Waste to Energy plantRecycling Landfill

4

9 recycling stations Co-owned with Vestforbrænding

Production 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

• 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 goal

Household 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

9

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 ??
