  • Closed loop supply chain network for local and distributed Plastic recycling for 3D printing: a MILP-based optimization approach
    Resources Conservation and Recycling, 2020
    Co-Authors: Pavlo Santander, Hakim Boudaoud, Fabio Cruz Sanchez, Mauricio Camargo
    Abstract:

    Recent research and initiatives increasingly propose a new approach, based on distributed Plastic recycling for open-source (OS) 3D printing technologies, as a way to deal with the issue of Plastic waste and to support the development of the circular economy (CE). Distributed recycling can be thought of as a sort of “smart grid”, composed of small and coordinated recycling units. However, the operational complexity of this distributed approach limits its application. Furthermore, the environmental and economic advantages have yet to be demonstrated. This article therefore explores the economic and environmental feasibility of this distributed Plastic recycling approach from a logistics perspective, as a step towards its validation. To achieve this, an optimization mixed integer linear programming (MILP) model was used as an evaluation tool, representing a local closed loop supply chain (CLSC) network. The proposed model is illustrated using a case study of a university seeking toimplement a distributed recycling demonstrator in order to recover 3D printing wastes from secondary schools in the northeast of France. Following this step, a sensitivity analysis was carried out considering the market variations (price of virgin Plastic Filament) and the amount of available Plastic waste derived from the schools. The results obtained show positive economic and environmental benefits of carrying out this new method of Plastic recycling. This work serves as a basis for continuing to explore the feasibility and replication of the distributed Plastic recycling network in other contexts.

  • Tightening the loop on the circular economy: Coupled distributed recycling and manufacturing with recyclebot and RepRap 3-D printing
    Resources Conservation and Recycling, 2018
    Co-Authors: Shan Zhong, Joshua M Pearce
    Abstract:

    A promising method of enhancing the circular economy is distributed Plastic recycling. In this study Plastic waste is upcycled into 3-D printing Filament with a recyclebot, which is an open source waste Plastic extruder. The recyclebot is combined with an open source self-replicating rapid prototyper (RepRap) 3-D printer, to enable post-consumer ABS Plastic Filament from computer waste to be further upcycled into valuable consumer products pre-designed in the digital commons. The total electrical energy consumption for the combined process is monitored and an economic evaluation is completed. The coupled distributed recycling and manufacturing method for complex products reduces embodied energy by half, while reducing the cost of consumer products to pennies. This economic benefit provides an incentive for consumers to both home recycle and home manufacture, which tightens the loop on the circular economy by eliminating waste associated from transportation and retail. It is clear from the results that waste Plastic can be significantly upcycled at the individual level using this commons-based approach. This tightening of the loop of the circular economy benefits the environment and sustainability as well as the economic stability of consumers/prosumers.
