The plasma gasification offers more benefits compared to the conventional gasification. Those benefits include the better environmental issue such as lower emission, variated feedstock and higher energy recovery, including hydrogen and waste heat. Waste to energy technology is developed as a means of waste management to obtain new and renewable energy, due to the increasingly amount of waste produced by the growing population. The feedstock use is municipal solid waste (MSW) from TPA Jatibarang in Semarang City, Central Java. Along with population growth, energy supply becoming a very crucial issue in the near future. Converting the waste to energy would overcome the two crucial issues at once. With high temperature, the plasma gas decompose the feedstock into its constituent element and within thermochemical equilibrium stoichiometry, the syngas was formed. This model was developed based on plasma arc technology and able to estimate the syngas composition, energy required for the reaction and also the CO2 emission. This study is to obtain the crucial parameter which was involved to get the highest of hydrogen, highest syngas yield, highest efficiencies along with lowest its emission. Results shows that, the use of 100% steam as gasifying agent and steam to waste ratio (SWR) of 34,48%, can produce 48,33% of H2, Syngas Yield is 9,26 Nm3/kg, Cold Gasification Efficiency is 58.60% and its emission is 0.864 kg/hr.

Heat and mass transfer as well as chemical reactions in technical processes can be enhanced by using electric fields. This paper provides an overview of current fundamental and applied research as well as potential technical applications of electric fields in energy and process engineering. This includes electrosprays, technical combustors as well as electrochemical reforming and plasma gasification of waste or biomass. Other emerging fields are plasma technologies for treatment of water, surfaces and gases including flue gases. In particle or aerosol-laden flows, plasmas are used to promote particle nucleation and surface growth for controlled nanomaterial synthesis. Furthermore, non-invasive diagnostics based on electromagnetic fields and electric fluid properties are relevant techniques for online control and optimization of technical processes. Finally, an overview of laser-based techniques is provided for studying electro-hydrodynamic effects, temperature, and species concentrations in plasma and electric-field enhanced processes.

However, some limitations of conventional steam gasification still need to be overcome, such as low-purity hydrogen, low reaction temperature, and high tar content. [5,6] Recently, thermal plasma gasification has been under active development. Plasma could provide extreme high temperature and high reactive species for intensification of gasification, which can decompose more than 90% organic components into syngas and break complex long-chain hydrocarbons down without catalysts. [7] Accordingly, the syngas from plasma gasification contains more hydrogen, less tar, and less contaminants than conventional gasification. [8] Hlína et al. [9] indicated that the concentration of tar in the wood plasma gasification syngas (<10 mg Nm −3) was much lower than that of conventional gasification. Luca et al. [10] theoretically demonstrated that the volume fractions of CO and H 2 in plasma gasification syngas were 8% and 7%, respectively, higher than those in entrained flow gasification syngas. A twostage steam plasma gasification process indicated that molar fractions of hydrogen in the product gases were well over 50% for six different types of biomass. [11] Rutberg et al. [12] reported a novel three-phase, steam-air plasma process of high caloric waste. The torch input power is 52-86 kW, and the molar fractions of H 2 and CO in the syngas are around 60% and 30%, respectively. These studies suggest that plasma gasification is a promising hydrogen production technology. There have been studies highlighting the impact of different operating variables on syngas properties during the plasma gasification. Zhang et al. [13] demonstrated that high-temperature steam had a positive impact on the overall gas yield and the lower heating value (LHV) of syngas. A parameter study based on a simulated PGM (plasma gasification melting) process suggested that plasma power, air feeding rate, and steam feeding rate were positive for energy and exergy efficiency. [14] Favas et al. [15] indicated that low temperatures had a more positive effect on the production of hydrogen, while high air equivalence ratio (ER) was not favorable to hydrogen production. However, integrated analysis of the different parameters cannot provide a complete picture of their effects. The synergy effects of different condition parameters and the internal mechanisms behind them need further investigation. Redundancy analysis (RDA) is a powerful chemometric tool for simultaneously evaluating Recently, thermal plasma gasification has attracted much attention due to hydrogen-rich syngas production. In this research, wood sawdust and high density polyethylene (HDPE) mixtures have been investigated under plasma steam gasification with various HDPE contents (0-100%), at different input plasma powers (16-24 kW) and varying steam flow/carbon flow (S/C) ratios (0.2-1.8). The single-factor analysis indicates that the real H 2 yield at 80 wt% HDPE is 23.99% higher than the theoretically calculated results. This significant improvement in hydrogen yield confirms the synergetic gasif...
