About your urine-diverting toilet, no longer called Ekologen:
It likely was not installed ideally.

We've sold many of these with our instructions for installation.

The only ones that have had owners complaining about odor had two things
going on:
1. It was installed with the urine drain line running horizontal for quite
a ways, resulting in pooling of urine.
2. They had very strong fans in the bathroom, which pulled odor from both
the urine drain and the solids container/composter.

Occasionally, there is clogging due to the first factor.

Also, one customer had a large 50-gallon urine tank on a 20-inch urine
drain line. That's a lot of potential orodr.

One customer who had strong fans in the house installed a P-trap in the
urine line.

Note that these issues also are reported with urinals, both waterless and
flush.

Also check the composition of the drain hose. Some plastics really hold
odor and corrugated plastic definitely will. Get smooth-wall hose made for
this.

Because of installation issues, the manufacturer now sells them with odor
filters in the urine drains.
EcoTech Products is the supplier in North America.

Urine separation is interesting. The solar folks who share an office with
me have all sorts of DIY urine-div toilets, pretty basic. There usually is
no odor. The fan is just on the solids container. I think our fan intake
balance is good there.
