An eco-dining destination has set a precedent on the Coast for returning human waste directly to the soil.
Alsahwa Estate is the first venue on the Sunshine Coast to install a council-approved incinerator toilet.
The system requires no water, sewerage connection or chemical treatment. Human waste is reduced through high-temperature combustion to a small amount of sterile ash – roughly a tablespoon per use – which can be safely returned to the soil as a natural amendment.
Mayor Rosanna Natoli officiated the opening at the Palmwoods agritourism destination earlier this month, describing it as an example of innovation that could influence future infrastructure decisions on the Coast.
The process produces no waste to landfill and operates without the costly infrastructure normally associated with wastewater management, making it a potential option for parks, coastal reserves, beachfront amenities and other locations where sewerage connections are difficult or expensive to install.
The installation is the first of its kind approved for use at a destination venue in the region and forms part of Alsahwa’s broader ambition to operate as a closed-loop, off-grid business.
Alsahwa Estate has installed one unit, manufactured by Cinderella, with two more planned as part of the estate’s ongoing sustainability program.
The toilet complements a wider regenerative approach across the 30-acre property, which includes spray-free farming, on-site composting, recycled building materials and a farm-to-table dining model centred on produce grown on the estate and sourced from local farmers.
Mayor Natoli described the moment as an example of the kind of leadership that underpins our region and moves us forward.
“This is what great innovation and sustainability look like – showing governments and our community what’s possible,” she said.
“On behalf of Sunshine Coast Council, thank you for being the first. We’re sure you won’t be the last.”

Founder Jo Walker said the decision was entirely consistent with the vision she has held for the estate since the beginning.
“Alsahwa was built around a core belief: that true wellness begins with the soil,” she said.
“When the land heals, everything that grows from it does too.”
General manager Michelle Clark is keen for the milestone to be understood in its broader context.
“Every decision at Alsahwa asks the same question: does this heal or harm?” she said.
“The incinerator toilet isn’t a novelty – it’s one expression of a consistent philosophy we’ve applied at every stage of our estate’s development.
“Spray-free farming, composting into our new food forest, reclaimed timber, and now waste into ash returned to the soil. We want people to understand it as part of a pattern of intentional decisions that we hope others can learn from and build on.”
