Whilst we are all becoming more aware of the amount of food that gets wasted every day around the world, have you stopped to consider the energy it took to produce all that food that is going in the bin?
A huge amount of energy is needed grow, pack, transport and distribute food items that will end up as rubbish or compost – especially when you realise almost 40% of UK food products end up in landfill sites. Not only are we wasting food and finite resources, but the rotting waste in landfill releases harmful gases which contribute towards global climate change.
Reducing Energy Wastage
So where do we start? First up, minimising waste is the best way to maximise efficiency. While we may be thinking of ways to use renewable energy sources, what’s more important is reducing the amount of energy that we waste, and therefore use up, in the first place. There are so many ways to prevent food waste. From buying less to proper storage, from smaller portions to writing a shopping list. Any reductions in our food waste will in turn reduce energy waste.
Happily, food waste is increasingly being seen as a resource in its own right, with processes being developed around the world to turn food waste into energy. With the global demand for energy continuing to rise, and fossil fuel availability becoming worryingly low, this may be a promising solution to create much needed fuel and electricity.
If we can reduce the amount of food we waste and adopt ways of creating energy out of organic waste, we can hope to see pollution and energy waste decreasing on a large scale in the near future.
