Flip-Flops with pellets
1. Introduction
This project focuses on the design and production of sustainable flip-flops by reusing plastic pellets collected from beaches, combined with a mixture of rubber. The initiative is part of the BlueTech Competition, organised by the European Union, which aims to promote innovative solutions for marine conservation.
The project seeks not only to reduce plastic pollution, but also to apply technical drawing skills in the development of a functional and eco-friendly product.
2. Objectives
The project’s objectives are divided into two main areas:
Firstly, it aims to practise and apply technical drawing knowledge through the creation of 3D models for the flip-flops’ production.
Secondly, it strives to actively contribute to the fight against marine pollution by reusing plastic waste.
Additionally, the project aspires to present an innovative solution within the competition, standing out in the field of technologies for ocean preservation.
3. Methodology
The project’s development process was structured into several stages.
First, research was conducted to identify the best options for reusing plastics, ultimately selecting flip-flop production as the optimal solution. Next, tests were carried out with different proportions of rubber, pellets and different types of silicone to achieve a mixture with the desired properties: elasticity, wear resistance, lightness, and comfort. In order to create the strap, we worked with textile waste .
The flip-flops’ design was created using Tinkercad, producing a 3D template adjusted to the largest foot size in the group (EU 45). Due to the limitations of the 3D printer, the mould was split into two parts for printing.
Finally, the prototype was manufactured using rubber silicone as a base and incorporating plastic pellets collected in collaboration with the NGO Good Karma Projects.
The first prototype was successfully produced on 25th April, confirming its viability.
4. Planned collaborations
To enhance and scale the project, collaborations with specialised institutions are planned. Good Karma Projects would continue supplying plastic pellets and promoting the initiative.
Chemists and materials technologists, to provide support in:
- Studying the strength and sustainability of recycled materials.
- Improving design and manufacturing processes.
- Developing bioplastics or alternative compounds with lower environmental impact.
Additionally, partnerships with bioplastic companies will be explored to investigate even more sustainable alternatives for the flip-flops’ composition.
