This research was conducted for the purpose to overcome Indonesia waste problem. The samples are classified into garden waste, paper waste, wood, food waste, and MSW with objective to identify which type of waste give out more syngas since there is waste separation in Indonesia. All samples were treated by plasma gasification without pre-treatment (drying). Arc plasma torch used in this experiment was made by National Nuclear Energy Agency (BATAN) and used Argon as the gas source. Then the torch was connected to self-designed gasification chamber and gas washing system before injected into a gas bas for composition analysis. Another objective is to identify factors that may affect the gasification efficiency and the experiment shows that moisture content is not really affecting the efficiency but the duration of the process. The mass reduction of each samples were recorded, then the gas produced from the gasification process were analyzed. The result shows that food has the highest mass percentage reduced and producing the highest amount of hydrogen amongst other samples. However, treating MSW also produce considerably high amount of hydrogen. In conclusion, MSW direct treatment (without separation) using plasma gasification is feasible since it still produces desirable quality of syngas.

In recent studies, plasma gasification has shown great potential as an effective method for solid waste treatment and energy recovery. In this study, a plasma gasification process is simulated based on a chemical equilibrium model developed in Aspen Plus. The model takes into account the properties of different feedstock, used for gasification, and the input plasma energy and evaluates the output syngas composition following a Gibbs free energy minimization approach. The model is used to evaluate plasma gasification of three types of feedstock i.e. industrial waste (shredded tires), construction waste (plywood), and baseline bituminous coal. The process is optimized for two different types of plasma gas: air and steam. Process metrics are evaluated and compared for the considered feedstock. Results showed an obtained plasma gasification efficiency of 46.4% for shredded tires and 41.1% for plywood and bituminous coal. Energy recovery potential is also evaluated using an integrated plasma gasification combined cycle (IPGCC) power plant model. Thermal efficiencies of the process are evaluated and compared for the different feedstock. Plasma gasification of waste tire material resulted in an energy efficiency of 28.5%, while the efficiency for coal and plywood was lower at 20.0% and 18.3%, respectively.

Environmentally Friendly Process

Gasification is a technologically advanced and environmentally friendly process for solid waste treatment. The chemical reactions in the gasification process highly depend on the agents’ flow rates which, due to fluid dynamics and thermodynamics, are in fact functions of particle size and structure. Therefore, in order to obtain a better prediction model, it is important to determine the effect of particle size on the operation of a gasification system. The purpose of this research is to investigate the effect of particle size of some common solid waste on the gasification process. Specimens including starch and polyethylene of different sizes are investigated experimentally. To achieve the aim, the gasification processes are monitored by a thermal gravimetric analysis system. The mass change and the heat flow are measured in real time during the reaction. Comparison between the experimental results and different gasification models are made. Based on the experimental results, the effect of particle size was studied and the importance of the porous structure was revealed. The relationship between particle size and porous structure during gasification was developed.

As a rule, hazardous waste needs a pre-treatment, either a thermal or a chemical-physical one, before it can be disposed of at a landfill. The concentration of different kinds of treatment facilities at a Centralized Hazardous Waste Treatment Plant is advantageous. The facility of the ZVSMM at Schwabach is presented as an outstanding example of this kind of Treatment Centre. The infrastructure, the chemical-physical plant with separate lines for the treatment of organic and inorganic waste and the hazardous waste incinerator are described. Their functions are discussed in detail. Emphasis is laid on handling the residues produced by the different treatment processes and the final disposal.
