Aim:
Biodegradation of materials, the foot stone of natural regeneration in terms of
sustainable environment, is the breakdown of materials by biological ways. This
is of main importance for handing down the next generations of the quality life
in clean environment, that needs to use the naturally compatible and eco benign
materials. Leather is a bio-based consumer product and it is assumed that it
would correspond to essentialities. However; its grade and impacts are unknown.
The determination of biodegradability of leather material is one of the key
issues having been studied recently in leather industry with respect to
reputation on environmental impact and also new methodologies are being
developed. Method: PrEN ISO 20136 is the recent biodegradablity test based on
the determinaton of CO2 that is the final metabolism product by microbial
activity. In addition to CO2 formation in standart method; the effects of
inhibitive matters in effluent on the alternation of metabolic activity
measured by FDA hydrolysis were ascertained by MetPlate tests. Result: Results
shown that there was an inverse correlation between inhibition rate (%) and FDA
hydrolysis degree. Conclusion: FDA hydrolysis and MetPlate tests are fast,
reliable and alternative test for leather biodegrable tests named for PrEN ISO
20136
