09/19 The Cell

If apples have fallen on the ground or are not up to standard the farmers throw them away, even though they are perfectly fine. After that, the apples are washed and waxed to look appealing to customers. During this step, apples are wasted if the they are ruined while waxing. Some apples are then processed into different food items, such as pie filling, apple sauce and more. If people mess up during this conversion, the apple product gets thrown away. Then, the apples are packaged.If packaged incorrectly, the apples get thrown away. After this step, the apples ge...
