How do I get a degradability report for materials

Bykeyfulgroup

As we all know, to prove that a material is biodegradable, we need to do biodegradation test report.

However, what kind of qualified laboratory can make this report?

What are the test methods?

What items will be tested ?

These are of great interest to you, as follows to introduce in detail

1. Biodegradable laboratory accreditation

  • DIN CERTCO
  • BPI
  • ABA
  • JBPA
  • CNA
  • CMA

2.Test methods for biodegradable products

  • 2.1 Industrial compost
    • DIN EN 14995:2007
    • DIN EN 13432:2000
    • ISO 17088-2012
    • ISO 18606-2013
    • ASTM D6400-19
    • ASTM D6868-19
    • S 4736-2006
  • 2.2 Home OK compost
    • AS 5810-2010
    • NF T51- 800:2015

3.Test items of composting tests

  • 3.1 Biodegradation test
    • Requirement：Absolute or relative biodegradation rate at least 90%
  • 3.2 Disintegration test

Requirement：No visible and distinguishable sample residues ; no more than 10 % of original dry weight remains after sieving on a 2.0-mm sieve

3.3 Safety test

  • 3.3.1  Hazardous Substances test
    • The hazardous substances in the products can not exceed the limits, so as not to accumulate in the soil and cause harm to the environment.
  • 3.3.2Plant toxicity
/Lead timeTest method
Plant toxicityA monthRefer to OECD 208 for composting standards

Requirement：The sample compost should have no negative effects on seedling emergence and early growth of higher plants. The germination rate and plant biomass of the sample composts shall be no less than 90% of the corresponding blank composts for plant species.

3.3.2  Earthworm toxicity

/Lead timeTest method
Earthworm toxicityTwo monthsRefer to ASTM E1676 for composting standards

Requirement：The sample compost should have no negative effects on earthworms. The differences in the morbidity or mean weight of surviving worms between the sample compost and the blank compost should not be greater than 10%.
