Activate your biomass
Sustainable production of activated carbon based on locally available, renewable sources.
The challenge
Wastewater treatment plants are highly efficient for the removal of many compounds, however certain trace organics including pharmaceutical residues and PFAS are not sufficiently removed. EU regulations call for advanced treatment in order to meet new standards. Powdered activated carbon (PAC) is a powerful adsorbent capable to remove these compounds from the effluent in the socalled PACAS process. Conventional PAC types are usually produced from fossil raw materials. How to make such products more circular?
Solution and impact
In an ideal world the PAC is produced from locally available renewable sources rather than fossil materials like lignite, coal and peat. This is exactly what P4S Almere (NL) has developed: high quality PAC produced from timber and prunings.
Status
Presently P4S is finetuning the plant design and preparing for starting up the operation during 2025. Circularity is a corner stone of the design: a beneficial application for any side stream, including sand (construction materials) and excess heat (supply to neighbouring industries). Allied Waters provides support to P4S with a focus on PAC technology.
