The Burleigh Heads Founder Turning Kitchen Waste Into Working Capital

Mia Sorensen started Groundloop in a shed behind her Burleigh Heads townhouse eighteen months ago with $12,000 in personal savings and a spreadsheet of cafés on the Gold Coast Highway willing to divert their food scraps. By June 2026 the company was processing 4.2 tonnes of organic waste per week, paying six small-scale producers across the Hinterland a collection fee, and selling finished compost to domestic gardeners for $18 a bag through a weekly pickup point at the Burleigh Farmers Market.

The timing is not accidental. Australians are watching grocery bills with an intensity not seen since 2022. The Reserve Bank's most recent household expenditure data puts weekly food costs for a Gold Coast family of four at roughly $340, up 23 percent over three years. Every dollar a restaurateur shaves off waste disposal feeds directly into menu pricing — or, in theory, keeps it from rising further. Sorensen built Groundloop around that arithmetic.

The company charges participating venues a flat monthly subscription of $290, below the $380-plus that Gold Coast City Council's standard commercial waste stream typically costs a café of comparable volume, according to council rate schedules published in February 2026. In return, Groundloop collects food scraps five days a week and guarantees zero landfill diversion for the material.

From Broadbeach to Tamborine: How the Network Actually Works

Groundloop's client list runs from Broadbeach's busy dining strip along Surf Parade down to smaller breakfast venues in Palm Beach. The scraps move inland three times a week in a refrigerated van — leased, not owned, which kept Sorensen's capital requirements low in the startup phase — to three farms on the Tamborine Mountain plateau and two properties near Canungra. The producers blend the organic material with locally sourced horse manure and run it through an eighteen-week hot-composting cycle before Groundloop buys it back at $4.20 per kilogram wholesale.

That buy-back arrangement is what makes the model genuinely novel on the Gold Coast. Most food-waste programs treat the producer as a service recipient. Sorensen structured her contracts so the farmers carry the composting risk but earn a predictable income stream — one Canungra producer told a regional agricultural newsletter in May 2026 that the arrangement added roughly $800 a month to what had been an erratic revenue picture.

Groundloop is not alone in this space nationally, but it is the only registered operator of this type currently listed with the Gold Coast Chamber of Commerce's sustainability business directory. The broader backdrop matters here too: Queensland's Container Exchange program, which keeps recycling depots operational despite ongoing safety reviews, has normalised the idea that waste infrastructure can be commercially viable rather than purely a council cost centre. Sorensen says that shift in public attitude made her pitch to investors easier.

What Consumers and Businesses Can Actually Do Now

Sorensen is raising a second round of funding — she is seeking $380,000 and has term sheets from two Brisbane-based impact investors, with close expected by September 2026. The capital would fund a second collection van and extend the subscription network to Southport and Hope Island, where she says five venues have already signed letters of intent.

For Gold Coast residents feeling squeezed, the practical entry point is modest. A Groundloop household compost subscription, trialled quietly in the Burleigh Heads and Miami postcodes since April, costs $9 a fortnight for fortnightly collection of a five-litre caddy. That buys participants a 20 percent discount on bagged compost at the Burleigh Farmers Market — a small offset, but a real one.

For food businesses, Sorensen recommends requesting a waste audit before signing any contract. She offers them free through Groundloop as a sales tool, but several Gold Coast sustainability consultants provide independent versions. The audit typically identifies between 15 and 30 percent cost savings in the first twelve months, based on comparable programs run in Brisbane's inner south since 2024. On the Gold Coast, where thin hospitality margins are a perpetual conversation, that number is worth taking seriously.
