This manuscript investigates the waste paper management (WPM) of an educational Institute and aware the people about the importance of waste paper management and recycling of waste papers by multidimensional approach. The research assessed two multi long term plans, considering all recycling settings feasible for educational scenario. To complete that purpose, support for the collection of waste papers, final disposal and environmental and financial impact assessment concerning transportation is required. Results suggest that the quality of handmade papers is improved by doping some external materials in cellulose of waste papers. In this manuscript, flour of wheat is mixed in waste paper cellulose. The analysis of handmade paper is done by a photometric test. It is found that at some percentages of doping of flour in waste paper pulp, the reflection properties of the paper is increased and surface of paper become smooth and hard. At some other percentages of doping, the papers are shown absorption properties.

Floriculture has been associated with culture and heritage since very ancient time in our country. According to Tata Energy Research Institute (TERI), the waste generation rate in India is increasing at the rate of 1.0 -1.33 per cent annually.  In most of the developing countries like India, the floral waste generation occurs largely during worships, festivals, ceremonies etc. from temples, mosque, flower market, flower exhibition and wedding halls find their way into the garbage as a waste causing various environmental problems. This paper discusses the use of solid state fermentation to convert floral wastes into a variety of value-added products like as compost, biogas, bioethanol, dyes, food products, biosurfactants production, incense sticks and handmade paper production etc. and floral waste can thus be converted into wealth.

AbstractKorean hand papermaking is a renowned cultural tradition in the Korean peninsula. It is still practiced while scientific analysis of paper itself from a large data set is rare. In this study, a set of more than three hundred Korean handmade papers, collected in a reference collection book Hanji: Korean handmade paper, were chemically investigated, and their property data such as colour, pH, grammage, thickness, tensile strength, folding endurance were statistically analysed in order to determine general features for Korean papers. The influence of different paper sheet formation methods (Heullimtteugi vs Gadumtteugi) were revealed by multivariate data analysis and the chemical profiles of raw materials were studied by pyrolysis–gas chromatography/mass spectrometry (Py-GC/MS). The Korean handmade paper samples display colour gamut in the colour space L* (69.9–95.9), a* [(−3)-3], b* (0–20), most have neutral/alkaline pH values. Paper density, fiber orientation and physical properties are influenced by the sheet formation techniques. For instance, Gadumtteugi tends to produce papers with strong fiber orientation while Heullimtteugi produces papers with more evenly distribution of fibers. In addition, Py-GC/MS analysis results show that paper mulberry fibers contain less intensity lignin monomers and more terpenic compounds in comparison with gampi and mitsumata fibers. This study provides paper analysis from large sample set, statistics reveal that the material preparing and making craft determined the paper structure which reflected in their physical properties. These properties influenced paper performance and applications in art creations as well as relics conservation and restoration. The characterized paper sample database could be used for handmade paper studies in East Asian region. Consequently, this study contributes to a better understanding of contemporary Hanji properties as well as improves knowledge on handmade papers from the Korean peninsula.

There have been recent attempts to revive the traditional production of handmade paper from the bark of the Coi (Streblus asper Lour.) tree in Thailand. A sheet sample of Coi handmade paper, made from the traditional production, was collected and examined microscopically for the first time. Film-like material and cubic calcium particles were found on the sheet sample surface, which is consistent with the results of the authors’ previous research. Meanwhile, handsheets derived from Coi pulp fiber, freshly made in the laboratory, demonstrated a low air permeance and brightness with high opacity due to the film-like material and cubic calcium particles. With a high felting power of Coi pulp fiber coupled with a possible strengthening role of the film-like material, both the beaten and unbeaten fibers were used to form handsheets with high strength. Some potential aspects of Coi pulp fiber suitable for creating a unique Thai banknote paper have been demonstrated, for which further studies are suggested.

En el presente artículo se presentan los resultados del proyecto que tuvo como objetivo elaborar un nuevo tipo de papel artesanal a base de residuos agroindustriales, para comparar algunas de sus propiedades con el papel industrial. Los desechos agroindustriales se componen principalmente de tallos, raíces, hojas u otras partes de plantas como el bambú, el carrizo, el plátano, el agave, la piña, y el coco. Dichos residuos son apartados y clasificados como materiales “inútiles” y constituyen una fuente importante de contaminación. Resulta importante indicar que en los últimos años, ha existido una  relación  directa  entre  la  acumulación excesiva  de  estos  desechos  con  el  incremento de  la población humana, ya que se han tenido que destinar grandes cantidades de extensiones de tierra para el cultivo de frutas y vegetales para atender la demanda de alimentos de las personas. El desarrollo de este proyecto constó de 4 etapas, las cuales se obtuvieron al combinar la Metodología de Ecodiseño de la Sociedad Pública de Gestión Ambiental del Gobierno Vasco, IHOBE; y la Metodología de Desarrollo de Productos de Ulrich y Epigger, a las cuales se agregó una fase experimental. La Etapa 1 constó de toda la investigación de campo y bibliográfica que fue realizada para sustentar el proyecto, también se obtuvo el inventario del Ciclo de Vida del papel industrial. Posteriormente, en la Etapa 2 se utilizó el Método de Diseño de Experimentos para efectuar un conjunto de pruebas con distintas formulaciones de los componentes del papel artesanal, variando las proporciones de fibra y aditivo. En la Etapa 3 se definió el inventario del Ciclo de Vida del papel artesanal, además se determinó el diagrama de procesos de operación para su fabricación. Finalmente, en la Etapa 4 se realizaron un conjunto de pruebas físicas, además se compararon los inventarios del Ciclo de Vida y las características del nuevo papel artesanal y del papel industrial.
