Trash Talk Series from Sustainable Klamath, Solid Waste Action Committee (SWAC)
Renewable Natural Gas (RNG), produced by the natural decomposition of your trash, is providing power to 3,000 homes in the Rogue Valley. In the future, it will also fuel an entire fleet of garbage trucks, and more…
As you may have learned in a previous Trash Talk segment, Klamath County is under a contract with Rogue Disposal and Recycling, which permits Rogue Disposal and Recycling to transport our trash to their Dry Creek Landfill in Jackson County. What you may not know is how Rogue Disposal and Recycling is putting all that waste to use.
Every day, an average of 90 tons of trash is transported from Klamath County to the Dry Creek Landfill in Eagle Point, where Rogue Disposal and Recycling has been working on a closed-loop plan for over a decade.
“Closed-loop” is a term that refers to a system in which a business will reuse the same materials over and over again to create new products. It’s an increasingly popular business model that diverts materials from the landfill and streamlines production. But in this case, where the Dry Creek Landfill is the business and the trash in the landfill is the material, closed-loop refers to the disposal stage being fed back into the creation of a new product. And that new product is fuel.
When organic materials in solid waste decompose, they produce biogas – and that biogas can be used in many ways. Right now, the Dry Creek Landfill Gas-To-Energy Facility captures biogas from the landfill and uses generators to produce 3.2 megawatts of renewable electricity, which Rogue Disposal and Recycling sells to Pacific Corp., ultimately providing power to more than 3,000 homes in the Jackson County area, annually.
In the future, Rogue Disposal and Recycling plans to do even more. They plan to refine their biogas into a high concentration of methane called Renewable Natural Gas (RNG), and eventually fuel their entire fleet of garbage trucks with it.
Currently, the majority of their fleet is fueled by Compressed Natural Gas (CNG), which is derived from fossil fuels. The only difference between CNG and RNG is the source of the gas: CNG comes from fossil fuels extracted from beneath the earth’s surface, whereas RNG comes from the decomposition of organic matter. This means that any vehicle able to run on natural gas can take both CNG and RNG. This also means that, in regard to infrastructure, changes must be made to support CNG (or natural gas in general) before RNG can take over.
By 2023, Rogue Disposal and Recycling projects that they will have achieved a large part of their closed-loop plan by having converted their entire fleet of garbage trucks to CNG. And eventually, they will fuel their natural gas-powered fleet exclusively with the RNG they produce in their own Gas-To-Energy Facility at the Dry Creek Landfill. The infrastructure innovations required to harvest, refine, and use RNG are projected to take about a decade to complete, but some of them can already be seen today. For example: Rogue Clean Fuels, part of the Rogue Waste family of companies, has built a CNG fueling station on Antelope Road that is open to the public, and it is accommodating a growing list of area companies that also use CNG to power their fleet vehicles.
Rogue Disposal and Recycling’s ultimate closed-loop solution stands to reduce greenhouse gas emissions by recycling carbon that is already in the atmosphere; and with its ability to produce more than 2 million diesel-equivalent gallons per year, it also has the potential to fuel other clean-burning facilities and vehicles throughout Southern Oregon.
So, why is this important to us here in Klamath County? After all, Rogue Disposal and Recycling doesn’t pick up our curbside trash – we use Waste Management for that. And our homes are not receiving power from the Dry Creek Landfill Gas-To-Energy Facility.
Knowing that your properly managed trash could legitimately provide power to your home, business, or vehicle in the future, all while helping to keep our air and environment clean for future generations, provide jobs, and replace problems with solutions is a huge deal! Rogue Disposal and Recycling’s mission can serve as a positive example for surrounding communities, like ours.
While we want to recycle as much as we can, we should also remember that even when we can’t recycle something, we can still put it to good use by disposing of it properly. So, be sure to follow our local Waste Management guidelines for recycling, and when in doubt, throw it out.
While you’re following guidelines and discovering the wonderful world of waste management, why not also take a walk once a week and help to beautify our community by picking up litter as you go? Not only will you support your own health with physical activity and build community pride, but by placing litter in appropriate trash cans, you’ll also be helping to make power at the Dry Creek Landfill and you’ll be supporting a future that is filled with positive possibilities for generations to come.
