How would you deal with food waste on a personal level, and what other action should be taken from businesses in order to reduce food waste? Do you have any tips you use? I can't see any more food expiring in my fridge, it's a huge waste of resources.
When it comes to things that are perishable, I don't stock up a ton. For example, instead of buying a ton of apples, maybe just buy 2 or 3. I have a lot of stock of canned foods and things like that, but apples as you mentioned, or things like bread and milk, I don't buy a ton of them instead opting to make more trips to the grocery store. I hate throwing away food, and I'm also not a huge fan of trips to the grocery store, but I think if you are only there to grab a few things it isn't so bad. Just starting thinking quality over quantity with your trips to the grocery store. Maybe that super pack of potatoes is a great deal, but maybe you really only need 2 for dinner and not 40 for the next couple months.
The issue is that even then, I just tuck them away in the fridge, never to be seen again. But generally, I try to be frugal and not purchase in huge quantities or buy products in large packaging, because most of the time, it'll simply go bad before it's consumed. I'm trying to limit junk food by switching to salads and fruits. Chocolates, chips, or bars because they are nutritionally worthless. They only provide you with a sugar boost, and that's it. Not only that, but a bag of chips costs something like €1.50-€1.50 and is consumed in a matter of minutes. I'd rather buy a few apples or bananas that'll get me going for a day or two.
We go to the supermarket for groceries 2-4 times per week
That seems a bit excessive... once a week is the best I can manage
As far as advice, I don't think there is any magic in it, just takes a bit of planning and discipline - track what you typically consume and buy only as much perishable food as you will need until the next trip to the store. I also found that having a large freezer is a good tradeoff - it costs money to run but it can save a few trips to the grocery store and many fresh perishable items can be frozen without significant loss in nutritional value, so it helps reduce waste.
I wonder if you've noticed cultural differences in food waste. Where I come from, throwing food away is very frowned upon. We prepare only as much food as we need; we put only as much on our plates as we'll eat; and if leftovers happen we eat it the next day. Lots of people around us seem to think that's weird and that leaving half of the food on the plate is some sort of sign of wealth ("I can afford it"). To each their own I guess.
Hmm, maybe I'm over exaggerating, but it's at least 2 times per week, maybe even 3. I tend to purchase only a few things at once, those that I only currently need. Knowing myself (and my girlfriend) if we buy a ton of food, there's a good chance that some of it will end up in the bin. I don't have the tendency to leave food on my plate, but once in a while, there will be leftovers that'll be forgotten about and thrown away. It's sad.
