Trelino Evo M Composting Toilet review
By Tom Calder
We no longer recommend this model, so it no longer appears in our buying guides. In its place, we now recommend TROBOLO WandaGO Composting Toilet in our Emergency toilets guide.

- Separating (composting) toilet

- —
Trelino made separating toilets mainstream: urine goes to a front canister, solids to a lined container with a scoop of cover material, and because the two never mix there's remarkably little smell — no water, no chemicals, no cassette chemistry. The Evo M is the compact size that suits a campervan, boat, garden office or as a serious household backup. It's a routine, not an appliance: the urine canister empties every day or two in use, solids weekly-ish, and it needs somewhere ventilated to live. For genuine off-grid capability it's the modern answer.
