“…According to a study by Khan et al [149], steam gasification of palm kernel shells in fluidized-bed reactors produced 150 g H 2 /kg of H 2 . A similar H 2 production potential (150.9 g H 2 /kg) was observed by Ganza and Lee [148] in microwave plasma gasification of mixed plastic waste, which is equivalent to 15 wt% of the initial sample. Lower and higher values have also been reported in other studies.…”

Hydrogen is a versatile energy vector for a plethora of applications; nevertheless, its production from waste/residues is often overlooked. Gasification and subsequent conversion of the raw synthesis gas to hydrogen are an attractive alternative to produce renewable hydrogen. In this paper, recent developments in R&D on waste gasification (municipal solid waste, tires, plastic waste) are summarised, and an overview about suitable gasification processes is given. A literature survey indicated that a broad span of hydrogen relates to productivity depending on the feedstock, ranging from 15 to 300 g H2/kg of feedstock. Suitable gas treatment (upgrading and separation) is also covered, presenting both direct and indirect (chemical looping) concepts. Hydrogen production via gasification offers a high productivity potential. However, regulations, like frame conditions or subsidies, are necessary to bring the technology into the market.

“…The prevention and the reduction of plastic pollution can be achieved by supporting research toward sustainable plastic removal methods, by implementing policies and regulatory measures and by promoting recycling and waste management practices, although not free from potential contamination hazard [78]. Plastic waste might be removed physically or by physicochemical and biological methods [3], converted into hydrogen [79], recycled [80] or biodegraded by microorganisms like bacteria, algae and fungi [81][82][83]. The toxicity of plastics, as particles and as carriers of toxic chemicals and microorganisms, will soon embody an urgent concern, and as such should be addressed [84].…”

According to more than 200 scholarly publications, plastic pollution has been emerging as a major environmental concern in recent decades, and has been posing a relevant threat to ecosystems and global health. While the focus has primarily been on the physical, chemical and biological impacts of primary and secondary plastics, also for their ability to cross biological barriers within the human body, an additional hazard is represented by their association to heavy metals, used as additives. Metals are, in fact, added to plastics for their stabilizing actions. The examples of metal toxicity here reported are Antimony (Sb), Arsenic (As), Barium (Ba), Beryllium (Be), Cadmium (Cd), Chromium (Cr), Cobalt (Co), Copper (Cu), Iron (Fe), Lead (Pb), Manganese (Mn), Nickel (Ni), Selenium (Se), Vanadium (V) and Zinc (Zn). This chapter explores the toxicity of metals associated with plastic pollution in the environment, illustrating their potential consequences for the global ecological system, with prevalent focus on human health. The interdisciplinary approach, which includes environmental science, chemistry and toxicology, aims to enhance the understanding of this complex issue and highlight the urgent need for efficient mitigation strategies.
