  Purpose: To explore the perception of unique recycling patterns.

• Question: For example, if you have a mattress or a microwave as waste, where do you take them?
  Purpose: To learn what people do with difficult-to-classify waste.

Additional Information

• Question: What do you think of an identifier of waste that uses your camera to help reduce time in classification?
  Purpose: To gather feedback on a potential feature using Augmented Reality.

• Question: What do you think of crafting items by reusing waste?
  Purpose: To gather feedback on a potential feature involving DIY projects.

Interview Transcript

Context: Image Analysis

Interviewer: Juan Manuel Pérez S Interviewee: Camila Robayo Herrera

• Question: What is happening in the image?
  Response: There is accumulated waste in the street.

• Question: How do you think this happened?
  Response: The bags were not closed correctly, leading to a mass of garbage on the street. Citizens followed the disorder and placed their garbage on top of the mess.

• Question: Why do you think this happened?
  Response: This happened because there is no citizen consciousness about the environment.

• Question: Who do you think is responsible?
  Response: All of us are responsible.

Context: Waste Classification at Home

• Question: What do you do next?
  Response: I ask my mom or search on the internet with my phone.

• Question: How do you search to know the type of waste?
  Response: I use keywords and sometimes search for the name of the product.

• Question: Why do you search where the garbage goes?
  Response: I like to classify waste and also get scolded if I classify it wrong at home.

• Question: Is it easy to find the type of waste on the internet?
  Response: Yes, most of the time it is easy to find the type of waste.

Context: Uncertainty in Waste Classification

• Question: What do you do next?
  Response: I use my common sense and place the garbage where I think it goes.

• Question: How often does this situation happen to you?
  Response: Very few times.

• Question: Why do you think it isn’t very common?
  Response: Because most of the time I rely on my recycling patterns.

• Question: Do you think everyone has the same recycling patterns as you do?
  Response: No, sometimes when I visit friends' houses, they don’t classify waste correctly.

• Question: For example, if you have a mattress or a microwave as waste, where do you take them?
  Response: Normally, we take mattresses to foundations. For microwaves, some shopping malls have designated spaces for this type of waste.

Additional Information

• Question: Based on what you’ve said, what do you think of an identifier of waste that uses your camera to help you reduce time in classification?
  Response: It is interesting because for those cases where it is difficult to know what materials are in my waste, it would help with my investigation.

• Question: What do you think of crafting items by reusing waste?
  Response: I am not the type of person who likes to reuse waste to craft DIY items.
