ISO 14855 PDF

Testing for biodegradability means going through a series of test methods to ensure a product will biodegrade at the end of its life and under certain circumstances. One internationally accepted method used for this is the BS EN ISO ; Determination of the ultimate aerobic biodegradability of plastic materials under controlled composting conditions — Method by analysis of evolved carbon dioxide. The main test method for this in the standard BS EN ISO using a system based on mature compost as the solid bed, which provides nutrients and an inoculum this refers to our compost. The inoculum is formed of many substances, such as trees, leaves, food waste, etc.

ISO 14855-1:2005

ISO specifies a method for the determination of the ultimate aerobic biodegradability of plastics, based on organic compounds, under controlled composting conditions by measurement of the amount of carbon dioxide evolved and the degree of disintegration of the plastic at the end of the test. This method is designed to simulate typical aerobic composting conditions for the organic fraction of solid mixed municipal waste. The test material is exposed to an inoculum which is derived from compost. The composting takes place in an environment wherein temperature, aeration and humidity are closely monitored and controlled. The test method is designed to yield the percentage conversion of the carbon in the test material to evolved carbon dioxide as well as the rate of conversion. Also specified is a variant of the method, using a mineral bed vermiculite inoculated with thermophilic microorganisms obtained from compost with a specific activation phase, instead of mature compost. This variant is designed to yield the percentage of carbon in the test substance converted to carbon dioxide and the rate of conversion.
