“ A lot of our waste here, and a lot of almost any city’ s waste, is actually food,” Gregory explains.“ So they said‘ let ' s take food waste, convert it to fertilizer and put it back into the system’.” ​
A Zimin Institute project was built around converting post-consumer food waste into a viable, cost-effective liquid fertilizer – a task complicated by food waste’ s typically low nitrogen content. The project was led by ASU Assistant Professor Yujin Park and conducted at her Indoor Farming Lab at ASU’ s Polytechnic campus.“ Most food waste isn’ t by itself a viable fertilizer, so her project focused on a novel processing method to inexpensively convert the food waste into a usable liquid fertilizer that would be viable and effective,” Gregory says.
The result was a breakthrough – Yujin and her team successfully developed and demonstrated this technology in her lab and then transitioned it to Homer Farms, who has since brought the product to market. ​ In recognition of her work, Yujin was awarded the prestigious New Innovator Award from the Foundation for Food and Agriculture Research in 2024.
The impact didn’ t stop at technology. The Zimin Institute’ s initial support was catalytic, positioning Homer Farms secure major funding from the City of Phoenix to create a 10,000 square-foot demonstration and pilot production site.“ I don’ t want the Zimin Institute to take credit for the Phoenix funding, but there’ s no doubt that our success with our project helped them demonstrate
