| Abstract | Given the global economic issues and environmental pollution, there is a growing interest in research addressing the use of biomasses resulting from agricultural production. One main category of biomass components is lignin, the use of plant waste in the pulp industry being one of the ways in avoiding additional deforestation by suppling inputs for the paper industry. The implementation of a strategy for capitalizing the potential of renewable sources, as, but not limited to, paper production, provides the appropriate framework for decision on renewable alternatives and inclusion in the acquis domains in Romania. The present study analyzed the potential use of waste obtained from field crops, mainly annual, as wheat, sunflower, maize, soy, rape, rye, barley, sorghum, rice, to produce paper. Biomass/waste from field crops is a promising source for paper, primarily because it is renewable and has the potential to exploit over 7 million hectares of arable land, with annual use. The diversity of pedoclimatic conditions in Romania makes possible the cultivation of a wider range of species and, within them, a multitude of varieties and hybrids, with variable amounts of lignocellulosic agricultural waste. In addition, accidental years as 2022, the year with the worst drought in Europe in the last 500 years, reshaped the need of valorizing any available biomass, regardless of the production of the main crop. Our calculations show that for a paper containing 28% of renewable cellulose, with the wheat straws collected from Romania in 2019, 9633.31 thousand tons of paper would have been obtained, with an average per hectare of 2786.62 kg of paper. Our analysis shows the opportunity of using lignocellulosic agricultural waste for use as a raw material for paper production. A throughout analysis is needed in the context of extreme droughts experienced recently, to show which valorization of by-products is the most economically justified. |
