DAM technology to reduce the presence of microplastics in AATs

Plastic waste that is not reintroduced into the production cycle is one of the main environmental and economic problems facing the European Union. Because of this reason, community agencies take the lead worldwide in making 100% of plastic packaging recyclable, reusable or compostable by 2030.thus moving towards a circular economy model. Therefore, it is very important to find new recycling processes, especially for PET trays, PET/PE and PET/PP multilayers, or the plastic packaging fraction that is not currently recycled. the microplastics.

Specifically, the presence microplastics (MP) represents a global challenge due to its widespread distribution, ubiquity and impact on terrestrial and aquatic organisms and even human health. These have become one increased concern in public administrations and management companies due to the presence ofboth in wastewater and drinking water.

In the special case of AATs, In addition, microplastics can adsorb other contaminants, are retained in the sludge line or pass through the waterline to the receiving environment. That’s it they need to be separated, identified and quantified.

The greatest difficulty for their separation lies in the fact that: microfibers are much less thick than they are long, is very difficult to detect at high flows with a lot of variability and mixing. For these reasons, research is increasing in the field of wastewater treatment aimed at developing treatment technologies for the separation and elimination of microplastics.

“This fundamental Developing new technologies that help detect and remove emerging pollutants and microplastics from wastewater, thereby ensuring and improving safety for reuse. “If we want to transform WWTPs into resource generating plants and thus apply circular economy principles, we have to solve this problem,” they say.

DAM Group’s projects on microplastics

this DAM Group He has extensive research experience in microplastics and is very actively involved in different research projects. National Environmental Congress (CONAMA) closed today progress has been made in the european project ENZICLE.

“Especially in We study the enzymatic degradation of ENZYCLE microplastics and also the effect of these additives on other processes such as anaerobic digestion or composting,” they state from DAM’s R&D Department.

DAM has been one of the first companies in the sector to provide a solution to this problem.already from your approach FIBERCLEAN project Started in 2017 and recently completed hworking how to reduce microfiber emission in the production and care of fabrics and garments. For this purpose, a system was developed that was implemented on a pilot scale and made it possible to separate more than 80% of microplastics found in water treatment processes.

“The pilot plant used, an elution system allowing the separation of microplastics according to the density difference, as well as a centrifuge module using a hydrocyclone,” states DAM researchers.
