The work of preparing International Standards is normally carried out through ISO
16、 technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates cl

In particular the different approval criteria
18、 needed for the different types of ISO documents should be noted.

ISO 2016 All rights reserved vBS ISO 14853:2016ISO 14853:2016(E)IntroductionWith the increasing use of plastics, their recovery and disposal have become a major issue. As a first priority, recovery
23、 should be promoted. For example, plastic litter, which originates mainly from consumers, is difficult to recover completely. Additional examples of materials difficult to recover are found in the disposal of fishing tackle, agricultural mulch films and water-soluble polymers. These plastic material
24、s tend to leak from closed waste management infrastructures into natural environments. Biodegradable plastics are now emerging as one of the available options to solve such environmental issues. Plastic materials, such as products or packaging, which are sent to anaerobic treatment facilities should
