|World Centric products compost faster in commercial facilities than at home.|
Comparing Rates of Composting
The rates of biodegradation for different compostable products depend on the composition and thickness of the materials used, as well as the conditions of composting. Commercial composting facilities grind the materials, turn over the piles, and produce high temperatures in the piles, thus reducing the amount of time it takes to compost the materials. Home composting rates are slower and vary widely, depending on how frequently the piles are turned over, and on the moisture, material content, and temperature of the piles. As a result, World Centric recommends commercial composting as the best method for disposing of our products.
