The Companion is a part of the official portland emergency plan

The Sewer Catastrophe Companion is now a part of the official Portland emergency plan!  This is all thanks to the great work of PHLUSH.

Our Sewer Catastrophe Companion was featured several months back on the excellent Discard Studies blog. Max Liboiron does excellent writing on waste, reminding people what it’s really about:

Update: Note to Mathew, call people, don’t just google companies.

I recently had the chance to sit down with Brent from Hyphae Design Lab in person.  Although they don’t say so on their website, they have extensive toilet experience and know exactly what they’re up to.  I look forward to hearing more about the project.       This could really set composting toilets back [...]

Tuning the Aeration of our Pile

We’ve built a compost pile that is designed to be minimally turned and composted in a vessel, so we’re using a blower to get air in, and we need to tune the aeration rate. Our first problem running aeration tests is to measure the effective aeration of our system. As detailed below, the New Alchemy [...]

Help Protei! Autonomous, oil-sopping sailbots

This is fairly off topic, but I had to cross post from my personal blog.. Protei is a project I whole heartedly support, and provide tiny bits of advice too. Cesar Harada has put together an incredible team, and with a little money it is going to happen. “We are developing Protei : a low-cost [...]

Earle Barnhart & Hilde Maingay on Sanitation Alternatives

We received a lovely e-mail from Earle & Hilde, who have been busy illustrating alternative urban sanitation systems that can solve Cape Cod, Massachusetts’ ongoing aquifer poisoning.  Great flow diagrams for nitrogen within different systems, these would be a great complement to any presentation on contemporary sanitation practices and the future of sanitation.
