REnescience at Amagerforbrænding
By Project Manager Frank Hansen
2012
Agenda
1. Brief introduction to Amagerforbrænding
2. REnecience at Amagerforbrænding
3. Site visit REnescience
The owners of Amagerforbrænding
Amagerforbrænding is owned by the municipalities of Dragør, Frederiksberg, Hvidovre, Copenhagen, and Tårnby
- 730.000 inhabitants- 46.000 companies and
institutions
Business activitiesWaste to Energy plantRecycling Landfill

9 recycling stations Co-owned with VestforbrændingProduction of heat and electricity
110.000 tons in 2010- 73 % is recycled- 24 % is incinerated- 3 % is deposited
405.000 tons in 2010- District heating since 1970- Electricity since 1991- Heat supply for 80.000 households- Power supply for 50.000 households
78.000 tons in 2009Environmentally safe landfill
Amager Bakke• State-of-the-art environmental performance
• Modern and flexible design
• Urban integration
• Flagship Waste to Energy
REnescience –waste refinary Renewables, Science and Renaissance of the energy system
The objective of the REnescience project is upgrading of household waste for optimal use of the energy content and of the basic elements –with least environmental impact.

Project goalHousehold waste REnescience is waste refining
The goal is to develop a continuous process that adds value to the waste through :
1. Liquefication of the bio-degradable fraction for optimal separation and utilisation
2. Recycling of metals, glass and plastic
3. Energy recovery of burnable fraction
Separated in recyclable, bio-degradable and burnable materials
Recyclable•Metals•Glass•Plastic
Bio-degradable •Paper and card board
•Food waste•Garden waste
Burnable•Wood waste
•Textile•Plastic
Method for waste treatment of the future

Gain for society

High energy utilisation
• Possibility for storing the liquid fraction and use as needed - in term of time and location
• Production of a wide range of energy products i.e. biogas, bioethanol
• Biogas can be used for • heat and power production• feeding to the natural gas net work• Transport
• Power production in existing plants–
replacing coal/oil
Saving ressources
• Metal, plastic and glass are recycled
and not lost• Soil improvement (nutrients are
retained is residual from biogas
production)

REnescience – Technology spin-off
2005
Let’s see how this works out
Initial tests – batch reactor
50 kg batch processing with enzymes
Solid fraction with metal and plastics.
Liquid bioslurre suitable for biogas production

End products – after enzyme treatment
Solid fraction consisting of plastics and metals
Bio slurry
REnescience – pilot plant
The enzyme reactor is 16 m long and has a diameter of 2,5 m
In the heat reactor the waste is prepared for the enzyme treaement
Vibration sieve for separation of the liquid and the solid fraction
A pilot plant for treatment of 800 kg of waste per hour has been developed and build.Operation commenced in december 2009. The plant is located at Amagerforbrænding.

REnescience – EUDP funded research project
2009
Elements of current investigations:
1. Washing and drying of solid fraction2. Optimising autamatic controls3. Long term operation of pilot plant (7.000 timer)4. Reduction of enzyme consumption5. Odour reduction6. Recycling of solid fraction7. Biogas production8. Design og feasibility studie of 10t/time plant9. LCA Life Cycle Analysis
REnescience – EUDP funded Research project
2009
Preliminary results:• Biogas production: high biogas yields from bioslurry. Problematic contents
of phatalater. Low concentration of heavy metals• Enzyme process works well with ”un-sorted” municipal solid waste.• Recycling of plastics not solved as yet. Difficult to seperate from rest of
solid fraction. • LCA: comparable with best practise within waste incineration.• Odour problems needs to be solved.• Glass cannot be recovered.• Business case ??
