Recycling low-density polyethylene using waste plastic bottles for 3D printer filament production via fused deposition modelling

The release of millions of tons of waste plastic into landfills, oceans, and ecosystems around the world has resulted in the emergence of plastic pollution as a global environmental problem. The low-density polyethylene (LDPE), a large component of these plastics, is present in most of these plastic bottles and has been thrown away. Using Fused Deposition Modelling (FDM), this project aims to find a solution to this problem by reusing discarded LDPE bottles into high-quality filament that can be utilized for 3D printing. The objective of the effort is not only to lessen the burden of plastic trash, but also to contribute to a circular economy, which is characterized by the reuse of resources and a reduction in reliance on natural polymers. In order to comply with global sustainability goals and to promote a more ecologically conscious approach to manufacturing, the initiative encourages the utilization of LDPE, which is derived from trash bottles, and transforms it into a valuable resource for 3D printing in Bangladesh.

It is the goal of this project to demonstrate the possibility and effectiveness to produce high-quality 3D printer filament from recycled LDPE by conducting extensive research, developing novel processes, and conducting rigorous testing. In addition to this, it intends to evaluate the economic viability of such an initiative while highlighting the significant environmental benefits that it would bring.
