The method is simple and i

32、nexpensive, does not require special bioreactors, and is scaled for use in any general-purpose laboratory. It requires the use of a standard and homogeneous synthetic solid waste. The synthetic waste components are dry, clean, safe products which can be stored in the laboratory without any odour or

33、health problems. The synthetic waste is of constant composition and devoid of any undesired plastic material which could be erroneously identified as test material at the end of testing, altering the final evaluation. The bioreactors are small, as is the amount of synthetic waste to be composted (ap

34、proximately 3 l). With the limited amount of test material, this method provides a simplified test procedure. This test method is not aimed at determining the biodegradability of plastic materials under composting conditions. Further testing will be necessary before being able to claim compostabilit

The method is not applicable to the determination of the biodegradabili

36、ty of plastic materials under composting conditions. Further testing is necessary to be able to claim compostability.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

38、 terms and definitions apply.3.1compostorganic soil conditioner obtained by biodegradation of a mixture consisting principally of vegetable residues, occasionally with other organic material and having a limited mineral content3.2compostabilityability of a material to be biodegraded in a composting

39、processNote 1 to entry: To claim compostability, it must have been demonstrated that a material can be biodegraded and disintegrated in a composting system (as can be shown by standard test methods) and completes its biodegradation during the end-use of the compost. The compost must meet the relevan

40、t quality criteria. Quality criteria are, e.g. low regulated metal content, no ecotoxicity, no obviously distinguishable residues.3.3compostingaerobic process designed to produce compost3.4disintegrationphysical breakdown of a material into very small fragments3.5dry massmass of a sample measured af

43、ained from a known volume of test material or compost after incineration at about 550 C from the total dry solids (3.8) content of the same sampleNote 1 to entry: The volatile-solids content is an indication of the amount of organic matter present.4 PrincipleThe method determines the degree of disin

44、tegration of test materials on a laboratory scale under conditions simulating an intensive aerobic composting process. The solid matrix used consists of a synthetic solid waste inoculated with mature compost taken from a municipal or industrial composting plant. Pieces of the plastic test material a

45、re composted with this prepared solid matrix. The degree of disintegration is determined after a composting cycle, by sieving the final matrix through a 2 mm sieve in order to recover the non-disintegrated residues. The reduction in mass of the test sample is considered as disintegrated material and

46、 used to calculate the degree of disintegration.5 Synthetic solid wasteThe composition of the synthetic waste used in this method is described in Table 1.Well aerated compost from a municipal or industrial aerobic composting plant shall be used as the inoculum. The compost inoculum shall be homogene

47、ous and free from large inert objects such as glass, stones, or pieces of metal. Remove any such objects manually and then sieve the compost on a screen of mesh aperture between 0,5 cm and 1 cm. It is recommended that compost from a plant composting the organic fraction of solid municipal waste be u

48、sed in order to ensure sufficient diversity of microorganisms. If such a compost is not available, then compost from plants treating farmyard waste or mixtures of garden waste and solid municipal waste can be used. The compost shall not be older than four months.Prepare the synthetic waste manually by mixing the different components listed in Table 1. The allowed tolerance on the mass measurements of the synthetic waste components, water included, is 5
