What Our Clients say!
Erin
"I absolutely love it but the most exciting part is that I run an Airbnb in Joshua Tree, CA and I rent out Yurts. I was originally using composting toilets for my guests and you can imagine how much fun that was. All my Yurts have their own BIOGAS Flushing toilet!!"
PAUL POSTON
"I live off grid in rural Hawaii so the biogas with toilet attachment is perfect for my situation. For the last four years I have been using a traditional composting toilet so the upgrade to the biogas toilet has been awesome"
Rachel
