About Us

Atlas Organics is a composting company headquartered in Spartanburg, South Carolina. We are dedicated to providing the highest quality finished compost to residential homes, corporations, local businesses, and municipalities throughout the country.

Atlas Organics exists because we believe that people can and should contribute to something greater than themselves. Our goal is to become the greatest organics recycling service in the world through providing access to composting for more homes, companies, and municipalities than ever before!

2015 was the start

In 2015, our founders, Gary Nihart Jr. and Joseph McMillin formed Atlas Organics to develop a company that provides access to composting to homes, companies and municipalities through a comprehensive organics recycling platform that includes collection, processing and consulting services.

Atlas Organics is now an award-winning company in the industry that employs more than 135 professionals to serve 1600+ homes, 150+ businesses, 7 municipalities, and sells products to more than 300 organizations. Atlas Organics is a growing company that is reducing methane emissions and landfill waste while improving soil and the environment.

Since early 2022, Atlas Organics has been a part of a greater company- Generate Upcycle, the waste-to-value platform of Generate Capital, PBC. This has been a big step forward in seeing the Atlas mission fulfilled in a more significant way. As a company, we have committed to becoming the global leader in circular waste solutions.

Our Process

Atlas Organics manages and processes a variety of organic waste products including yard waste, food waste, and biosolids at various facilities. Our typical process begins with the acceptance and grinding of yard waste utilizing  horizontal grinders fed by excavators. These machines take loose unground municipally collected yard waste and reduce it in size to create single ground mulch. This material acts as a carbon source in the composting process. After the yard waste is processed, it is either added directly to the composting process or mixed with a nitrogen source such as food waste or biosolids at a ratio of approximately 50:50 by weight. This material is then added to the composting system made up of aeration blowers timers and temperature probes. All material movement on site is done through the utilization of wheel loaders.

What is EASP?

Atlas Organics utilizes Extended Aerated Static Pile (EASP) composting systems originally engineered by O2 Compost. With EASP composting, fresh air (with oxygen) is blown into the pile under positive pressure to maintain aerobic conditions throughout the pile, eliminate the need for pile turning, accelerate the decomposition of the organic waste material, achieve pathogen reduction requirements, and prevent generation of offensive odors. Compared to typical windrow composting operations, Atlas avoids using a diesel-powered windrow turner and avoids generating dust by avoiding pile turning, all while keeping optimal operating composting conditions to process material faster. Throughout the process the material is monitored using various quality control methods including batch protocol, bulk density, moisture, temperature, and Solvita.
Once the material is fully composted, it is removed from the composting system and screened utilizing a Powerscreen Phoenix 2100 trommel screen. This material is then tested by Soil Control Laboratories for nutrients, pathogens, metals, and other horticultural parameters using the US Composting Council Seal of Testing Approval (STA) program. After results are analyzed to confirm regulatory limits are met, the material is sold into the marketplace.
