WASTE FACILITY DESIGN
A Leader in Waste Facility Design
Activities carried out at waste facilities include disposal, treatment, recycling and energy generation. They are a crucial part of ensuring we sustainably manage the wastes produced by households, commerce and industry. These facilities are varied and include mechanical, thermal, chemical and biological treatment of wastes, soil remediation plants and landfill disposal. Materials that cannot be recovered or recycled, including the residues from treatment facilities, are disposed of in a landfill. ByrneLooby has extensive experience providing complete design services for waste facilities or providing specialist inputs to larger development consortiums. Our team of multidisciplinary experts has delivered the design and master planning of nationally significant waste management projects in the UK and MENA region, including the 18 million cubic metre capacity, triple landfill Sohar Industrial Waste Handling and Treatment Facility (IWHTF) in Oman and at multiple, extensive scale waste management facilities over 20 years for the two leading waste management operators in the UK. We can also design the remediation works at former waste management facilities, including treatment plants where soil and water contamination has occurred and historical landfill sites.

PROJECT FOCUS: 30-YEAR MASTERPLAN FOR ONE OF THE LARGEST WASTE FACILITIES IN THE WORLD
SOHAR IWTF (INDUSTRIAL WASTE TREATMENT FACILITY) OMAN
50-Hectares Complex | 400,000 m3 Earthworks
OVERVIEW
We were appointed as lead landfill design engineers designing and delivering the 30-year masterplan of the Sohar Industrial Waste Handling and Treatment Facility (IWHTF), one of the world’s largest hazardous waste management facilities. This treatment facility will cater for a range of wastes, both hazardous and non-hazardous and is a cornerstone of integrated waste treatment facilities in Oman, servicing the entire country. Through the masterplan, spanning three decades, our team outline the most cost--effective, long-term pathway for any future landfill development phases. Three landfills were constructed providing 18 million m3 of void space on a 50-hectare complex. One of landfill sites will contain hazardous waste and it is composed of two composite liners. The other two other cells include single composite liners for non-hazardous wastes and inert wastes. Our team provided the detailed design for the first cells on each of the three landfills and supervised their construction.
A project of this size and scale included earthworks movement and the design of development platform of over 400,000m3 of soils, which requiresd detailed design, and geotechnical expertise. The photo of the hazardous waste cell shows the 8 geosynthetic layers in the engineered containment lining system, including 2 sets of HDPE/GCL, drainage and protective geotextiles.
INTEGRATED RISK BASED APPROACH
The brief on this Design & Build contract included tender support, site investigations, environmental monitoring, hydrogeological studies, facility master planning, earthworks design, landfill design, geosynthetics design, surface water management design, site based construction support (including CQA) and preparation of the operations, environmental monitoring and closure plans.

IZZ MUNICIPAL LANDFILL
OVERVIEW
Solid waste management is one of the top priorities of the Oman government and Be’ah was established by royal decree to manage and plan the solid waste strategy. As part of their strategy, aging dumpsites were closed and replaced with new large, regional, engineered containment landfills. The Izz Landfill facility services the Al Dakhiliya Governate, some 140km southwest of Muscat with Nizwa as its capital.
PRIMARY ROLE
From 2015-to 2019, ByrneLooby worked on behalf of Al Ahlia Environmental Services to provide a masterplan design for a 20 year, 4.8 million m³ extension to the existing MSW landfill and the detailed design for the first two phases of the project. Al Ahlia was contracted to construct these two phases to provide an initial 2 million m³ of sanitary landfill capacity, with associated infrastructure and two new leachate evaporation ponds (4000 m²). Our role included the supervision, quality assurance, and verification of the works and the preparation of the operational, monitoring, and closure plans.
INNOVATION / VALUE ADD
We also provided the design and specification of the leachate collection, pumping, and treatment systems; the landfill gas management system, environmental monitoring systems and the surface water management plan. In addition, we undertook the design of the additional infrastructure required for both the construction and operational phases of the landfill including 2-way asphalt roads, roundabouts, access ramps, wheel wash, fencing, and storage areas. Our experts prepared the technical specification and provided construction support to sign off all works to the highest standards. The engineering design included the preliminary / master plan which was pre-approved by Be’ah. This 20-year master plan included best practices for environmental monitoring and operations, as well as procedures and planning for the eventual closure. Throughout the process, our progress was presented to all stakeholders including Be’ah to ensure alignment and collaboration. The site was handed over progressively to the landfill operator as each phase was completed to ensure continuity of service to the local community.
