The content of carbon and water in food and its impact on the environment is not particularly well known, especially when it becomes waste.
Since 1970, Earth Day on April 22nd has served as a reminder of our collective responsibility towards the planet. It's a day that ignites passion and drives action, urging us to come together and pave the way for a sustainable and equitable world.
One impactful avenue for change lies in addressing food waste.
We all appreciate the pleasure of a delicious meal; food sustains us—it's vital for our growth, our lives, our very survival. Yet, the journey from farm to fork carries a significant environmental burden. When that food goes uneaten, the toll on our planet grows significantly.
The statistics are staggering: according to the World Wildlife Fund, 40% of all food grown worldwide goes to waste. That's a mind-boggling 133 billion pounds of food lost annually, equating to a monetary loss of $161.6 billion and a staggering 141 trillion calories lost. This waste not only drains our wallets but also places a heavy toll on our environment.
So, why does food waste matter?
Understanding the concepts of food waste and food loss is crucial:
Food Waste: This occurs when perfectly edible food is discarded, typically at the retail or consumption stages. Shockingly, 75% of food waste in the UK is considered entirely edible.
Food Loss: Unlike food waste, food loss happens earlier in the supply chain, before it reaches consumers. It's the result of spillage, spoilage, or loss during storage, packaging, or processing.
So, how can we take meaningful action?
The Food Waste Hierarchy is a framework that outlines a step-by-step approach to addressing food waste, prioritising actions to maximise impact:
-
Prevention: The most effective strategy is to prevent food waste from occurring in the first place. This involves better planning, smarter purchasing and proper storage practices.
-
Redistribution: Instead of throwing away surplus food, consider donating it to those in need. Food banks, shelters, and community organisations can help redistribute excess food to vulnerable populations.
-
Recycling: For food scraps that can't be prevented or redistributed, recycling is the next best option. Composting organic waste can divert it from landfills and produce nutrient-rich soil for gardens and agriculture.
-
Recovery: Some food waste can be salvaged through innovative technologies like anaerobic digestion or bioenergy production, converting organic matter into renewable energy sources.
-
Disposal: As a last resort, food waste should be disposed of responsibly, minimising its environmental impact through methods like landfill diversion or waste-to-energy facilities.
On this Earth Day, let's commit to combating food waste at every level of the supply chain. Together, we can turn the tide, preserve precious resources, and build a more sustainable future for generations to come.
