The composting process destroys any potential pathogens such as salmonella and e-coli. The absence of pathogens are verified by routinely testing the finished fertilizer to ensure the health and safety of the product. Suståne fertilizers are also tested for heavy metal concentrations to ensure that the application of Suståne fertilizers do not contribute to the accumulation of metals in the soil. It is because of this attention to quality assurance and product safety that:
Suståne is the only organic fertilizer allowed for export worldwide.
Suståne maintains product registrations in many countries all around the world. These export registrations would not be possible without extensive testing and strict processing controls to ensure and verify the safety of our products.
