Elaeis guineensis standing unplanted in Indonesia, tropical hardwood forests are being cleared for palm oil plantations. Furthermore, as the remaining unprotected lowland forest dwindles, developers are looking to plant peat swamp land, using drainage that begins an oxidation process of the peat which can release 5,000 to 10,000 years worth of stored carbon. Drained peat is also at very high risk of forest fire. There is a clear record of fire being used to clear vegetation for oil palm development in Indonesia, where in recent years drought and man-made clearances have led to massive uncontrolled forest fires, covering parts of Southeast Asia
Rendering (animal products) separates the fat from the water. The solids may be used in food products, pet foods, etc., depending on the original materials. The separated fat may be used in food products, or if in surplus, may be diverted to soap making operations. Most edible rendering is done by meat packing or processing companies. One edible product is greaves, which is the unmeltable residue left after animal fat has been rendered. An alternative process cooks slaughterhouse offal to produce a thick, lumpy "stew" for the pet food industry, which uses it principally in tinned cat and dog foods. Such plants are
