With the increasing decline in the environment and natural resources it is important to find new ways in which manufacturing can increase the sustainability of the world. This study seeks to compare LimeX, a state-of-the-art paper and plastic alternative primarily made of limestone, with conventional paper and plastic materials. For a better understanding of LimeX as a material, a brief investigation of the mechanical and chemical properties will be performed through experimentation and analysis. In addition, this paper aims to evaluate the sustainability of LimeX through the analysis of metrics relating to the triple bottom line (environmental impacts, economic impacts and societal impacts) to evaluate and compare the sustainability performance of LimeX products with conventional paper and plastic products. The previously developed Product Sustainability Index (ProdSI) will be adapted and used in this study to conduct the sustainability evaluation. Major findings will include results from an experimental analysis of LimeX via SEM and EDS, and LimeX material property measurements via tensile testing and density measurements. In addition, there will also be a comparison of the sustainability performance of conventional paper and LimeX using a simplified ProdSI. The study found that LimeX was marginally more sustainable than paper, but this evaluation could change with information from the development of a life-cycle analysis report on the material.

The 2021 United Nations Food Systems Summit (UNFSS) was a call from the UN that brought together key players with the objective to provide potential solutions for transforming current food systems and increasing their sustainability, resilience, equitability, nutritional value, and efficiency. Key actors from science, business, policy, healthcare, the private sector, civil society, farmers, Indigenous Peoples, youth organisations, consumer groups, environmental activists, and other key stakeholders came together before, during and after the Summit, to review how food is produced, processed, and consumed across the world in order to bring about tangible, positive changes to the world’s food systems.The White/Wiphala Paper on Indigenous Peoples’ Food Systems (FAO, 2021a) was a critical reference, an evidence-based contribution to the 2021 UNFSS that highlights the crucial role of Indigenous Peoples and their food systems as game-changers and shows us how we can respect, better understand, and protect said systems. The paper resulted from the collective work of Indigenous Peoples’ leaders, scientists, researchers, and UN staff. More than 60 Indigenous and non-Indigenous contributions from 39 organisations and ten experts in six socio-cultural regions were received by the Global-Hub on Indigenous Peoples’ Food Systems. The Global-Hub on Indigenous Peoples’ Food Systems is a knowledge platform that brings together Indigenous and non-Indigenous experts, scientists, and researchers to co-create intercultural knowledge and provide evidence about the sustainability and resilience of Indigenous Peoples’ food systems (https://www.fao.org/indigenous-peoples/global-hub/en/), which coordinated the writing and editing of the paper through a Technical Editorial Committee.The White/Wiphala paper emphasised the centrality of a rights-based approach, ensuring Indigenous Peoples’ rights and access to land, natural resources, traditional territorial management practices, governance, and livelihoods, as well as addressing the resilience and sustainability of their foods systems. The paper demonstrates how the preservation of Indigenous Peoples’ food systems is necessary for the health of more than 476 million Indigenous Peoples globally while providing valid solutions for addressing some of the challenges humankind faces on sustainability, resilience, and spirituality.It is essential to note critical developments that have occurred since the White/Wiphala paper was published in mid-2021, the July Pre-Summit in Rome, and the September Summit in New York, followed by COP26 in Glasgow in November 2021.For example, at COP26, little attention was given to food systems, despite their contribution to the climate crisis, with responsibility for 30% of greenhouse gas emissions (FAO, 2021b). COP26 highlighted the need to focus on mitigation strategies and adaptation in the face of the current climate crisis. These strategies must include Indigenous Peoples’ food systems as game-changers for effective climate adaptation strategies that they have been testing and adjusting for hundreds of years.At the UNFSS Pre-Summit in Rome, the Indigenous Peoples’ delegation voiced their concerns and presented three key proposals: the recognition of Indigenous Peoples’ food systems as a game-changing solution; the launching of a coalition on Universal Food Access and Indigenous Peoples’ food systems; and the request to create an Indigenous Peoples’ fund. All their concerns and proposals were rejected at the Pre-Summit, including launching a Coalition on Indigenous Peoples’ Food Systems and Universal Food Access.In the aftermath of the UNFSS Pre-Summit, and thanks to the leadership of the Chair of the UN Permanent Forum on Indigenous Issues (UNPFII), Indigenous leaders following the UNFSS, seven countries, and the FAO Indigenous Peoples Unit (PSUI), timely discussions and collective work led to the creation of a new Coalition on Indigenous Peoples’ Food Systems.Thanks to the leadership of Mexico and the support of Canada, the Dominican Republic, Finland, New Zealand, Norway, and Spain, along with the support of the UN Permanent Forum on Indigenous Issues (UNPFII), the Global-Hub on Indigenous Peoples’ Food Systems, and FAO, this Coalition was announced at the New York September UNFSS Summit.The Coalition on Indigenous Peoples’ Food Systems builds upon the White/Wiphala Paper, establishing the objective of ensuring the understanding, respect, recognition, inclusion, and protection of Indigenous Peoples’ food systems while providing evidence about their game-changing and systemic nature. To support this objective, the Coalition organises its work around two main goals: Goal 1: Respect, recognise, protect and strengthen Indigenous Peoples’ food systems across the world; and Goal 2: Disseminate and scale-up traditional knowledge and good practices from Indigenous Peoples’ food systems with potential to transform global food systems across the board.

