Assembly and a method for in situ processing of waste

An assembly for the in situ processing of waste, in particular for cleaning up a waste disposal site, to form a series of output flows, comprising:

• a sorting device for supplying and separating a waste flow into various partial flows, comprising a metals flow, a plastics flow, a glass flow, an organic flow and a chemical waste flow;
• a set of processing devices, comprising:
• a fermenting device for converting the organic flow into combustible biogases, provided with a fermenter inlet which is operationally connected to the sorting device, a biogas outlet which is connected to a biogas buffer, and a fermenter residual product outlet;
• a fluidized bed gasifier for converting carbon-comprising materials into combustible gaseous products, comprising a gasifier inlet which is operationally connected to the sorting device, and a gasifier outlet;
• a pyrolysis device for decomposing a flow of decomposable materials, such as the flow of chemical waste, into hydrocarbons and pyrolysis ash, comprising a pyrolysis inlet which is operationally connected to the sorting device and a pyrolysis outlet which is connected to a pyrolysis buffer;
• a control device comprising a measuring device for measuring the composition of the various waste flows from the sorting device, the measuring device comprising a weighing device for weighing the waste flow, the various partial flows and the residual flows, and the measuring device being operationally connected to a computer device and a data storage device for logging the measured data from the measuring device, an input device for inputting proportion of desired output flows from the assembly, a first regulator at the fermenter inlet, a second regulator at the gasifier inlet, and a third regulator at the pyrolysis inlet, the computer being provided with software for calculating, from the measured data and the proportion of the desired output flows, flows of material to be supplied to the devices, and controlling of the first, second and third regulator for providing calculated material flows flowing to the processing devices.

A method for processing waste, in particular for processing or cleaning up of a waste disposal site, comprising the steps:

• supplying a waste flow from a waste disposal site;
• separating the waste flow into different flows of reusable material, such as glass, metal and plastic and a flow of residual material, such as a flow of organic material, a flow of carbon-containing material and a flow of chemical waste;
• measuring parameters of the composition of the waste flow, of the flows of residual material and of the flows of reusable material, comprising the mass;
• inputting the measured parameters into a control device;
• inputting an end product demand or a proportion of end products into the control device;
• calculating from the input end product demand or the proportion of end products and the measured parameters a first, second and third flow of residual material;
• by means of the control device, controlling the supply of the first flow of residual material to a biogas device, the supply of the second flow of residual material to a fluidized bed device, and the supply of the third flow of residual material to a pyrolysis device.
