How Mars is greening pet food with bycatch and grain

Read the full story in GreenBiz.

The United States is home to 85.8 million cats and 77.8 million dogs. They all have to eat. And that’s a problem — particularly when owners decide to feed their pets as if they were people.

The environmental impact of pet food is big, although no one knows just how big. Like the rest of us, dogs and cats consume meat, fish, corn and wheat, thus creating pressures on the global food system, along with carbon emissions as the food is manufactured and transported.

What we do know is that pet food is big business, generating about $22 billion in sales a year, industry groups estimate.

Much could be done to “green” pet foods — dogs and cats are getting more meat and fish than they need, for starters — but the industry is just starting to grapple with its sustainability issues.
