Globally, we are acknowledging the benefits of sustainable living. From the clothes we wear each day, to the food we eat. Both consumer and producer are more aware than ever on the effects their products make to the world around them. Companies are constantly striving to help positively impact the planet rather than destroy it for profit. One of the ways the food industry is doing this, it by focusing on innovative uses for their food waste.
Prime examples of the industry giants taking their step in the battle of food waste is how Tesco and Sainsburys are working to take volumes of food waste from their shops and either give it to charities or turn the inedible waste into fuel for their delivery lorries and animal food.
While these are big wins, there are also food waste innovators that have made their own huge leaps to reduce the waste they are producing. Here are some of our favourites:
Coffee shops have been striving to be more sustainable for a while now. From attempting to reduce the amount of single-use coffee cups to eradicating plastic straws – brands are now turning their attention to food waste, and Bio Bean is no exception.
The company was founded by a student who recognised the potential of coffee grounds used as a fuel resource. The process involved the wet coffee grounds being sieved, dried and compressed to make carbon-neutral soil biofuels – these fuels can be burnt to provide heat energy.
Further North of us you’ll find the six regions of whisky. Amongst these regions is a company looking to make their whisky production more sustainable for our planet – and they’ve been mastering it for years! On average, the two billion bottles of whiskey that are made each year leaves behind 500,000 tonnes of waste.
What Celtic Renewables has discovered is the ability to turn this waste from whiskey production into biofuel biobutanol. They have perfected the process of combining this with petrol for use in cars, as an attempt to lower carbon emissions. This waste can also be converted into ethanol, a chemical which can be used in alcohol production, bringing the product life cycle full-circle. Any soil material remaining from the conversion can be used for animal and livestock feed too.
All hail Nestlé! Their KitKat manufacturers have mastered the use – or reuse in this case – of their own product. If you have ever had the pleasure of biting into a KitKat, you will be well aware of the layer of creamy filling that resides in-between the small wafer slices.
Well, that thin creamy layer is actually from former KitKats. Yes, you don’t need to re-read that sentence. During the manufacturing process, any broken KitKats are collected and re-worked to make the filling in other KitKats. Simple!
Let’s all cheers to this great idea! Did you know that bread is at the top of the list for THE most wasted household food? It’s been estimated that around 900,000 tonnes of bread is wasted – in calories, that’s the equivalent of being able to take about 26 million people out of hunger poverty.
What Toast Ale does is take bread waste from sandwich shops and bakeries to turn into own-brew craft beer. The money they make from this also goes to further helping the UK’s food waste issue as they donate to Feedback – a food waste charity.
