<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Among the various product categories in the paper industry， the packaging paper has a large production scale， resulting in a relatively high overall carbon emissions. Under policies such as “dual carbon” targets and “carbon emission quotas”， it faces greater pressure for carbon reduction. Considering the complex industrial chain structure of the packaging paper industry， which has both “carbon source” and “carbon sink” characteristics， traditional carbon emission assessment methods often suffer from issues such as incomparable results and low timeliness. This paper expanded the assessment framework to the environmental system based on the planetary boundaries framework theory and the process-to-planet analysis framework， tailored to the specific characteristics of the paper industry. Twelve scenarios were designed based on different quantifications and raw material compositions of packaging paper， and a multi-scale carbon emission accounting model extended to the environmental system was used for evaluation. The results showed that， during the entire lifecycle of packaging paper production， the higher the proportion of waste paper pulp in the raw materials， the higher its net carbon emissions. Simply increasing the proportion of virgin wood pulp had a limited effect on reducing net carbon emissions， while increasing the proportion of straw pulp could effectively reduce net carbon emissions. Reducing the basis weight of paper products appropriately， while ensuring their performance， could decrease resource consumption and greenhouse gas emissions. Different research boundaries could affect the results of carbon emissions assessment， and a smaller research boundary might lead to biased conclusions.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[According to ISO 14067： 2018 “Greenhouse gases—Requirements and guidelines for the quantification of the carbon footprint of products”， the carbon footprint of tobacco sheets products made by papermaking process was evaluated using Simapro software. The evaluation results showed that energy consumption in the production stage was the main source of carbon emissions， accounting for 74.1%， of which the electricity consumption contributed the most to carbon emissions， accounting for 70.6% of carbon emissions. So it could be assumed that the carbon footprint of tobacco sheets products made by papermaking process mainly came from electricity consumption. Therefore， increasing the proportion of green electricity use was an important path to reduce the carbon footprint of the product. The model constructed by using Simapro software projected that when 20% of green electricity was used in the production process， the carbon footprint of the unit product decreased by 10.5 percentage points compared with that when green electricity was not used， which had a better carbon reduction effect. The study further showed that carbon reduction strategies such as improving energy efficiency， optimizing process， and synergizing industrial chain could help to further reduce the carbon footprint of tobacco sheets products made by papermaking process.]]></description>

<link><![CDATA[http://zgzz.ijournals.cn/zgzzen/ch/reader/view_abstract.aspx?file_no=202502014&flag=1]]></link>
<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[The rapid expansion of China’s chemical mechanical pulp production capacity has filled the gap of recycled fiber resulting from the implementation of the “waste restriction order”. Water environmental capacity is a renewable natural resource that restricts the development of papermaking industry. The development of papermaking industry requires water environmental capacity to mitigate the potential environmental impacts of wastewater discharge. This paper reviewed the contribution of wastewater treatment in reducing pollutant discharge. The water environmental capacity limitations faced by the improvement of domestic pulp production capacity were mentioned to propose that reducing water consumption per unit product was a necessary way to continuously minimize the environmental impact of papermainy industry. Besides， the necessity of establishing guidelines for water recycling in the paper industry was advocated， while the feasible technologies for clean production and water recycling were summarized. In order to provide a reference for promoting the sustainable development of papermaking industry.]]></description>
