About CompoCloset
CompoCloset was founded in 2020 during covid after the CEO, Richard, had been impressed by the composting toilet in his campervan, yet was also dissatisfied by it’s design.
CompoCloset was born with the belief that more people would use a composting toilet if they were better. Since learning of the Global Sanitation Crisis we still share that belief, but the scale of our mission and vision has changed.
