Facilities, in which industrial and household organic waste, sewage treatment plant sludges, green waste, tree, shrub and bush trimming waste are processed into a highly valued product called compost.

  • 8 compost containers with a capacity of about 25 m3 each
  • 1 container with a biological filter
  • 1 compressor station container
  • 1 administrative container with a process controlling computer
  • 1 pipeline system for containers aeration and deaeration

  • Kneer modular container composting system with the efficiency from 3000 to 24000 tons a year
  • Channel composters

Horstmann offers a Kneer container composting system device, which uses the latest technology for composting organic parts of gathered waste. The technology optimizes biological processes taking place in nature with the help of technical means. Thanks to this, individual phases of the composting process take significantly less time. The process control is done by a host computer automatically.

Kneer modular container composters with the efficiency from 3000 to 24000 tons a year The modular structure of the system allows for constructing facilities with the average efficiency of 3 000 - 24 000 tons a year.

In cases of small amounts of waste, it is also possible to deliver a mobile facility with the efficiency of up to 300 tons a year.

The main purpose of this technology is to process industrial and household organic waste, sewage treatment plant sludges, green waste, tree, shrub and bush trimming waste into a highly valued humus product. The compost process begins from preparing, segregating and homogenizing delivered material. The harmful materials are removed.

Green waste, tree, shrub and bush trimming waste are grinded and mixed. The degree of automization of this technological stage can be freely chosen by the client. The degree of automization is usually agreed on after considering profitability issues, that depend on the total efficiency of the device.

When the first stage is finished, containers are filled with the material prepared for composting. The device designed for moving containers and providing appropriate amount of compost material ensures optimal course of the process. Filled up containers are moved by the dumper to the section where they are connected to the aeration and deaeration system. There an intensive humus process takes place.

The intensive composting phase lasts about 14 days and the whole process is controlled by a computer.

Depending on the demand for oxygen, the fresh air is provided fully automatically to the compost material.

The outlet air, which arises during the process, passes through a biological filter in order for unpleasant odour to be removed and then is freed to the atmosphere. Water, which arises during this process is gathered in a special container and provided to the compost container.

Organic material decomposition and the temperature 55-7 °C during the intensive composting process phase leads to material hygienization.

The fresh compost from the intensive composting process phase (humus of II or III degree) is biologically stable and free from unpleasant odour.

During the additional composting phase, which lasts 4-6 weeks, the compost in a pile becomes humus of IV or V degree.
