Abstract

The assessment of a municipal solid waste composting plant aims at the realisation of the material balance and the analysis of the operation of the processing sequence. A precise material balance makes it possible to carry out a fine economic analysis. The method suggested is based on the analysis of each equipment before the establishment of the total assessment of the platform. That allows, in the event of insufficient output quality, to target the interventions and to improve the output without blaming the totality of the processing line. To arrive there, standardised methods of sampling and characterisation of municipal solid waste and compost were adapted to intermediate flows. A database, for the error analysis according to the formulas of Gy, is proposed and the software BILCO is used for the establishment of the statistically coherent material balance. During our work, we tested the equipments most used in composting plants: the composting area, the screens with average mesh from 20 to 50 mm and with finer mesh from 8 to 15 mm, the selective conveyor, the densitometric table and the rotating drum. All the equipments are tested in real size, in different plants, except the rotating drum and the average screen  More>>

During our work, we tested the equipments most used in composting plants: the composting area, the screens with average mesh from 20 to 50 mm and with finer mesh from 8 to 15 mm, the selective conveyor, the densitometric table and the rotating drum. All the equipments are tested in real size, in different plants, except the rotating drum and the average screen which were the subject of a study at the laboratory. A simulation of screening at 20 mm shows it is possible to detect the origin of the sampling errors made at the time of the analysis of this kind of equipment. A composting pilot of 750 l was worked out, to follow the loss of mass and the CO{sub 2}, CH{sub 4}, NH{sub 3} and N{sub 2}O outputs, during composting in rotating drums. The results obtained by the tests on the experimental drum were validated on an industrial drum. The hypothesis of the conservation of the mineral matter during the composting and the accuracy of the total organic matter content determination (ignition loss at 550 deg. C) were the subject of a parallel test. From the studied equipments, a standard processing line of municipal solid waste composting is proposed and a simulation of treatment of waste in a small Breton facility is carried out. An alternative of the processing line is proposed to adapt it to the socio-economic context of the developing countries. (author)}
