Opis:: The effects of different volumetric ratios of bulking agents to pulp/paper-mill sludge on composting were studied. Rice husk and corncob were used as bulking agents. Volumetric ratios of bulking agents to pulp/paper-mill sludge were used as 10:100 and 25:100. To monitor the evolution of the composting systems, routine parameters such as temperature, moisture, pH, total N, NH₄ +-N, NO₃-N, total C, and C/N ratio were analyzed. The results indicated that the agro-based materials significantly affected compost maturity parameters. Moreover, the quality of the product obtained in the composting process treated with the agro-based materials achieved satisfactory stabilization and sanitation for application to land.

Opis:: The aim of this work is to compare the environmental impacts of two production processes of tissue paper using virgin pulp (virgin fiber) or waste paper pulp (recycled fiber). This comparison is based on the materials and energy used as well as emissions and waste resulting from the production of tissue paper. Life cycle assessment (LCA), ReCiPe method, was chosen as the analysis tool. The results of the research proved that electricity has the most considerable participation in the overall environmental impacts in both production processes, followed by either virgin pulp or heat. Consequently, these two production processes are the greatest contributors to the following midpoint environmental impact categories: human toxicity, climate change, human health and ecosystems, and fossil depletion. The analysis based on endpoint impact categories proved that the production process based on waste paper is more environmentally friendly than the one based on virgin pulp in all impact categories: human health, ecosystems, resources. This is largely because of its lower material and energy requirements in the entire life cycle. Due to the fact that the tissue paper is the final use of fiber, using recycled waste paper is strongly recommended. The obtained research results are a valuable source of management information for the decision makers at both company and national levels required to improve the environmental performance of tissue paper production.
