We are a company offering a modular mobile / semi mobile drum composting systems and complete household-waste recycling sites.
The systems are based upon 3 international patents, which are licensed exclusively by our company.
We have certified test on de watered activated sludge composting, organic fraction composting and oil spill cleaning of contaminated soil.
The single components of the unit are carried out mobile; a location change of the total unit is readily possible and the modular construction guarantees a later extension, the conformity to self-changing edge conditions and the consideration of experiences won in the business.
Our composting technology is able to transform organic material within 5 days into fresh grade III compost. The yearly throughput of per unit is from 5,000 to 15,000 t. Due to the modular setup a nearly unlimited daily and yearly material throughput is possible The characteristic energy consumption is less than 1 kW/t.
The unit is to be served by one person per shift and is fully computer controlled. The process is the material is completely hygienic and practically odor free.
For waste sorting a mechanical low impact system is used in order to make manual sorting easier. The mechanically cleared waste stream is passed further to a 2-lane manual sorting facility.
The manual sorting is performed using a high-tech shielded, climatized and "germ free" BioSphere® cabin, as the sorting conveyer belts run at the outside of the cabins
household waste problem in cities worldwide.
In almost all cities of Eastern Europe, Middle East, Africa, Asia and South America the occurring household waste (approx.100-400 kg per head and year) is stored on unsecured dumps.
The inherent health risks for the residents, as well as a permanently growing environmental awareness of the population, lead in many city administrations presently to a rethink. Many countries and cities searched for a meaningful and finance able disposal possibilities.
Based on the high investment costs and overhead, the building of conventional rubbish combustion concern is excluded.
The technology introduced in this project engages exclusively the sorting and processing of the occurring household waste. Through sorting of salvageable materials as well as iron metals and non-ferrous metals, paper, carton, glass, etc., the actual volume to be deposited reduces to about 10% of the exit volume. The materials won out of the sorting can be sold the steadily growing recycling industry worldwide. The proceeds obtained are used to the business and for refinancing of the unit.
The single components of the unit are carried out mobile; a location change of the total unit is readily possible.
For the separation of iron shares, magnets and for non-ferrous metals eddy-current separators are used. For the sorting of paper, glass and plastics, manual sorting cabins are used. The biological fraction group out of the household waste sorting is brought the mobile / semi mobile drum composting ORGANIC@System. After a process time between 4-6 days, the compost degree of III-IV is reached. After this time, the material is completely hygienic and practically odor free – after sieving it is suited for
the use in the agriculture or in the landscape building.
The manual sorting facility is has a 2 – lane setup, so that a redundant is given and possible still standing times are minimized. The aggregates / components are dimensioned in order to process the demanded quantity of 100,000 t/a in a 2-layer business (exception are the composts, here is the interpretation for 30,000 t/a). In a 3-layer business the unit can process 150,000 t/a household waste.
In general a mechanical – biological – refuse processing plant (MBP) with a modular construction is selected. The modular construction guarantees a later extension, the conformity to self-changing edge conditions and the consideration of experiences won in the business.
The two main procedure steps at a mechanical – biological – refuse processing plant are:
Sorting of refuse
Composting of organic fraction
The planning of the single procedure steps and the selection of the components results from technical and economic viewpoints.
1. Sorting of refuse
Waste sorting is essential in order to provide high quality recyclable material to the fast growing recycling industry. In order to ensure an adequate quality, a mechanical and manual procedure is needed.
1.1. Acceptance / pre-sighting
The acceptance of the household waste is made by weighting and registration at the entrance of the plant. After the delivery of the refuse, a manual and mechanical pre-sorting is made by a Bucket Screen or conveyer belts. It is necessary to sort-out contraries such as car batteries and large parts (refrigerators, herds, barrier wood, etc.).
The pre-sorted household waste is placed in a dosing / bag opening device by a bucket excavator. The layer height of the household waste is reduced and the subsequent sorting is later simplified.
1.2. Mechanical sorting
The mechanical sorting is done by a low impact system. The first step is “Wind sighting”, which uses a fast wind stream to separate light materials (like paper and foliage) from the waste.
