Innovation Strategy supported Pennotec in developing a process to reduce contamination and potential pollution from slurry run-off. 

 

River pollution is a topical issue in Wales with only 44.5% of waterways considered as in good ecological status. Slurry run-off is one of many contributing factors to poor water quality and reducing its impact on rivers will help to improve Wales’ water quality. 

 

Pennotec have developed a process to separate slurry into it’s solid and liquid components using a material derived from seafood shells. The process reduces the volume of slurry to be stored making storage until application onto the land more manageable for farmers. Pennotec have also developed a way of using seafood shells to absorb nitrates and phosphates from the liquid portion of the slurry leaving relatively clean water which is safe to re-enter the natural watercourse.
