BIG BIO Organic Fertiliser™

BIG BIO Organic Fertiliser™ is due for launch in early March. Thanks for your interest, please stay in the loop.

BIG BIO Organic Fertiliser™ labelNew Generation BIG BIO®

Our new product is called BIG BIO Organic Fertiliser™ and is derived from food waste and designed to close the loop on food waste by returning the nutrients from food waste to the soil. The product contains useful amounts of Nitrogen (N), Potassium (P), Phosphorus (K), Calcium (Ca), and Sulphur (S) in plant available form. Trace elements include Iron (Fe), Manganese (Mn), Boron (B), Copper (Cu), Zinc (Zn) and more. The product is also rich in soil microbes, the living organisms that are so vital to soil health.

BIG BIO Organic Fertiliser™ is in the final stages of development and set to change the game in the new circular economy.

BIG BIO Organic Fertiliser™ contains in part the BIG BIO castings and leachate but also incorporates other sources of food waste derived nutrients in order to have a much bigger impact than we could envisage from worm derived products alone.

In the city, we’ve found two technologies of great interest, AD (Anaerobic Digestion) and Food Waste Dehydrators (sometimes called organics units). AD can use food and other organic waste to extract methane which can then be used to generate electricity. A good example is Yarra Valley Water’s AD plant at Wollert in Melbourne. Food waste dehydrators are great for reducing the volume of food waste in densely populated areas where minimising truck movements is an important part of the solution.

Both the technologies mentioned here produce residual material with no clear value add – until now. After 18 months of focussed R&D including projects in partnership with CSIRO, Yarra Valley Water and Closed Loop, and with the support of AusIndustry’s R&D Tax Incentive Program, we have developed an organic fertiliser that closes the loop on the AD and dehydration processes and incorporates the beneficial soil microbes from worm castings.

Future Development

Most importantly the manufacturing process for BIG BIO Organic Fertiliser™ is infinitely scalable which enables production of a low cost, high value fertiliser for urban and rural farming and gardening applications giving all Australians access to a product that is part of the solution to food waste and declining soil health.

Our vision includes licensing this technology throughout the world giving cities, towns and even small rural communities an opportunity to create jobs and do good while making money. For more information please email
