New CDE sand washing plant produces high-quality building materials from 50-year-old waste in Estonia’s capital,Talinn
Estonian company Paekivitoodete Tehase (Limestone Products) have recently purchased a CDE sand washing plant to process a material that had previously been stockpiled as waste because of its high clay content. As a result, this same material is now being sold to the Estonian building materials market as high-quality, fully certified sand and aggregate.
The urban location of the new plant, which is situated in Estonia’s capital,Talinn, required the plant supplier’s proposal to contain a detailed environmental impact statement dealing with issues such as noise pollution and other site conditions likely to have an impact on residents in close proximity to the site.
CDE compiled a detailed report for the Estonian planners and, with all the information provided having received their approval, planning permission was duly granted. Paekivitoodete Tehase are Estonia’s leading producers of crushed limestone products and operate several sites in the Talinn area.The new CDE plant is installed at their Vao Quarry, which has been in operation for around half a century.The materials produced by the company are used extensively in Estonia’s burgeoning construction market.
Since they were founded Paekivitoodete Tehase have developed a reputation for innovation.‘We are seen as leaders in Estonia with regard to bringing new technologies and processes to the market,’ commented company chairman Vladimir Libman.‘The introduction of this CDE washing plant is yet another example of how we approach business.These technologies have never been used before in Estonia and we are delighted to be the first company to use them.’
The project is the first contract that CDE have won in the region through their Estonian distributors Baltem, who also represent the Northern Ireland-based company in the neighbouring countries of Latvia and Lithuania.
‘We are delighted to be working with Baltem in this region,’ said CDE’s European sales manager, Eoin Heron, who was responsible for delivering the Talinn project. ‘Through their representation of Komatsu in Estonia, they have established a reputation as a company that delivers…and we are very pleased to be working with them, not only on this project, but also a number of other significant projects in the region.’ The new CDE washing plant has been acquired specifically to deal with material that has been stockpiled as waste since Vao Quarry began production some 50 years ago.The material is a by-product of the site’s crushing processes and, until now, Paekivitoodete Tehase had been unable to find a system capable of processing it to produce commercially viable products in a costeffective manner.
However, rather than giving up on their search and simply dumping the waste material, the company continued to seek a solution and their persistence eventually paid off when they made contact with CDE at the UK’s biennial Hillhead quarry show in June 2007.
‘The problem that Paekivitoodete Tehase had was that the material they were stockpiling was very dirty with a high clay content,’ explained Eoin Heron.‘We were able to show them that we have a considerable amount of experience in working with difficult materials, such as the one they were having a problem with.’
After several site visits in the UK and Ireland, where similar problems had been encountered, and following much deliberation between the customer and CDE’s technical design team, a deal was eventually concluded for a 150 tonnes/h CDE washing plant capable of handling –40mm material.
