Every living organism consumes nutrients and creates waste. To transformwaste back to nutrients and complete this cycle, nature uses the processes of decompostition and evaporation. As is often the case, nature seems to be doing business in the best way possible.
That's why Sun-Mar toilets are designed not only to harness these natural processes, but to optimize and accelerate them. More...
SUN-MAR’s Garden Composters incorporate our patented double drum Autoflow® design. With Autoflow®, material goes in the top and compost exits out the end as the drum rotates. As the drum rotates, compost moves along the outer drum and then back through the inner drum before dropping from the output port. As the acknowledged leader in the field of composting toilets, we at SUN-MAR know that the best way to compost is to use a rotating drum. We have been using a rotating Bio-drum in our composting toilets for over 25 years! More..