To develop engineered systems with enhanced functionality, improving their design is essential. Robots and humans each have specialized competence advantageous to design. Robots excel in terms of fabrication reliability and observation of trends in data whereas humans have prior knowledge and experience to inform decision making. By enabling robots and humans to collaborate on design problems, we may be able to achieve the best of both worlds. We explore this concept for the design problem of paper airplanes with an objective to reach a target distance and present various collaboration mechanisms for iterative design, test, and evaluation processes. We demonstrate that with the optimal collaboration technique where the robot provides initial design exploration followed by human exploitation, a target-reaching design is found quicker than other collaborative or non-collaborative methods. This work presents an initial exploration of collaborative human-robot design methods which could inform future methodologies for increasingly complex design problems.

Analysis of roll products at the final stage of production is the main stage for identifying defects, disrupted integrity or homogeneity, etc. Paper production is a typical example of such an operation in an industrial setting. It is proposed to use the results of the assessment for opacity, described by several standardized and statistical estimates, as the main characteristic for the quality of paper products. Studies of the dependence of the quality of the paper web on the production conditions and the properties of raw materials produce considerable variance, so that it is impossible to make accurate predictions. For this reason, we used a neural network modeling technology to develop an intelligent system for monitoring the quality of the paper web. Online quality control allows to assess the efficiency of the paper machine and rapidly adjust the manufacturing execution system. Special technologies such as computer vision systems can be introduced for this purpose, making it possible to make a transition from subjective assessment of the structure and defects of the paper web to obtaining objective quantitative estimates of these indicators. We considered a procedure for determining the estimates of structural heterogeneity of the paper web at the final stage of its production. We suggest to expand the classification of finished product samples by using neural fuzzy interpolation of linguistic values of such indicators. The approach introduced is aimed at improving the efficiency of the production process.

Paper has many uses such as in writing, printing, packaging, paper money, cheques voucher, cleaning, as construction materials, etc. Based on its applications, paper may be characterized as bank paper, book paper, bond paper, construction paper, cotton paper, electronic paper, photo paper, wallpaper, etc. The popular raw materials used to make paper are esparto-grass, straw, wood, flax, hemp, jute and rags-cotton and linen. The paper manufacturing process consists of two main stages: pulp making and conversion of pulp into paper. The process of producing pulp may be done by chemical or mechanical means, or by a combination of both depending on the nature of raw material used and the end application of the produced paper. Three operations are required to manufacture paper that are beating, conversion of pulp to paper and finishing. This chapter comprehensively covers the types of papers, their uses, raw materials and their manufacturing processes. Pulp and paper mills have adverse effects on the environment such as depletion of forest covers, and chemical pollution caused by liquid effluent discharges, solid wastes and air emissions from particulates, H2S, NOx, SOx. These have been covered in detail including means to reduce their emissions and treatment methods.

As one of the precious intangible cultural heritages, traditional Chinese paper cutting has a long history and profound cultural connotation. In the digital age, traditional paper cutting is gradually moving towards digital paper cutting in order for better inherit and development. In the research of paper cutting digitalization, computer has been normally adopted to make two-dimensional paper cutting, to focus on the restoration of paper cutting process. There is still a little difficult for users who are not familiar with paper cutting; three-dimensional model has also been used to improve the picture effect, but it is not easy to show the characteristics of paper cutting with three-dimensional models. In order to address such an issue, this paper innovates the artistic style of digital paper cutting by combining paper cutting with common visual effects in modern 2D games, improves the efficiency of scene construction by writing automatic generation algorithms, and perfects the interactive mode of digital paper cutting by introducing natural interaction. In this way, users can participate in the process of creating paper cutting works, and creation of paper cutting works becomes simple and efficient benefiting from the automatic generation algorithm and natural interaction. Finally, by comparing to works of other paper cutting style, the works achieved by the solution proposed in this paper illustrates the advantages of digitalization in three aspects: artistic style, fast generation, and natural interaction.
