Landfill Secrets Revealed: From Trash to Treasure at Cincinnati's Mount Rumpke

Building the Perfect Hole

It all begins with digging a massive hole in the ground. But this isn’t just any hole; it’s a meticulously engineered marvel. At the very bottom, we encounter the groundwater layer, which we need to protect. Above this is the subsurface layer—mostly soil, sand, and clay. Once the hole is prepped, we lay down a four-foot-thick layer of clay. Why clay, you ask? Because it’s excellent at preventing liquids from seeping through. It’s like the crust of our landfill sandwich, keeping everything inside nice and tidy.

The Flexible Membrane Liner: Our Hero

Next up is the flexible membrane liner—a super-strong plastic layer that ensures nothing nasty leaks out. This liner, combined with a geotextile layer, acts as the ultimate guardian, filtering and securing all the waste materials.

Leachate Collection: Managing the “Garbage Juice”

Ever heard of garbage juice?

It’s officially known as leachate, and it forms when liquids mix with the trash. To handle this, we use a network of pipes surrounded by gravel, cleverly designed to collect and transport leachate to a treatment facility. This system ensures that harmful substances don’t contaminate our environment.

The Drainage Layer: Keeping Things Flowing

Above the leachate pipes, we add a drainage layer made of shredded tires. This layer stops solid waste from clogging the pipes, allowing liquids to flow freely to the collection system.

Piling Up the Trash

Now, let’s add the main ingredient: your junk! Trash is layered into the cell, and each layer is compacted to save space. At the end of each day, a daily cover—either dirt or a spray-on substance—is added to keep the trash secure and reduce odors.

Capturing Landfill Gas: Turning Trash into Treasure

As trash decomposes, it produces landfill gas, mainly methane—a potent greenhouse gas. To manage this, we install gas collection pipes throughout the landfill. These pipes gather the gas and transport it to a flare system, where it’s burned off or converted into energy. Imagine turning your old sofa into electricity—how cool is that?

Spotlight on Rumpke Sanitary Landfill

Speaking of cool, let’s shine a spotlight on our local gem, the Rumpke Sanitary Landfill, affectionately known as “Mount Rumpke.” Located in Colerain Township, just north of Cincinnati, this landfill is one of the largest in the United States, covering over 230 acres and receiving about 2 million tons of waste annually (Wikipedia) (Wastebits).

Rumpke isn’t just any landfill; it’s an advanced facility that includes state-of-the-art systems for methane gas recovery. The landfill converts this gas into natural gas, which is then used to power homes and businesses. So, not only is your junk being safely stored, but it’s also being transformed into energy that helps power our community (Wastebits).

Closing the Cell: The Grand Finale

When a cell is full, it’s time to seal the deal. We wrap the top with more of that trusty flexible membrane liner and add another thick clay layer. This final cover is topped with soil and planted with grass, transforming the landfill into a green hill.

Even after closure, the cell remains active behind the scenes, with systems continuously monitoring and collecting gas and leachate. It’s like a well-oiled machine, ensuring everything stays in check for years to come.
