Introduction
The method does not require special bioreactors and it is well suited to be run at laboratory scale in any
general purpose laboratory. It requires the use of a standard, homogeneous synthetic waste. The synthetic
waste components are dry, clean, safe products which can be stored in the laboratory without any problem
neither of smell nor of health. The synthetic waste is of constant composition and devoid of any undesired
packaging material, which could be erroneously identified as test material at the end of testing, altering the
final evaluation. The bioreactors are small, the amount of synthetic waste to be composted is also very small
(about 3 L) and, likewise, the amount of test material’s specimens is very limited, with an overall simplification
of the test procedures. The test method is not aimed at determining the biodegradability of packaging
materials under composting conditions and does not cover environmental safety and ecotoxicity issues.
Further testing is necessary for claiming compostability.

1 Scope
This laboratory scale test method using synthetic waste aims at simulating the environmental conditions found
in industrial composting plants. Packaging materials exposed to this environment can be preliminary assessed
for disintegrability. A negative result does not necessarily mean that the test material is not disintegrating
under industrial composting conditions. This test does not replace the acceptance disintegration test as
specified in EN 14045, in accordance with EN 13432.

The following referenced documents are indispensable for the application of this European Standard. For
dated references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.

3 Terms and definitions
For the purposes of this European Standard, the terms and definitions given in EN 13193:2000 and the
following apply.
3.1
compost
organic soil conditioner obtained by biodegradation of a mixture consisting principally of vegetable residues,
occasionally with other organic material and having a limited mineral content
3.2
compostability
potential of a material to be biodegraded in a composting process
3.3
composting
aerobic process designed to produce compost
3.4
disintegration
physical falling apart of a material into very small fragments
3.5
dry mass
mass of a sample measured after drying. It is expressed as a percentage of the mass of the wet sample
3.6
total dry solids
amount of solids obtained by taking a known amount of test material or compost and drying at about 105 °C to
constant weight.
3.7
volatile solids
amount of solids obtained by subtracting the residue of a known amount of test material or compost after
incineration at about (550 ± 10) °C from the total dry solids content of the same sample
NOTE The volatile-solids content is representative for the amount of organic matter present.

4 Principle
The test method evaluates the degree of disintegration of test materials at laboratory scale under conditions
similar to an intensive aerobic composting process. The solid matrix used consists of a synthetic solid waste
inoculated with compost derived from a composting plant. Specimens of the test material are co-composted
with the synthetic solid waste. 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 not disintegrated residues of test material. The
missing mass of the test material is considered as disintegrated and used to calculate the degree of
disintegration.
5 Synthetic solid waste
A synthetic waste, whose composition is described in Table 1, is needed in order to perform the test.
Table 1 — Composition of synthetic solid waste
Material dry mass %
Sawdust 40
rabbit-feed 30
compost 10
starch 10
saccharose 4
cornseed oil 4
urea 2
Total 100
Sawdust of untreated wood shall be used. The sawdust shall be sieved with a 5 mm sieve before application.
NOTE Wood from deciduous trees should preferably be used.
The rabbit-feed shall be a commercial product based on alfalfa (Medicago sativa) and vegetable-meals. If a
product with a different composition is used, it shall be mentioned in the test report. The protein content of the
rabbit-feed shall be of about 15 % and the cellulose content of about 20 %.
Well aerated compost from a properly operating aerobic composting plant should be used as the inoculum.
The compost inoculum should be homogeneous and free from large inert objects such as among others glass,
stones or pieces of metal. Remove them manually and then sieve the compost on a screen of about 0,5 cm –
1 cm. It is recommended that compost from a plant composting the organic fraction of solid municipal waste is
used in order to ensure sufficient diversity of micro-organisms. If such a compost is not available, compost
from plants treating of farmyard waste or mixtures of garden waste and solid municipal solid waste may be
used. The compost shall not be older than 4 months.

EN 14806:2005 (E)
Synthetic waste is manually prepared by mixing the different components listed in Table 1. The allowed
tolerance on the mass measurements of the synthetic waste components, water included, is of 5 %. Water is
then added to the mixture to adjust its final water content to about 55 % by weight in total. This operation
should be performed before start-up. The synthetic waste shall have a carbon:nitrogen (C/N) ratio preferably
comprised between 20-30. The urea concentration can be changed to adjust the C/N value to the prefixed
range. In this case the concentration of the other components shall be proportionally adjusted in order to bring
the total sum to 100.
6 Composting reactor
The composting reactor is a box made with a suitable inert material which does not affect the composting
process, having preferably the following dimensions: 30 cm × 20 cm × 10 cm (l, w, h). In the series the
container chosen shall not vary more than 5 % in dimensions. The box shall be provided with a lid assuring a
tight closing to avoid an excessive evaporation. Additionally the closing between box and lid may be sealed
with an adhesive tape. In the middle of the two 20 cm wide sides, a hole of 5 mm in diameter shall be applied
at a height of about 6,5 cm from the bottom. The two holes provide gas exchange between the inner
atmosphere and the outside environment.
NOTE Attention should be paid not to cover the holes with the adhesive tape, or in any other way.
Other containers with a volume between 5 L and 20 L may also be used, provided that it is preliminary verified
that unfavourable anaerobic conditions are not produced. The container should be closed in a way to avoid
excessive drying out of the content. At the same time openings shall be provided in order to enable gas
exchange and ensure aerobic conditions throughout the composting phase.
7 Procedure
7.1 Sample preparation
The test material shall be cut in order to get specimens with the fixed dimensions defined in Table 2, based on
the test material’s thickness.
The mass of the specimens is determined in material dried to constant mass. The drying technique used at
this stage shall also be used at the end of the test for assessing the final mass of specimens (see 10.2).
Table 2 — Dimension of the specimens to be used in the disintegration test
Thickness of the test material Dimension of specimens
mm mm
≤ 5 25 × 25 × original thickness
> 5 15 × 15 × thickness ≤ 15
7.2 Start-up of the test
At least two reactors are prepared for each test material. The specimen of the test materials are mixed with
1 Kg of wet synthetic waste. The mass of the specimens shall comprise between 5 g and 20 g per rea
