Compound natural annual growth rate

World consumption of polylactic acid biodegradable polymers has increased significantly over the last five years as major suppliers such as Nature Works have brought their 140,000 tonnes per annum plant fully on stream. In 2005, world consumption of PLA amounted to 35,800 tonnes against 8,700 tonnes five years earlier. During the period 2005-2010, PLA consumption is forecast to reach 89,500 tonnes, which represents a compound annual growth rate of 20.1%. 

Aquaculture is an expanding sector, with an annual growth rate of around 8-10 % in terms of world tonnage It already supplies more than 25% of all aquatic products. Numerous forms of aquaculture coexist While carp (70 % of fresh water aquaculture) and prawns (a brackish water production) are both firmed in ponds where natural feeding is still dominant, the production of salmonids and other marine fish is based exclusively on the use of compound feeds.
