Multi-departmentsolution
Filtering broad range of pharmaceutical residues from patient's urine.
For hospital departments where catheters, urinals and bedpans are frequently used and carry high concentrations of medication residues, e.g. ICU, Cathlab, Neurology.

The challenge
Bedbound care sends concentrated medicine loads straight to the sewer.
Care-intensive departments, such as ICUs, neurology wards etc., patients cannot use standard toilets. Urine collected via catheters, urinals and bedpans is emptied via e.g. bedpan washers or normal sinks. As a result, a broad range of medicines, like antibiotics, anesthetics, pain killers, enter sewages, municipal wastewater treatment plants and the environment. Ward teams need solutions that fit existing nursing routines — while hospitals need measurable evidence that emissions are being reduced.
Hidden ward emissions
Pharmaceutical loads are highest at ward level, yet this is rarely where interventions or monitoring take place.
Standard routines
In these departments, urine with high concentrations of medication residues is already collected through standard routines, such as catheter bags, bedpans and urinals.
AMR scrutiny
Growing concern around antimicrobial resistance and antibiotic residues in hospital wastewater. Reduction of antibiotic concentration is key.
Unused liquid medicines
Unused liquid medicine residues are often disposed of as costly clinical waste. With MediCatch, hospitals can process these liquid residues directly at the source, while empty packaging can be collected separately for appropriate waste handling or recycling.
The Zereau approach
Filter collected urine in the MediCatch Sink.
MediCatch processes the content of catheters, urinals, and bedpans without extra work for staff. Filtration is integrated in a dedicated sink staff uses to empty the contents.
The filtered urine is subsequently discharged through the system into the hospital sewer, free from pharmaceutical residues.
The system also processes unused liquid medications, allowing empty containers to be recycled or disposed of as regular waste.
System configurations
MediCatch Sinks configured for ICU's and other intensive hospital wards.
MediCatch sink
Installed in the soiled utility room, where urine and liquid waste streams are already handled. MediCatch adds filtration to existing workflows, enabling responsible treatment without extra work for staff.
- Handles catheters, urinals, bedpans and all other clear liquids.
- Serviceable filter cartridges.
- Sustainability built into the background, without adding work for staff or affecting the patient experience.
Ideal for ICU and high-dependency wards.
MediCatch in hospital pharmacy
Hospital pharmacies generate liquid waste from production, samples, and out-of-date medicines. These streams are often treated as costly medical waste. MediCatch filters residues at source — before they leave the prep area.
- Handles production rinses, samples, and expired liquid medicines
- Reduces medical waste volume and disposal costs
- Fits existing prep and disposal routines
Ideal for hospital pharmacy and aseptic preparation areas.

EANM 2026: Zereau at Booth 321 – hall X3. Is Our Infrastructure Ready for the Growth of Nuclear Medicine?
Next week, the nuclear medicine community comes together in Vienna for EANM’26. Radioligand therapy is expanding. New radiopharmaceuticals are moving through clinical development. Alpha therapies are gaining momentum. Patient access is increasing, and hospitals across Europe are preparing for further growth.

What hospitals say:
“The Netherlands scores poorly on surface water quality. Noordwest Ziekenhuisgroep acts by installing Zereau filters in multiple departments. They capture pharmaceuticals and antibiotics at the source, reduce strain on water authorities, and improve regional water quality.”
Noordwest Ziekenhuisgroep
Alkmaar, the Netherlands
Impact in practice
Measured performance across real-world hospital implementations.
Proven zero discharge
Broad range of medical residues, e.g. antibiotics, anesthetics, pain killers, blood pressure regulators etc.
Scaleable solution in hospital
Fit for scale: small interventions at multiple departments, collective impact.
Source capture
Cost-effective targeting specific substances and high concentrations before they are diluted downstream.
Reduce AMR
Antibiotics intercepted before entering sewers, reducing exposure and resistance risks.
