Biodegradable Chemicals

Good day All

The general ​​definition of ​​biodegradable ​​is anything ​​that biologically ​​degrades with ​​time. This time ​​can be 1000 ​​years, 2days or ​​any amount of ​​time. So ​​looking at this ​​definition, ​​then everything ​​is technically ​​biodegradable. ​​

Some ​​chemicals used ​​for cleaning ​​and disinfection ​​(especially in ​​food industry) ​​has also been ​​termed ​​biodegradable.​​ The WHO ​​said Sodium-​​diChloro-​​Isocyanurate is ​​a biodegradable ​​chemical. ​ ​

So if certain ​​chemicals are ​​stamped ​​biodegradable ​​then this ​​deviates from ​​the general ​​definition of ​​biodegradability.​​  ​ ​

So what is ​​actually the ​​meaning of ​​biodegradability ​​when it ​is ​being used ​to ​stamp ​products ​as ​biodegradable.​ ​Is there a ​​time to degrade ​​which is used ​​as reference. ​​Example, ​​anything taking ​​>5 years is ​​termed un-​​biodegradable. ​​Or what is the ​​criteria to ​​stamp a ​​chemical as ​​biodegradable? ​​

Same as with ​​labs that terms ​​all parameters ​​going through ​a ​0.45um ​filter ​as "​soluble". ​But ​the same ​​parameters ​​termed soluble ​​passing through ​​a 0.45um ​filter ​is not ​soluble ​​passing though ​​a 0.03um filter.​​ So the 0.45um ​​size was used ​​as reference to ​​create the ​​universal ​​definition of ​​soluble. ​ ​
