Canaway Fleming Architects has experience in the design of buildings and structures that are an integral part of process lead facilities. As lead consultant employing a multi-disciplinary engineering team, we provided architectural, engineering, programme and design management services for the design of a waste to energy facility in Makkah, Saudi Arabia. Our scope covered client briefing, stakeholder consultation, feasibility studies, planning, detail design, specification and project oversite (client side).


The largest facility of its kind in the world, the building stores, treats and processes animal waste stored in two 6,300m3 subterranean bunkers providing fuel to two 2,500kg rotary kilns. Waste ash is used as a fertiliser additive and primary phase heat used for energy generation. In addition processes included for 2,600m3 of dewatering and blood waste water treatment plant, formic dosing and blast cooling plant as part of the solid waste treatment.


The local geography, environmental sensitivities and extreme climate of the site provided challenges for the building design. External temperatures can reach in excess of 50oC and combined with a requirement to maintain internal temperatures in the waste storage bunkers at 5oC coupled with the presence of corrosive dosing chemicals in the enclosed atmosphere, the design, specification and performance of the building envelope was a priority to maintain a safe and stable working environment.


Externally emissions modelling was carried out to provide evidence for the proposed design of abatement systems and flue heights in this mountainous region, to meet pre specified clean air and environmental standards.
