How does it work?
1. Materials recovery and fuel preparation
- The plant will deal mainly with mixed waste from the west of Scotland which cannot be separated for recycling at source and would otherwise go to landfill
- In the Fuel Preparation & Materials Recovery Building advanced mechanical recycling technology is used to separate mixed materials that are delivered to the Lifetime Recycling Village
- This process enables mainly inorganic recyclables to be separated and segregated using a variety of machinery including lasers and optical recognition. This specialised technology separates and prepares material for the recycling and energy recovery stages
- The biomass fraction that remains is prepared by shredding and mixing to a consistent and approved fuel standard suitable for renewable energy conversion in the Green Energy Power Station
- Exposed waste handling will take place entirely within the enclosure of this building and the fuel will be containerised before leaving for the power station
2. Recycling
- Products that can be recycled, such as glass, metals and plastics, will be further sorted, separated and processed in the Recycling Building.
- These products will be supplied locally to the west of Scotland economy
- The company will undertake research to extend the potential for economic re-use of recyclate materials
3. Green energy power production
- The biomass fuel that has been prepared then enters the storage area inside our Green Energy Power Station
- Within 4 days, it is loaded into one of 24 thermal treatment units where it is combusted in an oxygen reduced atmosphere (gasified ) to produce gas
- The gas is carefully filtered and piped to burners that heat water boilers to make steam
- The steam in turn is used to make renewable electricity via 24 parallel steam turbines
4. Plasma vitrification
Plasma vitirification is a proven technology across several industrial applications with consent in the UK and installations in Taiwan and Japan
- In this configuration two plasma process units are the key to a waste recycling operation that leaves no residues that need to be landfilled
- The first unit within the Fuel Preparation & Materials Recovery Building provides a direct recycling route for glass, batteries and complex inorganic wastes contained within the separated fraction
- In a second unit within one of the power stations, the residues from the gasification process are fully reprocessed into useful industrial compounds or an inert glass for block manufacture
As you can see this is a complete recycling and remanufacturing process and this would be the first, sustainable, zero-waste, low carbon Recycling Village of its kind in Scotland.
