Foam Important

Foam Important characteristics of BioFoam containing substrates were investigated. Research showed that the stability of BioFoam is comparable to that of fresh coconut and by adding a modified E-PLA with open cells the water retention (see infobox) can be adjusted. For pF curves see graph. It was also established that BioFoam granules are suitable as a filler when transporting perennials and bulbs (lily and phlox) and gave a better product than the current packaging (fig. 7). A test cultivation in a hydroculture gutter system with a variety of crops (pivots) and with BioFoam beads as a part of the substrate showed that the growth is fully comparable to a standard substrate. Up to 100% BioFoam was used as a substrate in a hydroculture application showing no loss of growth rate. At the end of life stage it offers the potential to retain the nutrients that are contained in the substrate (roots) by composting - nutrients that otherwise may become lost when using perlite or mineral wool. These opportunities are now further explored and invitations are open to growers to be among the first users to participate in the industrialisation and scaling up. This project was made possible under the umbrella of the BioBest programme enabled by the province of Gelderland with participation of Synprodo, Synbra Technology, WUR Food & Biobased Research and WUR Applied Plant-CSO.

Water retention curves comparing various BioFoam modifications under investigation, compared with traditional peat. Waterretention curves are used to show how much water a given substrate can hold at various suction forces. The amount of water a given substrate can hold and the force a plant has to apply to take it up is very important for the growth. This amount is measured in volume% and the suction force (or how easy it is for a plant to take up water) is measured with a water column. -10 cm corresponds with 1 kPa suction pressure. The graph clearly shows different water retention for the various substrates at the start of the experiment. By modifying BioFoam the water retention can be modified this way controlling the water uptake of the plants. The graph also shows that at the end of the experiment most substrates can be refilled to return to the starting amount of water. 36 bioplastics MAGAZINE [01/13] Vol. 8
