Soil Injection

Soil Injection technology collects organic liquid residuals from food and beverage manufacturers and recycles it into nutrient-rich fertiliser for agriculture by injecting it directly into the soil. Increase your sustainability rates with a true end-to-end recycling solution for organic waste that results in zero waste to landfill.

Why Soil Injection?

Soil Injection maximises the nutrient value of organic by-products by collecting and treating the biosolids without exposing them directly to the air. This method preserves the valuable nitrogen and phosphorous in the organic material that leads to stronger, healthier crops.

The combined benefits create the triple bottom line of sustainability:

Economic benefit by taking large volumes of by-products and converting to cost-effective fertiliser
Environmental benefit by reducing greenhouse gases and improving landfill diversion.
Social benefit by supporting the local agricultural industry.

Benefit to the food and beverage manufacturing industry

Businesses that generate organic by-products can reduce their carbon footprint and improve landfill diversion rates by contributing the biosolids to a genuine closed loop recycling solution.

Cleanaway vehicles can inject 20,000 litres in just three minutes, offering a highly scalable service that can support volumes of any size. Unlike co-digestion, composting or piggeries, which can be limited in the volume of biosolids they can take.

Businesses would also see the cost of their general waste service reduce, by removing wet, heavy organic matter from their general waste bin.

Benefit to agriculture

Injecting liquid fertiliser into the soil maximises nutrient value and increases water retention, producing high quality crop and animal feed. Cattle fed on crops grown in soil injected pastures are healthy, with excellent frame scores and marbling content

Soil Injection also reduces the amount of inorganic fertiliser required over time and the ecological impact of farming activities. Because it is inserted as deep as 30cm into the ground, gasses produced by the fertiliser like methane and nitrous oxide (which are also greenhouse agents) is trapped within the soil, contributing as an ameliorant.

Composting, for example, is an aerobic process which releases methane and carbon dioxide into the atmosphere, losing nutrients during its breakdown.

How does it work?

We collect organic by-products from food and beverage manufacturers and transport them to pasture sites with our fleet of purpose-built vehicles. The organic material collected is stored on site in bulk storage tanks to be assessed and readied for application.

The organic by-product is then transferred to specialised agricultural equipment and injected below the soil surface to an approximate depth of 10 to 30cm. The paddocks are then ploughed to ensure the product is incorporated into the topsoil layer. This process allows the nutrients to be extracted from organic product and returned to the soil.

Eligible organic by-products

A range of liquid by-products are accepted including:

  • Dairy, ice-cream and yogurt sludge
  • Food waste from product destructions(out-of-date foods and beverages such as juice, soft drink and alcohol)
  • Flavouring, sauces and pastes
  • Waste water from the alcoholic beverage run off
  • Liquid waste from the vegetable and fruit canning process

Materials must be biodegradable (from food sources only), free from contamination and hazardous substances, and physically pumpable (typically 10% solid content).

Why choose Cleanaway

Cleanaway has a long and proven history of supporting industry and the community within established guidelines having worked with the authorities to help establish them. We are the only EPA licensed operator in Victoria with a fleet of purpose-built trucks for collection and application

Cleanaway also partners with universities to research other applications for organic by-products including its use as soil ameliorant and in biosolids land application.

Cleanaway has Australia's largest network of strategically-placed collection, storage and processing facilities, providing a product and service that is truly a closed loop, giving our customers the peace of mind that their waste gets a new lease on life.
