REnescience waste refinery

The main objective of this project was to prepare the first ever REnescience commercial scale demonstration plant to be ready for operation before 2013.

Project description
The REnescience technology is an innovative and revolutionary way of handling and transforming household waste into high value fuels whilst extracting reusable fractions achieving a more efficient and flexible power supply. This project will demonstrate and optimise continuous operation of a new 800 kg waste and hour plant and ensure the highest possible value of downstream fractions. Activities required to achieve our objectives: 1) Construction of a downstream fraction handling system; 2) Improvement of automation process control; 3) Documentation of technical, environmental and economic performance of core process, biogas and power production under long-term operation; 4) Reduction of cost through optimised water, energy and enzyme consumption. From this a commercial scale 10-30 ton per hour waste refinery is designed for investment decision by Amagerforbrænding and other potential clients
Results

With this project there has been developed a concept, were unsorted garbage can produce a biofluid from the organic content in the garbage, which can be used in an efficient and flexible energy production. Furthermore solid fractions are separated which are suitable for further separation with increased recycling as a result. The project has also demonstrated that REnescience technology is matured for upscaling to full-scale.

In the project the pilot-plant had over 7,000 hours of operation at the treatment of 800 kg waste / hour and the plant's individual process components have been optimized.

The central enzyme portion of the process is shown to function properly, and it has been shown that biogas production from bio liquid is very high. It is based on experience drawn up a detailed baseline design for the upcoming full-scale plant (10-20 T waste / hour)

The move towards commercialization of REnescience technology continues in a new EUDP project focusing on project maturity and design of a business case for a full-scale plant in the triangle. The project is implemented in cooperation with the municipalities in question (Vejle, Kolding, Fredericia and Middelfart).
