Carbon abatement from organics diversion
Robin Gonzalez, MRA Consulting Group
Waste contributes to approximately 3.7% of Australia’s greenhouse gas emissions, which are mainly generated from food and organic waste. The Clean Energy Regulator has created the Source Separated Organic Waste (SSOW) method to incentivize proponents to divert organic materials from landfill. MRA will provide an overview of the benefits associated with the SSOW method.
Fertilizer value of wastes and their corresponding biochars
Md Zahangir Hossain, GCER – University of Newcastle
The surplus manure and biosolids can be managed through biochar production to make them as potential fertilizers. These wastes are rich in plant nutrients, and after synthesizing biochar these biomasses became enriched with remarkable nutrients (particularly N, P and K) and high pH values as well as reduce heavy metals availability.
Innovative approach for identification of microplastic in biosolids and soils
Dr Mehran Rashti & Dr Maryam Esfandbod, Griffith University
Microplastics have been notified as a newly emerging contaminant in international scale, so the awareness about this issue is slowly increasing within policy.The proposed methods is innovative for MP quantification developed based on reviewing worldwide available literature where collective techniques were utilised to provide the best possible outcome in obtaining MPs from samples with high organic matter content whereas the current methods is not suitable.
The economics of recycled organics in vegetable production
Liam Southam-Rogers, Applied Horticultural Research
Recycled organics can be used to improve soil conditions and create profitable increases to yield in vegetable production. Two demonstration trials were established, and the economic performance of recycled organics was measured along the life of open-field popcorn crop and radish crop under a greenhouse.
Accelerated Thermophilic Aerobic Digestion (ATAD) for Rapid Composting
Sonia Ghiggioli, Central Queensland University
To optimise the time/temperature/input variables within the ATAD biodigester technology process at the pilot plant of President Biotech Pty Ltd to produce an unrestricted compost to meet the Australian Standard AS4454 for direct application in agriculture.
Considerations for Compostable Packaging in Australia
Australian Packaging Covenant Organisation (APCO) in partnership with AORA and ABA
Considerations for Compostable Packaging in Australia is a new APCO resource that addresses confusion, and provides greater supply chain transparency, around compostable plastic packaging applications in Australia. Designed for brands, retailers and manufacturers, the new resource provides the key insights needed to make informed decisions about compostable packaging. The guide covers:
- A definition of ‘compostable packaging’ and an overview of current organics recycling practices in Australia
- The challenges and opportunities for compostable packaging within existing infrastructure
- The crucial need for clear labelling and consistent communication to consumers.
Spreading Compost to Wider Fields
Stephen Ockerby, AgSight Pty Ltd
The effects of compost on the soil and plant growth are well-known. This (poster) paper explores how to use what is often a limited supply of compost to derive added benefits from more-and-more farmed and managed lands.
