− | <p>Ms. Reynolds talked to us about the level of recycling at Rose-Hulman and the variety of initiatives taken over the past 22 years. Initially, the campus had several home-sized recycling bins at the back of one building and only took PET plastic, paper, cardboard, tin, aluminum, and E-scraps. The paper and cardboard were sold, while the other recycled products were sent to Indiana State University’s recycling facilities. The demand grew enough for Rose-Hulman to develop the current center with 3 compactors and multiple recycling drop offs per week. Currently, Rose has received grants and works with Republic recycling company to manage the recycling. A report she gave us indicated a total of 48 tons of cardboard, 6 tons of paper, and 27 tons of scrap metal recycled in 2015. While impressive, Rose can still improve as there was still over 400 tons of trash generated that year, which was equivalent to 2552 cubic yards. She has been very receptive to the student driven initiatives to improve better signage and convenience.</p> | + | <p>Ms. Reynolds talked to us about the level of recycling at Rose-Hulman and the variety of initiatives taken over the past 22 years.

Understanding what Rose’s campus has done to help the plastic waste build up and their initiatives has helped us target our implementation methods and has informed the background of our project. </p> |

+ | <p> Method 1 directly addresses the issue of plastic waste in the ocean, because it involves deploying small vessels to follow the ocean currents and filter the surface water for floating plastic and microplastics. The sea water would filter through the base of the vessel through a screen infused with the PEBBLE bacteria. Any plastics would be caught on the mesh and be degraded by the bacteria. The mesh would also theoretically collect and store the terephthalic acid byproduct until the vessel is picked up for maintenance. The collected acid would then be removed and shipped to the industries that need it, while the vessel culture would be diluted and sent back out. This method would need government-level support and would also be a standardized collection method for TPA.</p> | ||

+ | <p>Method 2 institutionalizes bioreactor tanks of the modified E.coli at major waste and recycling collection facilities. The bacteria in the reactors would filter out the PET plastic and breakdown the polymer into terephthalic acid and ethylene glycol, a carbon source for the cells’ metabolisms. The acid would be syphoned off and sent to plastic industries to be used in the creation of additional plastics. The material not degraded would be sanitized and moved on to the next stages in the waste disposal process. This method would be a community and local government/business commitment and would address the waste generated on land. </p> | ||

+ | <p>To make an impact on the individual-level, we came up with Method 3 where home kits would degrade the PET plastic before it was sent to collection facilities. These kits would be equipped with a receptacle for the bacteria to be housed, and the plastic would be fed through a system which prevented the user from coming in contact with the bacteria. The terephthalic acid would be syphoned off and the user could bring it to a collection facility for the plastic industry and potentially receive monetary compensation. This reward would act as an incentive for users to put the plastics in the compost kit. The material not degraded could then be sanitiatized, packaged, and taken to the local recycling or waste collection facilities. Method 3 addresses the source of the waste generation at the very beginning of the process and provides an incentive for people to recycle. </p> | ||

+ | <p> Having designed three methods from our own backgrounds, we wanted to reach out to the community to gauge their receptiveness to each method and understand their concerns about the growing plastic waste. In the survey, we present the three possible implementation methods of our project and ask about the public's concerns with each of our methods. We reached out to experts and willing volunteers for help with the design and piloting of the survey. We ask the final career question to gather an idea about the relative age groups of our populations. </p> | ||
