In this research, the degree and source of recyclates contamination with polycyclic aromatic hydrocarbons (PAH) was studied in eight different polyolefin recyclate samples; four originating from post-consumer packaging waste and four originating from a mixed source (post-industrial, post-commercial, and post-consumer). The aim was to assess the applicability of these recyclates in the different products' categories. Furthermore, the impact of previous contamination with PAH was excluded by analysing pure plastics before and after undergoing simulated recycling processes.

Fuel side costs are defined as the costs resulting from flue gas cleaning and by-products. To have reliable data, co-firing tests were conducted in two power plants (i.

Article Synopsis
- Many noniron metals are being used in industrial and environmental processes by integrating them into ferrite structures.
- The extent of incorporation of certain metals, like Ni(2+) and Cr(3+), during Fe(II) oxidation-induced precipitation at moderate temperatures is not fully understood.
- The study identifies maximum incorporation values for six metals in ferrites, indicating that these values are influenced by how quickly water exchanges in the hydration shells around the dissolved metal ions.
Iron-oxidation processes in an electroflocculation (electrocoagulation) cell.
J Hazard Mater
November 2009
The processes of iron oxidation in an electroflocculation cell were investigated for a pH range of 5-9 and electric currents of 0.05-0.4A (equivalent current densities of 8.
