Your waste
Assumes loose waste at ~150 kg/m³, a 4-tonne elephant, a 42.6-tonne empty A320, ~0.6 kg CO₂e per kg landfilled food and 0.17 kg CO₂ per car-km. Illustrative only.
This is an illustrative planning estimate, not an audited footprint. Final results depend on vendors, menus, materials and venue practices.
The conventional waste journey
Mix
Food, packaging and décor share a bin.
Move
Contamination reduces recovery options.
Dispose
Buried organics can generate methane.
Food and other organic material in landfill breaks down without oxygen, producing methane—a powerful greenhouse gas.

tonnes of food waste generated in 2022
19%
of food available to consumers was wasted
60%
of that food waste came from households
The Zirow tree record
A living thank-you, tracked by name.
Qualifying Zirow events can include a named tree record. Once planting is verified, the record can show its species, location, planting date and latest field update.
Eligibility and planting timing are confirmed in each event proposal. A record is only published after Zirow receives planting evidence.
