Recycling

Supplementary cementitious materials (SCMs) play an essential role in sustainable construction due to their potential to reduce carbon emissions, promote circular economy principles, and enhance the properties of concrete. However, the inherent …

Research on concrete recycling has led to the discovery of many processes for recycled concrete aggregate (RCA) treatment, each with its pros and cons on quality improvement, resource requirements, or scalability. This study aimed to propose a …

This investigation is based on a quantitative method and approach from inferential statistics. This study addresses urgent need for social equality and the desire for a sustainable business environment following emerging realities, climatic …

In recommender systems, users rate items, and are subsequently served other product recommendations based on these ratings. Even though users usually rate a tiny percentage of the available items, the system tries to estimate unobserved …

Natural gas, crude oils, and their products are flammable, even explosive. Fugitive chemicals and wastes are also of concern in upstream, midstream, and downstream operations. Safety in operations is important and requires constant attention. In …

Complex petroleum mixtures are separated in refineries by volatility and solubility to make useful products. Extraction based on solubility is a primary method in manufacturing of lubricant products. The main processes involve solvent deasphating …

Coking is a process for thermally cracking large molecules in residual oils into lower-boiling molecules, leaving behind the excess carbon in the form of petroleum coke—a coal-like material. Three major coking processes are delay coking, fluid …
