How do you avoid wastage of food for standard 3?

Answer 1

First of all what is standard 3?

But if you are talking about saving food in general i can help.

Left overs like fruits and vegetables can be kept for a maximum 2 days and then simply what ever is left give to bird or make your own compost dig a hole a put it in, it is great for help flowers grow and your bin woun' get as full. Meat is different. you can only really keep it in the fridge for 1 day and then it will have to be thrown out. Don't give to the birds they don't like meat, just make compost hole again or put in the bin but making yyour own compost hole is more eco friendly

I really enjoyed answering this question hope it is usefull to you.
