KEYNOTE PRESENTATION: An industry perspective on the assessment and management of emerging contaminants
Dr Danielle Toáse, ARCADIS
Emerging contaminants are contaminants of potential concern that have only recently been identified as presenting a public health risk but remain understudied and in some cases are still not regulated. This presentation focuses on emerging contaminants such as per and poly-fluoroalkyl substances, particularly in recycled organics.

A tool kit for inactivating pathogens during composting
Dr Muriel Lepesteur, EPA Victoria
Numerous parameters may influence pathogen inactivation during composting. Using examples, the timing and mechanisms of pathogen inactivation throughout the composting process will be revealed and the implications for process management and future research needs identified.

Nano-stabilization of recycled organics to enhance carbon sequestration
Nanthi Bolan, The University of Newcastle
Applying recycled organics including biosolids, manures and composts to agricultural land could increase carbon storage in soils and contribute significantly to the reduction of greenhouse gas emissions. Recently, there have been increasing interests in the conversion of these recycled organics into biochars in order to reduce the rate of decomposition, thereby enhancing carbon sequestration in soils.

Do water utilities treat Biosolids as a waste or resource?
Peter Donaghy, Queensland Urban Utilities
A new approach to biosolids production is required to ensure the continued sustainable reuse of biosolids. Moving away from a compliance approach to a production facility approach can enable utilities to create value by producing what the customer wants.

Organic Waste to Watts in San Luis Obispo, California
Dr Marc Stammbach, HZI Australia
A new HZI Kompogas® plant opened in North America in 2018. The plant digests green & food waste to generate biogas and high-grade compost as well as liquid fertilizer. The plant converts the biogas into 24/7 carbon-neutral electricity and contributes to meeting California’s Greenhouse Gas reduction and Organics Diversion mandates.

Realising the benefits of Organic Compost – An insight into the research Rocky Point is doing in this field
Mark Raynor, Rocky Point
In collaboration with Environmental Biogeochemistry Research Lab at Griffith University, Rocky Point has been conducting trials looking at the impact of different compost amendments on soil health and the cane yield in sugarcane production. Application of both conventional composting and anaerobic digestion techniques will be introduced.

Thermal hydrolysis at Urban Utilities past and future experiences
Mark Hordern, Qld Urban Utilities
Thermal hydrolysis pretreatment (THP) with anaerobic digestion is used by Queensland Urban Utilities for biosolids stabilisation. A summary of the studies will be presented, including optimisation of THP reaction temperature, influence of THP reaction time, hydrogen sulphide risks and future studies.

KEYNOTE PRESENTATION: Use of Recycled Organics in Modern Agriculture: What long term studies have found and identification of opportunities
Lukas van Zwieten, NSW DPI & Soil CRC
While organic amendments have been used to help produce food for many thousands of years, an understanding of the mechanisms by which they achieve this remain largely unresolved. Recent published literature has investigated long-term results from around the world in an attempt to tease out the most common beneficial effects, and these will be presented with a summary of key opportunities to maximize beneficial effects.
1535
Overcoming “barriers to adoption” to build sustainable markets for an increasing supply of organics
Andrew Dougall, Sustainability Victoria
The increasing diversion of organics from landfill is resulting in an increasing supply of recycled organics. To build a market for this supply we need to overcome farmer “barriers to adoption” of recycled organics. This paper describes these barriers and outlines efforts to overcome them in Victoria.
1555
Understanding nature’s blueprint and working with it
Christopher Cameron, Platinum Compost
This presentation deals initially with a quick look at some common problems faced by many farmers, then going into detail about the mechanism developed to directly address nature’s needs and the results to date of so doing!

Effect of subsoil compost amendment on soil chemical and biochemical processes in Maryborough Cane field
Xiangyu Liu, Griffith University
Organic amendments are mostly carried out on the soil surface layer to mitigate the decline in soil health, however, the effects of subsoil application of composts on soil carbon and nutrient dynamics and plant performance are largely unknown. This work is looking into the key benefits of subsoil organic amendments.

FIELD DAY

ROCKY POINT
Established in 1949, Rocky Point specialises in supplying growing media to Horticulture, Agriculture, Revegetation and the Home Garden sectors. On site at our 70-acre facility we produce all of our own compost, along with the preparation and batching of potting mixes, soils, soil conditioners and mulches. All blends are strictly trialled and tested on site as well as externally through a NATA accredited laboratory.

Our on-site bagging and processing plant packages the growing media into bags, ready to be delivered throughout Australia to our network of retailers. Bulk products are delivered by our own fleet of truck and trailers through Queensland and New South Wales. Our vision is to keep growing a healthy and sustainable future for generations to come.

PHOENIX POWER RECYCLERS
Phoenix is Queensland’s first purpose built environmentally controlled composting facility. The facility features aerated floor composting tunnels in a negative pressure environment where odour emissions are minimised and the conditions for composting are optimised. This makes it ideally suited to accept FOGO and food wastes of all kinds.

Phoenix is also working to develop markets in the agricultural community, through market education strategy forming partnerships with waste producers from the food production and biosolids industries to develop products that are in increasing demand for the health of agricultural soils.
