Reducing Food Waste

by Gavin, from The Greening of Gavin

Recently, I read that over 30% of all household garbage is food waste; peel, plate scraps, rotten food, tea bags, etc.  Now this figure does not include food waste from Supermarkets, agriculture and the food industry in general.  In landfill these organic scraps become buried under tonnes of other waste and earth in an oxygen deprived environment.  As they breakdown they produce methane which is 25 time more potent than CO2 as a Green House Gas.  Not to mention the pure arrogance of being able to throw away food when over a billion people across the world don’t know where their next meal is coming from.  It makes me feel sick and sad.

So if this issue is so big, what are some of the solutions?  Well a few that I can thing of that can help you to divert food waste from landfill are really common sense and easy to implement   The most obvious is to reduce food waste at the start of the cycle.  By this, I mean when you go grocery shopping.  Here are a few tips;

  • Take a list.  By using a list you will most probably only buy the food items you really need, and in compiling the list you would have checked upon your existing stores at home and just be topping up.
  • Don’t shop on an empty stomach.  From personal experience, you buy more food when you are hungry, and usually it is food that you just don’t need.  It is like impulse buying that kicks in due to hunger pains.
  • Grow your own food.  Plant a vegetable garden and reap the rewards, financially, physically and mentally.  It has been proven that people that grow their own waste very little of their own produce.  Maybe it is pride, or the thought of all that effort you took from seed to table.
So by limiting food waste at the beginning of the cycle reduces waste overall. 
During the storage phase, there are other solutions to minimise waste.  Here are some thoughts that might help
  • Menu planning.  Planning each meal may sound a bit anal, but it helps you to utilise the food you have at hand.  Each item in your fridge (where most food spoils) will be accounted for and will usually be used before going furry.
  • Use the crisper.  Your fridge has different compartment for different types of food.  The crisper is the best place for fruit and vegetables and usually last at least two weeks longer than in other parts of the fridge.
  • Use stuff on hand.  Before you go opening another jar of jam, check to see if you have one already open in the fridge.  No use breaking the seal to find that you still have one that is three quarters full.

Finally, what to do with leftovers?  Leftovers are one of my favourite meals.  They can be put into containers and frozen for lunches during the week.  They can be used in other meals.  Cooked too many vegetables?  Try making a bubble and squeak.  Too much Christmas Ham?  Make a pea and ham soup, or freeze chunks of it for use in a few months time when you crave some hammy goodness.  Cooked too much soup?  Well freeze it so you can enjoy it later.  There are so many things you can do with leftover food. 

If worst comes to worst, at least your pets can enjoy a good feed, or maybe even the chickens can have a nosh up if you keep them.  Nothing goes to waste around here at my house.  If the dog won’t eat it, the chooks, or worms or compost bins probably will.  The only organic things we throw into the landfill bin are small bones, but only after we have used them to make a stock!

In summary, using some of these methods will help you to reduce your organic waste, and save you a few dollars in the process.  Waste not, want not!
