The University of La Laguna (ULL) has taken an important step forward in research into microplastics on Tenerife. With support from the island government, a new, strictly controlled research facility has been put into operation. According to the institutions involved, the laboratory is equipped with technology that is unique in the Canary Islands. It enables scientists to detect minute plastic particles in drinking water, wastewater, compost, soil and sediment, among other materials.
Infrared Light and Laser Imaging
The Cabildo of Tenerife is investing more than €1.08 million in the research project between 2024 and 2028. One of its key components is the so-called ISO 6 cleanroom: a space in which the air and working conditions are monitored particularly carefully. This is necessary because even fibres from clothing or dust particles from the surrounding environment can contaminate a sample. Without such a protected space, there is a risk that researchers may detect plastic particles that were not originally present in the water or material being examined.
The laboratory uses LDIR technology, among other methods, combining infrared light and laser imaging to automatically identify small plastic particles. The equipment can count and measure the particles and determine what type of plastic they are made of. This makes it possible to examine complex samples, such as compost, leachate from waste-processing facilities, beach sand and water, with greater accuracy.
Microplastics
At the same time, the specialised POLAR unit has been further expanded. The name stands for Polymer Analysis and Research. This ULL department focuses not only on scientific research, but will also carry out analyses for public authorities, water companies and other organisations. They will be able, for example, to have drinking water or treated wastewater tested for the presence of microplastics.
Microplastics are plastic particles ranging in size from approximately one micrometre to five millimetres. They are produced, among other things, by the wear and breakdown of packaging, synthetic clothing, car tyres, paint and other plastic products. Because of their small size, they can spread easily through the air, water and soil. In addition, they break down only very slowly.
Identifying Sources of Pollution Earlier
For Tenerife, this research is particularly relevant. The island depends heavily on careful management of water, waste and vulnerable natural areas. Improved measuring methods can help identify sources of pollution earlier and enable targeted action to be taken. The project is also examining whether certain plastics can be used to absorb other organic pollutants from liquids. As a result, the research is looking not only at the presence of microplastics, but also at potential applications in waste and water treatment.
The new infrastructure is intended to prepare Tenerife for stricter European regulations on monitoring microplastics in drinking water and wastewater. At the same time, the project provides employment and training opportunities for young researchers. Two PhD candidates are carrying out their research as part of the programme.
For residents and visitors, little will change in everyday life for the time being. Behind the scenes, however, Tenerife is gaining a scientific tool that could become important for cleaner water, improved waste management and a more accurate understanding of plastic pollution on the island.
