CASE STUDY 3 – Recycled Plastic 3D Printing

Case study intent: To demonstrate the use of potential local sources of plastic wastes as secondary raws materials for furniture purposes using 3D printing.

 

The real initial conditions of plastic wastes need to be considered in order to explore a complete closed-loop approach. This could make the notion of secondary raw materials viable, integrated in the plastic strategy of the European Commission for circular economy.

The integration of plastic waste from local sources represent an explorable opportunity, but at the same time, it represents a challenge in terms of identification, variability/heterogeneity and initial conditions of plastic waste to be reused. Moreover, implementation costs of the recycling facilities can be seen a barrier to adoption. Therefore, we will develop a recycling demonstrator system considering the OMDFs ecosystem in the INEDIT framework.

The development of a distributed recycling approach via additive manufacturing (DRAM) and manual injection processes where recycled materials are used in the co-creation phase allows users to conceive customized objects for furniture. In addition, reparability aspects can contribute to a higher customer satisfaction and loyalty and allow for smart maintenance to prolong the lifecycle of products.
