As a society we’ve grown disturbingly accustomed to wasting resources and destroying our fragile planet. Hundreds of trillions of gallons of water are wasted globally in food production alone, an unfathomable number to the average person. And yet the water we use to drink, bathe in, shower in, and flush the toilet with, accounts for less than one per cent of the world’s overall supply. In a century where the global population is expected to surpass nine billion, it’s never been more critical to manage our use of resources and limit waste.
We’re all guilty of wasting food but not all of us are aware of the dire impact this is having on the environment. Landfills of rotting, wasted food are potent sources of methane - a greenhouse gas with the potential to accelerate climate change even faster than carbon dioxide. A reduction in food wastage would also mean a reduction in the emission of greenhouse gases in general, as the environment-harming chemicals associated with the production of food will be lessened.
So what can we do to reduce food waste?
Planning meals in advance
Efficiency and management is the key. At the supermarket, try to shop with a list, reducing impulsive purchases. A weekly planning schedule could help, giving you an idea of what to prepare and when. In time, you’ll develop a knack for portion sizes, and will learn what’s right for you and others, you may even find you’ve overspent in the past, making your weekly shop more cost effective.
Getting creative with leftovers
As much as proper planning can help, leftovers are unfortunately more or less an inevitability. Freezing anything that is left over can preserve it for months. Canning, pickling and drying are three effective ways of ensuring your food goes further. The Love Food Hate Waste website is an invaluable resource - it is full of unorthodox, underrated and underappreciated cooking techniques and recipes that can help you create something delicious from what you would otherwise assume are incompatible ingredients.
Invest in a wilo central heating pump
While it won’t technically reduce the amount of food waste you generate, a wilo central heating pump will help to reduce the guilt you’ll feel after hearing the following statistic: throwing away a single burger wastes the same amount of water as running a shower for an hour and-a-half. Whenever food is wasted, so too is a mass of water.
These ingenious central heating circulator units from Wilo regulate and maintain the water temperature in pipes even if they aren’t located near the storage tank or boiler. Although some initial energy is expended maintaining a uniform temperature, in the long term you can expect a drastic reduction in both consumption and wastage. After all, there’s no need heat up the water if it’s already at a desirable temperature, and you’ll no longer have to let the water ‘run’ as you turn on the tap - because it’ll already be hot.
