Gems of Innovation: Molly Winter of ReCode is legalizing composting toilets

Strict standards in health and sanitation codes can be some of the hardest regulatory barriers for innovators to overcome. For good reason, proper sanitation design and maintenance practices are essential to protect public health. In 2014, Molly Winter of ReCode worked with a stellar group of experts from 2020 Engineering, the Rich Earth Institute and others to legalize composting toilets the right way!

Strict standards in health and sanitation codes can be some of the hardest regulatory barriers for innovators to overcome.  For good reason, proper sanitation design and maintenance practices are essential to protect public health.  In 2014, Molly Winter of ReCode worked with a stellar group of experts from 2020 Engineering, the Rich Earth Institute and others to legalize composting toilets the right way!  They wrote a model national plumbing code for composting toilets with urine diversion which will soon be adopted into the IAPMO Green Supplement and published for use.  Instead of a prescriptive code, they wrote a performance-based code with field testing requirements to ensure proper sanitation.  You can read the 2014 draft code language here:

IAPMO (www.iapmo.org) is the International Association of Plumbing and Mechanical Officials, the group that writes and maintains codes and standards for plumbing systems.  The NW EcoBuilding Guild is anxious to work with Molly, IAPMO and her colleagues to publish details about this new model code, plus case studies of toilets approved through the new standard in 2016.  You can underwrite one or more case studies around this topic in 2016!
