From blog post A, I used waste audit as one of data collected method to research organic waste. My daily waste audit was conducted roughly, but it still brought about my waste stream and the thing that I should consider about to solve problem from the waste as a designer. This means that waste audit is essential first step to investigate organic waste; therefore, many organizations and institutions conducted waste audit to investigate organic waste properly.
This is one of examples that use waste audit as data method. The members of the Green team and other volunteers at WPI sorted the waste into proper bins from six buildings on campus in 2012, America Recycles Day. They divided into ten categories and compile statistics like the ‘food’ waste chart. They drew appropriate recommendations to current waste management through the waste audit. Besides, Bourke (2012) reported that they conducted the waste audit in 2011, and also planned to do waste audit in 2013. Thus, conducting the waste audit in each year provides them with the improvements that compare to old waste audit result and better suggestions for waste management.
Experiment / Study
US EPA (United States Environmental Protection Agency) generated the plans for food waste based on their study. According to EPA,
Anaerobic digestion of food waste has approximately three times the methane production potential by volume than municipal wastewater solids. The study found that the methane production potential of biosolids was 120 m3 gas/ton and food waste around 367 m3 gas/ton. Additionally, anaerobically digesting 100 tons of food waste per day, five days a week, provides sufficient power for approximately 1,000 homes (2016, para5).
They not only proved that food waste becomes a valuable energy, also proposed appropriate management using the key finding of a study. What is more, they added the chart supports their study and organic waste management.
This is the supporting chart demonstrates using food waste for the management is more effective way. As you can see their process, we can find that EPA generates from the food waste problem to reasonable organic waste management. I believe that the way that EPA uses data methods to investigate organic waste is wiser for people and planet.
