The aim of this paper is for the production oils processed in refineries to come from pyrolysis real waste high plastic content rejected by recycling industry Basque Country (Spain). Concretely, streams were collected (1) a light packaging sorting plant, (2) industry, and (3) treatment plant electrical electronic equipment (WEEE). influence pre-treatments (mechanical separation operations) temperature on yield quality liquid fraction evaluated. In order study pre-treatment effect, samples...
Waste valorisation through pyrolysis generates solid, liquid and gaseous fractions that need to be deeply characterised in order try recover secondary raw materials or chemicals. Depending on the waste process conditions, fraction obtained (so-called oil) can very complex. This work proposes a method quantitatively measure composition of oils coming from three types polymeric waste: (1) plastic packaging sorting plants municipal solid waste, (2) rich rejected electrical electronic equipment...
The generation of pyrolysis liquids and gases with poor quality is a limiting factor for the development recycling process fiber-reinforced plastic waste. In this article, life cycle assessment (LCA) an advanced two-step to recycle glass polyamide waste presented. First, solid pyrolyzed by heating up at 3 °C/min 500 °C in tank reactor. generated volatiles are subsequently thermally cracked 900 tubular packed bed able reclaim fibers similarly conventional one reactor pyrolysis, while...
Valorisation of chemical compounds derived from the thermal decomposition plastic matrix in fibre reinforced waste is claimed as crucial for cost-effective recycling this waste. This work, validated application a treatment (900 °C) to volatiles generated pyrolysis four end-of-life glass polyester fixed bed tubular reactor placed series with reactor. Thermal volatiles' improves current scenario by transforming hazardous liquids and low quality gas into almost non-existent aqueous liquid...
Composite recycling based on pyrolysis is usually only focused the recovery of fibres without plastic matrix valorisation. This work presents application authors' patented process towards H2 rich gas generation to two end-of-life epoxy composite waste and results are compared only-pyrolysis experiments. Main show: (1) yield increase in detriment collected liquid phase, (2) close 50 vol.%, (3) 90 vol.% jointly with CO CH4. Although halogens halide form need be eliminated from gases, has...
Waste generation is one of the greatest problems present times, and recycling carbon fibre reinforced composites big challenge to face. Currently, no resin valorisation done in thermal methods. However, when pyrolysis used, additional valuable compounds (syngas or H2-rich gas) could be obtained by upgrading generated vapours gases. This work presents thermodynamic kinetic multi-reaction modelling gases process Aspen Plus software. These models forecast theoretical in-between scenario a an...
Rejected streams emerging from waste sorting and recycling plants are still capable of being valorized by unconventional routes. This is the case plastic-rich fraction generated after treatment electrical electronic equipment (WEEE). However, material complexity this stream supposes a handicap when it comes to obtaining repetitive results in laboratory-scale processes. work aims highlight influence that pretreatment (mainly particle size reduction) real WEEE has on variability concentration...
The use of alternative fuels derived from residues in energy-intensive industries that rely on fossil can cause considerable energy cost savings, but also significant environmental benefits by conserving non-renewable resources and reducing waste disposal. However, the switching conventional to is challenging for industries, which require a sound understanding properties combustion characteristics fuel, order adequately adapt their industrial processes equipment its utilization. In this...
Waste from Electric and Electronic Equipment (WEEE) is a rapid growing waste stream, with an 18 wt.% increase 2014 to 2019.The great polymeric nature of this stream makes it prone be used as feed in processes for the production alternative fuels.However, presence halogens formula polymers lead their release when combusted, combined organic compounds, dioxins furans, strong pollutants humans environment.In work rejected WEEE recycling plant was studied determine suitability pyrolysis process...
