Sustained temperatures of 140 to 160 degrees Fahrenheit for up to two weeks were recorded when coffee grounds were 25% of the material in the compost pile by volume, in informal trials with OSU/Lane County Extension Service. This is often – though not always – achieved with equal volumes of nitrogen-rich green and carbon-rich brown waste. Since coffee is extracted in water, most of the hydrophobic compounds, including oils, lipids, triglycerides, and fatty acids remain in the grounds, as do insoluble carbohydrates like cellulose and various indigestible sugars.
