Photo Blog: “The ‘Porta-Poster’ appears to be the ‘way to go’…”

Composting Bathroom

How far will you go to be more environmentally conscious? Many individuals and organizations are making efforts to reduce, reuse and recycle, but what about when it comes to a more private matter? Ben. G. of Ajna Projects and Designs specializes in composting toilets and worm bins, so when an outdoor education center wanted an eco-friendly restroom facility onsite, Ben was just the person to design it. He used some supplies from FarmTek for the structure itself and shared the outcome with us:

This is an accessible composting outhouse we made using 8 mil Twin-Wall Polycarbonate for roofing. The roof is able to withstand the snow load of New England winters while providing ample light to the room without using windows—which means greater privacy for the user. It’s also much lighter than other roofing options and faster to apply.

For rigidity, I framed it with the Twin-Wall Aluminum U-Profile edging and fastened it down with 1-1/4” pan head screws over FarmTek’s 1” Neo-Bonded Galvanized Washers. The 6’ by 8’ sheet fit the design seamlessly.

For those interested, this is a zero site-discharge, urine-diverting batch toilet that sequesters solids in one of two interchangeable sealed drums that have been configured for composting “humanure.” The urine will be reclaimed via a specifically designed seat and urinal for the agricultural nutrients. The solids drums will be swapped out every other season.

There is a need for low-cost ecological toilets in place likes farm stands and some of our local agricultural festivals. This “Porta-Poster” appears to be the “way to go” for these sites!

With a bit of resourcefulness, people can come up with great ways to preserve our natural resources and prevent pollution and waste.

What are you doing at your home or business to make things more eco-friendly?
