Study of the co-pyrolysis of biomass and plastic wastes

Study of the slow batch pyrolysis of mixtures of plastics, tyres and forestry biomass wastes

“…Fig. 6 shows that the increase of reaction time seems to increase the alkanes content of the gas, while decreasing the production of CO 2 and CO. A similar trend was also observed in a previous work, when a pine and plastics wastes blend, with 30% (w/w) of pine was pyrolyzed at the same experimental conditions [18]. These experimental results seem to indicate that longer reaction times favored the recombination of smaller radicals to give compounds with higher molecular weight.…”

“…Comparing these results with those obtained in a previous work when only pine and plastics were pyrolyzed [18], also showed in Fig. 1, it can be observed that the addition of tyres to the mixture seemed to have increased the liquids yield and decreased the gas formation.…”

“…In a previous work [18] mixtures of residues of pine and plastics were pyrolyzed to study the effect of the experimental conditions on products yield and composition.…”

Thermogravimetric analysis of the pyrolysis characteristics and kinetics of plastics and biomass blends

“…Also biomass and coal have low hydrogen to carbon ratio and therefore gives low liquid yield. Most researchers have studied the co-pyrolysis of biomass/coal with plastics or synthetic polymers and obtained higher quantity and better quality of oil in comparison with those obtained from biomass or coal pyrolysis alone [3][4][5][6][7][8].…”

Towards cleaner technologies: emissions reduction, energy and waste minimisation, industrial implementation

“…The results are described in their paper ''Study of the Co-pyrolysis of Biomass and Plastic Wastes'' (Paradela et al 2008). The results showed that by adding a plastics mix the overall efficiency of the slow pyrolysis of pine could be improved.…”
