Plastic vs food waste
There's sometimes a tradeoff between food waste and plastic packaging waste.
Examples
- Frozen vegetables (more packaging) vs fresh vegetables (more perishing)
- Individually portioned meals (more packaging per unit of food) vs large economic size (more likely to not finish all of it in time)
- ↑ Large format is probably more eco-friendly in this case, if you can make the effort to finish everything in time.
- At a restaurant or event: taking home leftover food "to go"
- ↑ Taking it "to go" is almost always better than letting the food go to waste, even if some extra packaging is involved. But if you can find a way to avoid both, then that's even better. Don't listen to peer pressure to leave before you're done eating everything.
Seeking a fair comparison
Popular eco-influencers have been focusing a lot on eliminating packaging and avoiding "processed" foods. But a perishable diet could potentially lead to more food waste overall, if people aren't careful. There needs to be more awareness and effort to avoid this.
Some things to note:
- Food waste is a major contributor to deforestation.
- Plastic is made from fossil fuels, but most packaging is fairly lightweight - more fossil fuels are burned just by shipping the food (even in a "local farmers' market" scenario).
- Plastic pollutes the oceans and other ecosystems, but maybe this depends on how it's disposed of? To what extent does throwing plastic in a regular garbage bin contribute to this? [RESEARCH needed]
Research needed: Math:
- Wasting a kilogram of plastic is equivalent to wasting how many kilograms of food, all things considered?
- Obviously this is a complex question that requires weighing a lot of different factors, and making somewhat arbitrary considerations. But we should at least try. Making a few rough estimates is better than having no answer at all.
What to do about it
- Make use of food before it goes bad
- There are some non-perishable foods that have a low packaging-to-food ratio. For example: Dried pasta, dried beans, flour, seasonings
