Australia is covered in billions of tonnes of plastic and yet <10% is recycled today. Polyurethane (PU) is ubiquitous in our everyday lives, from lacquer coatings to elastane clothing to durable foam padding in car seats, cushions and mattresses. Currently, there are few avenues for PU recycling and much ends up in landfill e.g., a single mattress produces 15-20kg of PU foam waste. Luckily, biodegradation of PU can occur naturally via various microbial means and from insects, like Galleria mellonella larvae. The overall aim of this research project is to understand plastic biodegradation and translate nature’s solutions into flexible and efficient synthetic enzyme technologies that can sustainably recycle commonly used PU foams.

Summary
Moreton Bay is a 1,500 km-squared urbanised estuary adjacent to one of the fastest growing regions in Australia. Rapid population growth creates a challenge for wastewater utilities to deal with the increase in nutrient loads. This includes the single largest asset of Queensland Urban Utilities (QUU), the Luggage Point Sewage Treatment Plant, at the mouth of the Brisbane River that discharges into the bay.

Moreton Bay is a 1,500 km-squared urbanised estuary adjacent to one of the fastest growing regions in Australia. Rapid population growth creates a challenge for wastewater utilities to deal with the increase in nutrient loads. This includes the single largest asset of Queensland Urban Utilities (QUU), the Luggage Point Sewage Treatment Plant, at the mouth of the Brisbane River that discharges into the bay. At the same time, on the eastern side of Moreton Bay, the Queensland rock oyster industry faces reduced productivity due to environmental change, disease and algal blooms, and challenges associated with the business risks presented by monoculture. Here, communities on Minjerribah (Nth Stradbroke Island) are also investigating new opportunities during their transition away from sand mining, and Quandamooka Yoolooburrabee Aboriginal Corporation (QYAC) has Native Title on a large tract of the Moreton Bay Marine Park, which to date is mostly unutilised.
Seaweed production offers a unique and timely solution to address some of the economic, environmental and social challenges in Moreton Bay. Seaweed farming is a “no-feed” form of aquaculture; it is zero waste and compatible with oyster farming and marine park zoning. Seaweeds grow quickly and strip nutrients from the water column, draw down carbon dioxide and can remove pollutants such as heavy metals. At the right scale, seaweed farming will reverse environmental change. Because of this, QUU and the University of the Sunshine Coast (USC) are evaluating how much nutrient can be extracted from the bay as an offset for their discharge licences, to avoid substantial capital investment in sewage treatment whilst delivering better environmental outcomes for each dollar spent.
At more than 25 million tonnes per year, seaweed is the largest marine crop in the world. Southeast Queensland is the perfect setting for developing a seaweed industry – ample light, warm water and existing aquaculture leases with farmers, such as Moreton Bay Rock Oysters (MBRO), seeking to diversify their production. Investing in seaweed production will create a new industry for our coastal communities with accountable environmental services and sustainable products.
Objectives: 1. Compare and contrast the nutrient offset and sequestration potential of target seaweeds in controlled experiments 2. Evaluate seaweed production systems using commercially available aquaculture equipment during the scale-up of target seaweeds 3. Determine the yield and properties of harvested seaweed from a year-round pilot production trial at two sites within Moreton Bay 4. Assess the potential effects of seaweed culture on water quality and adjacent marine animals and vegetation 5. Model the removal of nutrients, carbon and other pollutants and the offset capacity of seaweed farming for Moreton Bay Read moreRead less

Summary
The primary need of this project is to facilitate a profitable Longspined Sea Urchin fishery to move the industry away from subsidies. A large-scale sustainable fishery is seen as the most feasible and sustainable way to apply downward pressure on the rapidly expanding Sea Urchin population in Tasmania. Longspined Sea Urchin populations have grown to some 20 million (5,500 tonnes) and have resulted in 15% of the Tasmania East Coast reefs becoming unproductive urchin barren, up from 3% 15 years ....The primary need of this project is to facilitate a profitable Longspined Sea Urchin fishery to move the industry away from subsidies. A large-scale sustainable fishery is seen as the most feasible and sustainable way to apply downward pressure on the rapidly expanding Sea Urchin population in Tasmania. Longspined Sea Urchin populations have grown to some 20 million (5,500 tonnes) and have resulted in 15% of the Tasmania East Coast reefs becoming unproductive urchin barren, up from 3% 15 years ago.
Subsides for the Longspined Sea Urchin harvest commenced in 2016 and in the last 3 years some $500,000 has been spent. This initiated significant investment in the industry to facilitate export market establishment and resulted the 2019 harvest reaching an excess of 550 tonnes, now Tasmania’s 3rd largest wild fishery by weight. However, the industry needs to move away from subsides and waste utilisation is seen a viable option to turn a current financial cost (estimated at $80,000 in 2019 to dump 400 tonnes of waste generated) into an income stream.
FRDC 2016-208 highlighted the significant potential of sea urchin waste utilisation in the agricultural industry and called for commercial upscaling of trials. This project is designed to meet that need. Based on this, the Abalone Industry Reinvestment Fund (AIRF) has committed to providing $538,686 in kind to initiate the project. This whole of project application is to allow multi-season agricultural trials of waste products to obtain scientifically and industry meaningful results, allow testing on perennial crops (such as cherries) and to employ a dedicated post-doctoral researcher on the project.
In the push for sustainably produced food, agricultural industries are demanding alternative nutritional sources to synthetic fertilisers. Urchin waste is comprised of two major parts: gut waste - a nitrogenous rich liquid which can be converted in a stable drench or spray and; shell waste – a calcium and boron rich solid which can be dried and powdered for use as a soil ameliorant. As such this fisheries enhancement project will additionally for fill this agricultural need.
Objectives: 1. To develop commercial scale processing equipment of sea urchin waste. 2. Determine the nutrient composition and plant bioavailability of nutrients from two high throughput waste streams: liquid gut waste and dried powdered shell waste 3. Evaluate the agronomic benefits of liquid gut waste as a frost retardant in perennial tree cropping (cherries) 4. Evaluate the agronomic benefits of powdered shell waste as a soil ameliorant in a wide range of annual and perennial cropping systems 5. Undertake a cost benefit analysis comparing fertiliser products (foliar sprays and/or soil conditioners) from this work to other products on the market to assess if the products are commercially viable Read moreRead less
