Mixed household waste is most often disposed of in landfills, and in some cases it is burned in thermal power plants for energy production. Such waste usually contains up to 30 percent plastic. Plastic melts at a temperature of 180 to 200 degrees Celsius. In order to use mixed household waste as raw material, it needs to be finely chopped and heated to 200 degrees Celsius. At a temperature of 100 degrees Celsius, biological waste dehydrates and small pores form in it. When the plastic melts, it enters the pores and thus turns the biological remains into inert waste. At the same time, the temperature must not exceed 250 degrees so that the biological remains do not char. From this mixture, it is possible to obtain very hard and solid objects such as garden tables, garden benches, fence posts, or long beams.
A possible procedure for the production of massive objects from mixed household waste;
During production, the waste must first be finely chopped and mixed. Then it should be inserted into a wide horizontal steel pipe with a slope of 5-15 degrees, so that the molten mass slowly flows towards the other end of the pipe.
There is a fire under the pipe that heats the pipe. At the lower end of the tube, a mixture of solid particles and melted plastic comes out and is poured into the molds. The molds should be on wheels so that they can be moved after they are filled with the melted mass of mixed municipal waste. Liquid waste could also be printed through presses, and thus different long profile elements could be obtained.
