How do we qualify a supplier — 4 steps

01.
Initial verification (documents + offer)
02.
Testing + qualification for cooperation
03.
Process audit (remote or on-site)
04.
Delivery trial (test batches)l dostawy (partie testowe)

We review the basic product information, available volumes, origin, complete documentation, and formal compliance. We confirm the parameters through external testing, and only then do we proceed with the Delivery Trial. We assess production, storage, loading, quality control, and traceability in order to eliminate risks before entering into regular supply.

We carry out 1–3 trial deliveries and verify operational aspects such as cargo protection, timelines, completeness of documentation, and batch compliance with the end customer’s requirements.

Compliance and traceability

Depending on the product and the target market, we require or prefer the following:

Biomass (often required / preferred):

  • ENplus® A1 / A2 — if you supply certified pellet (certificate number + scope).
  • KZR INiG — if the supply enters chains that require proof of sustainable origin.
  • RED III — documentation and compliance for supply chains covered by sustainability requirements, including required declarations/data for each batch.
  • EUDR-ready — readiness to provide the data required by the customer (traceability, origin data, complete declarations, and batch identification).

Coal:

  • documents confirming origin and batch quality
  • environmental and formal compliance in line with contract requirements

Quality Requirements

Depending on the product category (biomass vs. coal), we verify batch parameters as well as cleanliness standards and transport protection requirements.

Biomass - quality requirements
Quality parameters, batch cleanliness, and consistency of source and preparation.

Biomass requires stable quality over time - we confirm batch parameters and eliminate contaminants that may affect installation performance and emissions.

  • Quality parameters confirmed for each batch: moisture, ash, calorific value, fraction/format, contamination content.
  • Batch cleanliness: no unwanted contaminants (stones, metal, glass, plastics), dust and slagging control (depending on the product).
  • Consistency: no “mixing” of sources without prior agreement; uniform preparation and packaging methodology.
Final parameter ranges are agreed per project and recipient installation.
Coal - quality requirements
Parameter protocol, grain size control, and transport protection standards.

For coal, the key factors are the parameters confirmed by protocol and fraction (grain size) control, so the fuel can be matched to burners and combustion conditions.

  • Parameters confirmed by protocol: calorific value, ash, sulfur, moisture, grain size/fraction.
  • Fraction and grain size distribution control: screening / batch blending according to the agreed tolerance.
  • Transport protection: standards for reducing losses and dusting, as well as cargo protection during transit.
Final parameter ranges are agreed per project and recipient installation.

Batch documentation and traceability

We require full batch traceability and documentation that enables quality and origin audits. As a standard, we ask for:

Cooperation process — step by step

01.
Offer submission
02.
Verification
03.
Audit / trial / testing
04.
Long-term cooperation

We begin with the offer submission via the form and the delivery of the basic product documents. Next, we verify the submission and discuss the customers’ technical requirements, volumes, and logistics model.

The next stage is an audit (remote or on-site) and a delivery trial combined with testing to confirm parameters and consistency. After successful qualification, we move to long-term cooperation: we agree on the schedule, delivery slots, KPIs, and settlement terms.
