Food waste recycling ideas: when we think about throwing away useful resources and the waste involved – we often think about food rubbish – i.e. throwing un-eaten or passed sell by date food in to our general waste bins – where it ends up at landfill.


If you are like me – throwing away food is something you never feel comfortable with. Obviously it will never be practical to divert all food waste from landfill – i.e. lots of food thrown away is not suitable for donation to charities etc. However – there are some simple steps that can help reduce food waste going to landfill. We will cover some really good food waste recycling ideas in today’s blog.


The great news is that there are new food waste recycling ideas coming on stream in Australia all the time – and so whether you are a business or a private household – there are lots of options available to you. Let’s get started!

Food waste recycling ideas in 2019 / 2020 – are there viable solutions to reduce waste in landfill?


There are lots of great food waste recycling ideas – which we will run through as below.


Of course – the first thing to say – is that prevention is much better than cure – and so not producing food waste in the first place is the best option. Only buying the food you need etc is a great idea – but of course – we all know that does not always happen in reality.


So assuming we have food waste – what are the best options to avoid general waste and landfill?


 – Can you donate the food to those in need?


There are numerous charities that can help with providing food waste to needy people – for example SecondBite.  However, if the food waste is not suitable for provision to charity – i.e. some charities have strict criteria on what type of waste food they accept- other solutions may be needed.


We cover in a blog the difference between sell by and use by meanings.


This option is less likely for private homes – i.e. for cooked food – i.e. most charities will accept healthy packaged goods – i.e. in tins etc.


You should bear in mind that food waste tends to be very heavy and can increase the weight and hence collection price of your general waste collections service.


 – Do you have a pet?


Simple option – but in years gone by – there was no food waste as it would simply be given to domestic animals.


 – Use it as compost for your garden


Many good food waste recycling ideas – will involve using the waste as compost for your garden. Check out our other blogs on options such as a domestic composter, worm farms etc.


We have also covered why food waste like coffee grounds are really great for your garden. In fact many smart cafes are now giving their regular customers bags of used coffee grounds for their gardens!


There are increasing options such as composters for both home and business use – whereby food waste can be turned into compost for growing vegetables etc – a nice circular economy approach. See for more detail on this topic.


Have you heard of biogas?


One of the best and most exciting new food waste recycling ideas – is a biogas reactor. This device – which can be small enough for a domestic home – lets the food waste rot to release gas – which is used to create electricity.


In fact – some farms etc – produce so much biogas – they could be self sufficient.


In fact – some people argue that food waste is such a valuable source of energy – that it may be sold in the future!


 – Other food waste recycling ideas – such as organic food waste bins


If you can not have a biogas reactor or composter on site – you could consider food waste bins.


For food waste bins – the contents is taken to advanced facilities – where it is either used to produce compost – on an industrial scale – or for electricity generation.


There are also new facilities coming on stream for treatment of organic waste – such as Earthpower in Sydney metro.  As per the facility website:


“The EarthPower facility uses anaerobic digestion technology to convert solid and liquid food waste, into a combustible gas similar to natural gas.”

“The digester gas is then recovered and used as a renewable fuel source in cogeneration engines to produce green electricity. This electricity is then sold to the grid for distribution to domestic, commercial and industrial clients.”


“A by-product of the anaerobic digestion process is a nutrient rich sludge, which is dried and granulated for sale as a fertilizer into the agriculture and horticultural markets. Waste heat from the cogeneration engines is used in the fertilizer drying process and to heat the digesters.”


“When compared to other food waste disposal processes, such as landfill and composting, the EarthPower facility achieves the highest environmental sustainable use of food waste and most favourable environmental outcomes by way of production of green energy, while also producing organic fertilizer for local agriculture businesses, reducing the need of synthetic fertilizers.”


 – One final option – a Waste to Water machine.


If you produce large quantities of food waste – a bin collection service can be very expensive.


If you are a factory or hotel etc with large quantities – you could consider a waste to water machine. This is a machine – where the food waste is turned into liquid and emptied down the sewer – meaning you do not require bins at all!
