Wind Turbine Blades: End-of-Life Scenarios
Large expansion of wind energy is expected in next decades. At the same time, a significant proportion of the installed wind turbines, the generation installed in 2000s, will come to the end of their lifetime between 2020 and 2030. Many parts of wind turbines can be recycled, however, this is seldom the case for the composite wind blades. Wind turbine blades are developed and designed to sustain challenging service conditions and extraordinary mechanical and ennvironmental loads for several decades. Therefore, their afterlife destruction and separation into re-usable elements represents a challenge. In this review, strategies of end-of-life management of wind turbine blades are discussed. Various scenarios of end-of-life management of wind turbine blades are considered. “Reactive” strategies, designed to deal with ageing turbines, installed in 2000s, include improved maintenance and repair technologies, reuse, refurbishment and recycling.  “Pro-active strategies”, applicable to f new generations of wind turbines, include wind turbine blades with thermoplastic and recyclable thermoset composite matrices, as well as wood, bamboo and natural fiber based composites.

Solar Energy Technologies' Sustainable Development towards Solar Photovoltaics
Renewable energy was available in rural areas in the form of wind farms, solar plants, biomass plants and others. In urban contexts, particularly with the use of solar energy technologies called solar energy systems in buildings, such as solar thermal and photovoltaic (PV). The viewpoints on solar energy technologies for sustainable development is  particular to emphasis on photovoltaic (PV), as well as the solar energy technology performance, in order to ascertain worldwide solar energy adoption trends.

MSWI-BA in Cement-based Materials Review
Waste management is a vital environmental issue in the world today. Municipal solid wastes (MSWs) are discarded in huge quantities on a daily basis and need to be well controlled. Incineration is a common method for reducing the volume of these wastes, yet it produces ashes that require further assessment. Municipal solid waste incineration bottom ash (MSWI-BA) is the bulk byproduct of the incineration process and has the potential to be used in the construction sector

Low Calcium Fly Ash/Slag Geopolymer
Geopolymer materials consist primarily of an aluminosilicate source and liquid alkaline constituents. Geopolymer has a lower footprint in terms of CO2 emissions and has been considered as an alternative for ordinary portland cement (OPC), which is known for its significant contribution to carbon dioxide emissions.

Possibilities and Opportunities in the Indian Steel Industry
Demand for iron ore has been increasing with the increased production of iron and steel in developing countries such as India and China. However, the quality of iron ore has deteriorated over the years globally due to long-term mining. The low-grade iron requires beneficiation before agglomerating for use in the iron-making process. The iron ore interlocked with silica and alumina has to be liberated for efficient beneficiation.

Texturing Methods of Abrasive Grinding Wheels
Creating textures on abrasive wheels is a strategy that allows a significant improvement in grinding operations. The reduction of the internal stresses in the workpiece and the temperature during the grinding operation generates an increase in the dimensional accuracy of the workpiece and a longer tool life. Textured abrasive wheels can be produced in many different ways. Depending on the processing method, the dimensional accuracy of the tool and its applicability is changed.

Guard Rail
Guard rail, guardrails — or railings around properties and more generally outside of North America in some uses overlaps the industrial term "guide rail". They are a boundary feature and may be a means to prevent or deter access to dangerous or off-limits areas while allowing light and visibility in a greater way than a fence. Common shapes are flat, rounded edge, and tubular in horizontal railings, whereas tetraform spear-headed or ball-finialled are most common in vertical railings around homes. Park and garden railings commonly in metalworking feature swirls, leaves, plate metal areas and/or motifs particularly on and beside gates. High security railings (particularly if in flat metal then a type of palisade) may instead feature jagged points and most metals are well-suited to anti-climb paint. A handrail is less restrictive on its own than a guard rail and provides support.

Image-Based Crack Detection Methods
After preprocessing of images, a multiple directional non-minimum suppression (MDNMS) method is applied for crack detection. A linear SVM classifier is used to differentiate between various pavements across Spain to determine optimal parameters for crack detection. The performance of the crack detection method is improved by adapting parameters specific to the pavement.
