Liming Materials from Industrial Processes

The repurposing of factory waste is an excellent environmental management strategy and offers many benefits to farmers and factories, particularly economic benefits. However, quality control in this field is vital. For that reason, the BNQ has developed standard BNQ 0419-090, which specifies the characteristics of calsic and magnesic conditioners deriving from industrial processes, as well as the criteria and test methods used to evaluate their characteristics. The standard applies to industrial products and by-products used to ameliorate soil and derived from, for example, the dust collecting system of lime kilns, pulp and paper mills, metal recovery, Portland cement manufacturing and egg shells.

 

Certification Offer

Marque de certification - Amendements calciques ou magnésiensBuyers of mineral conditioners are concerned to purchase quality products and they systematically trust the products recognized by the BNQ as conforming to BNQ standard 0419-090. The certification of mineral soil ameliorants is based on four documents, including the BNQ 0419-910 certification protocol. This document describes the certification requirements and procedural rules applicable to the certification of calsic or magnesic ameliorants or mixtures of calcic or magnesic ameliorants deriving from industrial processes, in accordance with the requirements of BNQ 0419-090. The program’s requirements are divided into four categories:

  • Specific requirements;
  • Sampling;
  • Marking;
  • Company quality management system requirements.

This certification program is accredited by the Standards Council of Canada.
