SEOUL, Nov. 19 (UPI) -- Japan will set guidelines to collect and recycle disposable adult diapers as its population ages rapidly.
Japanese environment authorities will distribute recycling guidelines for disposable adult diapers to municipal governments as part of the efforts to reduce growing diaper waste, Yomiuri Shimbun reported Monday.
The guideline will introduce some latest technologies, including the one that transforms diaper waste into fuel.
In 2015, a town of Hoki in Tottori Prefecture began to collect disposable diapers from hospitals and nursing homes to have them recycled. The diapers are broken into pieces and then dried with hot air and converted into pellets that can be used as fuel, according to the Japan Times.
A recycling firm also recycles some 5,000 tons of disposable diapers annually by extracting pulp and converting them into construction materials, according to Yomiuri.
In Japan, the elderly population aged 65 and above account for 27 percent of the total population, according to a World Bank figure in 2017. The number of elderly people aged 75 or older has been on a rapid rise with the average increasing rate of 30,000 every month, according to Nikkei Asian Review.
As the population ages quickly, the country has seen a rapid increase in the volume of disposable adult diaper waste. The amount for disposable adult diaper wastes surged from 840,000 tons to 1.4 million tons from 2007 to 2017, according to a group promoting paper diaper recycling.
Disposing of the diaper waste has emerged as a new environmental concern in rural areas where adult diapers consist of 20 to 30 percent of total wastes.
Adult diapers pose a challenge in the disposal process because they are wet and heavier than baby diapers, which makes them difficult to burn.
