If you dont have a job then go for it man, look at the designation its assistant project operations. Forget about solid waste, at the end you are managing operations of a project, that project could be anything. Meanwhile, if you like the field, you can switch to a decent project management company later, if you dont you can try exploring other fields. Never say no to a new experience.
If you dont know what you like at this stage (most likely), its perfectly normal. You only know after getting your hand dirty in different fields. So explore, explore and explore until you know what you gonna do next. And even other fields which you did not like, will help you to decide what you like or not.
