To cook scraps can be a solution to reduce our food wastes. With our scraps, we can cook gratin, crumble, quiche, dumpling, soup,…
If you have eggs, flours and milk in your cupboard, you can make several recipes with your vegetables scraps.
Creamy vegetables crumble
It’s a crumble with different vegetables and you could choice different cheeses.

Vegetables stock cubes 2
Potatoes 2
Carrots 2
Parsnips 2
Leek 2
Sweetcorn 200g

Flour 110g
Butter 50g
Cheese to grated 100g
METHOD:
Preheat the oven to 220°C.
Preheat the oven to 220°C/425°F/Gas 7.
For 1 liter of water bring it to the boil. Crumble in the stock cubes.
Add potatoes and carrots. Then let to boil five minutes.
Add parsnips and leeks. Then let to boil t10/15 minutes.
Transfer vegetables to an ovenproof dish.
Scatter the sweetcorn over the vegetables.
Bring the cooking liquid to a boil, thicken with flour if necessary.
Crumble in the pan the cheese to form a sauce
Sift the flour, add the butter and rub it in with your fingertips until the mixture resembles breadcrumbs.
Add this crumble over the vegetables. Bake for 20–25 minutes until the crumble is golden.
It’s important to follow storage instructions, such as 'keep refrigerated' and 'store in a cool, dark place' and also any preparation or cooking instructions to be safe when you will eat your food.
If a product requires specific storage or preparation instructions, manufacturers have to include this information on the label.
Use a shopping list not to buy too much and control your purchase
There are two different types of dates on products :
A food product with a 'use-by' date must necessarily be eaten before the declared date, contrary to a food product with a 'best before' date !! In fact, for your health and safety, it's risky to eat expired food with a 'use by' date. But foods with 'best before' date are still safe to eat after the date (if they are not damaged and if you followed storage instructions such as 'keep refrigerated' and 'store in a cool, dark place'... ). The product with an expired 'best before' date may loose some quality (taste, texture, flavour, colour...)
Example of 'use-by' food : milk, meat...
Example of 'best before' food : cereals, biscuits, chocolate, sugar, flour...
-> Please, from now on, don't throw out every expired food !! But only food with an invalid 'use by' date.
We can save vegetable wastes to compost them in organic fertilizer. This compost can be used to fertilize fields or vegetable gardens.
Biomass digester is an alternative energy sources thanks to not edible food : this kind of food is used to produce gas and compost. The gas can be transformed in electricity. The compost is used for corn. It gives nitrate and other nutriments (like phosphate or potash) for plant growing.
The canteen wastes are recovered by a company who recycles wastes with a biomass digester.
-> Vegetables, starchy, bread, or other food which aren’t eaten by children can be transformed in electricity.
Food is crumbed and put in a biomass digester. After some weeks, wastes foods are transformed in methane gas and solid. Solid are saved by farmers to fertilize their crops. Methane is used to produce electricity with a transformator.
We can use wastes to produce a new type of snack :
N'Bread Process (New Bread Process) is a new French manufacturing process used to create new food for human people.
It allow you to transform some food wastes in a kind of ''bread''. This product is made of around 98% of original product and can be eated as a sandwich. This process uses only one additive which can be used in organic agriculture : we can make an 'organic waste bread'
A global issue
It is estimated that around 30 % of all food produced on the planet is throw out !! (around 1,3 billion tons), at the same time, 1 billion of people are hungry !
In 2009, Asians were the most wasters (see global map).
The biggest waster are people from Developed countries... (see next histogram). Indeed, in 2009, 28 % of food were lost or wasted by human consumption in Developed countries against 7 % in Developing Coutrines. It's mean, in Developed Countries, people throw out a lot of food at home.
About chemistry, Antoine Lavoisier said ''Nothing gets lost, nothing gets found, everything gets transformed''. This maxime could be used for food because food can be reused. Click to see the possible recycling :
It's essential to understand everybody have to act ! If you want to make your input to reduce food waste, click on advices :
- Don't make mistake between 'best-before' and 'use-by' dates'
