Increased use of renewable energy is crucial for promoting energy supply security, sustainable and affordable energy, technological development, and innovation. Technological and industrial leadership should, at the same, time ensure environmental, social, and health benefits.
The European Union’s climate and energy policy has been incorporated in the RED II Directive and the next RED III Directive, which both state the criteria for sustainable development and reduction of the greenhouse gas emissions for biofuels, bioliquids and biomass fuels.
Sustainable development criteria (KZR) mean requirements stated in article 29 paragraphs 2-7 of the RED II Directive, which have to be fulfilled for fuels from forest and agricultural biomass, residues and waste from agriculture, forestry, aquaculture and fishing, so they can be listed as sourced in a sustainable way for natural environment.
KZR INiG is a certification system created in Poland by Oil and Gas Institute. It is recognized worldwide and is the only system that allows for simultaneous certification of biomass for fuel and energy purposes, including biogas. The requirements of KZR INiG system are in accordance with the requirements of not only RED II Directive, but also RED III, and include national conditions. Implementation of the KZR INiG system, for companies in the biofuel, bioliquid or biocomponent supply chain, is a proof that their company fulfills the requirements of sustainable development.






The KZR INiG System includes every entity that physically manufactures biofuels or biomass, or the ones that sell them, including:
✓ Agricultural and/or forestry producers
✓ Biomass processors
✓ Heat and/or energy producers
✓ Residue/waste generation zones
✓ Waste and residue collectors
✓ Suppliers of solid biomass fuels to power plants and heating plants
✓ Suppliers of motor fuels to the market
✓ All other entities in the biofuel, bioliquid, and biomass fuel supply chain
It means that the users of the KZR INiG System are all operators in the supply chain, beginning with the place of origin, through the sellers and recipients, all until the heat/energy suppliers. Each operator is individually certified and, if possesses said certificate, can sell their biomass with an attestation proving that it fulfills the sustainable development criteria (KZR). The requirement for this is, however, the acquisition of sustainable development criteria certified biomass. Each operator has a different set of requirements depending on their place in supply chain.
KZR INiG certification can cover products used to produce biomass, biofuels, and biocomponents. These include: cereal grains (e.g., rye, corn), oilseeds, processed biomass (e.g., vegetable oil), biofuels, biocomponents, along with waste and residues.
Meeting the sustainable development criteria can certainly expand your company’s scope of operations, increase the number of contractors, influence higher profits related to the prices of certified products, and ultimately change the current position of your business on the market.
Certification guarantees verification of the correctness of the internal processes - an auditor from an independent certification body confirms that the procedures used in the company allow for identification of a given batch of sustainable biomass in terms of its use in the production of heat and electricity. This verification is carried out individually for each business, and each receives its own certificate. A certified entity is able to sell biomass with a POS (Proof of Sustainability), while purchase–sale documents are verified during the audit. Guidelines for entrepreneurs regarding verification (mass balance rules, greenhouse gas emission calculation, flow management, product sales, audit sampling, control question lists) are defined in the system documents. All auditors verify enterprises according to the same list of control questions.
The KZR INiG System, as part of its oversight of the System’s activities, conducts inspections of certification bodies and enterprises.
