Waste-based manufactured soil constitutes the majority of growing media sold throughout South-East Queensland today. These soils use significant levels of composted recycled industrial and green waste materials as a so-called ‘organic’ base. The near composted components are then blended with different mineral elements such as topsoil, sand but mainly site soil to manufacture landscape soils designed with the intention of meeting the Australian Standard (AS-4419:2018).
The use of waste material is an environmentally sensitive means to recycle otherwise unused products. However, often soils are manufactured to suit the waste that is available in abundance rather than what best satisfies a plants requirements. Centenary Landscaping Supplies acknowledges that green waste blended landscaping soils are a sustainable and effective method for handling and processing this waste.
