Včasih se brez kroma in kovin strojeno usnje imenuje tudi bio usnje. Ta izraz pa ni pravilen, saj tudi s kromom strojeno usnje ob pravilni izdelavi ni škodljivo zdravju.
Običajno se izraz Bio usnje uporablja v kombinaciji z rastlinsko strojenim usnjem. To je tudi razumljivo, saj rastlinsko strojenje že zveni Bio. Pri ‘‘Sporu‘‘ med prevladajočim krom strojenjem in rastlinskim strojenjem pa moramo upoštevati celoten postopek.
Pri znanstveni raziskavi oziroma primerjavi ugotovimo, da sta oba postopka več ali manj enako prijazna ali neprijazna za okolje.
Slabost vsebnosti kemikalij pri krom strojenju moramo postavit ob stran slabosti pri rastlinskem strojenju. Slabosti rastlinskega strojenja so:
- Sredstva za rastlinsko strojenje se pridobijo v daljnih deželah (podiranje in mletje dreves).
- Transportne poti so dolge, kar pomeni veliko poraba goriva pri prevozu do končega mesta uporabe.
- Poraba po kilogramu je veliko večja kot pri krom strojenju
- Količina odpadne vode je zaradi večkratnih ponovitev veliko večja kot krom strojenju.
