CO<SUB>2</SUB> Recycling for a Carbon Resource

Resource-constrained flowshop scheduling with separate resource recycling operations

This paper considers the relocation problem arising from public re-development projects cast as a two-machine flowshop scheduling problem. In such a project, some buildings need to be torn down and re-constructed. The two processes of tearing down and re-constructing each building are often viewed as a single operation. However, under certain circumstances, the re-construction process, i.e., th...

High Value Carbon Materials from Pet Recycling

Polyethyleneterephthalate, PET, has become one of the major post-consumer plastic waste. In this work special attention was paid to minimising PET residues and to obtain a high value carbon material. Pyrolysis and subsequent activation of PET from post-consumer soft-drink bottles was performed. Activation was carried out at 925 oC under CO2 atmosphere to different burn-off degrees. Textural cha...

High Performance Carbon Dioxide Recycling for Supercritical Fluid Chromatography

Recycling carbon dioxide into concrete: a feasibility study

The feasibility of recycling carbon dioxide into concretes through their curing processes was investigated. The CO2 uptake capacities of four commonly used concrete building products: masonry block, paving stone, cement board and fiberboard, were evaluated. It was found that, based on the cement content used in the product, the uptake capacities of the four products ranged from 9.8% to 18.9% wh...

A THEORETICALLY CORRECT RESOURCE USAGE VISUALIZATION FOR THE RESOURCE-CONSTRAINED PROJECT SCHEDULING PROBLEM

The cumulative resource constraints of the resource-constrained project scheduling problem (RCPSP) do not treat the resource demands as geometric rectangles, that is, activities are not necessarily assigned to the same resource units over their processing times. In spite of this fact, most papers on resource-constrained project scheduling mainly in the motivation phase use a strip packing of re...
