Fast fashion in Australia is an industry worth over $2 billion annually, but the damage it is causing the planet is immense. On average 6000kg of apparel is destined for landfill every 10 minutes. We transform garments destined for landfill into desirable one-off pieces, raising money for charity and saving them from landfill. Pre-loved or unsold garments are hand-cut, sewn and altered in Melbourne, creating pieces that encourage a radical rethinking of the industry.

The wine industry generates 68,000 tons of grape waste annually. In landfill this waste releases methane, a potent GHG. Bottling & transport account for 2/3 of the wine industry’s carbon footprint and broken glass can cause recyclers to refuse service. T’wine uses emerging biotech to design out grape and glass waste. Through millennial focused product & service design we aim to turn the wine industry into a circular economy

The problem is contaminated organic waste going to landfill. The solution is vertical separation (VS), which separates plastic film and other contaminants from organic matter to produce a product with value. The pulped organic matter is an ideal feed stock for anaerobic digestion either on site or remotely to produce biogas and digestate (bio fertiliser). Current kerbside collection arrangements will not be interfered with.

Our principal objective is to reuse plastic waste that is thrown away daily. According to National Waste Report 2018 stats and figures, just 12% of plastic is recycled in Australia. Of the 2.5 million tonnes, 20,000 tons are destined to energy recovery, and around 2.2 million tonnes to landfill. In Victoria a total of 88,000 tons of plastic waste were exported to China, Indonesia, Malaysia and Vietnam in 2019.

An online marketplace, where suppliers, consumers, businesses and government can connect in an ‘eBay’ style platform to buy and sell types of reusable waste. Almost any type of waste product can be reused in some form, but it must be directed to the right destination. A combined platform would benefit the commercial industry. Buyers would include private business and government entities with a share of profits to be put back to the community.

Hayley Rolfe and Narendran Subramaniam

We are working with SMEs to introduce circular economy practices through use of the Ardea Waste management platform. The platform helps businesses identify and engage reuse and recycling options for their waste. Our goal is to meet and exceed government targets of 75% waste diversion from landfill by finding better treatment & uses for commercial wastes within local industries. We aim to reduce waste, keep resources circulating and enhance local connections.

My idea is Bin Bot, an AI-driven bot application with cognitive capabilities. It's compatible with popular messaging applications such as Messenger and WhatsApp, as well as smart home devices such as Google Nest, Hub and Alexa Echo. You can ask questions about your waste, and know what goes where and how soon. It’s quick, informative and dare say fun. Most importantly, Bin Bot helps you help the environment and make Victoria a better place.

Narendran Subramaniam and team

BinSense has developed an IoT sensor and platform that solves the problem of contamination in recycling. Mainly due to contamination, less than 30% of recycled materials collected are recycled. In some areas, due to supply issues and recent fires, nothing is recycled and is therefore passed to landfill. Putting recycling into landfill costs councils more per tonne, is a poor outcome for the environment, and not what the population wants or expects.

We're gamifying waste collection by using Machine Learning and image recognition to identify what's recyclable. Our Internet of Things device is attached to the top of each Melbourne city bin, it tells someone that a coffee cup isn't recyclable. Our UV camera detects if the recycling bin is contaminated with food. An interactive graph shows how close the bin is to being too contaminated. We can also notify garbage trucks to collect contaminated recycling.

Bricolage Dynamics converts municipal glass waste into a sand resource. It solves the problems of :

• Increased landfill: cost of transportation and disposal.
• Finite resources for material production, as glass comes from sand, which is the world’s second most used natural resource.
• Lost revenue: $1 billion in lost economic potential.

In our society, there is a false notion that materials are in inexhaustible abundance. For decades, materials have not been used to their optimal value and have left a trail of environmental destruction, social injustice, and financial loss during their life cycle. My idea will address the optimistic path to live within planetary boundaries, by connecting stakeholders and allowing for a unique process of transparency.

Australia has a high CO2 emission per capita, the result of the textile industry and burning fossil fuels. Our aim is to improve home energy efficiency through a low-cost insulation material made from the plastic fibres of discarded clothes. The insulation is attached to windows, decreasing the thermal bridge between the material and the interior of the property. This increases the Lumens and decreases the UV rays inside the property.

Around half of household garbage is food waste. Food can be fuel - not only for our bodies, but our neighbourhoods, communities and cities. This idea starts with 5 main components:

1. In-home food waste 'bins' that are strategically designed.
2. Stickers/magnets that are smartly designed to go on in-home waste bins (no more food scraps).
3. City-wide food waste collection.
4. Communication, education and marketing to back the change.
5. Ultimately, it's compulsory to separate food waste.

We're dedicated to solving the disposable cup problem. 1 billion coffee cups are disposed each year in Australia and 90% of these go to landfill. This equates to ~60,000 kg of plastic waste annually. Some cups claim to be compostable, but infrastructure to manage these cups is limited. We have an innovative solution that solves the problem, an edible cup that is waste free. It functions like a takeaway cup without harming the planet or compromising convenience.

The textile waste generated in the fashion supply chain is something ignored by many, but proven to have unprecedented adverse effects to our environment. The ‘sample’ products, which are tested, fitted and photographed are generally of no value beyond that. These samples then end up burnt or thrown into our landfill. Our 3D Designs along with virtual try-on tech turns physical sampling to digital sampling and hence reduces over production and trash.

Australian women are the biggest consumers of fashion in the world, and they don’t wear 70% of their wardrobe. This leads to massive waste and pollution. For example, in Australia alone every 10 minutes six tonnes of textiles go to landfill. To cope with this, some eco-stylish ladies attend clothing swap gatherings. However, the events are rare and many people can’t attend because of their busy lifestyles. If we bring this concept online, many more women could take part in it.

Reusable cups as a waste minimisation solution has been a great achievement for Melbourne. However, with millions of cups in circulation, there is no program in place to facilitate a circular end of life solution. Our idea is to create a program that connects current users of reusable cups within Melbourne City to a recycling program that closes the loop, enabling products to be appropriately recycled and rehomed into new products rather than ending up in landfill.
