Composting is a natural process by which organic material is decomposed into humus.
Organisms that decompose organic matter use carbon as a source of energy and nitrogen for building cell structures One common mechanism is hydrolysis, in which random non-enzymatic chain scission of ester groups leads to reduction in molecular weight

The corroboration of decomposition in laboratory conditions according to current standards answers only the question whether the plastic wrapping material is biologically degradable.
The experimental samples were placed in the compost pile operated by the Central Composting Plant in Brno and were checked and visually assessed during the experiment which lasted 13 weeks (standards for the laboratory test required 12 weeks).
All existing norms related to this issue describe tests in laboratory conditions. Research in real conditions is not supported by norms neither exist methodologies describing procedures for the research of the decomposition of these materials in real conditions
no laboratory tests were capable of copying the conditions of industrial composting plants.
