Composting of plastics

Biodegradable plastic products must meet stringent quality criteria if they are to be composted. Dedicated standards and certification schemes/tests have been established for verifying the compostability of plastic products. [Pg.33]

Nevertheless, field trials in natural environments are still used to extrapolate results acquired in laboratory tests to biodegradation behaviour under realistic outdoor conditions " Recent German regulations for the assessment of compostability of plastics even impose exposure of the product to a full scale industrial composting process to ensure that total disintegration will occur in real-life waste-processing". ... [Pg.278]

It should be pointed out here that ISO recently modified the standard on the compostability of plastics (ISO 17088) to take this issue into consideration. The current ISO specification requires that constituents present in the plastic formulation in a concentration below 10% shall be tested individually for biodegradation. This is to make sure that minor constituents are also biodegradable. [Pg.69]

The German standard DIN V 54900 (1-5) for testing the compostability of plastics was replaced by the European standard DIN EN 13432. However, It represents an important source for other standards in this field that are partially based on it and therefore it will be described in more detail. ASTM D 7081 consists of five parts and describes the individual tests/procedures and the related evaluation criteria in great detail. [Pg.225]

The European standard DIN EN 14995 also provides a framework for procedures that can be used to support requirements regarding the compostability of plastics. Unlike DIN EN 13432 it does not focus solely on packaging, but defines requirements for plastic materials in general in order to be classified as organically recyclable. [Pg.226]

At the start in 1997 the system was based on the DIN V 54900 [4] prenorm on compostability of plastics. In addition to the norm a certification scheme was published in which some further (technical) rules for certification were specified. These can considered to be a kind of by-law. At the third revision of this certification scheme published in July 2001 [14], the EN13432 [5] and ASTM D6400-99 [54] norms are also mentioned besides the DIN V 54900 as standards along which the compostability can be evaluated. On a few matters of conflict, e.g., heavy metals and test duration of radiolabelled biodegradation tests, the scheme is giving the ultimate guideline for the certification to follow. [Pg.170]

It was recognised by the EU in the 1980s that composting of plastics is a valuable alternative to mechanical recycling [9] and the following variation on D5338-98 has been proposed by CEN TC 261 and accepted by the EU ComnGdssion. [Pg.469]

Standards are essential to ensure the environmental safety of compost. Hydrocarbon plastics do not biodegrade rapidly in compost or in soil and it must be demonstrated that, like of nature s wastes, they do not accumulate in the soil. Standards for biodegradability and compostability of plastics must therefore address, not only the question of non-accumulation of any long-lasting plastics residues in the soil substances but also the safety of any non-degradable residues. These aspects will be discussed in the light of recent scientific studies. [Pg.221]
