BS EN 17417 specifies a method for the determination of the ultimate anoxic biodegradation of
plastics made of organic compounds, where the amount of the produced nitrogen and carbon dioxide at the end of the test is measured.
BS EN 17417 helps you test the biodegradation of plastic and improve water quality.
BS EN 17417 on the determination of the ultimate biodegradation of plastics materials is useful for:
The biodegradation of a chemical substance strongly depends on environmental conditions. The presence or the absence of oxygen is significant for the metabolic pathway on which the degradation by bacteria can take place. Denitrification can take place in both terrestrial and marine ecosystems. Typically, denitrification occurs in anoxic environments, where the concentration of dissolved and freely available oxygen is depleted.
BS EN 17417 determines the ultimate biodegradation of plastic materials in an aqueous system under anoxic (denitrifying) conditions by measurement of pressure increase.
BS EN 17417 provides you guidance for equipment and materials, the test preparation, calculation, and evaluation of the test. This will help you carry out the test accurately.
BS EN 17417 specifies that the biodegradable polymers that are soluble in water could be added systematically and continuously to the denitrification unit as a solid substrate, as long as the biodegradable polymers are present in a solid substance, it shall be ensured that they remain in the denitrification tank in order to prevent operational failure during other phases of the wastewater treatment plant. BS EN 17417 ensure that the water quality remains good and plastic particles are not present in the water.
