Our story stretches back to the beginning of the 1950s,  when within the framework  of Mining and Metallurgical  Works Boleslaw in Bukowno , the zinc oxide metallurgical plant  was established. It had 13 kiln units and 2 sintering kilns,  40 m long and 3m in diameter. They were used for the fire processing and enhancing  of zinc ores called zinc spars.

In the early 1970s,   Poland was the leader in Europe in the processing of oxides from  zinciferrous charge with production estimated at 1600 000 mg per year. The kilns installed in Bukowno constituted 35% of  the objects of this kind operating in Poland at the time.  
Boom in Polish processing industry had continued till the early 1980s, when the exploitable zinc spar sources ran out. The situation resulted in closing down a number of plants relying on them. 
Boleslaw Metallurgical Works was the only plant in Poland which survived that difficult period in the industry thanks to changing the type of charge and decreasing the number of rolldown furnances from 4 to 2.   
Sludge coming from hydrometallurgy works  as well as imported zinc dust from an electric steel melting shop became the basic charge for rolldown furnances in Boleslaw.  The change of charge, implementation of stricter  rules and regulations with regard to the protection of the environment  and new labour law made the plant adapt to the new circumstances, posing several previously unknown technical, technological, ecological and even management difficulties.

The debate about the future of the zinc oxide division started in the early 1990s and resulted in establishing Boleslaw Recycling on the 28th April 1998. Based on a part of Boleslaw Metallurgical Works, Boleslaw Recycling has undergone continuous modernization process and its effects are:

  • ability to process zinciferrous waste at the amount of 180 000 mg per year
  • manufacturing of 50 000 mg of Zn and Pb per year 
  • improvement of the end product’s quality
  • multiple decrease in dust emissions and fugitive emissions into the atmosphere
  • elimination of sulphur compounds emissions into the atmosphere thanks to creating the centre of the installation for desulphuration of gases
  • meeting the BAT standards 
  • wider assortment of concentrates 
  • higher competitiveness on the European Markets
  • installation for desulphurisation of gases
  • first in the EU installation of this type working with Waelz furnances
