Enea Elektrownia Połaniec and Enea Ciepło obtained all of their biological materials in a sustainable manner. The companies used biomass with an SDC (sustainable development criterion) certificate in the combustion plant. Moreover, the companies use the INiG SDC biomass origin certification system. No Group companies apply the principle of cascading use when sourcing biological materials.
The stated weights are mostly derived from direct measurements taken by truck scales, company scales, conveyor belt scales and measuring meters. In the remaining companies, estimates were used in the absence of actual data. Data available on purchase documents were also used to determine the weights. Some of the equipment used to weigh products and materials has been certified. In the case of reused or recycled components, products and secondary materials used to manufacture products and provide services by the Group, the reuse and recycling categories do not overlap with each other. Accordingly, double counting has been avoided in the presented data. As regards the weight of reused or recycled components used to manufacture products, the total weight comes from LWB and pertains to paving, shackles and struts. The weight refers to all these components and has been accounted for once without additionally counting the recycled parts of these components. As for the weight of secondary materials used to manufacture products, the entire weight comes from Enea Nowa Energia. As in the case of LWB, the total weight of these materials is provided without additionally accounting for the proportion of these materials that come from recycling. The measurement of this metric has not been validated by an external body other than the assurance provider.
