Sorted, transported and covered: Transforming trash as it travels to its forever home

Think of the last thing you threw away on 澳门六合彩资料鈥檚 campus. Maybe it was a scrap of paper. Maybe it was the remnants of a Prentice wrap. Maybe it was an empty Starbucks cup (OK, it was probably an empty Starbucks cup.) During Recyclemania in 2018, 澳门六合彩资料鈥檚 campus generated more than one million pounds of trash and recycling, which averages out to 31.4 total pounds of trash per person.

Have you ever thought about what happens to your 31.4?

1) Trash on campus

First it ends up in the proper receptacle. Whether that be a trash can on campus or inside a building, all the trash ends up in one of the dumpsters around campus. While dumpsters aren鈥檛 the most glamorous thing in the world, 澳门六合彩资料鈥檚 facilities planning office is working to make the dumpster a form of cutting-edge technology. In the fall of 2017, the office had sensors installed on all the dumpsters, which helped the university not only figure out when a dumpster was emptied, but how full it was.

鈥淚 like having that data for the measurement of the trash and the recycling and how can we increase recycling trash,鈥 said Melanie Knowles, the manager of sustainability. 鈥淭he other practical application of that is, are we getting our dumpsters emptied at the right time?鈥

鈥淲e鈥檝e been able to save some money by saying this dumpster could be emptied twice a week instead of three times a week or this location could use a smaller dumpster, which is less expensive.鈥

Once trash is in the receptacle, it鈥檚 then divided based on type. If it鈥檚 trash, it鈥檚 taken by Republic Services. If it鈥檚 a recyclable, it goes to Portage County Recycling. And if it鈥檚 paper, it鈥檚 taken by River Valley Cardboard.

Dumpsters are emptied on different schedules. Some buildings are emptied six days a week, while some are only emptied once a week.

2) Getting trash to the landfill

Once trash is picked up by Republic, it鈥檚 taken to one of two landfills 澳门六合彩资料 works with, with most trash going to the Countywide Recycling and Disposal Facility in East Sparta, Ohio. Countywide, which opened in 1991, takes in 2,000 tons of trash a day from 26 counties in Ohio.

鈥淚鈥檓 going to say 90% of it comes from Stark, Summit and Tuscarawas Counties,鈥 said Tim Vandersall, the operations manager at Countywide. 鈥淭here鈥檚 a lot of landfills in Ohio and it doesn鈥檛 make sense for trucks to drive hundreds of miles to get to a landfill and pass up five other landfills.鈥

All trucks at Countywide go through the same routine. They first weigh in on the truck scales before telling an attendant what trash they鈥檙e hauling.

Drivers hauling normal trash head to the top of the landfill, while those hauling special waste have to go through a different routine.

鈥淪pecial waste is basically anything other than normal household waste,鈥 Vandersall said. 鈥淪tuff  from an industry or some commercial facilities.

Countywide stretches across 258 acres, with 175 of them already filled with trash. Those 258 acres are divided into 20 different cells for controlled dumping.

鈥淐ells are generally built a year or two in advance, so we build them as we need them,鈥 Vandersall said. 鈥淲e change cells annually or biannually.鈥

3) The life of trash at the landfill

Countywide鈥檚 peak sits 1,250 feet above sea level and requires a drive up a long, winding hill to reach. About halfway up, the ground turns into a substance of half trash, half dirt. The sides of the landfill are draped in protective netting to prevent trash like plastic bags from blowing away. Republic employs three full-time employees and a staff of part-timers to pick up moved trash.  

Trucks dump their trash at the top of the landfill. Countywide has $8 million worth of construction equipment at the top of the landfill that compresses, crushes and moves trash around to make sure every part of the cell is full before Countywide employees begin putting trash in a different cell. Dirt is hauled up the top of the landfill daily to serve as a layer between trash dumps. 

Countywide is a 100% lined landfill, which means it鈥檚 built on a three-foot-deep liner system consisting of recompacted clay, bentonite and plastic to prevent trash from seeping into the ground. This, coupled with a layer of gravel and piping above it, serves as the 鈥渓eachate collection system.鈥 When trash pieces pile up, they form a liquid called leachate that can seep into the ground and poison surrounding earth.

鈥淎s the hundreds of feet of garbage above that decomposes the liquid down to the bottom, it ends up in that gravel pack,鈥 Vandersall said. 鈥淥nce it gets to the low point, we have pumps that constantly pump it off into our storage tanks.鈥

With China enacting it鈥檚 new , it has stopped taking North America鈥檚 trash and recycling. In 2016, the U.S. exported 16 millions tons of waste to China. In addition, China processed , paper and metals. Now all that waste is stuck in the U.S. with nowhere to go.

4) The future of trash

America generated 262.4 million tons of trash in 2015, according to the EPA.  

Knowles said trash can sensors are a step in the right direction for the Office of Sustainability.

鈥淚t鈥檚 valuable to be able to know that what you鈥檙e doing is effective and where we need to focus our efforts,鈥 she said. 鈥淚t鈥檚 valuable to know what the composition of our recycling and waste stream are.鈥

And while Countywide might be a landfill covered in dirt and trash now, that鈥檚 not what it鈥檒l look like forever. The life of the facility is 100 years, meaning once it鈥檚 full of trash, a mixture of clay and soil will be placed on top of the trash on it for grass to grow. While its uneven size means buildings can鈥檛 be put on it, it can still be turned into hiking trails or a park.

 

Regardless of what the world looks like when Countywide closes its gates as a landfill, Vandersall thinks society will have moved past the traditional landfill.

鈥淭echnology is changing so rapidly, and we鈥檙e getting smarter and smarter,鈥 he said. 鈥淚 think we鈥檒l be doing something better with our trash in a hundred years.鈥
