Initial Situation


Problems faced worldwide

Increasing amounts of waste with growing prosperity

Contamination of the ground water by uncontrolled landfilling

Climate damaging by methane emissions from uncontrolled landfills


Volume of landfilled waste

without separate collection

100 %

Residual waste


Pollution

Land/soil

Sea

Water


Status quo in a lot of countries

Federal Government Actions / Waste Law

Producer and owner of waste are under the obligation to recycle or dispose of waste materials.

Exception: Private households

The local council has the responsibility for managing domestic waste.

The local council can either sub-contract the responsibilities to third parties through a tender process or carry out the work directly.


Strategic Options


Targets of a sustainable resource management

most favoured

option

least favoured

option


Reduced volume of landfilled waste

with separate collection

Example: Germany

Organic waste ~ 35 %

Paper, cardboard ~ 20 %

Glass ~ 10 %Packaging waste material (DSD) ~ 7 %

Residual waste ~ 28 %


Historical development of the separate

collection in Germany

Example: Implementation of the multi bin system inthe local council Burbach, Germany

1976: One grey bin 240 L for residual waste

1984: One blue bin 240 L for paper/cardboard

One yellow bin 240 L for light packaging/PET

1985: Depot Containers for the central collection of glass

1998: One brown bin 240 L for garden and kitchen waste


Recycling quotas in the European Union

Germany 64 %

Bulgaria 0 %

39 % Average in Europe

Amount of waste in the EU 2007

recycled* incinerated/landfilled total

*inlcuding composting


Conservation of natural resources

Conservation of natural resources by the utilisation of secondary raw materials from waste:

1 t of WEEE substitutes 50 t copper ore

1 t waste glass replaces 1.06 t minerals

1 t iron scrap substitutes 2.33 t iron ore

1 t waste paper replaces 3.64 t wood

To get 1 g of gold 1 t of ore is needed

The gold content of 41 mobile phones is 1 g


Technical solutions


Example: Separate collection


Reduction of costs

Example Germany

The implementation of an intelligent system of collection and transportation can reduce costs significantly.

Example:

Grey bin (residual waste) 4 weeks

Blue bin (paper/cardboard) 4 weeks

Yellow bin (plastics/packaging) 4 weeks

Intensively ventilated brown bin (organic) 1-2 weeks

Depot containers (glass) 2-4 weeks


Advantages

Clean streets

Hygienic and user-friendly

Easy and quick handling of the bin system for the workers

OPTION 1


MBT

Sorting of the input material

Compression by using extruder press

example biogas plant

example treatment plantexample extruder press


Extruder press

from

wasteto

energy

Different sizes for different tonnages from 100 t/d up to 3,500 t/d

Modular construction allows extension

The heart of the process is the extruder press.


The waste press / RDF equipment is sourced

from our exclusive partner

Process description: extruder press and RDF production

Municipal solid waste is fed into the extruder press; the waste is pushed into the perforated cylindrical chamber of the extruder press and “squeezed” at a very high pressure. This way the wet fraction (50 - 55 % moisture) is separated from the dry fraction (18 - 22 % moisture).The pressure-extruded dry fraction is riddled in order to remove inert materials (crumbled by the extruder press) and then shredded using a hammer mill to obtain an homogeneous size.The RDF obtained is in compliance with the laws in force and sent to energy exploitation plants.

Technical specifications – extruder pressOutput of 15 t/hOperating pressure 280 barmax. length 20,000 mm; width 12,000 mm; height 5,000 mm

The biogas plant is sourced from a couple of

trusted turn-key providers

Process description – biogas production

The wet fraction after the extruder press, which has 60% moisture (Total Solid TS=40%) is conveyed the anaerobic digestion plant.The matter is pumped from the mixing tanks onto the top of the digester where the anaerobic digestion process occurs.The digested matter which is extracted from the digester bottom cone and is not used for the inoculation is pressed to remove excess water and then sent to the aerobic stabilisation process.During the aerobic stabilisation the matter is left to rest in static biocells with air insufflation for 3-4 weeks and then matured under a canopy for 60 days; the stabilised matter obtained is used as covering soil in landfill sites

Reference plants – our partnersOur partner is installing and operating biogas plants in e.g., Germany, Italy, Brazil and CroatiaCooperation of well known companies for biogas plantsReference cases/ performance data available to AMBRA

WASTE TO ENERGY

STEP 2

OPTION 2


Anaerobic treatment technologies

- Dry continuously processes

Dranco* Kompogas / Küttner

* (DRy ANaerobic COmposting)


Dranco process

– Dry continuously

Dranco plant in Hille

fermenter gas storage


Around 50 % of the outputfrom a fermentation box isneeded for the mixture with the fresh incoming organicwaste.

The mixture remains in the fermantation box for 4 weeks.

Filling and emptying is onlydone by wheelloader.

Dry dis-continuously process

- Bekon

Before a box can be opened it has to be CO2-purged in order to flush all methane out. This mixture goes to the power plant and is burned.

§


Profitability of the treatment plant

For the calculation of the profitability the decisive factors are:

The gate fee

The market price per kWh (purchase price and sale price)

Recycling (market price of the respective recycled material – paper, cardboard, metal, non-ferrous metal, glass, plastics)

Demand for and price of agricultural fertilizer

Saving of costs for the treatment of sewage (liquid and dry)

The market price of RDF material


Utilisation potential

RDF-Material

Average calorific level > 15,000 kJ/kg *

The caloric value depends on the compositionof the input material

Fertilizer

Liquid with ca. 15 - 20% solid material *

Option: Recycling

* Estimation, must be analyzed and calculated locally


Saving potential

Reduction of the volume of the landfill

� Reduction of the costs for the landfill

Reduction of follow-up costs for the landfill

Reduction of follow-up costs for ground water

Reduction of climate gas (CH4)

Reduction of the amount of polluted leachate

CDM is possible


Business Models


Option 1: Feasibility study

Evaluation of the situation through a feasibility study at the location.

� This is necessary because it is only possible and reasonable to work out a tailored solution if reliable data are available.

A feasibility study can be conducted by our sister companyMBS Business Consultants GmbH.


Option 2: Turn-key

Investment by municipality

AMBRA and partners are subcontractors and provide

Planning

Delivery

Implementation

Education

Quality control

Faber Ambra® system > Composting

Licence contract

Contract period: 15 years

Subcontracting model


Option 3: Build – Operate – Transfer (BOT)

Must be calculated after the MOU and the letter of exclusivity

Contract period: at the minimum 15 years

� To ensure the quality of the final product

AMBRA takes on
