Victoria is putting more effort into keeping useful soil out of landfill. For home gardeners, that raises a fair question about where their garden soil comes from.

Soil reuse is moving up Victoria’s agenda. In May 2026, a new soil washing plant opened in Victoria to clean contaminated soil from construction and infrastructure projects so it can be used again. The facility was backed by a $1.15 million grant from Sustainability Victoria’s Circular Economy Infrastructure Fund.

The Victorian Government’s own circular economy market report notes that on smaller construction projects, mixed loads are still often sent straight to landfill, keeping demand for newly quarried material high.

Most of that activity happens far from the backyard. But the same idea, treating soil as a resource rather than rubbish, can also shape the products homeowners buy in bags and bulk loads every spring.

A supplier that works both ends

Melbourne supplier Soilworx sits on both sides of the soil story. On the construction side, it offers soil recycling, soil disposal and on site soil amelioration services. On the retail side, it sells garden soil and soil blends to homeowners from its yards in Deer Park, Pakenham and Werribee.

The company says it works to reduce waste, conserve natural resources and provide sustainable solutions across construction, landscaping and environmental work, on the basis that there is only one planet.

What recycled content means for gardeners

Recycled and environmentally friendly material is a good thing, but it comes with a trade off that honest suppliers state up front. On its Veggie Mix Soil, for example, Soilworx notes that because the blend is a recycled material, small fragments of stone, plastic, glass or rubble may occasionally be present.

That is worth knowing before you buy any soil blend. It does not make a product unsuitable, but it does mean checking the product description and asking the supplier directly what goes into a blend.

Matching the soil to the job

Soilworx sells its garden soils under the EcoActiv brand and positions each blend for a different use. The company says its range covers everything from trees and shrubs to veggies. Lawn Mix is a fine grain blend with moderate to low organic matter, designed for drainage and stability under lawns. Mushroom Compost and Organic Soil Improver sit in its soil improver and compost range.

The point is that garden soil is not one product. Choosing the blend made for the job means less waste, because you are not buying the wrong material and replacing it later.

Ordering with less waste

A few simple habits keep soil out of the skip and money in the household budget.

• Measure before you order. Volume is length times width times depth, and Soilworx offers a free volume calculator on its website, including for circular, triangular and combined areas.
• Choose bulk for bigger jobs. Soilworx says bags suit small projects and limited storage, but bulk is generally better value on larger jobs because you pay for the soil alone, without the cost of bags.
• Combine deliveries. Ordering soil, mulch and stone for the same project in one load means fewer truck trips.
• Ask what is in the blend. A good supplier will explain the source and makeup of its soils and flag any known limitations.

Small choices, wider effect

Victoria’s soil reuse facilities work at industrial scale; the upgraded EarthSure plant alone can clean up to 160,000 tonnes a year. A backyard bed might need less than a cubic metre. But the principle is the same at both scales: use the right soil for the job, order only what you need and treat what is already in the ground as worth keeping.

With almost 40 years supplying sands, soils, gravels, mulches and pebbles across Victoria, Soilworx sells garden soil in bulk by the cubic metre and in 25 litre bags, with GPS tracked delivery or collection from any of its three yards.
