Toilets Can Be Beautiful

Circular & Sustainable Design

At Point of Shift, we envision a greener world where all bio-waste is valued and utilized in circular systems through beautifully designed, sustainable toilets.


We assist clients through each stage of the design and implementation process for sustainable, off-grid toilets, including the vision, goals, treatment options, permitting, and funding.


We love to talk toilets, so get in touch and let’s get started!

An Example

In September of 2021, Point of Shift built the first circular toilet at Stonehedge Gardens, an eco-village and wellness hub in Tamaqua, Pennslyvania. The waste from this toilet (food scraps, feces, urine, and menstrual blood) is composted for 6 months before being vermicomposted (enriched by worms) to create dark, nutrient-rich soil for the eco-village’s gardens.

What is

An alternative to traditional septic tanks and toilets, circular sanitation is the process of treating human waste with other bio-waste (food scraps, agricultural waste, etc.) and converting it into compost, water, and energy. It strengthens cities, communities, and businesses by providing local, renewable resources that increase as populations grow and businesses scale.

Recycling excrement may sound unconventional and unhygienic, but it is increasingly being recognised as an important step in circular sanitation and economy – a process of treating and converting waste into a usable product.


“This topic is super-hot right now,” says Kelsey McWilliams, founder and managing director of Point of Shift, a Philadelphia-based company that designs circular sanitation systems. “People are realising that what we’re doing is unsustainable, so there’s a lot more interest in circular sanitation, specifically in the US, but other places too.”


When done correctly, it is a more holistic and sustainable way of dealing with the worldwide human waste problem. Because the stinky truth is that our planet indeed suffers from a human poo overload.
