Reduced waste and alternative products
The best way we can reduce the amount of waste is to follow the five R’s:
Waste is not only harmful and costly—it is also a lost economic opportunity. Recovering and reusing valuable materials reduces the demand for new materials and the fossil fuels needed to produce them. It can also build new industries and markets, and create new jobs. This is known as a circular economy.
The easiest place to start good recycling habits is at home. Separating recyclable waste and using your recycling bin is a great way to recycle household items. Items usually allowed in council recycling bins include:
Using your recycle wheelie bin is a great way to recycle household waste products. These bins are normally provided by your council and what can be recycled may vary between Councils.
Items usually allowed in them include:
Many councils provide separate bins for green waste, which is turned into compost and used in green spaces and agriculture.
Replace plastic items
Plastic is one of the most pervasive waste items on land and in the ocean. In Queensland, single-use plastics are being phased out, starting in 2021. Bioplastics are often promoted as a viable alternative. But unless conditions are ideal, such as in a commercial composting environment, bioplastics can take as long to break down in the environment as petroleum-based plastic.
Plant-based plastics are made from a variety of sources such as polylactic acid (PLA) from corn waste. PLA is more sustainable than fossil fuels and can be used to make drinks bottles, food containers and film.
Mushroom root packaging
Mushroom root (mycelium) has been used for various products, such as vegetarian meat alternative and clothing. It can also be mixed with agricultural waste to ‘grow’ packaging. Some companies are using mycelium foam as a replacement for polystyrene foam.
Bagasse is a by-product of sugarcane processing, which can be easily moulded into packaging for food service. The product is similar to polystyrene, except it is biodegradable, compostable and more sustainable to produce.
Light sticks in longline fishing
Single-use light sticks are used to attract fish in the longline fishing industry, but they can be ingested by the endangered albatross and other seabirds. Researchers are trying to develop reusable LED lights for longline fisheries. Also being investigated are ‘hookpods’ that protect the hooks from sea birds during longline fishing. Longline fishers are already required to use bird-scaring devices when setting their lines—in one South African fishery this resulted in a 40 percent decline in injured birds.
Seaweed water bubbles
Edible bubbles, made from seaweed, are an alternative to plastic water bottles.
Stone paper and plastic
Stone paper is made from calcium carbonate. It is printable, recyclable and waterproof, and uses less water and energy to produce than regular paper. Stone paper has possible packaging applications, such as food packaging, paper bags, takeaway food cartons, greaseproof paper and zip-sealed bags.
Palm leaves can be used to make packaging for food, such as fresh fruit, vegetables and nuts, and soap. The Areca Palm is ideal for this as its leaves fall naturally and can be collected and moulded. The leaves are a natural waste product and the final packaging product is biodegradable.
Edible six-pack ring
Some breweries are using material that is biodegradable, compostable and edible by marine life for their six-pack beverage container rings. The rings are made from barley and wheat remnants, a by-product of the brewing process.
Wood pulp cellophane
This product is like cellophane, except biodegradable. It is semi-permeable and can be used in packaging:
Prawn shell plastic bags
Scientists are developing plastic alternatives from unlikely things. One is chitosan, made from prawn and crab shells—usually a waste product. Not yet commercialised, it could potentially be used as a package for food and drinks.
Casein – the protein found in milk – has been used to make plastic for over a century, but it has largely been replaced by the more hard-wearing, long-lasting petrochemical variety. Technology has been developed that combines the protein with clay and a reactive molecule (glyceraldehyde) which make the plastic much stronger, but still biodegradable. Milk plastic could be used for the detergent industry (e.g. dishwasher pods) as well as the food and beverage industry, pharmaceuticals and agrochemicals.
