Episode notes
Food Waste's Huge Emissions Impact
- Food waste contributes roughly 14-16% of global greenhouse gas emissions, mainly due to methane from decomposing food in landfills.
- This includes emissions from food production, transportation, refrigeration, and disposal processes.
Challenges in Home Composting
- Even committed environmentalist households struggle with food scrap disposal due to fruit fly infestations and inconvenience.
- Some people resort to freezing scraps or traveling long distances to compost drop-off sites.
Mill Turns Waste Into Chicken Feed
- Mill is an odorless kitchen appliance that dries and grinds food waste, shrinking it to stable, mail-able grounds.
- These grounds are sent back and upcycled primarily into climate-friendly chicken feed, closing the food loop.
