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 in
the 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 %
Amount of waste in the EU 2007
recycled* incinerated/landfilled total
39 % Average in Europe
*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

WASTE TO ENERGY
STEP 2
OPTION 1

MBT
Sorting of the input material
Compression by using extruder press
example biogas plant
example example extruder press treatment plant

Extruder press
from
waste
to
energy
The heart of the process is the extruder press.
Different sizes for different tonnages from 100 t/d up to 3,500 t/d
Modular construction allows extension

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 press
Output of 15 t/h
Operating pressure 280 bar
max. 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 partners
Our partner is installing and operating biogas plants in e.g.,
Germany, Italy, Brazil and Croatia
Cooperation of well known companies for biogas plants

Biogas plant (example)

Resulting benefits
Production of high quality compost for the agriculture
Reduction of leachate from the landfill
Reduction of methane gas from the landfill
Extension of lifetime of the landfill
Easy sorting of the valuable material like paper, cardboard, plastics,
glass, etc., out of the dry rest refuse

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 output
from a fermentation box is
needed for the mixture with
the fresh incoming organic
waste.
The mixture remains in the
fermantation box for 4 weeks.
Filling and emptying is only
done 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.

percolate
exhaust air
1) installations room
2) gas storage
3) tunnel fermenter with gas sealed gate
4) automatic filling (option)
5) pump shaft with grit collector
6) percolate fermenter

- Eggersmann
Small digester for a throughput of up to 10 t per day

Goals for the client
The customer will become a benchmark in environmental politics
through:
Sustainable waste management (Faber Ambra®)
Waste to energy (Biogas, RDF)
Waste water to energy (Biogas)
Usage of secondary raw material
Environmental friendliness
Saving of space
Different options also in compost and anaerobic
technology
Benefit: Creating new jobs locally with
advanced, forward-looking technologies.

Creation of „good“ jobs

Cost efficiency

Legal basis
The legal basis is always adapted depending on the local legal
regulations and legal requirements.

Example: Legal framework in Germany
Political level
EU
Federal government
State government
Local council
Regulation
Waste directives
National waste law
State government waste law
Local bye-law
§

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 composition
of 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 company
MBS 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
the investment risk
the technological risk
the operational risk
Precondition for the BOT model are securities, guaranties, etc.

Costs and financing of resource management
The costs are made up of
the collection and transportation services
composting
recycling
evaluated by the public tender
the fees for landfilling or incineration charged by the District Council.
The costs are covered by
a standard fee per resident which includes all services for waste
management.
