Data Collection : For all of the literature reviews done by us, the data are collected from quantitative data collection. They used surveys and questionnaires to find out the values and plot graphs to find trends.
Shaquille and Ibrahim's Literature Review: The people who contributed to the questions and information are mostly organisations like zerowastesg and the National Environmental Agency (NEA).
Wun Juan's Literature Review: The people who contributed to the information are mostly volunteers who are willing to voice out their opinions and ideas on how to reduce waste to save the environment on online articles.
