Zynnovation LLC is a green technology and biotechnology company developing products based on green technologies and biomedical technologies. Currently, the firm is focused on research and development of green roof, bio- and chemical sensor, novel green processing technology, medical devices targeting diabetic patients, pollution prevention/control, recycling technologies, system design and optimization, surface science, adhesion and adhesives, polymer welding, and coatings. Zynnovationâs latest project involves the recycling of used disposable diapers into green roof materials using simple processing technologies. Disposable diapers are the most disposed household product in North America and account for about four million tons solid waste annually. Currently, only a negligible percentage of them are recycled. Conventional recycling separates and purifies each component of a waste material for subsequent applications, where higher purity is associated with higher value. For the after-consumer disposable diapers, however, it is not profitable to recycle in this manner because of their complexity. The associated economic and social benefits of this project include reductions in energy consumption, greenhouse gas emissions, solid waste, and a decrease in the urban heat island effect, as well as habitat and biodiversity preservation, and stormwater retention, horticultural lightweight growth medium, erosion control products, and growth medium for arid/semiarid areas
