The technology of composting must guarantee the material-chemical, biological and physical-technical reaction conditions essential for the rotting process. In this, the constituents of the input material and the C/N ratio play an important role. Maintaining optimum decomposition conditions is rendered difficult by the fact that the physical-technical reaction parameters partly exclude each other. These are: optimum humidity, adequate air/oxygen supply, large active surface, loose structure with sufficient decomposition volume. The processing of the raw refuse required to maintain the physical-technical reaction parameters can be carried out either by the conventional method of preliminary fragmentizing, sieving and mixing or else in conjunction with separating recycling in adapted systems. The latter procedure obviates some drawbacks which mainly result from the high expenditure required for preliminary fragmentation of the raw refuse. Moreover, presorting affords the possibility of reducing the heavy-metal content of the organic composing fraction and this approaches a solution to the noxa disposal problem which at present stands in the way of being accepted as an ecological waste disposal method.
堆肥技术必须确保腐烂过程所需的物质化学、生物和物理技术反应条件。在此过程中，输入材料的成分和碳氮比起着重要作用。由于物理技术反应参数在一定程度上相互排斥，因此难以维持最佳分解条件。这些参数包括：最佳湿度、充足的空气/氧气供应、大的活性表面、具有足够分解体积的松散结构。维持物理技术反应参数所需的原始垃圾处理，可以通过传统的初步破碎、筛分和混合方法进行，也可以在经过改进的系统中结合分离回收进行。后一种方法避免了一些主要由原始垃圾初步破碎所需的高成本导致的缺点。此外，预分拣有可能降低有机堆肥部分的重金属含量，这朝着解决目前阻碍其被接受为生态废物处理方法的有害物处置问题迈进了一步。
