Centre for Recycling of Organic Waste and Nutrients

The Centre for Recycling of Organic Waste and Nutrients (CROWN) was established in late 2017 as part of the University’s School of Agriculture and Food Sciences, enabled by seed funding from the Queensland Department of Environment and Science.

The establishment of CROWN was prompted by the push to reduce and divert organic waste from landfill into agriculture and horticulture, the drive to find ways of value adding animal manures and reducing nitrogen losses in the manure supply chain, and the desire to improve resource use efficiency, maintain agricultural productivity, reduce negative environmental impacts and move towards a circular economy for organics.

CROWN is a multi-party centre with support from State and local governments, industry bodies, businesses and natural resource management groups, which will unite scientific expertise and professional know-how from across Australia, to be applied to the organic waste challenges faced by a wide range of communities and industries.  A key role of CROWN will be to build linkages between State and Local Government, the waste and organics recycling industry, academics, agricultural producers and natural resource management groups.  CROWN will provide the focus to bring the various interested parties together to develop inter-disciplinary research projects and deliver outcomes and change on the ground.

CROWN will be an independent research, training and advisory organisation that covers all aspects of organics recycling supply chains with the aim of advancing the Circular Economy for Organics.

CROWN will become a central knowledge hub within Queensland and Australia that will promote research, training and extension capabilities in segregating and collecting, processing and utilising organic waste materials and imbedded nutrients, and that will also disseminate technical and practical information for all organics recycling supply chain partners.

CROWN’s activities cover the processing and beneficial use of all organic waste and nutrient streams, including municipal and commercial organics, manure and agricultural wastes, food and fibre processing residues, biosolids and sludges. Our focus however, will be, quite naturally, on the development and assessment of high-quality and fit for purpose recycled organic products and their beneficial use in terms of agronomic, economic and environmental effects. We envisage that a large proportion of our work will cover aspects of utilising raw and composted organic resources for land management and plant production purposes, but will also include the use of products such as digestate, biochar, struvite, or next-generation organo-mineral fertilisers.

CROWN’s focus is on research and development, but also on training and education of farmers, agronomists, composters, waste managers and regulators.

 

Utilising organic residues on Moreton Bay Islands for environmental, community and economic gain

Partner: Redland City Council

Redland City Council has asked CROWN to assist in assessing and establishing local organics recycling supply chains on six Moreton Bay Islands, which will deliver not only environmental advantages, but will also help in achieving community and economic development goals.

 


Developing emerging pathogen diagnostics to support the compost industry

Partners:

  • Dr Paul Dennis, School of Earth and Environmental Sciences
  • Peats Soil & Garden Supplies

Joint funding from Peat Soils and Garden Supplies (SA) and the University of Queensland enabled a project to get under way that will develop and test real-time and digital PCR diagnostic methods for identifying pathogens in composted materials. These new diagnostic tools will facilitate determining the microbial and biosecurity risk not only of compost but of all organic soil amendments and support a move towards risk based product assessments, which is particularly important for horticultural industries.

 


Assessing the benefits of urban derived compost and custom blended fertiliser in intensive horticulture

Partners:

  • Candy Soils
  • Superior Fertilisers

An Australian Government Innovation Connections Grant enables assessing the benefits of using urban-derived compost in combination with microbially enriched fertiliser in a lettuce / broccoli production system. Compost products are used annually at a standard and high application rate, the latter of which aims to satisfy crop P and K demand and also change soil physical properties markedly. Mineral fertiliser rates are reduced according to expected nutrient supply from compost products, aimed at developing a fertilisation regime that accounts for nutrient inputs from organic soil amendment products.

 


AORA Study Awards for Advancing Organics Recycling

Partners:

  • AORA
  • Komptech

CROWN has developed and will administer the AORA Study Awards for Advancing Research, Development and Education in Organics Recycling. The annual awards, which are sponsored by Komptech and presented by AORA aim to encourage post graduate students enrolled at Honours, Masters or PhD level at an Australian or New Zealand university to undertake and excel in research designed to advance organics recycling activities and outcomes.

 


Developing the Circular Economy for Organics on the Sunshine Coast
Partners:
  • Healthy Land & Water
  • Local Governments, organics processors and farmers from Sunshine Coast

This initiative aims to advance the Circular Economy for Organics on the Sunshine Coast by bringing together the key partners in the organics recycling supply chain, i.e. generators of organic waste materials, processors of organic residues and users of recycled organic products to find and develop pathways to a regional, self-sustaining circular economy for organics (CEO) where all supply chain partners benefit and feel rewarded equitably.

Future students projects

Can the use of wastewater precipitation products solve the phosphorous deficit in Australian organic farming systems?

Low availability of soil phosphorus is limiting organic grain production in Australia, holding back development of the organic food sector. Organic growers cannot use superphosphate to supply phosphorous for their crops, but have to use rock or soft phosphate, or tailor-made compost with elevated phosphorus levels. A possible alternative for organic farmers might be the use of wastewater precipitation products such as struvite or calcium phosphate, both of which are produced from the decant water of anaerobic digestion facilities processing wastewater from municipal, food processing or intensive animal industry sources.

The project will seek to clarify whether and under which conditions particular sources of phosphorus derived from wastewater, such as struvite or calcium phosphate, can be allowed as inputs in certified organic farming systems in Australia.

Furthermore, the project will also investigate, if these products are allowed inputs in overseas countries, and if so, under which conditions the use of these compounds is allowed? If wastewater precipitation products are not allowed inputs into organic farming systems at present, what possibilities are there to have this input accepted in the future? This project will seek to answer key questions concerning the situation in Australia and internationally.

Answers to these questions, together with a cost benefit assessment of using phosphorus inputs currently allowed in Australian certified organic farming systems in comparison with potential future alternatives, will be presented in a discussion paper for the organic farming community.
