Following the devastating tsunami that hit Japan last year creating some 25 million tonnes of debris, 7 million tonnes being processed by four M&J Eta PreShred 6000 machines from Finnish shredding systems manufacturer, Metso.
The company said that it supplied the machines to Japan’s Kouki Corporation in April this year for integration into the Ishinomaki incineration plant, which is located on a pier and was established to clean up the area after the 30 metre high waves devastated the region.
As part of the cleanup operation the coastline has been divided into sections, with Ishinomaki being the largest. Construction company, Kouki Corporation is implementing the project on behalf the government.
According to Metso the waste being treated at the facility contains all sorts of debris from the sea, mixed up with structural components of houses and a lot of mud. However, the company explained that due to the huge amount of mud, the density of the waste being treated at the site is significantly higher than usual.
For comparison - Metso said that an average waste to energy plant in the UK handles around 650,000 tonnes per year with three M&J EtaPreShred 4000 units running in two shifts.
In addition to the four shredding units, the plant setup includes six feeding systems to supply them as well as one excavator to even out the waste, conveyed by the feeder belt and sorting lines, on the cutting table in the hopper.
Around 7 million tonnes of waste will be processed by four M&J Eta PreShred 6000 machines, operated by around 300 employees per shift, with 40 workers needed for the picking line alone.
