Building Institutional Memory for Research Projects – Why education is key to long-term change

Research Impact, especially as conceptualised in the Research Excellence Framework, is often seen as bounded within a clearly defined project timeframe. In this post, Ryan Nolan, discusses how the National Interdisciplinary Circular Economy Research (NICER) Programme, has developed an interdisciplinary and long-term approach to research impact by focusing on education and community building. The importance … Continued

We flush valuable nutrients down the toilet. Wasted wants to save them

Chances are you used a toilet at some point today, and you didn’t think much of it.

But if you used a port-a-potty, you probably did think about it. Maybe a lot. And it probably wasn’t pleasant.

“No one likes the port-a-potty,” said Brophy Tyree, co-founder and CEO of Wasted. “It’s embedded into a really antiquated operations and servicing industry and so there’s a chance to make all of that better.”

But Tyree, along with co-founders Thor Retzlaff and Taylor Zehren, wants to do more than just redesign the smelly plastic boxes. The company’s first order of business is to turn the waste from port-a-potties into fertilizers for farmers.

“Farmers have been applying manure and other forms of animal waste to farms for millennia,” Tyree said. “When you talk to a farmer, they completely understand the value proposition right away. You don’t need to educate them on the fact that what’s coming through our body is valuable and has nutrients, because that’s just the water that they swim in.”

Human waste contains plenty of nutrients, but urine appears to be the real gold mine. Urine contains a lot of nitrogen, phosphorus and potassium, and wastewater in cities contains enough of the nutrients to offset around 13% of global fertilizer demand, according to one study.

Today, human waste is used as a fertilizer in some places. King County in Washington sells a biosolids soil amendment to farmers and foresters, for instance, and Milwaukee sells Milorganite to farmers and homeowners. They’re excellent examples of the reuse of human waste, but those products emerge at the end of a traditional sewage treatment process, which is energy intensive and vulnerable to severe storms and flooding.

Wasted wants to eventually serve as a backup for traditional sewage systems or even a replacement, particularly in regions where sanitation systems are underdeveloped. But it’s starting with port-a-potties for a few reasons.
