Case Study: Saving Landfill Space and Transport Costs

The Hajj — an important pilgrimage to Makkah for Muslims everywhere — produces roughly 10,000 tons of animal waste over the five day festival. Historically, this waste has been landfilled, but MOMRA contracted Matthews Environmental Solutions to provide an incineration solution, aiming to save on both landfill space and transport costs while protecting the local environment.

Matthews designed, built, and installed a 24-hour gas-fired rotary incineration plant capable of processing 5,000 kg/hr of animal waste.

This incineration solution steadily and efficiently burns through the pilgrimage’s waste material. The energy recovery system ferried 5.9MW of waste heat to the industrial boilers. The process reduces the mass of the waste by 95-96% and leaves a white, calcined ash with less than 3% carbon.

Finally, the flue gas abatement filtration and continuous emission monitoring systems ensure that the incinerator met all relevant environmental exhaust standards, including full compliance with the stringent European Waste Incineration Directive, preserving the health and comfort of locals and pilgrims alike.
