In 2004, the Company Conkret, as a leading manufacturer of insulation products, implemented the Integrated Management System according to ISO 9001 series and has continuously maintained it. Since 2011, we have also been certified in the area of the Plant Production Inspection, confirming that we meet the requirements of harmonised standards applying to our products. Every year we conduct a number of internal audits, to improve the quality of our work and supplied products. Our robust development, driven by extensive investments and the associated increase in production, contributed to the success of our company in the Polish and foreign markets.

From the very beginning of its operations, the company Conkret manufactures finished products using its own regranulate. We are the largest manufacturer of polyethylene regranulates manufactured from household-generated waste in Poland. 

Today, Conkret manufactures 2200 tonnes of plastic film and 2500 tonnes of regranulate a month. 50% of our sales is exported – our products are supplied to 19 countries all over the world, including Germany, Denmark, The Netherlands, The United Kingdom, and France. Conkret belongs to the largest employers in the region, employing over 250 people.

We manufacture over 30 thousand tonnes of regranulate a year. Conkret has high class equipment for recycling polyoelfin plastic materials.
