Matrix

The basic material floating islands are made from is a non-woven matrix, made from recycled polyester, a plastic, also referred to as a polymer. The plastic is extruded and spun. The matrix is supplied to us in layers, which we then shape and bond together with adhesive foam to create the family of floating island models. The open nature of the matrix allows plant roots to grow through it, yet it is dense enough to hold BioMix without leakage. Its fine network of “fibers” creates a huge surface area for colonisation by microbes (see BMQ).
