Why food waste?

Today, an estimated one-third of all the food produced in the world goes to waste. That’s equal to about 1.3 billion tons of fruits, vegetables, meat, dairy, seafood, and grains that either never leave the farm, get lost or spoiled during distribution, or are thrown away in hotels, grocery stores, restaurants, schools, or home kitchens. It could be enough calories to feed every undernourished person on the planet.1

Food waste is responsible for 6% of global greenhouse gas emissions.2

We are teaming up with investors, individuals, and organizations to raise money to fund the best food-waste idea through micro-grants that will allow the initiatives to validate their idea.

1.3 billion tons of food is wasted every year globally.

Swedish food waste by the numbers

In May 2020, Naturvårdsverket presented a new report, detailing food waste generated by grocery stores, agriculture, and fishing, grocery stores, food production industry, commercial kitchens, restaurants, and households. Swedes throw away roughly 1.3 million kilos of food per year, with an average of 133 kg kilos of food waste per person. You can read the full report here.

It’s clear that household food waste is one of the biggest sources of food waste generated, with a majority of the food ending up in the sink and not being turned into a refined product like biogas or biochar. We need new innovations and ideas to reduce, reuse and refine the food waste generated within these sectors, especially within households.

The secret formula of Stockholm

Stockholm is where your journey starts, but definitely not where it ends. Our vision is set on solving the food waste challenge on a global scale, but Stockholm is a great place to start, and here’s why.

The Food Waste Challenge is made possible by the support of Invest Stockholm, as part of their Impact Investments promoting entrepreneurship towards a green transition.
