A waste-management company has developed a new, patented process that turns sanitary products, baby diapers, incontinence pads, and other so-called “absorbent hygiene products” into power. PHS Group, which serves 90,000 households, schools, offices, and retirement homes across the United Kingdom and Ireland, says that it handles about 45,000 tons of the stuff a year. A plant in the Midlands is currently converting 15 percent of that waste into compressed bales that can be burned to provide fuel for power stations.
Refuse-derived fuel is neither an untested concept in Europe, where the practice is par for the course, nor in the U.K., where it’s gaining ground. But diapers, tampons, and their ilk have proved trickier because their dampness makes incineration most costly. But neither is dumping them in the landfill, where they’ll take decades to degrade, a sustainable solution.
“Hygiene products are an essential part of many of our everyday lives but disposing of them has always been an issue,” Justin Tydeman, CEO of the PHS Group, told Guardian.
PHS Group’s system, which is being evaluated by the University of Birmingham for its effectiveness, not to mention its impact on the environment, sounds simple in principle.
The company begins by shredding and squeezing the material, then disposing of any waste liquid as sewage. The remaining dry material is packed into bales, ripe for tossing into the fire.
“Whether or not it turns out to be a major source of energy in itself, the key thing is we find a good way to handle what is a complex and growing waste stream,” Tydeman said. “We don’t want this stuff just going into the ground.”
An aging population makes PHS Group’s tack even more vital than ever, Tydeman added.
“The great thing about life today is people are living longer, but what comes with that is often incontinence issues,” he said. We want this to be a growing issue, because we want people to live longer.”
