A simple and flexible flowsheet process for recycling efficiently and selectively metals from spent fluid cracking catalysts
(Corresponding) Soares H., (Corresponding) Sadeghi M., (Corresponding) Jesus J., (Corresponding) Pinto E., (Corresponding) Almeida A.
Topic:
Solid waste management
Fluid cracking catalysts (FCCs) are used in the oil industry to crack large molecules into smaller hydrocarbons of interest, such as gasoline and other products. Considering the large volume of FCCs waste generated on a yearly basis (about 20 thousand tons of spent FCCs worldwide) as well as its...Read more

Hyperspectral imaging based cascade detection applied to paper, cardboard, plastics and multilayer packaging sorting
(Corresponding) Bonifazi G., Gasbarrone R., Serranti S.
Topic:
Solid waste management
Recycling of post-consumer packaging wastes involves a complex chain of activities, usually based on three main stages, that is: i) collection from households or recovery from MSW, ii) sorting and, finally, iii) mechanical recycling. This paper investigate the sorting logics, hyperspectral imaging...Read more

Solid waste management
The State of Qatar has recently launched its national vision (QNV2030) underlining, therein, its full commitment to retain harmony between the main three pillars of sustainable development: economic growth, social development and environmental management. However, rapid development and "mega...Read more
Improving the homogeneity of a sewage sludge-based phosphorus fertilizer by Monte Carlo simulation of the production chain
Vogt S., (Corresponding) Brueck F., Schnabel K., Weigand H.
Topic:
Solid waste management
Sewage sludge mono-incineration with subsequent phosphorus (P) recovery from the ash is becoming increasingly important in many European countries. Plant operators are facing the challenge to produce a homogeneous P output which needs to conform to fertilizer standards (including trace elements...Read more
