Our method of recycling excavated material handles the simpler materials that make up the largest flows in society. The mobile plant is expandable from simple recycling to more advanced. The washing part of the plant is developed by Finlay and fits well with Norditek's Screening plants and wind screens.

The plants can deal with muddy and sticky masses and obtain very small fractions. It is possible to obtain fractions down to 0.1 mm. This results in very high quality stone, soil and sand.
