Introduction to Dillo Dirt™

"Dillo Dirt™" is a compost made by the City of Austin since 1989. If you know Austin, you will not be surprised to learn that it was the first program of it's kind in the state and one of the oldest in the nation. All yard trimmings collected curbside across the City as well as some of our treated sewage sludge are combined and composted to create Dillo Dirt™. The heat generated in composting (130 to 170 degrees fahrenheit) is sufficient to virtually eliminate human and plant pathogens. After active composting for over a month, our compost is "cured" for several months, then screened to produce finished Dillo Dirt™.

Dillo Dirt™ easily meets all Texas and EPA requirements for "unrestricted" use, which even includes vegetable gardens, if you desire. Like many other composts, Dillo Dirt™ has many benefits to the soil and plants. Composts add to the organic matter in the soil, reducing watering. Organic matter feeds the microbes in the soil as well as plants, making a more healthy environment. Dillo DirtTM is made from totally recycled materials, and this recycling is less expensive to citizens than landfilling these materials.
