An Overview Of Our Solution
The Yarra Riverkeeper Association (YRKA) is a leading member of the Global Waterkeeper Alliance that advocates for the protection of the Yarra River’s waterways, parklands and riverbanks in Melbourne, Australia.
Recognising the harmful effects of litter and polystyrene pollution to the health of the waterways, the YRKA in conjunction with Clearwater Group conducted strategic vacuum removal of microplastics, complemented by community members cleaning sections of the Yarra and Maribyrnong Rivers on foot and in kayaks. Data on polystyrene manufacturers, high-volume users, recyclers and distributors were researched and mapped using an interactive geographic information system.
The initiative not only removed significant amounts of waste from the Yarra River precinct, but also prevented litter flow into the marine ecosystem of Port Phillip Bay.

Challenge
Analisis Konteks
Litter, microplastics and polystyrene cause direct harm to both terrestrial and aquatic wildlife through ingestion. It causes soil pollution through the breakdown of microplastics and pollutants into reedbeds and riverbanks, and results in the quality of water to decline due to respective chemical compounds leeching into waterways from breakdown. As various animal, fish species consume polystyrene, it can bioaccumulate and be ingested in higher quantities by humans when consuming fish and seafood products.
The Yarra is Melbourne’s most important open green space and so a large amount of litter and polystyrene pollution not only has severe environmental impacts, but also aesthetic and social impacts on recreational activities such as jogging, kayaking, water skiing and dragon boating. Both the Yarra and the Maribyrnong Rivers are the key sources of litter and polystyrene pollution with an estimated 800 million bits of rubbish estimated to flow into Port Phillip Bay annually.

Our technical solution of the initiative was to both identify and map litter pollution hot spot sources and then subsequently remove large amounts of waste from the Yarra River catchment. Our initiative reduced water pollution through a boat-mounted vacuum removal system named “Mr. Snuffleupagus” which was specifically designed to tackle hard to reach areas such as reedbeds and riverbanks removing over 36,500kgs of fine litter.
Complementing our technical solution vacuum clean-ups, the association also held seven large –scale community Yarra Blitz events where a total of 712 individuals, consisting of the public, volunteers and community environmental groups, cleaned sections of the Yarra and Maribyrnong Rivers by foot and kayak. This community effort removed 1580.5 kgs of community collected waste.

We aim to reach as many members of the community as possible to develop a sense of civic pride and shared sense of environmental water stewardship. By inviting the community to get involved in the clean-up efforts, the initiative further engaged and educated the public and developed recommendations to prevent future pollution.
Whilst litter pick-ups on the riverbanks and parklands are welcome, kayaking and collecting waste whilst on the water inspires a deeper connection to the natural environmental to invoke a greater sense of responsibility and behaviour change.
Building on our polystyrene research and site identification we hope to continue to conduct lab analysis research to identify and match the sources of pollution to specific brands and products. As part of this initiative we have motivated and educated school children and the general public to make stronger, more conscious consumer choices. Our webinars and presentations have promoted awareness to the prevalence of microplastics in cosmetics and toiletries, whilst educating on alternatives such as salt, walnut and apricot shells, as well as alternatives to polystyrene such a mycelium. This behaviour change advocacy was also promoted at a community leader round table facilitated by Keep Victoria Beautiful.
In addition, our initiative has inspired stronger dialogue to work towards recommendations to the Victorian State Government on reviewing polluter and environmental legislation.

Choice Architecture: By educating the public about the prevalence of polystyrene in common household cleaning products, cosmetics and toiletries, we have motivated and educated school children and the general public alike to support the use of natural, biodegradable alternatives to microplastics.
Emotional Appeals: Event attendees and the general public have expressed their disappointment, shock and sometimes anger over the prevalence of litter in Victorian waterways. Seeing how beloved Australian wildlife is directly affected also generates a large amount of emotion in the general public.
Information: Community education, consumer awareness and lobbying for industry reform and greater environmental protection are at the forefront of our organisation’s work. Our project reports can be accessed here: https://yarrariver.org.au/reports/
Social Influence: The visual amenity and cleanliness of the river are vital for recreational purposes such as boating, rowing and water sports
Implementation
Jelaskan implementasi Anda
By targeting litter hotspots and reedbed clusters, our technical solution of vacuum removal, removed over 36,500kgs of microplastics and fine litter particles between late 2018 and early 2020. These were complemented by seven large –scale community Yarra Blitz events where a total of 712 individuals, consisting of the public, volunteers and community environmental groups cleaned sections of the Yarra by foot and kayak removing 1580.5 kg of waste. Whilst this indeed was a very generous turnout, attendance was slightly hampered by less than ideal weather conditions.
In order to identify potential sources and distributions of polystyrene on the Yarra River, data on polystyrene manufacturers, high-volume users, recyclers and distributors were first collected using desktop research. These potential sources were then mapped using an interactive geographic information system which also included data on major polystyrene hotspots on the Yarra River (informed by the Yarra River Blitz project), drainage catchments, stormwater outlets on the River, and the locations of each Bandalong Litter Trap in the Yarra.
Field investigations were conducted and guided by the results of the desktop study on potential sources located around the Yarra River. Data collected ranged from the location of the site to specific information on the status, type and condition of stormwater drains inspected. By identifying key hotspots and sources of polystyrene litter we aim to continue to work alongside industry and key stakeholders to help reduce and tackle water pollution by mitigating at the source.
A large barrier to our polystyrene study was the level of funding allocated, which meant that each site was only visited once. Limited observation frequency of each site also meant difficulty in identifying the correct type and source industry of polystyrene observed in the environment. Funding restrictions also means that specific sourcing lab analysis could not be conducted.

The Yarra Riverkeeper Association partnered with Cleanwater group to assist in mapping, GIS analysis, water consultation and research assistance. Cleanwater group provided additional man-power and provided boat-mounted vacuum system to remove microplastics from reedbeds.
Parks Victoria, Melbourne City Marina and Melbourne Water gave in-kind storage access, boat mooring, shared data on known litter hotspots on park riverbanks and assisted to promote events and conducted litter audits.
Port Phillip Eco-centre audited and collected litter from microplastic trawls.
This project was made possible by kind funding from the state of Victoria’s Department of Environment, Land, Water and Planning’s Port Phillip Bay Fund.
The partner organisations came together to assist one another for a common environmental cause and issue that centrally affects many Melburnians, greatly increasing the amount of data collected and the scope of the project. This project has helped us develop an integrated understanding of litter in the river and collaboration was essential. This new knowledge has improved the Association’s ability to speak for the river and to advocate for its protection.
Recognising efforts in water stewardship and litter reduction, the organisation recently won two premier sustainability awards, the environmental protection award and the premier’s recognition award which was hand-selected by the Honourable Premier of Victoria (Head of State) Daniel Andrews.
