Passive income: NO

Earning passive income solely from sustainable packaging design and supply chain optimization as a side hustle is challenging. While it is possible to set up systems like automated ordering processes or outsourcing certain tasks to make it more passive, achieving true passive income is rare. Most individuals in this field find that ongoing client communication, project management, and design iterations require active involvement. Setting up such systems can range from $500 to $2000 initially. In terms of reaching a fully passive income level, only a few outliers manage to do so, typically after several years of building a client base and refining processes. It is more common for this hustle to remain semi-passive, requiring periodic input. Misleading expectations often revolve around the idea of quick and effortless passive income. Realistically, passive income in sustainable packaging design and supply chain optimization is more achievable for those willing to put in consistent effort and time. It may not be fully passive for most individuals due to the nature of client projects and the need for ongoing innovation and customer engagement.
