Experience and Projects

​Sydney Water's Malabar Contaminated Biosolids Stabilisation Project.
Biosolids contaminated with mercury were stabilised utilising the internationally patented N-Viro Soil process. At the end of the project, all processed biosolids were deemed acceptable and met the TCLP test for landfilling in NSW. This project was required to be done as an emergency. Extensive plant and equipment were flown into Australia from the United States to successfully complete the project in the contracted time frame.

 

 


N-Viro Soil facility installed for emergency situation at North Head Sewage Treatment Plant when incinerators were decommissioned. Bettergrow processed approximately 150,000 tonne of biosolids into N Viro Soil and developed markets for 100% of the product after three years. The N-Viro soil process converts raw or digested biosolids into a long term stabilised organic alkaline soil conditioner and liming material.
