specific requirements. By harnessing the model’s prediction capabilities, we prepare several all-natural substitutes, that could replace non-biodegradable counterparts as exhibiting analogous properties. Our methodology integrates robot-assisted experiments, machine intelligence and simulation tools to accelerate the discovery and design of eco-friendly plastic substitutes starting from building blocks taken from the generally-recognized-as-safe database.

Nowadays, researchers are striving to address the problem of plastic pollution by uses of edible films developed from food biopolymers. Biopolymer are a group of alternative materials made partly or entirely from renewable sources. The objective of this study was to create edible film from fermented coconut water. We called nata de coco (NDC). NDC resulting from the fermentation of Acetobacter xylinum bacteria in coconut water can be used as raw material for biopolymer because it contains cellulose compounds so it is called biocellulose. In this research, edible film was produced used mainly material is NDC. The method was manufactured using mixture and founding methods. Edible film based NDC also produced which is mixed with chitosan with a mass composition mass ratio of NDC and chitosan is 80:1 by varying the chitosan dissolved in acetic acid at 15 ml, 20 ml and 25 ml. The optical properties of edible film is become focused in this study. Based on UV-Vis spectrometer testing, samples obtained with a 15 ml acetic acid variant gave a transmittance value of 89%, while samples obtained with a 20 ml acetic acid variant gave a transmittance value of more than 90%. This high transmittance value shows that the sample of NDC-edible film obtained with variations of 20 ml of acetic acid has a high degree of transparency. Coconut trees are tropical plants that are easy to grow in coastal areas. Therefore, this plant is well known to the public considering that Indonesia is an archipelagic country and has spread out beaches. Indonesia is one of the largest coconut producing countries in the world, so research using coconut is very sustainable.

“…Due to its high cellulose content, OPEFB shows significant potential as a raw material for cellulosic-derived products, including cellulose fiber, 12,13 nano cellulose, 14 glucose, 15 xylitol and ethanol. 16 However, cellulose itself lacks plasticity, requiring modifications for its use in bioplastic production.…”

This investigation was centered on the intricate processes of fabricating and fine–tuning the concentration of microcellulose derived from oil palm empty fruit bunch (OPEFB). The objective was to employ it as a reinforcing agent, with sorbitol serving as a plasticizer, and chitosan acting as both a plasticizer and a strengthening agent for the formulation of bioplastic films to gain higher value mechanically. The cellulose extraction involved a methodical delignification approach, extracting lignin and hemicellulose from OPEFB to yield brown pulp. Subsequent double peroxide bleaching was employed to reduce the lignin concentration in the pulp. Leveraging the Box–Behnken experimental within a response surface methodology framework, the study scrutinized the influence of independent parameters (additive concentrations) on the ultimate tensile strength and Young’s modulus of the fabricated bioplastic films. Noteworthy variations in ultimate tensile strength and Young’s modulus were discerned, underscoring the impact of microparticle loading on the mechanical attributes of the bioplastic films. The quadratic polynomial model derived from experimental data exhibited coefficients of determination (R2) of 0.8690 for ultimate tensile strength and 0.6793 for Young’s modulus, affirming the adeptness of the models in navigating the optimization space. Microcellulose was isolated (30 – 40) wt.% of OPEFB as the white pulp which revealed a homogenous dispersion with chitosan in the corn starch matrix. The superior tensile strength and Young’s modulus were observed at 6.84 MPa and 21.94 MPa respectively.
