The new landfill levy in Queensland will facilitate increased organic recycling activities, and consequently also the production of recycled organic products. With urban amenity markets (landscaping, soil blending) becoming saturated, compost producers are starting to supply also agricultural and horticultural markets. However, producers of root crops such as potatoes or carrots are reluctant to use urban derived composts due to fears that physical impurities (e.g. metal, glass) could become encapsulated in their produce.

This project will seek to clarify whether this fear is justified or not. Pot trials with compost that contains increasing levels of physical impurities will be used to assess whether and at what concentration physical impurities can become encapsulated in horticultural root crops.
