###### Abstract
[23] determined the bruised area of pear fruit with three different ripeness levels: unripe, ripe, and overripe. The authors experimented with the drop test at three different height levels, two orientations, and various impact surfaces. [PERSON] et al. [3] analyzed the stress and strain performance of pear fruit exposed to drop scenarios. The authors also evaluated the impact of dropping the pear fruit on steel, wood, Perspex, and rubber at different drop orientations on contact force and stress and strain distributions. [PERSON] [12] utilized the drop test method to evaluate the bruises of pear fruits of Ankara variety at different impact platforms, drop heights, and orientations. It was found that the minimum bruise susceptibility was dropping the fruit on a rubber-based platform with a 45-degree orientation at one-meter height. The impact damage index of Pucheng crisp pear fruits was investigated using drop impact tests of pear fruits throughout the harvest, transportation, and processing stages [16]. Factors including pressure area and average pressure were found to be associated with the severity of bruising. In this work, a drop impact FEA-based test was developed for the pear fruit-shaped FE model instead of the round-shaped pear fruit model to accurately predict pear fruit bruises [24]. The developed FE model will be evaluated with an experimental model, which was presented in our previous work [25]. Polyethylene terephthalate (PET) plastic is the most commonly used plastic around the globe, and it is used in containers and bottles for liquids and food. Inappropriate disposal of waste bottles takes hundreds of years to decompose in the environment and would harm wildlife and marine and human ecosystems. Significant efforts and initiatives are being settled in order to recycle and reuse plastic waste, such as the Reform company and the Belgian Yuma company, which produce sunglasses out of recycled polymers, and the US Army and marine research laboratories, which are repurposing plastic waste to 3D print it [26]. PET-based plastic waste bottles can be reused and converted into a 3D printing filament, which contributes to gaining environmental benefits and removing wastes from streams. This would close loops in supply chains and achieve a circular economy. Recycling PET represents a great candidate for promoting a circular economy. Waste bottles are collected, cleaned, and then melted and reformed into filaments, which can be used to produce a variety of products, including clothing, textiles, spare parts, and electronics. Through recycling PET, the focus of the circular economy is to keep materials in the loop, and products should be in use as long as possible. The proposed study is set out to propose a packaging design for fruit made up from 3D printed recycled PET. The goal is to minimize fruit bruises and improve shelf-life by making use of plastic waste to print cushioning design for pear fruits. The FE model used to model the fruit drop test and quantify the bruise susceptibility was validated with the experimental setup presented in our previous work [25]. The literature lacks cushioning systems and packaging designs for certain fruits that have soft textures, such as pears or fruits that are irregular in shape. Research has proven that package type would greatly impact the cushioning performance of pear fruits [27]. Furthermore, PET-based packages have proven their performance in reducing post-harvest damage and minimizing bruises on Andean blackberries [28]. Customized designs of biodegradable or reusable packages would minimize fruit losses and damage in the post-harvest supply chain [2]. Indeed, more research is needed to explore biodegradable, well-cushioned materials to replace existing ones [14]. The use of plastic packaging is increasing thanks to its reusability and recyclability. Therefore, optimization and customization of packaging designs would mitigate fruit damage and loss.
