Eco-Friendly 3D Substrates from Recycled Raw Materials
The choice of substrate for agricultural applications is crucial to ensure optimal growth of the crops. For instance, peat has traditionally used as a growing medium to produce crops due to its fertility and ability to provide the necessary conditions to support growth. However, peatlands are running out and unable to cope with the global demand for increased food, hence there is a need to seek for sustainable alternative substrates.
The technology is a three-dimensional (3D) dry but wettable substrate formed through the chemical reaction between natural substances such as clay, humus, and polysaccharides to form a matrix and incorporated with cellulosic fibers. The cellulose fibers can be derived from several waste streams including wood, coconut, straw, and bamboo to name a few. The 3D substrates can be customisable according to the type of crop and is biodegradable and compostable, releasing beneficial substances for soil and microflora at the end-of-life cycle. It has been successfully tested as a growing medium for fungi (Lentinula spp), lettuce, corn, and wheat. This technology is cost-effective and suitable for the vertical farming sector. It may also be extended to bioremediation applications.
