Our Future Depends on Reducing Food Waste

The future of our planet depends on being able to feed our growing population, while at the same time, the food industry is a significant contributor to climate change. Reducing food waste is an enormous opportunity to address both food insecurity and mitigate climate change, and it is among the many issues that need to be addressed in order to ensure sustainable food chains for future generations. In the spirit of Hellmann’s brand purpose – “make taste, not waste,” brand representatives and industry experts discuss how food companies can empower consumers to limit the waste, how technology and innovation are bringing new solutions and ideas for the future.

Harry Tannenbaum - Mill

Harry Tannenbaum – Founder and President of Mill

Harry Tannenbaum is the President and co-founder of Mill, where he’s built an entirely new system to prevent waste, starting with food. Mill is a practical and impactful way to take steps at home that are good for your kitchen and our planet. Mill’s approach recycles the food you can’t eat at home, conserves the nutrients, and sends it back to farms as food for chickens.

Prior to Mill, Harry led the centralized analytics group and ecommerce business at Nest, which launched the first learning thermostat and became the leading brand for the connected home. During his time at Nest, Harry helped to scale the business to more than $1B in annual revenue. Following Nest’s acquisition by Google, he was a director in Google’s hardware organization focused on ecommerce and subscription offerings. Before Nest, Harry briefly worked at an investment bank, before deciding he wanted to work in climate.

He received his bachelor’s degree in Economics from UCLA. Harry is a surfer, and was raised in San Francisco.
