Over the past three days of classes, I have been immersed into the world of Green Supply Chain Management. I have learned about the concept of “greening” and the ways in which organizations can make their supply chains more environmentally friendly and sustainable. I was also introduced to the Cradle-to-Grave and Cradle-to-Cradle approaches and learned how they differ on the topic of waste. I found the idea of industrial symbiosis to be both an interesting and effective way of managing and repurposing waste. I also like the connection between eco-design/design for the environment and design-for-manufacturability because the design phase gives the most opportunity to act in a proactive, rather than reactive, capacity in regards to creating sustainable and environmentally sound products. Additionally, I feel that I now have a better understanding of reverse logistics, the vital component of a sustainable supply chain, and the differences between a linear and circular supply chain. It is now apparent to me that any organization looking to embrace Green Supply Chain Management must modify its existing traditional supply chain networks to reflect a closed-loop supply chain that allows for the introduction of reverse flows. On the topic of reverse logistics, it was interesting to hear about the new 3 Rs and how they expand upon the traditional 3 Rs. I was also curious about the fact that the textbook mentioned “every reverse logistics system should include gatekeeping, collection, and sortation” because I had never read this before so I’m interested to explore more about these apparently imperative concepts. Furthermore, when I read about the main problems with reverse logistics, I was pleasantly surprised to see that they were all easy to comprehend and they prompted me to deeply think about the ways in which they could be addressed and managed. I had also never before considered the different types of reverse logistics networks that retailers might employ. However, upon learning about the aforementioned, I thought that the third-party returns management RL network and return to suppliers RL network were interesting RL retailer networks because they limit the reverse logistics responsibilities of the organization in question and instead redirect it to other parties. I think this is a really good idea because in doing so, it seems that the reverse flows will be better handled and more effectively managed compared to a situation in which the organization producing the goods has to manage both the forward and reverse flows.
