The benefits of tallow

Z Bio D is produced in New Zealand from inedible tallow, a locally sourced by-product of the New Zealand agricultural industry that would otherwise be shipped overseas for other uses.

We are confident that tallow is the most suitable option for producing Z Bio D that is good for New Zealand and is as sustainable as possible. Z developed strict sustainability and quality assurance criteria before selecting tallow, the main feedstock component used to make Z Bio D.

 

Tallow benefits include the following:

  • It does not compete with food production as it is a by-product of an existing industry.
  • It is locally sourced and does not adversely impact on the environment.
  • It does not require any additional processes for manufacturing that would impact on the lower carbon benefits of biodiesel.
  • There is a sufficient and long term supply. The available supply of tallow in New Zealand is sufficient to supply Z’s current Wiri plant at a full 40 million litres per annum capacity (as well as a further two to three biodiesel plants of a similar capacity).
  • It does not, in any way, create additional demand for animals. The tallow used in Z’s biodiesel is an existing by-product of the New Zealand agricultural industry that would otherwise be shipped overseas.
