WASTE CONVERTER PLANT - GYÖNGYÖS, Hungary

Object of the investment

The purpose of the project is to treat safety the domestic and the industrial waste in the region, to utilize the calorific value of the waste and to convert the produced electrical- and heat energy into money. The used technology is based on a high-level and up-to-date melting gasification process, which was developed in Switzerland.

The TS SA is in possession of the most considerable experiences in the world. They have been doing research on the thermal waste treating processes; in addition they are operating a few great plants the Europe. The technology has several references in the world, among other things in Germany, in Italy and in Japan.

The used technology

At the beginning of the '90s, TS developed a process for thermal treatment of waste, aimed at achieving the highest possible quantity of recycled raw materials with the lowest possible emissions. The Company began testing the process in 1992 in a 100 tons per day industrial scale test plant in Fondotoce, Italy.

The first commercial plant was built in Karlsruhe, Germany in 1997/1998 and commissioned in 1999. The plant is comprised of three parallel processing lines with a total of 720 tons per day. In 1997 Kawasaki Steel Corp., Japan, acquired the license for the process. During the same year an order was received for the 2-line plant "Chiba Works", having a throughput of 150 tons per day. This plant was commissioned in September 1999. At the moment 5 plants are operating in Japan and 2 additional are under construction.

The general overview of a plant is shown in figure. The technology differs substantially from the traditional processes of the thermal treatment of waste. With the classic grate firing process, the energy contained in waste is transformed into thermal energy, i.e. hot flue gas, which is subsequently cooled down in heat exchangers and thus made usable. Ashes and filter dusts remain as residues. Depending on the process involved, dioxins and furans are produced in the exhaust gas by means of de-novo synthesis. Nitric oxides contained in the exhaust gas require an expensive gas treatment. In this process, on the contrary, the potential energy contained in the waste is mostly converted into chemical energy, synthesis gas. Many advantages of the process result from this substantial process difference.

The water condensed during the different phases of the gas treatment is led into the process water treatment. The process water undergoes a multiple stage treatment. Subsequently it is used for cooling purposes. The process does not produce any wastewater. The products of the waste treatment are syngas, sulphur, zinc and salt, which all can be used in other industrial processes.

The positive effects of the plant

The region will benefit a lot advantages from the operating plant.

• We can simply solve the serious waste problems in the region.

• The system does not require a special waste collecting structure. The plant has got its own separation system, which supports the various waste collecting processes like selective or poured. The present suppliers can work in the future, too. Of course we can help to organize the waste gathering if the competent persons require it.

• We can help to liquidate the old and filled up unordered landfills, which is endangering the cleanness of the local soil and groundwater.

• We do not need application capital from the local governments or the townspeople.

• The paid local tax edifies the cash desk of the town.

• The customers gets cheaper energy so-called green current. This helps the local firms' subsistence and the continuous activity.

• We can perform the very hard environmental regulations of EU. The emissions of the plant are practically zero.

• New capacity for work will be established in the building- and the operating period.

The negative effects of the plant

We have made all investigations and measurements in the detailed environmental effect study, which proved, the plant could be installed and operated without any pollutions of the environment. On the contrary the plant is able to improve the condition of the local environment, because we can help to treat the waste with high standards and liquidate the old and filled up unordered landfills.

Concluding

We should not forget: to make amends for the pollutions and contaminations is very difficult and frequently it is impossible!
