There are three types of biodegradable wet wipes:
- As defined by the marketing department. These degrade somewhere between 20 and a hundred years from when they are buried and are usually made of rayon.
- “Flushable” wipes. A new category. Properly they should be 100% cellulose, short fibers and degrade within weeks. See above for long fiber part plastic labeled by marketing.
- “Real” biodegradable wipes. Often found in hiker boxes. These start falling apart as soon as the seal is broken (which is why they are often dropped off in hiker boxes).
How can you tell which is which and not just a come on for affiliate marketing links or otherwise selling you a bill of goods?
There is a UK standard, “fine to flush” that is a good indicator. EDANA & INDA standards of compostability are also good indicators.
Note that all of these standards get abused by marketing departments. Also, what is appropriate for a cat hole (defined as biodegrading as fast or faster than toilet paper) is not always good to flush.
We still need a better standard out there.
