Thanks to the encapsulation of the crusher and the covered conveyor, there was practically no dust during concrete crushing, eliminating the need for the standard high-pressure spraying.
“We’re just learning to use the machine, but we’ve already reached a capacity of more than 200 metric tons per hour and 3,000 metric tons in a 12-hour shift. Who knows where we’ll end up next week, when we start proper work with a machine that is now more familiar to us?” Mikko Mähönen muses.
Recycling instead of high landfill costs
Purkumerkki is a contracting company that was founded in Iisalmi in 2015. It focuses mainly on the demolition and recycling of schools, apartment buildings and industrial buildings. Its operating area covers everywhere from Helsinki to Rovaniemi.
The company has grown quickly every year and has now become one of the major operators in the field. Currently, the company has 15 employees.
“We are renowned in the field for precise recycling of demolition materials, safe operating procedures and an appropriate fleet. We have great partners in our recycling processes, so we can minimize the amount of residual waste,” Mikko Mähönen points out.
“Bringing any demolition material to a landfill can easily cost 10–20 euros per metric ton, so recycling is the way to go.”
During the fall, Purkumerkki is finalizing the construction of its own recycling center in Iisalmi. At this center, it will be possible to separate concrete, wood, felt, insulation wool, metals and mixed waste from demolition materials.
