Solid waste management practices such as ocean dumping, open burning and uncontrolled l a n d f i l l s are now being banned in most areas. Even incinerators which are not equipped with adequate pollution control devices have been or are going to be shut down. The new approach i s to recover usable portions of s o l i d waste such as metals, glass and even paper while the remainder goes to l a n d f i l l s or i s burned in modern incinerators which may be furnished with moving grates, water walls for steam generation, e l e c t r i c precipitators, secondary combustion chambers, scrubbers and high stacks. Unfortunately most of the incinerator models are not geared to process industrial waste because of the higher heating value of such materials or the pollution problems resulting from the combustion. Saarberg Fernwaerme, a division of Saarbergwerke A.G. in Saarbruecken, Germany owns and operates several incinerators, which y i e l d steam for either d i s t r i c t heating or power generation. Since they are aware of the shortcomings of incinerators they wanted to build a p i l o t plant for waste gasification as an improvement. The West-German Federal Ministry of Research and Technology decided to carry 60% of this 5 m i l l i o n dollar project for reasons of energy conservation and pollution control. A p i l o t plant was b u i l t for an intake capacity of one ton per hour of s o l i d waste, which by now has been in operation for more than 2 months. The technical f e a s i b i l i t y has been established and now the design criteria have to be studied. This system consists of the following stages of operation as can be seen in F i g . 1.