The second step is to divide ferrous and non-ferrous - metals form the waste stream. High-quality ferrous irons and non-ferrous metals, above all aluminum and copper are gathered in different containers and are sold without any further processing.
This is done by high quality over-belt magnets for ferrous materials and with non-ferrous separators.
1.3. Manual sorting
The mechanically cleared waste stream is passed further to a 2-lane manual sorting facility. The manual sorting is performed using a high-tech shielded, climatized and “germ free” cabin, as the sorting conveyer belts run at the outside of the cabins. The goods are pushed manually from the belt to a container under the sorting cabin. The personal is sitting back to back, forming a “sorting pair”. Each person, pair is assigned to a special fraction of the waste, for example white, brown or green glass or
plastic PET-bottles. By this system a pure and high quality recyclable material is sorted out. Any recyclable material can be sorted out if desired.
After the fragile fractions, like glass, are separated manually, mechanical sieve machines are used to sort-out waste fractions smaller 10 mm. Most of this fraction consists of organic material and in a smaller portion of stones, sand, ash shares, broken glass etc. This sieved fraction will be added to the organic fraction and composted later. After composting the “unwanted” faction will be removed by sieving and wind-sighting before packing.
The sieved waste stream will be manually sorted in the next step and fraction like leather, wood, plastics, textiles, cartons and paper will extracted.
Compactable parliamentary groups such as paper, carton and foil are transferred to a bale press or extruder and are prepared for recycling.
At the end of the sorting line only organic material should stay on the conveyer belts, which is ready for grinding and composting.
Composting of the residual organic fraction is a fundamental aspect of a working recycling and waste sorting system, since the fraction is about 60-40% of the household waste volume. Compost is a valuable organic fertilizer needed in agriculture and land filling.
2.1. Preparation of organic fraction
Adding of green cut and shreddering of the organic waste fraction prior to composting is essential. Hereby the cellular structure is destroyed and the surface enlarged. Through the adding of minced green cut (structure material), the process is accelerated and the throughput is increased.
2.2. Composting technology
Composting is performed by the ORGANIC®System technology. This composting device is able to transform organic material within 5 days into fresh grade III compost. The yearly throughput of one aggregate is from 5,000 to 10,000t. The characteristic energy consumption is less than 1 kW/t. The unit is to be served by one person and is fully computer controlled.
2.3. Mechanical construction
The unit consists of one or more 13 m to 24 m long drum bodies. A drum body itself is subdivided in 4 to 8 modules, whereby all modules are connected over a joint hollow axis firmly together. All modules possess a round shape and are once again subdivides into 4 single chambers with a volume of about 4 m³.
2.4. Composting procedure
The ORGANIC®SYSTEM is to be assigned to the dynamic composting procedures. In contrast to other round or polygon drums the drum cross-section of the ORGANIC®System is subdivided. This results in up to 32 separate chambers that are filled separately with organic material. The separation of the chambers is made by perforated plates.
Through the perforation of the divided sheet metals, a permanent influence of the adjoining material is possible on each single chamber. A gradation of the dividing ground brings an additional enlargement of the contact area between the chambers, ensuring a good temperature transmission.
The manifold contact area and exchange area between the chambers and/or modules improve the start behavior of the process. Through the exchange of microorganisms, moisture, oxygen and warmth between the fresh material and the already available old material the process is accelerated.
The ventilation of the material is passive through the rotation of the drum. The amount of the revolutions can be selected freely.
At the chamber exterior walls, ventilation openings are mounted, that exchange fresh and used air through the material movement.
The construction enables an optimal progress of the biochemical processes, as the process specific parameters are in the system itself (moisture, temperature, bacteria tribes etc.). Possibly occurring fluid are caught in a tub installed under the drum. According to requirement, the fluid can be brought by means of a pump over the center axle again to the system.
Through the extensive self-regulation of the biochemical processes and the symmetrical distribution of the goods in the drum body very slight energy consumption arises.
