Plastics — Organic recycling — Specifications for compostable plastics

WARNING — Sewage, activated sludge, soil and compost might contain potentially pathogenic organisms. Therefore, appropriate precautions should be taken when handling them. Toxic test, compounds and those whose properties are unknown should be handled with care.

1 Scope

This document specifies procedures and requirements for plastics, and products made from plastics, that are suitable for recovery through organic recycling. The four following aspects are addressed:

a) disintegration during composting;

b) ultimate aerobic biodegradation;

c) no adverse effects of compost on terrestrial organisms;

d) control of constituents.

These four aspects are suitable to assess the effects on the industrial composting process.

This document is intended to be used as the basis for systems of labelling and claims for compostable plastics materials and products.

This document does not provide information on requirements for the biodegradability of plastics which end up in the environment as litter. It is also not applicable to biological treatment undertaken in small installations by householders.

NOTE 1 The recovery of compostable plastics through composting can be carried out under the conditions found in well-managed industrial composting processes, where the temperature, water content, aerobic conditions, carbon/nitrogen ratio and processing conditions are optimized. Such conditions are generally obtained in industrial and municipal composting plants. Under these conditions, compostable plastics disintegrate and biodegrade at rates comparable to yard trimmings, kraft paper bags and food scraps.

NOTE 2 “Compostable” or “compostable in municipal and industrial composting facilities” are expressions considered to be equivalent to organically recyclable for the purposes of this document.

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

[SOURCE: ISO 472:2013, 2.1735]

3.2

compostable plastic

plastic that undergoes degradation by biological processes during composting to yield CO , water, 2

inorganic compounds and biomass at a rate consistent with other known compostable materials and leave no visible, distinguishable or toxic residue

Note 1 to entry: "Hazardous" is used synonymously to "toxic".

3.3

composting

aerobic process designed to produce compost starting from biodegradable waste

Note 1 to entry: Composting is classified into industrial composting, home composting and worm composting.

3.4

disintegration

physical breakdown of a material into very small fragments
