Abstract: Disclosed is a process for producing a multimodal ethylene polymer composition suitable for producing films by blow moulding. The process comprises (i) copolymerising ethylene and an alpha-olefin comonomer in a first polymerisation step to produce a first ethylene copolymer (PE1); (ii) copolymerising ethylene and an alpha-olefin comonomer in a second polymerisation step in the presence of the first ethylene copolymer to produce a first ethylene polymer mixture (PEM1), wherein the MFR2 of PE1 is higher than the MFR2 of PEM1; and (iii) copolymerising ethylene and an alpha-olefin comonomer in a third polymerisation step in the presence of the PEM1 to produce a second ethylene polymer mixture (PEM2) having a density of from 915 to 925 kg/m3 and a melt flow rate MFR5 of from 0.3 to 5 g/10 min.

Abstract: The present invention generally relates to one or more compositions and methods for inhibiting the formation of gas hydrate agglomerates in a fluid. The fluid may be contained, for example, in an oil or gas pipeline or refinery.

Abstract: Methods of reclaiming plastic from plastic medical waste containers containing medical waste and manufacturing recycled medical devices are described. Recycled medical devices made from plastic medical waste containers containing medical waste are also described.

Abstract: For processing of noble metal-containing, moist recycling materials with an unknown noble metal content (hereinafter called “batch”), a moisture-binding agent is added for homogenisation and the batch is mixed with comminution of optionally pre-sent agglomerates to form a free-flowing and homogenous powder. Optionally, the following takes place subsequently for analysis: A at least one representative, volume-reduced sample is taken first of all, B the sample is dried, C the sample is optionally divided further and D the sample is analyzed and the noble metal content of the batch is calculated on the basis of the data a previously known or pre-calculated quantity of the moisture-binding agent being added before sampling (step A).

Abstract: A process for making a carbonous residue from scrap tires is disclosed. Tires are digested in an oil product. Steel and glass fibers are separated. A product enhancing additive comprising halogen based organic or inorganic compounds is added. The resulting carbonaceous material is then cured to create the final product. The produced carbonous residue is well suited for capture of mercury. The present invention has the benefits of providing a use for scrap tires that would otherwise require disposal in a landfill, and also produces a product useful for capturing a harmful element, thereby providing multiple environmental and economic benefits.
