Case Study - Ash and slag transport system for integrated waste management plant
January 2023 - May 2024
South Clyde Energy Centre, Scotland
The South Clyde Energy Centre in Glasgow is an Energy-from-Waste (EfW) facility under construction and designed using state-of-the-art technology. It will be operational by the end of 2025 and will support Scotland's ban on landfill of municipal waste, which comes into force in the same year. The South Clyde Energy Centre will generate electricity from the incineration of household and commercial waste. When fully operational, the plant is expected to have an incineration capacity of 350,000 tons of waste per year, equivalent to the annual waste generated by approximately 700,000 people. In addition, the plant will have an electricity generation capacity of 45 MWe, which corresponds to the average annual electricity consumption of about 90,000 households. Loibl Förderanlagen GmbH is supplying the complete ash handling and slag transport system for the project.
Downstream of the deslaggers, conveyor chutes are installed which are equipped with a coarse parts discharge system. Particularly large parts such as car rims or room safes are sorted out in order not to overload the installed conveyor technology. The fines fall through the bars and are transferred to an adjacent troughed belt conveyor via a collecting chute. For the troughed belt conveyor, Loibl supplies the rising support structure including catwalk.
The slag enters the slag hall via a 120 m long slag conveyor belt. Here, a cross belt conveys the slag to a moving conveyor belt, which distributes the slag evenly into the slag bunkers below. All troughed belt conveyors used are equipped with a collecting tray to catch trickling material and water in order not to contaminate the areas below.

What is Energy-from-Waste?
Energy-from-Waste stands for the recovery of energy from waste incineration. Mixed waste always contains non-recyclable components. To prevent these materials from ending up in landfills, they are incinerated safely and with low emissions in waste incineration plants. The energy generated during incineration can be used to generate electricity as well as fed into the regional district heating network.
