Background and information about projects
Sieving is an essential technology in wastewater treatment.
The ICABUS is the number one solution for the removal of toilet paper pulp from wastewater.
The ICABUS
Purgatoria introduces the ‘ICABUS’
(In Channel Brush Screen). This patented machine harvests cellulose from wastewater even more efficiently.
Pulp
Particles of toilet paper in sewage orient themselves in the direction of the water flow.
Sieving
Current sieving method only holds back toilet paper pulp if very small holes are used.
ICABUS Sieve
Due to the unique angle of the sieve, the ICABUS uses the length of the fiber to filter it out of wastewater.
Cellulose recovery system for resource repurposing
“Consider the fact that 1 roll of toilet paper per person
ends up in the sewer system every week.
We get it back again!”
ends up in the sewer system every week.
We get it back again!”
On average, the Dutch use 1 roll of toilet paper per person per week. This means that around 18 million rolls enter the sewer system every single week.
Wastewater from the sewer system is collected and cleaned in wastewater treatment plants, then discharged to surface water. The sewage sludge that remains, along with the decomposed toilet paper pulp, is often incinerated. Purgatoria believes that this can and should be done differently!
Sifting toilet paper pulp from sewage as well as harvesting an important raw material.
Paper is typically reused up to 7 times before the fiber is made into toilet paper. Purgatoria aims to give the fiber at least one more cycle as a raw material or to use it to generate green energy.
