Bioethanol is one of the most promising renewable resources for the production of important monomers. To date, there have been various processes proposed for bioethanol conversion to renewable monomers. In this review, the catalytic bioethanol upgrading to various types of monomers using hierarchical zeolites as catalysts is illustrated, including the recent design and preparation of hierarchical zeolites for these catalytic processes. The characterizations of catalysts including textural properties, pore architectures, acidic properties, and active species are also exemplified. Moreover, the catalytic studies with various processes of monomer production from bioethanol including bioethanol dehydration, bioethanol to hydrocarbons, and bioethanol to butadiene are revealed in terms of catalytic activities and mechanistic studies. In addition, the future perspectives of these catalytic circumstances are proposed in both economic and sustainable development contexts.

This paper focuses on the valorisation of solid residues obtained from the thermal treatment of sewage sludge. In particular, sewage sludge samples were collected from two waste water treatment plants (WWTPs) with different sludge line basic operations. After drying, sludges were heated up to 700 °C in appropriate ovens under diluted air (gasification) and inert (pyrolysis) atmospheres. The solids obtained, as well as the dried (raw) sludges, were characterised to determine their textural properties and chemical composition, including the speciation of their inorganic fraction. All the materials under study were employed as adsorbents/catalysts in H2S removal experiments at room temperature. It was found that, depending on the particular sludge characteristics, outstanding results can be achieved both in terms of retention capacities and selectivity. Some of the solids outperform commercially available sorbents specially designed for gaseous emissions control. In these adsorbents/catalysts, H2S is selectively oxidised to elemental sulphur most likely due to the presence of inorganic, catalytically active species. The role of the carbon-enriched part on these solids is also remarked.

The use of recycled materials to replace natural and artificial materials represents an interesting and real possibility for all industrial sectors to contribute to the reduction of the amount of waste disposed of and non-renewable resources consumed. This study reports the results of the measurements of the sound absorption coefficient carried out on specimens obtained from the recycling of different materials. A sustainable development of our planet requires us to adopt materials recycling policies to ensure the economical use of resources. Two types of materials have been studied: material obtained from the recycling of plastic bottles, and a material obtained from the recycling of asphalt milled. Both materials showed interesting sound absorption performances covering different frequency ranges.

This article uses the recent concept of ‘creative economy’ to argue in favour of a dynamic and holistic approach to the promotion of the cultural heritage. This implies namely that the heritage is viewed in both its material and intangible forms and as a driver of sustainable development. After an overview of the diverse interpretations, at natioanl, regional and international levels, of the creative economy, the author illustrates how the cultural heritage can benefit from the growing importance given to unlilited, renewable resources for the development of individuals and communities, especially in the developing countries. The article contains, however, words of caution on the negative effects of the creative economy and submits that these can be overcomed by extending the sphere of the cultural heritage to all areas of developement.

Sustainable development, the design of green and economically feasible processes to produce synthetic polymers is one of the major needs and biggest challenges. Catalysis of polymerization processes is among the most important applications within the field of nanoscience. Intensive research is being conducted and considerable success has been achieved in the heterogenization of various homogeneous catalysts on nano supports for polymerization of olefins and dienes. The large surface area of various nanomaterials qualifies them quite naturally to act either as a heterogeneous promoter for catalytic reactions or as a support for the heterogenization of homogeneous catalysts. To the polymerization of olefins and dienes by using nanocatalysts are devoted significant numbers of published papers, but to elucidate the possible effect of both the type and properties of nano supports and their sizes and amounts on the activity and stereoselectivity of heterogenized catalysts and the properties of the obtained polymers are needed more detailed studies. This review attempted to collect some published research materials in the field of the nanocatalysis of olefins and dienes polymerization processes and our main aim is to assess the critical points and to indicate the future perspectives and possible strategies in this area of research. We are confident that this review will be a helpful companion and deliver key hints to those, in academia and in the industry, who decide to move their research interest in this direction

Coal is one of the non-renewable resources, and in our country at present also is the main source of energy. It is very important to improve the coal mining rate, to exploit and to use the coal reasonably. Saving coal resource is an important measure for our coal industries sustainable development. Because large amounts of coal under complex conditions caused by fully mechanized mining can not be mined, the rotation mining with large angle for unequal and fully mechanized mining face and its design and main parameters are introduced in this article based on an engineering practice. Using this mining method, the coal under complex condition can be mined as much as possible. It is helpful for us to improve coal mining rate and to economize coal resources.

Green Information Technology

Green information technology systems (Green ITS) are proposed as a strategy to reduce greenhouse gases (GHGs) emissions and other environmental impacts while supporting ecological sustainable development. The Green ITS concept combines both Green information technology (IT) and Green information system (IS) applications. The Green ITS concept has the potential to combat the carbon emission problem globally, beyond simply Green IT, because it combines management, organizational, and technology dimensions of climate change mitigation and adaptation, especially if supported by global policy. Examples include life cycle assessment software for measuring GHG emissions, and software for monitoring GHG emissions. Previous studies on environmental burdens such as GHGs, water and air pollution, energy losses and other forms of waste alongside socio-economic dependent variables including renewable resources and climate change policies are reviewed and synthesized. The research analysis conjointly points to the usage of renewable resources such as solar and wind as a critical strategy to scale back GHG emissions and enhance green growth. Empirical evidence shows that developed countries can reduce their carbon emissions while developing countries can utilize carbon emission-free technologies as they aspire to achieve development. The two significant benefits of the Green ITS strategy are first, to provide the environmental benefits of reducing greenhouse emissions and other environmental impacts and second, to enhance global green growth, which supports achievement of ecological sustainable development. Green ITS tools support achievement of the UN SDG 7, 13 and 15, which emphasize clean energy, climate action and ecological sustainable development, respectively. Future research directions include the formulation of a strategy to combat GHGs and design of a system to monitor carbon emissions and other waste remotely.
