10 ways to reduce food waste at home
Australians are said to generate approximately 19 million tonnes of organic waste every year – and one recycling expert is urging householders to rethink their attitude to this material as a critical step in the process of recycling more.
“We look for ways to ‘get rid’ of waste but we need to start managing this material as a resource,” he says.
More recycling and less waste
Martin points to Brisbane City Council’s Northey Street City Farm, which turned four cubic metres of food waste dropped off by local residents into compost, as a great example of what can be achieved – but still a drop in the ocean.
“Every little bit helps, but consider what Northey Street City Farm is achieving and then compare that with the 19 million tonnes of organic waste Australians generate every year,” he says. “Four cubic metres is a great start but when we look at the industrial scale of this, that method is not the answer to this problem.
“We need to transition to achieving this at an industrial scale with quality products going to enhance the production capacity of agricultural soils.”
Despite the government sector taking up the population’s call for more recycling and less waste, Martin says the expectation for instant – or at the very least, short-term – gratification is a little harder to achieve.
“If you think that a single, state-of-the-art composting facility is going to cost between $12-20 million, and you need one at every council depot to make it work, then it’s not an overnight fix; it’s something we need to transition towards,” he says.
“Also, it’s important to remember that only 50 per cent of the food that is manufactured ever makes it into a human body – that’s the stuff that perishes in transport, doesn’t get sold in the supermarket and doesn’t leave the farm. It’s a staggering amount.”
Ways to reduce food waste
While most states have introduced landfill levies to drive recycling, Martin says we can all help to deal with one of their biggest issues: contamination. Rusted out barbeque plates, dog toys, tennis balls – everything gets thrown in.
“Ninety per cent of Australian families would have a plastic bag on the kitchen bench and after dinner they scrape food waste into the bag, along with some packaging, and maybe something the dog’s dropped, then they tie it up and put it in the bin,” he says. “Now that is just utterly useless in terms of the recycling process.”
“The sector works very hard on getting contamination out of product but it would be a lot easier if it didn’t go in in the first place. Simply put, it’s not waste, it’s a wasted resource.”
Here are 10 helpful tips to help you create less food waste:
- Plan your meals for the week before you go shopping and buy only the ingredients you need
- Look in your fridge and pantry first to avoid buying food you already have
- When you get home from shopping, wash, dry, then store fresh food items in clear containers so you can easily see what you have in the fridge
- Properly store fruits and vegetables for maximum freshness; they’ll taste better and last longer
- Fruits that release natural gases as they ripen need to be stored separately. Here’s some information on how to prevent spoilage
- Freeze food you know you won’t be able to eat in time, such as bread and sliced fruit, before it spoils
- Cook or eat what you already have at home before buying more
- Produce slightly past its prime can often be used for soups, stock, casseroles, stir fries, baked goods and smoothies
- Use expiration dates as a guide and first check whether food smells, looks and tastes alright before you throw it out
- Finally, avoid filling your fridge to the brim as it’s easy to forget about food you can’t see. If this is unavoidable, rotate older ingredients to the front
The Australasian Waste & Recycling Expo takes place on the 23rd and 24th August at the Melbourne Convention and Exhibition Centre. Martin’s presentation is on Wednesday 23rd of August.
