The value of a material and resource varies greatly across contexts. What is saved around you, and through what means? Pushed/pulled carts do a lot of the heavy lifting in metropolitan Chongqing for most materials except plastic beverage bottles, which most often fall within the domain of a person carrying a bag. Consider how this cart of to-be-repurposed/recycled material influences the perspectives of those around it and what they consider "valuable" - waste as just something in the incorrect place/hands.
Consider this momentary snapshot in terms of the larger process, and what had to be noticed/reported (and by/to whom) before this new trashcan is placed.
Consider why trashcans are equipped for battery disposal in a given context. These sorts of trashcans are sprinkled (seemingly) randomly throughout Chongqing - certain public squares, the airport, etc. Is this calculated inconsisntency, or are certain contexts more recognized users of disposable batteries than others.
While a clever way of storing bottles on the parts of the students to turn in for money later, there is also latent/underutilized information sitting here for local convenience store owners, restaurants (on a micro level), and beverage companies (on a macro level) to take advantage of. The beverage preferences of students who practice this method of saving bottles are on display for all to see. All one needs to pick out a given bottle is its distinctive cap and/or bottom of the container so that it may be more easily identified from the viewed angle.
This 61 year old man collects plastic packaging cord from various stores near his home outside of downtown Yangon during the week. After having filled several bags, he rides a Hilux truck-ferry ("linecar") into downtown to walk around the largest market (Thein Gyi Market), selling the packaging cord to various merchants. He charges ten kyat per length of cord (850 kyat equal one US $). He says he used to make the trip more often, but that since he has gotten older, work has become more challenging and he has had to rely more upon his grown children to support him.
