Renew provides a closed‑loop sanitation system that separates liquid and solid waste at the point of use, stabilizes urine, and composts solids into nutrient‑rich compost. The system eliminates odors, removes pathogens, and returns recovered nutrients to soil as fertilizer, offering a low‑cost, off‑grid alternative to conventional toilets.

Problem
Many off‑grid locations, mobile communities, and temporary event sites lack access to conventional sewage infrastructure, leading to costly waste disposal, environmental contamination, and loss of valuable nutrients. Traditional portable toilets often generate odor, require frequent servicing, and do not recover the nutrients contained in human waste.
Solution
Renew offers a closed‑loop compost toilet system that separates liquids and solids at the point of use. The urine is chemically stabilized to retain nitrogen, potassium, and phosphorus while eliminating odor, and the solid waste is mixed with a carbon‑rich cover and aerated to enable biological composting that destroys pathogens. After a short composting period, the resulting humus (humanure) and stabilized urine are ready to be returned to soil as fertilizer, turning waste into a usable agricultural input. The system is shipped ready for installation and is designed for use in RVs, public restrooms, event venues, and other locations without sewer connections.
Target Audience
Primary customers include RV owners, portable‑toilet operators, public restroom managers, and event producers who need a self‑contained, low‑maintenance sanitation solution for sites without sewer access.
