What is Earth Engine?

Earth Engine is a next-generation composting system that delivers high-quality, contaminant-free soil products. Using advanced technology and a science-based approach, Earth Engine creates compost that is free from plastics, glass, weed seeds, and harmful pathogens – making it one of the cleanest, most reliable options on the market.
The process combines carbon-rich mulching materials and cattle manure sourced from stock yards and processing facilities – not landfill. These inputs are composted in controlled conditions using custom-built aeration equipment and remote thermal monitoring to maintain ideal temperatures. The result is a matured, nutrient-rich compost that smells earthy, is easy to handle, and ready to enhance your soil.

How Earth Engine Works The 3-Step Process

Step 1.

Clean, Purposeful Inputs

Unlike many compost products on the market, Earth Engine does not rely on landfill waste. Instead, it blends carbon from mulching companies with clean cattle manure, setting the foundation for a high-quality product from the start.

Step 2.

Thermophilic Composting

The compost undergoes a carefully managed thermophilic stage, where it reaches high temperatures that eliminate weed seeds, pathogens, and disease spores. This stage is remotely monitored using thermal probes to ensure accurate timing for turning and aeration. This process takes 3 to 6 months to complete, ensuring thorough maturation and microbial richness.

Step 3.

Screened, Matured End Product

After the compost matures, it is screened to remove any clumps, resulting in a soft, rich, and earthy-smelling product that is ready for immediate use. It is stable, won’t reheat, and won’t break down further. A properly matured compost smells like clean, living earth – never unpleasant.
