Used Adult Diapers - The Latest BioFuel?
With innovative new biofuel conversion technology, used adult diapers become an energy source instead of a disposal problem
The world is experiencing an elder boom, and Japan, anticipating that 24% of its population will be 85 years or older 2030, is in the forefront of facing the accompanying issues - one of which is what to do with all the used adult diapers. Several methods are gaining traction in converting tons of used adult diapers into an energy source.
Super Faiths, a Tokyo firm, has manufactured a machine that turns used adult diapers into fuel. The SFD machine takes bags containing the used disposable diapers and automatically pulverizes, desiccates, and sterilizes them, reducing the trash to less than one-third of the weight and bulk of its original size. The pellets that result from the day-long process are odorless, bacteria free, and contain 5,000 kcal of heat per kilogram. The product can then be used in biomass boilers and stoves.
A western Tokyo hospital is processing 1,400 pounds of both adult diapers and children's diapers with the two SDF machines it has installed, thus preventing more than a ton of trash ending up in landfills every couple of days.
More on creating fuel from waste:
Another Japanese company, Total Care System of Fukuoka dissolves used adult diapers and children's diapers in a special solution, turning them into plastic and pulp suitable for use as a construction material and as solid fuel. Total Care has built a plant in Omuta, Japan that processes 14 tons of used diapers from hospitals and care facilities daily.
Frequently these days, bad news is accompanied by good news. Adults wearing diapers may be the wave of the future and a major challenge for society, but innovative green technology companies are quickly developing technological solutions for the disposal and conversion of the adult diapers into fuel sources.
