Petra de Verdier
"I'm super happy! My daughter says it's just like using a regular toilet."
The architectural project manager and textile designer Petra de Verdier leaves nothing to chance when it comes to aesthetics. Her holiday home outside Gnesta is used year-round but has no blackwater drainage system—that is, no sewer connection for toilet waste. The house was based on a modular house that Petra redesigned together with Waldemarson Arkitekter to create a place where she could retreat and get away from the city. For her, a flush toilet was never an option. She wanted to make the most of the earth’s resources and keep the nutrients circulating on her own property.
When planning the bathroom, she looked at the waterless toilets available on the market but didn’t feel that any of them were right. “I just didn’t think they looked good. Before I found Luna, I was actually considering whether I could build another model into the bathroom furniture so it wouldn’t be visible. If I had chosen the same solution as my neighbour, who has a composting chamber beneath the house, I would have had to raise the house another 1.5 metres above ground level, and that simply wasn’t an option. Luna was the first toilet that both worked the way I wanted and looked like it belonged in the bathroom.”
Composting
"I even emty the bucket without a lid on, because it still feels fresh."
"The avocado pits take the longest to break down. At the moment, little avocado plants are sprouting in the compost."
Petra installed the very first Luna ever produced and was Harvest Moon’s test user during the development of the toilet. It had an aubergine-coloured lid at the time, chosen to harmonise with the tiled floor in the bathroom. Since then, features have been refined and the product has evolved into what it is today. “I’m really happy with it! Luna is quiet and doesn’t smell at all. I empty the bucket into a Roslags compost and use the nutrient-rich water to water the garden, which is incredibly convenient. For me, it’s important to reduce my environmental footprint as much as I can while also getting nutrient-rich water for the plants and, in time, rich soil.”
The property has two large composts that are used alternately. Food waste and toilet waste are mixed together, and after a few years the contents become soil created on the property itself.
New visitors are given a brief introduction. “The only thing you really need to think about is how you sit, so that the pee goes at the front and the faeces at the back. No one has had any problems with that, regardless of gender.” According to Petra, the most common misconception about waterless toilets concerns the smell. “Many people think they smell, but Luna doesn’t. I’ve recommended it to several friends because it looks good, works exactly as it should, and doesn’t smell at all.”
