01 / Why this can help

Your scenario, drawn

Cook the edible parts you usually set aside

Editable example inputs, not a measured or predicted saving.

Cook the edible parts you usually set asideBefore: 10.4 kg food; After: 5.2 kg food; Annual difference: -5.2 kg of edible food wastedIN ONE YEARBefore10.4 kg foodAfter5.2 kg food010.4 kg food

Same scale, starting at zero. Change the assumptions to compare the two annual totals.

02 / One possible next step

Begin with a familiar edible part, such as a peeled broccoli stalk, in a recipe you will eat.

Context-dependent outcome

What the evidence supports

Using suitable edible stalks or leaves can prevent food waste during preparation. The benefit occurs when those parts are actually eaten, as recommended in food-waste prevention guidance.

Boundary of the claim

Not every peel, leaf or stalk is edible. Identify the food correctly, prepare it safely and include any extra cooking. Do not convert every gram used into a universal carbon saving.

What this simulation calculates

The initial values are editable arithmetic examples, not measurements or typical savings from the cited studies. Replace them with comparable readings for your situation. The sources support the mechanism and its conditions; they do not predict these numbers.

Your illustrative scenario

Over one year · with the assumptions below

You

5.2 kg of edible food wasted less

You + 10 friends

57.2 kg of edible food wasted less

1,000 participants

5,200 kg of edible food wasted less

These are scenarios, not measured personal or collective savings. One separate household per participant. People sharing a home count it once, not once each.

Your inputs

Edible food discarded per week Before
0.2 kg food
Edible food discarded per week After
0.1 kg food
Comparable weeks per year
52

Calculation of the difference: (0.2 − 0.1) × 52 = 5.2 kg of edible food wasted

Calculation boundaries

Count only the specified material. This is not a life-cycle assessment and does not convert material into carbon, water quality or biodiversity benefits. Weigh edible material actually discarded for equivalent food provision. Fridge energy and extra cooking are not included. Not every peel, leaf or stalk is edible. Identify the food correctly, prepare it safely and include any extra cooking. Do not convert every gram used into a universal carbon saving.

The initial values are editable arithmetic examples, not measurements or typical savings from the cited studies. Replace them with comparable readings for your situation. The sources support the mechanism and its conditions; they do not predict these numbers.
