From 2008 to 2020, Chinese automobile production and sales have ranked first in the world. The huge production, sales, ownership of automobiles will inevitably lead a rapid increase end-of-life vehicles future corresponding issue resource recycling. Based on analysis practical dismantling study statistics declared by supplier 19.5% components parts with weight greater than 0.5 kg from two typic...

Abstract Background of this research is suspension packaging: fragile goods are attached to a panel cardboard by wrapping it in stretch film. The then appropriately folded, and the whole thing placed box corresponding dimensions. primary objective study identify paper types that might be used future as more sustainable alternative for wrap experimental methods utilized basically variants mechan...

A mild, efficient, and environmentally benign protocol for the synthesis of tetrahydrobenzo[b]pyran derivatives in the presence of readily accessible, biodegradable, and choline hydroxide based ionic liquid as catalyst has been established. The key features of the reported methodology include good to excellent yields of desired products, simple work-up procedure and good recyclability of cataly...

Green computing is an effective study in which disposing, recycling and manufacturing of computers and electronic devices is taken into consideration. The goal of green computing is to lower down the use of hazardous materials, maximize energy efficiency and popularize biodegradability or recyclability of out-dated products and factory waste. In this paper we discuss the wastage of energy by co...

The awareness for more environmentally sustainable packaging solutions is steadily growing. With both consumers and manufacturers looking to minimize their impacts on the environment, need easy-to-implement standardized measures strengthening a circular economy rises. In research, goal was determine whether carbon footprint circularity of non-food plastic can be improved by simple design change...

in this work, a green, simple and highly efficient procedure for the synthesis of bis(indolyl)methanes is described. the condensation of indoles with carbonyl compounds catalyzed by citric acid in water affords bis(indolyl)methanes in high yields and relatively short reaction times. the advantages of this method are using of water as a low cost solvent and efficient recyclability of the catalyst.

BACKGROUND The elements that contribute to a healthy building are multifactorial and can be discussed from different perspectives. OBJECTIVES WE PRESENT THREE VIEWPOINTS OF DESIGNING A HEALTHY BUILDING: the importance of sustainable development, the role of occupants for ensuring indoor air quality, and ongoing developments related to indoor finishes with low chemical emissions and good funga...
