Compost bagging machines, closed composting system

Closed Composting System

For a number of years now, public interest in composting of organic materials has been on the increase and composting technology is a proven technology for dealing with a major share of organic waste. This technology is widely accepted and applied by the government and business at a large scale. Yet, during the composting process, there is stil the issue of organic substances which,

  • produce a nasty odour
  • result in run-off which is hard to handle
  • cause dispersion problems

The solution for such materials are the so-cal ed closed composting systems. Usual y, these are large scale composting factories, requiring a substantial investment, which do not always provide the desired result. Until now, smal scale processing of organic materials in a closed system was a problem. For these cases, EURO BAGGING is now able to offer a solution by means of Closed Composting System (CCS).

What is CCS
EURO Bagging's CCS system is a patented composting technology for which the raw materials are mixed according to a certain ratio in large plastic Bags, so that the composting process is hardly affected by the influence of rain, wind and there is hardly any emission of odour. The process is based on the proper mixture of carbon and nitrogen within the materials and it is control ed by means of the temperature in conjunction with a forced supply of oxygen plus an appropriate dosage of bacteria. In comparison with traditional composting methods, CCS offers numerous advantages:

  • No, or almost no, emission of odours
  • No run-off
  • Space savings of up to 65%
  • Does not require additional handling which saves time and money
  • Does not require substantial investments in fixed assets
  • Since it is a ful y control ed process, it is 2 to 3 times faster
  • End product quality is manageable since the process is control able

CCS and Emission of Odour
Emission of odour is one of the main aspects regarding the environment and the location for composting of organic waste. In traditional systems this issue was difficult to handle and to control due to the open character of the process. The CCS is characterised by no, or hardly any, emission of odour. The manageable constant air flow in the Bag creates the optimum circumstances for aerobic activity due to which the composting process can take place without the production of disagreeable odours.

The whole process takes place within a closed system. Hence, the composting product is not exposed to the outside air. Moreover, the compost is not moved, so the material itself stays "at rest". In this way, the main causes of the actual emission of odours are eliminated.

CCS and Flexibility
The CCS offers optimal flexibility in regards to closed composting factories. The CCS is mobile, so in principle the process may be located anywhere. It is no longer necessary to transport materials over long distances. Location requirements for the CCS are minimal. The fol owing requirements are applicable for processing of approx. 200 tons of product:

  • a hardened surface area of 8 metres wide and 70 metres long
  • running water
  • electricity outlet

When the system may be leased from a custom farming company the investment in fixed assets (excluding the possible investment in concrete yarding) is minimal.

The CCS Process
Reducing material: The material to be composted must be reduced to a particle size of a maximum from 10 to 15 centimetres, depending on the kind of material.

Mixing material: Create a mix of various materials with a C:N ratio of 20-40/l.

Add water: Depending on the mix, add 50 to 60% water.

Fil bag: Fil the LDPE bag by means of the Compost bagging machine, and subsequently hook up the blower which provides the optimum oxygen supply.

Check the process: For 12 to 15 weeks the temperature has to be checked at regular intervals so that the process may be slightly adjusted if necessary.

Sieving: After the composting process the product must be sieved upon which the oversized fractions may be processed again.

End product: Now, the end result is a homogenous product which is suitable for many purposes.

  • Evaporation
  • Processing of fixed and liquid manure
  • "Purification" of soil

CM 1,5

img_slideshow_CM_1-5-newMachine serves for smaller composting plants, e.g. municipalities dealing with compost. There are 2 ways of machine's design, pulled either behind the tractor or behind the pick-up car. There is a its own engine at both cases so it means no need of additional powering machine/device. The machine can be easily operated by one personal. It is possible to supply remote control of machine's working cycle when the machine can be operated by operator of front/telescopic loader loading the machine by composting material. There is a hydraulic braking system for material's compactness inside the bag. There is 1 perforated aeration pipe inside the bag to aerate the material to be composted.

CM 2,4

img_slideshow_cm-2-4Machine serves for bigger composting plants. Due to machine's dimensions it is dedicated to run the machine at 1 desired place; however it is possible to pull the machine behind the tractor. There is a machine's own diesel engine so it means no need of additional powering device. There is a remote control as a standard for operating the machine straight from the loading loader's cabin.

CCS accessories

Integral parts of the right running Closed Composting System are following technical devices beside the type of Composting Machine:

  • Composting bags with the same diameter as Composting Machine
  • Perforated plastic aeration pipes
  • Aeration units
  • Thermometers
  • Air-escape valves
  • Regulating unit - in case of fully automatic aeration process

Composting bags
They are supplied with the same diameter as the composting machine, standard with the length of 60 meters. It is possible to supply any length for huge quantities of bags.

Aeration pipes
They serve to supply air inside the bag. Pipes are being inserted to the bag at the same time as composted material is being filled to the bag by composting machine. There is 1 pipe in case of CM1,5 machine; by machines CM2,4 and CM3,0 there are 2 pipes.

Aeration units
They serve to blow air to the aeration pipes and to ensure air supply to the composted material. Operator sets the time when the engines of blowing units are on or off manually or these times are controlled by regulating unit using the temperatures figures coming from thermometers.

They measure temperature of composted material. In case of manual regulation they are just for operator to check the temperature. Their outputs are inputs for regulation unit in case of automatic control.

Air-escape valves
They can be used as a place to put the thermometers in the bag to measure the temperature along with outlet of surplus air.

Regulation unit
It process data from thermometers and pursuant to the temperature it switches on or off the engines of the blowing units. By this it is possible to keep desired temperature of the composted material in between given range of temperatures.
