Worldwide, hospital waste — human and clinical — poses threat of contamination to hospital staff, patients and relatives.


Addressing this challenge, Pharmafilter BV, a Netherlands-based company has developed Pharmafilter — an integral zero waste hospital waste-water management process not requiring contact with contaminated waste.

The patented technology uses single use disposables made from biodegradable plastics made from corn, starch-based blends and replace conventional bedpans and urinals. The wastes are disposed of in a shredder named Tonto replacing bedpan washer, sanitizer.

Together with effluents from toilets, sinks and showers, the shredded waste is transported through the existing pipes to a purification plant set up in the hospital premises.

The solid waste separated from wastewater is reduced by anaerobic digestion producing biogas (Methane) utilised for powering the plant.

The waste water eliminated of all medicines, germs, cytostatics, contrast liquids and endocrine substances can be reused as process water.

Though some Indian hospitals tried versions of disposable bedpans, disposal of end product was found not eco-friendly.

“We are willing to test and adopt the Pharmafilter model provided it is viable both ecologically and financially according to Indian situation,” Saravjeet Kaur, director, nursing, Max Health Care told HT.
