On the Catalyst with Shayle Kann podcast this week:
In the U.S. alone, food waste is responsible for the equivalent emissions from 42 coal power plants. Globally, it accounts for 10% of greenhouse gases, more than heavy industries such as the manufacturing of cement and steel.
Why? Wasted food means wasted energy. Throwing a piece of food in the trash is like tossing out the fertilizer and fuel used to make it, too. And we waste a lot of it. Nearly one-third of all food grown in the U.S. gets trashed. On top of that, when food decomposes in landfills through anaerobic digestion, it releases methane, a potent greenhouse gas.
So how do we clean up food waste?
Disclosure: Shayle’s venture capital firm Energy Impact Partners is an investor in Mill.
Matt and Shayle cover topics including:
Where food waste occurs along the value chain (hint: The biggest source of waste is us, when we toss food we’ve already purchased).
The causes of emissions, from energy inputs to anaerobic digestion in landfills.
The current solutions to food waste, such as composting, green-bin programs, supply-chain management software and shelf-life extension.
The challenges with landfills, including trucking waste and landfill capacity.
Mill’s new consumer-focused food waste technology, which includes shipping dehydrated food scraps in the mail.
How much consumers care about food waste and carbon emissions.
