conclusions considering the weight percentage of food wastes (70%), solid wastes of babolsar city could be used for composting. also as large quantities of infectious wastes were produced by hospitals of babolsar, it is recommended that sterilization systems (hydroclave) be used for decontamination of these hazardous wastes. materials and methods this study was a descriptive and cross-sectional...

Proper chemical imaging tools are critical to the pharmaceutical industry due to growing regulatory demand for intermediate and end-product content uniformity testing. Herein we demonstrate stimulated Raman scattering (SRS) imaging of active pharmaceutical ingredient (API) and four excipients within tablets. Tablets from six manufactures were imaged with a speed of 53 s per frame of 512 × 512 p...

The reuse of mineral wastes is one of the most suitable solid wastes solutions. Throughout the world, the large of the granular aggregates used in constructions exploit natural mountain resources and rivers. Using mineral waste as a part of concrete, it can be helped to create a green environment and also contribute to sustainable development. Since the copper production process in the Sarchesh...

Land application systems, also referred to as beneficial reuse systems, are engineered systems that have defined and permitted application areas based on site and waste characteristics to determine the land area size requirement. These terrestrial systems have orders of magnitude greater microbial capability and residence time to achieve decomposition and assimilation compared with aquatic syst...

The aim of this study was evaluate the potential use of low-cost and environment friendly solvents to extract polyphenols from apple wastes for biotechnological application. Apples solid wastes from industrial transformation were used as raw material to produce extracts enriched in antioxidant polyphenols, using a green and environmental friendly solvent in a solid-liquid extraction. The reacti...

FDA's PAT Initiative provides an unprecedented opportunity for chemical engineers to play significant roles in the pharmaceutical industry. On-line process control, as an enabling process understanding tool and advanced quality control strategy, has been widely adopted in other industrial sectors. In the present manuscript, the authors will provide their perspectives on the need of chemical eng...
