This document is an update of the original White Paper published in 2024. The update incorporates evaluation of the recyclability test results in line with the 2025 4evergreen Evaluation protocol. By updating the analysis in line with the new protocol, we ensure that the results reflect the latest scientific developments in recyclability testing and evaluation.<\/span><\/strong><\/p>\n<\/div>\n

Paper sacks are made from renewable raw materials. The virgin fibres in paper sacks are sourced from sustainably managed forests, using as a starting point the capacity of forests to bind CO<\/span>_{2<\/sub>. Paper sacks store carbon and the recycling of paper and board products delays this CO<\/span>_{2<\/sub>\u00a0<\/span>from returning to the atmosphere. Subsequently, the recycling of paper sacks at end-of-life should be encouraged and pursued.<\/span><\/p>\n}}
CEPI Eurokraft and Eurosac commissioned independent research that demonstrates that not only are unused and used paper sacks perfectly recyclable but that they also offer product and process benefits when incorporated into the recovered paper fibre furnish. The results of this systematic and independent analysis challenges long-standing and engrained perceptions that sack kraft paper and paper sacks present problems for recycling.<\/p>\n
The results were published in Paper Technology International \u201cInvestigating the papermaking potential from recycling kraft paper sacks with standard high-volume paper mills\u201d and revealed that the majority of paper sacks placed on the market in Europe are recyclable also in standard high-volume paper mills as assessed using Cepi recyclability test methodology. This important study also identified that the inclusion of fresh long sack kraft fibres enhanced the strength of recycled paper. Increasing sack kraft fibre content also improved pulp drainage which offers potential to save mill energy. The work provides, for the first time, unequivocal evidence that kraft paper sacks can be recycled in standard mills and that the long fibres increase paper sheet mechanical properties and improve pulp drainage rates.\u00a0<\/span><\/p>\n
