“…Plastic waste degradation by means of chemical procedures is an interesting way to reduce the disposal of these residues while obtaining valuable products: monomers [1][2][3], chemical feedstocks [4][5][6][7][8] or fuels [9][10][11][12]. Recently, a two-step process comprising thermal cracking of the polymer followed by catalytic hydroreforming of the obtained oils has been devised for the production of transportation fuels [13].…”

“…BASF, Fuji Tech. Conrad., Hamburg Pyrolysis and BP have developed pyrolysis technology on fluidized layer [8,12]. The disadvantage of this method is on the one hand the need for a high temperature and a large amount of waste products that require further processing steps, so that they can be used for e.g.…”

Abstract. In the past years there has been an increase in production and consumption of plastics, which are widely used in many areas of life. Waste generated from this material are a challenge for the whole of society, regardless of awareness of sustainable development and its technological progress. Still the method of disposal of plastic waste are focused mainly on their storage and incineration, not using energy contained there. In this paper technology for plastic waste depolymerization with characteristics of fuel oil resulting in the process, as an alternative to traditional energy carriers such as: coal, fine coal or coke used in households will be presented. Oil has a high calorific value and no doubt could replace traditional solutions which use conventional energy sources. Furthermore, the fuel resulting from this process is sulfur-free and chemically pure. The paper presents the installation for plastics waste depolymerization used in selected Polish Institute of Plastics Processing, along with the ability to use the main thermocatalytic transformation product.

“…Ding and co-workers [57] obtained a liquid fraction from co-mingled plastics that exhibits a boiling point response close to that of commercial premium gasoline. More recently, Metecan et al [66] obtained a product with a yield in excess of 85 % (from the hydrocracking of high-density polyethylene) that approached the properties of a commercial naphtha. However, in the majority of these studies the catalyst has been poorly characterized, if at all.…”

Waste not, want not: The increase in waste polymer generation, which continues to exceed recycle, represents a critical environmental burden. However, plastic waste may be viewed as a potential resource and, with the correct treatment, can serve as hydrocarbon raw material or as fuel oil, as described in this Minireview.Effective waste management must address waste reduction, reuse, recovery, and recycle. The consumption of plastics continues to grow, and, while plastic recycle has seen a significant increase since the early 1990s, consumption still far exceeds recycle. However, waste plastic can be viewed as a potential resource and can serve, with the correct treatment, as hydrocarbon raw material or as fuel oil. This Minireview considers the role of catalysis in waste polymer reprocessing and provides a critical overview of the existing waste plastic treatment technologies. Thermal pyrolysis results in a random scissioning of the polymer chains, generating products with varying molecular weights. Catalytic degradation provides control over the product composition/distribution and serves to lower significantly the degradation temperature. Incineration of waste PVC is very energy demanding and can result in the formation of toxic chloro emissions. The efficacy of a catalytic transformation of PVC is also discussed.
