FAQs on Kapoop Bags

Q: What are Kapoop Bags made of?

A: Kapoop bags are made of:

  • 100% corn starch (making it plant-based) - not suitable for consumption
  • polylactide (PLA) 
  • polybutylene adipate-co-terephthalate (PBAT)

Q: How long does it decompose?

A: Each bag will decompose after 90-180 days depending on its environment. 

Q: Can I recycle my Kapoop Bag?

A: No. Since it will naturally decompose, you cannot use it for any other purpose.

Q: What is PLA?

A: PLA is a biodegradable and bioactive thermoplastic aliphatic polyester derived from renewable resources, such as corn starch (in the United States and Canada), cassava roots, chips or starch (mostly in Asia), or sugarcane (in the rest of the world). 

 Q: What is PBAT?

A: PBAT is incredibly biodegradable and will decompose in home compost leaving no toxic residues, it is currently partly derived from petrochemicals. It is added to make the product degrade quickly enough to meet the home compostability criteria. 

Q: Do you have a certification?

A: YES! Read below.

This certification ensures that the product can be industrially composted and that not only the plastic but also all other components of the product are compostable, e.g. colors, labels, glues and – in case of packaging products – residues of the content.

Testing for certification according to EN 13432 encompasses:

  • Chemical test: Disclosure of all constituents, threshold values for heavy metals are to be adhered to.
  • Biodegradability in controlled composting conditions (oxygen consumption and production of CO2): Proof must be made that at least 90 percent of the organic material is converted into CO2 within 6 months.
  • Disintegration: After 3 months of composting and subsequent sifting through a 2 mm sieve, no more than 10 percent residue may remain, as compared to the original mass.
  • Practical test of compostability in a semi-industrial (or industrial) composting facility: No negative influence on the composting process is permitted.
  • Ecotoxicity test: Examination of the effect of resultant compost on plant growth (agronomic test).
