What We Did  We wanted to see how many people would pick up a recyclable at different locations and see if the environment (Valley Square, Montgomery Mall and Meyer Way Park) had any affect on the number of people who picked up the recyclable. We also tested to see if the type of recyclable (water bottle and can) had any affect on whether people were more inclined to pick up the litter.

Procedure  To do this we placed a recyclable near its respected waste bin and watched pedestrians as they walked by and recorded the gender of the person and whether or not they picked up the recyclable  Because of the nature of our data, all of our data was qualitative

History of Recycling  Definition-the processing of used or waste material so that it can be used again, instead of being wasted  Recycling is a key component of modern waste reduction or the Three R’s  “Reduce, Reuse, Recycle”  Recyclable materials include many kinds of glass, paper, metal, plastic, textiles, and electronics  Recycling has been a common practice for most of human history, dating as far back as 400 b.c.

History  Back when new materials were scarce, households had less waste, meaning that they recycled waste as new goods  Recycling is encouraged even more during wartimes when most resources were focused towards the war  First recycling mill in USA was Waste Techniques, built in Conshohocken, Pennsylvania in 1972  FirstEnergy's recycling facility at the Bruce Mansfield Plant in Shippingport, Pennsylvania is the largest in the USA  Philadelphia has been rated as the #1 most recycling city in the nation

Government Involvement  National Government oversees national recycling goals and regulations  More specific regulation and goals come from a state level  Some states ban recyclable goods in landfills  Some even offer rewards for recycling bottled goods at 5 cents a can  American Recycles Day- November 15  Earth Day- April 22

Recycling Stats  251 million – tons of trash in the United States  53.4 – percentage of all paper products recycled in the United States  32.5 – percentage of total waste that is recycled in the United States  100 – approximate percentage of increase in total recycling in the United States during the past decade  8,660 – number of curbside recycling programs in the United States in 2006  8,875 – number of curbside recycling programs in the United States in 2003  95 – percentage of energy saved by recycling an aluminum can, compared with manufacturing a new one  4.6 – pounds of trash per person per day in the United States (most in the world)  1.5 – pounds of recycled materials per person per day in the United States

Conclusion-Type of Recyclable  There is no association between the type of recyclable and picking up a recyclable, according to our research  The type of litter should not impact whether or not it is picked up  The average number of bottles picked up should match the average number of cans picked up

Application  Everyone is encouraged to recycle/ not pollute  There is a lot of pollution/litter  Some people are conscious about this issue  Keep an eye out for litter, pick it up and dispose of it in its correct container

Sources of Bias/Error  People may not have seen the recyclable  People may not know what to do with recyclable  Not enough data  Only surveyed for one day at each place  More “green” people may have stayed home due to the weather/vacation  People may have their hands full  People may think the trash is dirty and not want to get germs

Personal Opinions  We had a lot of data, maybe too much  Tough to keep organized and make sure we watched everyone  Took the entire first day to enter everything into fathom  We had a lot of tests  Having only categorical data limited the number of tests we could use  Less people recycle than we thought
