Biolan Toilet Bulking Material is made of peat, wood fibre and biochar. It is suitable for use in dry toilets that separate urine or have a dispenser for bulking material. Its loose and homogenic texture makes it easy to dispense. The bulking material absorbs moisture and balances the humidity of the compost mass. According to studies, biochar accelerates the microbial action of the compost mass. In addition, it binds odours.
