Ramie (Boehmeria nivea), commonly known as China grass, is the strongest and finest plant fibre which is considered one of the valuable textile entities. Despite its unique characteristics, ramie has received reasonably less importance specially in the Indian subcontinent due to unavailability of appropriate postharvesting and processing technologies. With increase in global environmental awareness, the alternative (to cotton) cellulosic natural fibre “ramie” is gaining importance in the international textile domain. Sustainable methods and technologies which could trigger the utilization of ramie fibre are in demand worldwide. This paper will describe the developments carried out in the areas of postharvesting and spinning process of ramie. An ecofriendly degumming technology of ramie fibre has been elaborated along with suitable fibre processing route of ramie-jute blends that will bring new avenue for manufacturing jute diversified market acceptable products.

Means Of Production

The relevance of the research topic is that the world has turned its face to the environmental problem, which is the created real threat of a global environmental catastrophe. The aggravation of relations between society and the environment is facilitated by a technogenic type of economic development, of a nature-destructive nature, based on the use of natural resources and means of production without taking into account environmental restrictions. Environmental innovations as a factor in increasing the economic efficiency of production in order to improve products and services require the development of technologies, which include environmentally friendly biotechnology, waste processing technologies, low-polluting technologies, etc. There is a need for radical changes in the methods and means of environmental protection, which reduce the technogenic impact on the biosphere of the Earth, and contribute to the preservation of human health.

Conductive Properties

For the development of piezoresistive sensor fibers compounds based on thermoplastic elastomer (TPE) matrix and electrical conductive carbon black powder was used. In this paper the fabrication of piezoresistive fibers by using thermoplastic extrusion method will be demonstrated. With the thermoplastic processing route (e.g. melt spinning process) smart functional senor fibers with a diameter of 300 µm where produced. Their dynamic and static electrical conductive properties where investigated by using a cycling mechanical tensile test in combination with conductive measurement. Compounds of three different SEBS type TPEs and compounds with different content of carbon black were used to investigate the influence on the drift and shift of the electrical signal during dynamic and static strain exposure. By changing the SEBS-Block copolymer matrix and by increasing the carbon black content above 45 wt% stable electrical signal with low relaxation behavior can be achieved.

Green Hotels

The paper aims at presenting the broad literature report on green hotels. Development of the “green hotels” concept and its implementation are relatively new initiatives in hospitality sector. They can be seen as the elements of the growing general global environmental awareness. Hospitality industry is one of the most rapidly expanding sector worldwide. It is strongly associated with tourism. However, with the growing palette of services offered currently by the hotels they tend to play various socio-economical roles. In many locations hotels function as a driving force for socio-economic development, serving as employers for the local population, but also providing the forum for meetings, conferences, private/family events and ceremonies. Unfortunately, hospitality is also recognised as an industry characterised by the consumption of significant amount of resources. In particular, this concerns energy and water consumption but also waste generation. Based on literature reports the paper presents impact of dynamically growing hotel industry on the environment. The evolution in customers’ preferences towards green hotels is discussed in terms of their growing environmental awareness and the level of their satisfaction. The willingness of customers to financially support green hotel practices is discussed. The theoretical background of marketing strategies is discussed. The role of communication between various players involved in hotel operations is underlined.

The goal of this study is to investigate the morphological and mechanical characteristics of water hyacinth plant fibre polymer composites using the aquatic waste of water hyacinth plant fibre as a reinforcement material. Our main objective has been to make successive sustainable products for commercial and household use using aquatic waste plants. As a filler material, the eggshell powder is used here, which is derived naturally. The composite sample's mechanical properties are increased by this process. A novel way of extracting fibre from hyacinth is used in this study by fabricating a mechanical fibre extraction machine of our own design. The main aim of this work is to convert the biological waste of water hyacinth plants into successful commercial products. Using compression moulding techniques, fibre reinforced polymer composites are produced from water hyacinth plant extracts. ASTM standards are followed for the evaluation of manufactured samples, mechanical tests, and absorption tests. Utilizing TGA analysis, it is possible to identify the maximum withstand and degrading temperatures of composite samples. In order to determine whether FTIR can reveal chemical functional groups and percentage crystallinity, XRD is used as well. The scanning electron microscope is used to locate fibre clusters and brittle fractures in composite samples. With the help of an epoxy resin matrix, the fibres from water hyacinth can be used to make particleboard and other lightweight materials. By the end of this study, it should be able to demonstrate that water hyacinth plant fibres are suitable for use as reinforcement for an epoxy resin matrix.

: By considering the global environmental issues, various factors such as industrial ecology, eco-efficiency and chemical engineering are being combined and developed advanced material known as bio-based or natural polymer-based materials. Not only the environment but also the cost-effective factors are now propelling the inclination in the direction of greater utilisation of bio-based polymers and materials. Biobased materials are generally used to make industrial products for reliable goods and applications. Biobased materials are composed of a natural polymer, reinforced with agricultural waste, natural fibres and carbohydrates like starch, lignin and cellulose. In this chapter, we have discussed the introductory part of the bio polymers e.g. cellulose, chitin, chitosan, PLA, and soy protein. Also, the mechanical properties of composites developed by using these bio polymers and their applications specifically in the areas of biomedical and packaging sectors have been discussed.

Environmental Work

Currently, in the context of the global environmental crisis, human life is accompanied by great difficulties. Their elimination requires, first of all, the improvement of environmental knowledge, which will help to further overcome the environmental crisis. The studies show that at present the work on environmental education in the universities of Azerbaijan is not satisfactory. The tendency to reduce academic hours makes it impossible to include additional environmental subjects in the curriculum. However, this does not mean that environmental awareness should be neglected. Universities have a sufficient base for environmental work, especially in the natural sciences departments. In this regard, environmental awareness has been brought to the forefront in the training of students on specialties „Biology”, „Geography”, „Physics” and „Chemistry” of Baku State University and Azerbaijan State Pedagogical University. As a result of the experiment, the effectiveness of the proposed method of environmental education of students in the teaching of natural sciences was proved, it was found that as a result of this training, significant changes will occur in the students’ attitude to nature.
