This invention pertains to a bio-mass processing system, and method of processing waste bio-mass, wherein one or more mixers mixes a bed of bio-mass material such as manure at substantially any and all locations in a defined length and width portion of the bed, in a dryer. The active agents are contained in capsules having a capsule wall comprising an environment-induced material. On this basis a nursery infant-parent identifier system is provided whereby, when a detecting baby bracelet is brought into the presence of an identifying parent’s tag, a reliable indication is provided as to whether the bracelet and tag have been previously bonded. Such a fastener is advantageous because it offers the benefits of magnetic fasteners and is at the same time readily attachable to an article having strap ends with an existing pair of complementary engagement means.
