CONCLUSION:
Pathogenically neutralized sewage has no offensive odour and can simply be used as a fertilizer for food or for non-food crops (bio diesel, shrubs, pasture, flowers etc.).
In pit latrines there are no heavy metals or dangerous compounds once bacterially treated. Nature uses the same bacteria to do the job.
Bioflush is exported worldwide and benefits from certifications such as Environmental Protection Agency in the USA to the PME in Saudi Arabia
