Coffee production in Indonesia in the classic Indonesian cup profile. Larger processing mills, estates and some farmers' cooperatives on Sumatra, Java, Sulawesi and Bali produce "fully washed" coffee. The most unusual form of coffee processing in Indonesia is "Kopi Luwak". This coffee is processed by the Asian palm civet ("Paradoxurus hermaphroditus"). The animals eat ripe coffee cherries and their digestive process removes the outer layers of the fruit. The remaining coffee beans are collected and washed. Coffee experts believe that the unique flavour of Kopi Luwak comes, at least in part, from the extraction of naturally occurring potassium salts from the beans during the
Metabolic waste excreta. Some mammals including humans excrete uric acid as a component of their urine but it is only a small amount. These compounds form during the catabolism of carbohydrates and lipids in condensation reactions, and in some other metabolic reactions of the amino acids. Oxygen is produced by plants and some bacteria in photosynthesis, while CO is a waste product of all animals and plants. Nitrogen gases are produced by denitrifying bacteria and as a waste product, and bacteria for decaying yield ammonia, as do most invertebrates and vertebrates. Water is the only liquid waste from animals and photosynthesizing plants.
