“…For this, it should be taken into account that at K = 0.5, the next excess energy P is introduced into reactor: (when recalculating to electrical energy to power PT). To determine the permissible content of the mineral part in the initial sewage sludge, it is necessary to use the relation (7). If there is a mineral mass in the composition of sewage sludge at a rate of M per 1 kg, the amount of excess energy produced is converted into electric energy, which will be P(1 -M), and it, in turn, can be consumed for vitrification according to (7).…”

The chapter is devoted to the development of technologies for the processing of carbonaceous wastes, including hazardous ones, using plasma energy sources. In particular, plasma-steam equipment provides complete environmental safety and high quality of the synthesis gas produced. Its application is also discussed to exclude the risk of environmental pollution by heavy metals, if they are contained in the recycled waste. The advantages of using oxygen instead of air as an additional reagent in gasification processes are underlined. It is shown that the proposed variant of the processing technology corresponds well to the general idea of numerous publications in the world scientific literature, known as the Waste-to-Energy. It has been shown that plasma equipment has significant advantages in terms of the commercialization of processes for the treatment of sewage sludge and some other hazardous waste.

“…There are other thermal waste conversion technologies that have been explored recently such as plasma‐arc or plasma‐torch gasification processes. Among these technologies microwave plasma gasification as well as microwave‐induced pyrolysis (MIP) are emerging as the most attractive alternatives due to their higher waste conversion and product yields and, at the same time, much lower energy consumption for the own process . MIP not only overcomes the disadvantages of CP methods, such as slow heating and necessity of feedstock shredding, but also improves the quality of the final pyrolysis products.…”

Organic wastes are a suitable feedstock for the production of value‐added products that have been insufficiently exploited due to their complexity, which challenges their transformation by conventional procedures. Gasification and pyrolysis of organic wastes can reduce this complexity by producing syngas (CO plus H2 and other C1 gases), which can be used as a valuable commodity by catalytic conversion into chemicals. However, the high cost and susceptibility to poisoning of chemical catalysts have encouraged research on biocatalysts that convert C1 components of syngas into different multi‐carbon compounds. Nowadays, research on syngas fermentation is receiving much attention in order to enhance the productivity of microorganisms by remodeling their metabolism and by optimizing the bioreactor operational conditions. This review highlights the new technical achievements of pyrolysis as well as the new biotechnological uses of syngas for the production of bulk chemicals and biopolymers, discussing the major bottlenecks that challenge syngas fermentation. © 2015 Society of Chemical Industry

“…Next to it, plasma can be applied to generate high‐purity syngas from waste. Thermal plasma units for the gasification of municipal solid waste are already operating on the commercial scale . The nonthermal plasma can be advantageously used for the conversion of waste biomass to syngas with low tar generation and with high energy recovery levels.…”
